A method and apparatus for reducing the amount of corrupted data in a system for transmitting encoded data across a network, which system requires sychronization between encoding and decoding nodes, the method and apparatus involving (a) providing an indication of the reliability of the channel between the encoding and decoding nodes; (b) performing automatic resets at the nodes at intervals I; and (c) utilizing the indication of channel reliability to control the interval I. The interval I may be determined, for example, by the error rate on the channel for one or more preceding time interval S, and may be determined at either the encoding or decoding node.

A single queue or descriptor ring references several context control blocks, each of which corresponds to a different data path in a communications system. An entry in the descriptor ring references an appropriate context control block and a source packet representing a packet locations prior to processing. The descriptor ring may include a destination packet representing the packet locations after processing. The descriptor ring is particularly suitable for communications between a main processor and a coprocessor.

A system for transmitting compressed data for multiple channels or contexts from a single node which system reduces memory utilization without significant adverse effect on compression ratio by providing a separate history buffer for each channel, with a single hash table being provided for generating potential match addresses in the history buffer for at least selected ones of the channels. A single chain table may also be provided, the chain table having a single offset address for the corresponding offset addresses in the buffers for the selected channels. Collisions in the common hash table may be reduced by including channel address or the like as an additional input to the hash table, thereby biasing the address outputs therefrom.
