Determination and use of metrics in a domain name service (DNS) system

Номер: US20120179814A1
Автор: Ajit K. Gupta, Eric Sven-Johan Swildens, Richard David Day
Принадлежит: Akamai Technologies Inc

A method for determining metrics of a content delivery and global traffic management network provides service metric probes that determine the service availability and metric measurements of types of services provided by a content delivery machine. Latency probes are also provided for determining the latency of various servers within a network. The latency probe calculates, for example, the latency from its location to a client's location using the round trip time for sending a packet to the client to obtain the latency value for that client. DNS servers use the latency test results, along with traffic weightings, to determine a server to return for a given DNS name.

PHY BANDWIDTH ESTIMATION FROM BACKPRESSURE PATTERNS

Номер: US20130176880A1
Автор: Radulescu Codrut Radu
Принадлежит:

The present invention provides a system and method of determining available bandwidth at a physical layer (PHY) device at a server on a broadband network. A link layer controller of a master administrator adaptively polls a PHY device over a set of time intervals. During polling, the controller places a PHY device's address on a line of a bus and awaits a response from the PHY device. Based upon the response from the PHY device, the administrator can determine whether the PHY device has available bandwidth. The link layer controller uses this information to recalculate its polling scheme to better make use of the available bandwidth over the shared transmission medium to which each PHY device in the network is attached. 1. A method for determining available bandwidth at respective ones of a plurality of physical layer (PHY) devices , the method comprising the steps of:polling by a controller said respective ones of said plurality of PHY devices at respective time intervals determined using respective ones of a plurality of counters corresponding to said respective ones of said plurality of PHY devices;receiving at said controller a series of responses from at least a given one of said plurality of PHY devices, said responses being based on available bandwidth at said given PHY device; andcomparing said responses to determine an adjusted time interval for use in subsequent polling of said given PHY device;wherein said polling of said given PHY device comprises transmitting an inquiry as to a current status of an incoming packet buffer of said given PHY device;wherein determining a given time interval for polling of said given PHY device comprises loading the counter corresponding to said given PHY device with an initial value and transmitting the inquiry when the value of the counter corresponding to said given PHY device reaches a final value; andwherein the value of the counter corresponding to said given PHY device is changed responsive to polling of at least ...

A novel machine learning-based network analytics, troubleshoot, and self-healing system identifies and locates sources of data network problems autonomously within an entire end-to-end network topology of a network operator, while not necessitating human diagnosis of the data network problems. This system uniquely embeds a smart universal telemetry (SUT) as a quality-of-experience (QoE) parameter collection agent in intermediary transport-level network equipment and each end-user modem, which in turn enables on-demand collection of robust diagnostic data from all end-user modems and intermediary transport level nodes in a data network. By executing a machine learning (ML)-based artificial intelligence (AI) analytical module in a cloud-computing resource, the system then achieves autonomous identification and source pinpointing of network problems, and even self-repairs some machine-identified data network problems autonomously through remote software updates performed intelligently by the ML-based AI analytical module, if physical replacement of a network equipment is unnecessary to resolve such problems. 1.

In some embodiments, a capturing agent, executing on a first device in a network, can monitor a network flow associated with the first device. The first device can be, for example, a virtual machine, a hypervisor, a server, or a network device. Next, the capturing agent can generate a control flow based on the network flow. The control flow may include metadata that describes the network flow. The capturing agent can then determine which process executing on the first device is associated with the network flow and label the control flow with this information. Finally, the capturing agent can transmit the labeled control flow to a second device, such as a collector, in the network.

METHOD FOR DETERMINING METRICS OF A CONTENT DELIVERY AND GLOBAL TRAFFIC MANAGEMENT NETWORK

Автор: Day Richard David, Gupta Ajit K., Swildens Eric Sven-Johan
Принадлежит: AKAMAI TECHNOLOGIES, INC.

A method for determining metrics of a content delivery and global traffic management network provides service metric probes that determine the service availability and metric measurements of types of services provided by a content delivery machine. Latency probes are also provided for determining the latency of various servers within a network. Service metric probes consult a configuration file containing each DNS name in its area and the set of services. Each server in the network has a metric test associated with each service supported by the server which the service metric probes periodically performs metric tests on and records the metric test results which are periodically sent to all of the DNS servers in the network. DNS servers use the test result updates to determine the best server to return for a given DNS name. The latency probe calculates the latency from its location to a client's location using the round trip time for sending a packet to the client to obtain the latency value for that client. The latency probe updates the DNS servers with the clients' latency data. The DNS server uses the latency test data updates to determine the closest server to a client. 1. A process for determining server performance metrics in a network , comprising:determining service availability and metric measurements of types of services provided by a content delivery server using a service metric probe resident on a server;determining latency values for various content delivery servers within a network using a latency probe resident on a server;wherein the latency probe calculates a latency value from a location of the latency probe to a client's location; andwherein, for a given DNS name, a DNS server uses updates to the latency values and updates to the service availability and metric measurements to determine a content delivery server to return.2.

Embodiments of this application disclose a fault management method. In a slice network, if a first management unit determines fault information in the slice network, the first management unit may determine, based on the fault information and an association relationship between slices, potential fault information that may exist in the slice network. Because an association relationship between an NSI and an NSSI and an association relationship between an NSI and a service that are included in the slice network can reflect a network topology relationship between parts in the slice network, the potential fault information determined based on the association relationship can reflect impact of a fault on the slice network by using the network topology relationship. An embodiment of this application further discloses a related apparatus for fault management.

In one embodiment, a method determines first information from a component of a computing device to determine when receiving of one or more advertisements will affect an available bandwidth reading that is based on receiving of a media program. Then, the method dynamically disables a multiple bitrate algorithm based upon the first information such that a new bitrate version of the media program cannot be requested by the multiple bitrate algorithm for the media player. Second information is determined from the component of the computing device to determine when the available bandwidth reading will not be affected by receiving of the one or more advertisements. The method then dynamically enables the multiple bitrate algorithm based on the second information. The multiple bitrate algorithm is then allowed to request the different bitrate version of the media program based on the available bandwidth reading.
