摘要： A communication network apparatus and method for routing communication signals form a source device to a receiving device. The apparatus performs only local processing on communication signals to thereby increase the speed of processing the signals. A plurality of the processing nodes is combined into a plurality of sub-networks that comprise the network apparatus. Each processing node of a sub-network need only process address information pertaining to the node's current layer, one layer above it, if any, and one layer below it, if any. Additionally, each processing node has associated communication signal frequencies/wavelengths that identify the processing node as the intended recipient of the communication signal.

摘要： Apparatus and methods implement aggregation frames and allocation frames. The aggregation frames include a plurality of MSDUs or fragments thereof aggregated or otherwise combined together. An aggregation frame makes more efficient use of the wireless communication resources. The allocation frame defines a plurality of time intervals. The allocation frame specifies a pair of stations that are permitted to communicate with each other during each time interval as well as the antenna configuration to be used for the communication. This permits stations to know ahead of time when they are to communicate, with which other stations and the antenna configuration that should be used. A buffered traffic field can also be added to the frames to specify how much data remains to be transmitted following the current frame. This enables network traffic to be scheduled more effectively.

摘要： A network includes an access point using a first protocol and a station using both the first protocol and a second protocol. The station uses the first protocol before a first threshold and a second protocol after the first threshold. A first duration between the second threshold and the first threshold is at least of sufficient length for the station to receive one data packet from the access point and send an acknowledgment. The station transmits to the access point a current clear-to-send packet at a current time during a current exchange based on success or failure of a previous exchange during which a previous clear-to-send packet was transmitted to the access point at a previous time.

摘要： A resynchronization method for use in a data communication system having a first device configured to transmit data at a symbol rate to a second device. The second device includes a Reed Solomon (RS) decoder having a RS lock indicator and a Moving Picture Experts Group (MPEG) Protocol Interface (MPI) having a MPI lock indicator, wherein the RS and MPI lock indicators are monitored. Four different states, defined by the values of the RS and MPI lock indicators, determine whether the data communication system will wait for the RS decoded and the MPI hardware block to resynchronize, whether an intermediate-subset of the channel acquisition algorithm is performed or whether the entire channel acquisition algorithm is performed. The method of resynchronization described herein recovers synchronization within a predetermined time without the layers above the physical link layer having knowledge.

摘要： A communication system between head-ends and end-users is provided which expands bandwidth and reliability. A concentrator receives communication signals from a head-end and forwards the received communication signals to one or more fiber nodes and/or one or more mini-fiber nodes. The concentrator demultiplexes/splits received signals for the mini-fiber nodes and the fiber nodes and forwards demultiplexed/split signals respectively. The mini-fiber nodes may combine signals received from the head-end with loop-back signals used for local medium access control prior to forwarding the signals to the end-users. Upstream data are received by the mini-fiber nodes and/or fiber node and transmitted to the concentrator. The concentrator multiplexes/couples the mini-fiber node and the fiber node upstream signals and forwards multiplexed/coupled signals to the head-end. Communication signals received from the mini-fiber nodes that are destined to other end-users also connected to the mini-fiber nodes may be routed by the concentrator without head-end interaction.

摘要： A restorable optical ring-network having a primary module, and a number of secondary modules connected by two fiber-optic rings is disclosed. By configuring the secondary modules to simultaneously transmit optical signals along a clockwise and counter-clockwise direction on a first fiber-optic ring, and further configuring the secondary modules to simultaneously receive optical signals from both a clockwise and counter-clockwise direction on a second fiber-optic ring, an optical ring-network can be constructed such that, if the optical ring-network fails at a particular point, restoration can be performed by a single switching operation at the primary module.
