摘要： A congestion control method and apparatus for use with a communications link comprising a plurality of N channels. A plurality of at most N-1 queues are sequentially polled, and data is output therefrom to the communications link, thereby leaving at least one remaining channel. After the at most N-1 queues are polled, a determination is made as to which of the at most N-1 queues is closest to a data overflow condition. The remaining at least one channel is then utilized to transmit data from the queues which are closest to overflow.

摘要： The present invention concerns a method and apparatus for memory and channel sharing in a communication switching network which uses packet switching. In one form of the invention memory and channel sharing is provided within a packet switch. The packet switch includes a memory for storing a plurality data packets and a router that routes data packets from the memory to a particular output port. The router is operable to route data packets to either a dedicated output port, in other words, an output port defined by the virtual circuit path of the data packet, or a shared output port. In another form of the invention memory and channel sharing is provided by a packet switch in conjunction with a terminal. Protection lines which are provided in transmission systems can be used as the shared channels.

摘要： A plurality of M receivers are utilized to receive a plurality of N channels from various incoming multiplexed data signals, N.gtoreq.M, where each incoming data signal arrives on a separate wavelength and comprises several channels. Each of the M receivers, in sequence, receives a separate one of the N channels, thereby M of the N channels. The process then repeats for the next M channels, in the same sequence as the first M channels. The repetitions continue until all N channels are received.

摘要： A cross connect network is utilized in order to switch packets of information among a plurality of network nodes. Each of the plurality of network nodes generates a multiplexed data signal, where each multiplexed data signal includes several channels. The cross connect network routes the data packets based upon which channel each packet is in when it arrives from the network node, rather than based upon the address in each packet. Thus, the need to read the address and switch the packet at each switching stage in the cross connect network is eliminated.

摘要： A system and method for optimizing usage of a communications transmission medium. The transmission medium may be sliced into time and frequency domains so as to create time-frequency slices for assignment to users having varying access rates and user-application requirements. Through scheduling of the various speed users within the frequency and time domains, the system and method can efficiently allocate and make use of the available spectrum, thereby accommodating higher rate users requiring greater bandwidths and time slot assignments while still preserving cost-efficient access for lower speed users. Depending on the signal modulation scheme, the time-frequency slices may be allocated on non-contiguous frequency bands. The system and method is also applicable to code-division multiple access (CDMA) techniques by slicing the available code space along time-code domains, frequency-code domains or, in three dimensions, along time-frequency-code domains. Users may be efficiently scheduled based on code space requirements so as to optimize use of the communication medium.

摘要： A multi-code code division multiple access system allows a user at a radio transmitter unit to dynamically change its source data bit rate. In response to a user input selecting one of the plurality of source bit rates, an adjustable coding circuit in the transmitter spreads and transmits the user's digital bit stream received at the selected bit rate to a channel bit rate which at least equals the highest bit rate of the plurality of source bit rates. The plurality of source bit rates includes a basic bit rate R and at least one bit rate which is a multiple M of the basic bit rate R, where M is an integer of at least 1. The user's input selects a particular user source bit rate by identifying a basic bit rate multiple M to a base station that is to receive the transmission.

摘要： Signal distortion in fiber optic systems is compensated for by forming decisions as to the transmitted information as a joint function of the received signal and of a feedback signal. The latter, in turn, is a function of decisions made for at least one signal transmitted over the fiber. The feedback signal determines the value of a threshold to which the received signal is compared in order to generate the decisions.
