Номер: US20120027020A1
Принадлежит: NEC Corp

A multiplexing apparatus stores fixed length data into which information signals supplied from channels are divided; determines an output channel by selecting the each channel cyclically; and acquires the fixed length data from the output channel based on a channel multiplexing ratio number to store the fixed length data in a payload in turn. Also, the multiplexing apparatus adds assignment information, which includes a channel arrangement of each channel of the fixed length data stored in the payload, to the payload. Further, the multiplexing apparatus creates a multiplexing frame by using the payload to transmit to a transmission channel. A demultiplexing apparatus detects the assignment information from the payload of the multiplexing frame received to the transmission channel; and creates distribution information for distributing the fixed length data to each channel based on the assignment information. Also, the demultiplexing apparatus detects the fixed length data from the payload to distribute the fixed length data to each channel based on the distribution information. Further, the demultiplexing apparatus couples the fixed length data to reproduce the information signal.

Transceivers may be dynamically configured responsive to the recognition of a service of input/output card to be serviced, to act as master or slave in channel bonding situations. Multiple link bundles may be supported, thereby allowing for redundant link bundles.

Embedded into the architecture is a control mechanism that provides for the management and administration of users who are to receive the real-time information. In the preferred embodiment, the information being delivered is high-quality audio. However, it could also be video, graphics, text or any other type of information that can be transmitted over a digital network. Preferably, there are multiple channels of information available simultaneously to be delivered to users, each channel consisting of an independent stream of information. A user chooses to tune in or tune out a particular channel, but does not choose the time at which the channel distributes its information. Advantageously, interactive (two-way) information can be incorporated into the system, multiple streams of information can be integrated for delivery to a user, and certain portions of the information being delivered can be tailored to the individual user.

A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.

Принадлежит: Koninklijke PTT Nederland NV

A device for effecting a modification in a stream of transmission blocks detects a transmission block to be modified and generates a detection signal via detection means, which comprises delay means for effecting a delay in the stream of transmission blocks. The device further comprises memory means for generating, in response to the detection signal, the modification to be applied, and combining means for combining the stream of transmission blocks and the modification to be applied, provided with a first input for receiving the stream of transmission blocks, with a second input for receiving the modification to be applied and with an output for generating a modified stream of transmission blocks. The combining means comprises switch-over means for coupling one of the inputs through to the output, as a function of the detection signal. Due to the use of the switch-over means and due to the delay means being a part of the detection means, the combining means can be bufferless.

Traffic manager for network switch port

Номер: US6959002B2
Принадлежит: Integrated Device Technology Inc

A traffic manager for a network switch input or output port stores incoming cells in a cell memory and later sends each cell out of its cell memory toward one of a set of forwarding resources such as, for example, another switch port or an output bus. Data in each cell references the particular forwarding resource to receive the cell. Each cell is assigned to one of several flow queues such that all cells assigned to the same flow queue are to be sent to the same forwarding resource. The traffic manager maintains a separate virtual output queue (VOQ) associated with each forwarding resource and periodically loads a flow queue (FQ) number identifying each flow queue into the VOQ associated with the forwarding resource that is to receive the cells assigned to that FQ. The traffic manager also periodically shifts an FQ ID out of each non-empty VOQ and forwards the longest-stored cell assigned to that FQ from the cell memory toward its intended forwarding resource. The traffic manager separately determines the rates at which it loads FQ IDs into VOQs and the rates at which it shifts FQ IDs out of each non-empty VOQ. Thus the traffic manager is able to separately control the rate at which cells of each flow queue are forwarded and the rate at which each forwarding resource receives cells.

Switching network

Номер: US4403321A
Автор: Johann Kruger
Принадлежит: US Philips Corp

A switching network used to connect a number of input lines to a number of output lines via an internal time-division multiplex line. A memory and a counter for repeatedly and cyclically addressing all the memory locations is provided. An output line which is connected to the internal time-division multiplex line by means of an address decoder, the address decoders being connected to the counter, is assigned to each memory location. The memory receives in each memory location the number assigned to an input line, the output of the memory being connected to each one of the number decoders for each input line, which each time decodes a different number. As a result thereof, after reading of an address, an output line is switched by an address decoder, is connected to the internal time-division multiplex line, this time-division multiplex line being connected to the input line via the number decoder which corresponds to the number stored in this location. When the switching network is used as a concentrator, the input lines, the subscriber's lines and the output lines are preferably the connections to the service modules of a subscriber's station in a remote time-division multiplex transmission system. The switching network is to a large extent of a modular construction and can therefore be easily extended.
