Also Figure 2 shows a queue according to an embodiment of the present invention Priority Weighted Round Robin queue and account for is general outline.

2 also refers to surface, at least one queue output port of a network device (Queue) .can be set with.

Network device 4 output ports if there is a queue of, for example an example more specifically. off at the first and the second.

Network device queue of 4 output ports in the event of a one queue Priority using queue, remaining 3 using queue Weighted Round Robin (WRR) queue of assigned so that is exemplary with respect to.

Service priority the traffic Gold, Silver, Bronze, .can be grouped into a Best effort (BE).

Gold traffic queue Priority and which is allocated to the highest as a can be processed. I.e., packet is Priority in queue always even if other packet at a queue can be processed first.

Next traffic Gold Silver traffic has priority. However all the other traffic Silver Bronze or Best effort traffic than is the first queue including always, an assigned weight (weight) processed by traffic is Bronze selectively removed can be processed.

Weights is allocated traffic Bronze processed by traffic is Best effort selectively removed (weight) can be processed.

For example, traffic Silver Gold traffic uses is remaining 50% of the first dielectric block can be used and, traffic Bronze Gold traffic uses is remaining 30% of the first dielectric block may be used in a, remaining uses is traffic Gold Best effort traffic 20% of the first dielectric block can be set so that the using.. Therefore, first rather than traffic Bronze Silver traffic processing and higher, traffic Bronze Best effort traffic first rather than higher. that it can be processed.

According to of the present invention embodiment also Figure 3 shows a queue according service QoS maps for controlling order to explain the method.

Also 3 with a, switch output port using configuration protocol or CLI (Command Line Interface) x queue for a can establish a physical-layer connection (property) characteristics (S310).

More specifically, switch and data, the output port to 4 to x sets the queue of two, one of a queue Priority queue (Q1), (Q2, Q3, Q4) remaining 3 queue of a WRR (Weighted Round Robin) can be setting queue. Just, switch is outputted to x 4 queue for example setting the two but described, switch performance or a function which can be provided according to a queue can be set in the output port the number of and, can be varied, the WRR number of in a queue of the base plate is determined to 3 also can be one or more.

3 μm as established by WRR of queue (Q2, Q3, Q4) respectively (weight) weights to w1% (Q2), w2% (Q3), w3% (Q4) can be set to.

For example, the weight Q2 sets and, determining the weights the intermediate Q3, Q4 the weights. may be established.

X and data, the output port to switch the queues or pluralities of target characteristics to, existing queue set in the pico-cell information if the measured UV index is changed a parameter value characteristics together through status message to queue can be the computer system notifies the controller (S320).

Queue status messages which a change has been made since a queue state x output ports, queue list and queue list included in at a queue queue for a characteristic value such as may include file and the attribute information includes a queue. Wherein, queue characteristic value to test the corresponding devices by queue Priority queue or WRR WRR information and for on whether or not queue when the queue information about the (weight) weights may comprise an.

Controller received status message to queue from the switches the queues characteristic information from each queue characterization indicates how much of it is present since the service characteristics (Flow) flow according whether assigned to queue may be steered to any are for given service-classified queues can construct mapping table (S330).

Operating network contingent on the assigned to queue any according to each service response message is received service of importance based and packet delay of loss on the consideration of the sensitivity to determined a QoS policy.

For example, used in BcN (Broadband convergence Network) services or to the routing protocol of the notches has a very important Gold packets are directed to allocate queue Q1 is determined according to the pitch service, such as VoIP or IPTV service and is determined according to the pitch service Silver packets are important may assign queue Q2.

Furthermore, service or VPN VoD Bronze packets are directed to allocate queue Q3 is determined according to the pitch service, a Internet service generally Best effort service is determined according to the pitch may assign Q4 queue.

A service controller once table is constructed mapping-classified queues, flow is by the actual services may be may be mapped to corresponding queue (Flow entry) entry flow to can be produced for configurations or a (S340).

The (Flow entry) entry flow a flow packet flow and the associated Match field for the performing action Action field indicative of the rechargeable battery may have divided into.

For example, controller corresponding to packet routing protocol or BcN the Flow 1 routing the Q1, corresponding to packet IPTV embodiment or VoIP Flow 2 between the Q2 is passed, or VoD Flow 3 VPN packet corresponding to the device sends to the Q3, corresponding to Internet packet generally sent to the Q4 Flow 4 day is transmitted to a switch command for a flow to can construct entries.

The flow controller chip is performed by a floor entry, database table change notification flow them for enabling a user to transmit switch putting the message (S350).

Database table change notification flow from a controller switch of receiving a message contained therein flow entry list (Flow entry list) of the switch using can be updates the flow table (S360).

Therefore, action field is not sufficiently received packet matched with the corresponding flow set in the pico-cell information the corresponding output port of the action in accordance with the teachings the queues transmission queue can be control according to QoS characteristics. I.e., a service switch into different flow according allocation at a queue (for example, queue WRR or queue Priority) the QoS can be control (S370).

Figure 4 shows a queue status message to account for also according to an embodiment of the present invention is exemplary.

Also by referring to 4, switch is into a queue status message to for example. off at the first and the second.

X output port been is assigned queue of the 4, the characteristics (property) of Q1 and assigning Null Priorty Q can be assigning a value.

Q2 and assigning WRR received from the characteristic amount of (property) may assign an to a 50% value, received from the characteristic amount Q3 and assigning WRR (property) of 30% can be assigning a value, received from the characteristic amount Q4 and assigning a value for (property) WRR can be assigning 20%.

Furthermore, value in WRR is associated with a level n each queue according to the priority-of-service is defined on the volume and a traffic can be, even during operation of the it periodically collects the traffic able to change a value.

According to of the present invention embodiment also Figure 5 shows a change of state queue method for controlling QoS through to explain the order.

Also 5 refers to surface, a queue controller transmits to the switch message state change can be for controlling QoS.

Specifically, output port of a switch controller is the server does not receive the response queue of x (for example, Add/Modify/Delete) x output port in order a queue can be set in the queue/n ratio, capable of supporting or not more than a predetermined maximum number, such the setting information should the employee.

Controller to see setting information queue of the switch the queues setting information for enabling a user to transmit switch request message (S510). X parameters of the output port when one, and data, the output port to switch x queue for a setting information message to the controller for enabling a user to transmit (S520). Wherein, queue setting information message x and data, the output port to a queue can be set in the queue/n ratio, capable of supporting or not more than a predetermined maximum number, such the setting information may comprise an.

Furthermore, output port parameters instead the lower end of the 'ANY' x, having switch is all output port queue for a sends a setting information can be meaning month.

Specifically, switch a queue setting information request message to output port x of the base plate is determined to a maximum number in a queue, such as queue/n ratio, capable of supporting setting information included in a message to queue setting information for enabling a user to transmit the controller.

Similarly, queue setting information request-to-send message parameter output port if is set to 'ANY', switch all output port number/n ratio, capable of supporting the maximum queue queue, such as setting information list made in the shape of the controller for enabling a user to transmit.

According to switch all output port set for the maximum queue number queue/n ratio, capable of supporting, such the setting information may be loaded with same. This switch in the case of parameter output port 'ANY' number queue and maximal using queue/n ratio, capable of supporting, such the setting information can be send US of one side of the case.

And registers the setting information in a queue controller QoS corresponding response message is received after a certain service cues that can be and determines whether mapping (S530).

X to and data, the output port to switch 4 sets the queue of two, one of a queue Priority queue (Q1), (Q2, Q3, Q4) remaining 3 queue of a WRR (Weighted Round Robin) can be setting queue.

For example, controller used in BcN services or to the routing protocol of the notches has a very important Gold packets are directed to allocate queue Q1 maps service, or VoIP packets are important such as service and IPTV Silver WRR maps service (weight) weight queue having, among other things, may assign queue Q2.

Furthermore, service packets are VPN or VoD Bronze service maps a nuclear reactor having intermediate in queue WRR directed to allocate queue Q3, a Internet service generally Best effort service maps a nuclear reactor having low in queue WRR queue may assign Q4.

According to policy mapping-classified queues service QoS controller performing on the resultant structure, the queues reflect the to switch same state change message (S540) for enabling a user to transmit switch.

Queue state change message and data, the output port to output port parameter x, command (command), (property) characteristics for each queue list and queue may comprise an information. Wherein, command (command) has additional satellite (ADD) or, changing or deleting (DELETE) can exhibit to be (MODIFY). Furthermore, queue characteristics information in an illustrated one another with reference to the table of Figure 4 can be understood.

Queue from a controller switch state change signal of the caller into a digital output port x queue for a (S550) can establish a physical-layer connection characteristics.

For example, switch and data, the output port to only one housing in the in-queue (Q1) x the Priority Q of 3 neighboring track with the WRR (Weighted Round Robin) queue (Q2, Q3, Q4) sets the queue, Q2, Q3, Q4 (weight) weight of each w1%, w2%, of the base plate is determined to w3%.

X output port setting characteristic thereof queue for a vessel with a great overall height to switch a queue status message to controller for enabling a user to transmit (S560). Wherein, x and data, the output port to status messages queue, queue list and queue characteristics may include a value or the like to.

Controller from the switches after receiving the status message to queue QoS for a flow control which can produce entries (S570), database table change notification flow entries flow generated loads (S580) switches for enabling a user to transmit.

Therefore, a switch receives a message database table change notification flow the flow table (Flow table) for updating and (S590), actual QoS to the packet (S593) can be arranged to execute a vehicle

Queue according to of the present invention embodiment also Figure 6 shows a procedure for adding an account for order.

Also 6 with a, 'ADD' material to switch on the controller received the corresponding output port. may be added queue.

X to queue Q1 output port of a switch is assigned only one, the (property) characteristics of Q1 BE (Best Effort) when assigned to give to, for example, ..

This case, all packets are incoming x output port Q1 is processing the same through.

Controller QoS service system's request or the lamp is put, the switching according to change of a policy properties a queue and new, can add a a queue.

For example, a minimum traffic directions to the a particular destination a certain degree of bandwidth to secure a different values are whether a message or service system when requesting QoS policy from existing switch Q1 set in the pico-cell information to exclude the difference of Image quality processing requirements such signals Q5 and Q6, following readout one cannot new the. required the addition of a queue.

According to also 6, x output port response message is received QoS controller Q2 to deciding to and further, according to characteristics of Q2 max_rate=b and a min_rate=a bandwidth can be assigning (S610).

I.e., the Q2 a bps minimum bandwidth traffic (kbps, Mbps) (for example, output port x is 1Gbps if port, a × 10Mbps minimum vapor deposition) while guaranteeing, b bps maximum bandwidth (kbps, Mbps) (for example, output port x is if port 1Gbps, b × 10Mbps maximum bandwidth) limit the can be provide the means by which.

A queue controller for enabling a user to transmit switch message state change (S620). Wherein, and data, the output port to message state change queue x, new queue (command) to be ADD, to add the adding and id queues (property) of characteristics for a in a queue the parameters such as the information may comprise an. Therefore, further a queue and new (ADD) to be including queue state change message in the output port x to adds Q2, Q2 and the third power supply x output port is minimum bandwidth (min_rate) and a % of the maximum transfer rate of, maximum bandwidth x output port is (max_rate) b % of the maximum transfer rate of can be is set to obtain.

More specifically, from a controller switch after receiving a message state change queue output port Q2 to x further setting can be (S630). For example, two x output port queue (Q1, Q2) can be set with..

X output port (Q2) a queue and new vessel with a great overall height to setting, switch a queue status message to controller for enabling a user to transmit (S640). Wherein, x and data, the output port to status messages queue, queue list (property) characteristics and queue (Q1, Q2) may include a value or the like to.

Controller from the switches after receiving the status message to queue, refer to the QoS control for a flow entry (Flow entry) may generate (S650).

For example, controller a destination (Dest. IP) in all directions to the 10.1.1.0 x output port packets sent to Q2 of entries flow that can be produced.

Controller a new flow entry chip is performed by a floor, database table change notification flow same switches for enabling a user to transmit loads (S660). Wherein, flow database table change notification message a new flow entry and flow table (command) to be (ADD) added to the parameters such as the may comprise an.

A switch receives a message database table change notification flow the flow table entry flow received new, can add a (S670). Therefore, destination for incoming packets to a switch switch (Dest. IP) in all directions to the 10.1.1.0 x output port packets are by transferring the touch action of the characteristics of Q2 of Q2 can be control (property) according to QoS (S680).

According to of the present invention embodiment also Figure 7 shows a method of procedure to delete queue account for order.

Also 7 with a, 'DELETE' material to switch on the controller the transmission command at the output port queue are capable of erasing the..

X output port of a switch Q2 and Q1 the current is is assigned two queue, characteristics of Q1 BE (Best Effort) is assigned to the (property), Q2 properties of the minimum width of the maximum transfer rate of x a % (min_rate=a) to output port, a maximum bandwidth x output port assigned to b % (max_rate=b) of the maximum transfer rate of for example when the described example.

QoS's request or service system controller according to change of a policy the lamp is put, the switching is set at are deleted in a queue may it determines (S710). For example, a particular minimized to the traffic directions to the server a certain degree of bandwidth to secure a longer according to the transformation of the diaphragm service server multivalent secure the band width is do not need to exclude the difference of Image quality. Furthermore, specific directions to the customer site a certain degree of minimized to the traffic to secure a bandwidth so or multivalent customer service for guaranteeing minimum bandwidth changes a can be it has become unnecessary. X output port of a switch if the Q2 set in the pico-cell information are deleted is necessary that.

X output port of the switch controller for deleting Q2 in deciding decide queue state change message (S720) for enabling a user to transmit switch. Wherein, x and data, the output port to message state change queue, queue (command) to be DELETE, id queue to be deleted the parameters such as the may comprise an.

Switch state change queue from a controller output port after receiving a message in x. are capable of erasing the Q2 (S730). X output port thus two queue Q1 (Q1, Q2) may be cleared and is Q2 in the capacity ratio thereof can reach there are any.

Q2 switch, is complete a deletion to a queue status message to controller for enabling a user to transmit (S740). Wherein, x and data, the output port to status messages queue, queue list (Q1), queue characteristics (property) may include a value or the like to.

Furthermore, a flow switch Q2 of x output port in the table associated with and for deleting entries flow (S750), flow entry deleted message to the controller for enabling a user to transmit (S760).

Deleted entry flow from the switches controller after receiving a message for deleting entries can be corresponding flow (S770).

For example, switch a destination (Dest. IP) in all directions to the 10.1.1.0 x output port packets sent to that of Q2 can be for deleting entries flow. Therefore, output port of a switch Q1 packets are all incoming x may be used can be processed to BE (Best Effort) (S780).

Figure 8 shows a also of the present invention embodiment rate lost packet according to the queues based account procedure of altering properties for order.

Also 8 with a, to a switch controller QoS as well as change of a policy, overall traffic situations under an as-needed basis through the analyzing set in the pico-cell information queue characteristics can change the (property).

For example, output port queue WRR x to if is applied, into queues according to traffic situations (weight) weights of a a flexible (flexible) can be change of the face plate.

More specifically, controller periodically queue statistics request message transmission switch the queues for traffic statistics requesting data (S810) can be. Wherein, corresponding output port queue statistics request, queue id the parameters such as the may comprise an.

Switch a queue statistics request message corresponding according to statistics of the traffic queue including queue statistics message to the controller for enabling a user to transmit (S820). Wherein, and data, the output port to statistics message queue, queue id, number and transport packets may include water lost packet.

A queue controller corresponding signal of the caller into a digital statistics for the queue and. and is capable of calculating the packet loss (S830). Wherein, packet loss loss packet numbers when / (transmission packet numbers when loss packet numbers when +) can be a calculation is performed, as a.

A queue controller of each queue various kinds of loss as compared to a threshold value, the DAC receives a grayscale voltage can change the weights of a WRR queue (S830).

For example, if with a possible time delay in initial service environment to provide a high-Silver than was expected be increased as much as the quality of service assigned to service Silver Q2 lowers weights of a more change before outputs a relay driving signal. is capable of processing a traffic.

A control signal is inputted to the characteristics a queue controller queue characteristic thereof switches loads state change queue information for enabling a user to transmit (S840). Wherein, x and data, the output port to message state change queue, queue of altering properties (MODIFY) to be (command), queue to be change id and queue characteristic thereof the parameters such as the information may comprise an.

Switch a queue state change message according to the weight for each queue (S850) changes the, result to the computer of the a queue state loads (S860) in the controller for enabling a user to transmit. For example, a queue WRR switch Q2, Q3, Q4 w1% weights been applied to, w2%, y1% each of w3%, y2%, can be showing a used state of the plcm y3%.

Figure 9 shows a of the present invention embodiment also assigned traffic server 2001 according to different procedures mapping at a queue account for order.

Also refers to surface 9, controller key for converting a mode traffic is servers to remain differentially with the traffic general data are queued to processing can be mapping the.

First, switch to an output port that queue queue and set can be transient engine speed period is each set characteristics of (S910). Controller switch by receiving status message to queue from the switches set in at a queue can be sharing state (S920).

According to policy QoS controller critical traffic is servers to remain differentially with the traffic general data are for the queue mapping table can construct (S930).

For example, traffic directions to the SDN Controller controller therefor are subjected to treatment with service Silver Q2 to maps, traffic directions to the SIP Call Server Bronze Q3 to therefor are subjected to treatment with service can be mapped to.

Servers queue for a key for converting a mode controller for formation of cancer-metastasis blood mapping table, an actual flow (Flow) is read from stored information may be may be mapped to queue entries flow to can be produced (S940).

For example, the IP address 10.1.1.1 SDN Controller switch and the use of TCP for connection port using yyyy to and the technique assumes that, using the SIP Call Server IP address 20.1.1.1 TCP and the terminal for connection port using zzzz to the technique assumes that. disclosed.

The flow entry flow generated controller (Flow) are electrically connected to the conductive pattern Match field and the associated flow packet for the Action field indicative of whether performing action can be constructed is divided into.

For example, the aim flow of traffic to to SDN Controller (destination) IP and a port 22 source can be a the port and a (source) IP representing the Any can be represented by '*', may be one flow of traffic to to SIP Call Server (destination) IP and a port 22 source can be a the port and a (source) IP can be represented by '*'.

Furthermore, the SDN Controller Action field Q2 is passed to the traffic flow, traffic flow directions to the SIP Call Server Action that sent to Q3 may include a.

The flow controller chip is performed by a floor entry, database table change notification flow same switches for enabling a user to transmit loads (S950).

Database table change notification flow from a controller switch receives the message and, flow entry flow contained in a message database table change notification of the switch using table flow. is capable of updating (S960).

Therefore, switch output port is not sufficiently received packet directions to the SDN Controller x of Q2 by transferring the touch action of the treatment of the traffic Silver of WRR, directions to the SIP Call Server x output port is not sufficiently received packet by transferring the touch action of the Q3 of traffic Bronze of WRR can be processing, the corresponding queue (property) according to QoS characteristics (S970) can be control.

According to of the present invention embodiment also Figure 10 shows a network QoS maps queue according for controlling and order to explain the method, according to Figure 11 of the present invention embodiment for mapping a moment when a network queue according to illustrate the general outline is for.

Also with a 10, controller as a switch that a QoS type of network by linking can be control.

First, switch to an output port that queue queue and set can be transient engine speed period is each set characteristics of (S1010). Controller switch by receiving status message to queue from the switches set in at a queue can be sharing state (S1020).

Controller reference to status message to a queue according to other network QoS policy jig is mounted on the jig in a queue (S1030) can construct mapping table.

For example, radio access 4G or 3G controller wireless Internet incoming from the network for traffic Silver maps Q2 to process service, a wireless Internet incoming WIBRO radio access from the network for traffic Bronze service to process the mapped to Q3, wired access from the network to a wired Internet traffic incoming BE (Best Effort) Q4 to process service can be mapped to.

Correlate with generally same for processing data which have been instructed cost is 3G/4G and blocks is defined, for example, wireless Internet, next WIBRO are highly Internet, wired Internet. lowest. Therefore, are hydrophobicized by treatment with service Silver 3G/4G wireless Internet, and by applying treatment with sulfur service Bronze WIBRO wireless Internet, wired Internet QoS policy clinician to develop BE (Best Effort) and to process service, QoS each kind network by the controller based on policy can be for controlling QoS.

According of differentiating traffic network controller can be queued to mapping table is constructed on the resultant structure, an actual flow is read from stored information may be may be mapped to queue entries a flow to can be produced (S1040).

Also 10 and 11 with a, of the switch traffic wireless Internet 3G/4G and comes into Ingress 1, which entering Ingress 2 WIBRO wireless Internet traffic, traffic wire Internet through a terminal management system to entering Ingress 3.

For example, controller and data, the output port to the flow comes into Ingress 1 of Match field x Action field of a predetermined transfer Q2, and data, the output port to the flow entering Ingress 2 Match field of Q3 x Action field of determining the transfer, and data, the output port to the flow entering Ingress 3 Match field of Q4 of x Action field transfer. may be established.

The flow controller after generating the entry, database table change notification flow same switches for enabling a user to transmit loads (S1050).

Database table change notification flow from a controller switch receives the message and, flow entry flow contained in a message database table change notification of the switch using flow. is capable of updating table.

Therefore, wireless Internet packet 3G/4G Ingress 1 switch incoming from the output port by transferring the touch action of the Q2 of x Silver of WRR are hydrophobicized by treatment with service, wireless Internet packet WIBRO bores Ingress 2 x of the output port by transferring the touch action of the Q3 and by applying treatment with sulfur service Bronze of WRR, Ingress 3 bores of x output port packet wire Internet through a terminal management system by transferring the touch action of the Q4 of WRR BE (Best Effort) by treatment with service, QoS according network (S1060) can be control.

The above-mentioned according to an embodiment of the present invention, open flow switch according to each service in controlling QoS through differentially traffic can be.

Furthermore, according to an embodiment of the present invention, flow switch making open a WRR (Weighted Round Robin) method applied to various services according to traffic characteristics of differentiating treated.

Furthermore, according to an embodiment of the present invention, when state has changed queue, respectively, on the switch by, deviation of recording medium by notifying the prompt controller, network controller or policy is operating according to traffic situations state queue of the switch can be effectively changing the, effectively through QoS can be control.

Thereby, the cold air flows to standardize the reference to a preferred embodiment of the present invention not described but, corresponding art patent the following is claimed is a classic mirror server one skilled in the art of the present invention is a concept and region within such a range that causes no away from the present invention various modified and change can be 2000 database for each consumer.
