Michael G Hluchyj, Nanying Yin: Dynamic encoding rate control minimizes traffic congestion in a packet network. Codex Corporation, Darleen J Stockley, Charles L Warren, May 19, 1992: US05115429 (217 worldwide citation)

This invention is suited for a packet network that carries bursty data. A mechanism is coupled to an edge node for coding bursty information into a digital format at either a first coding rate of a second coding rate which is less than the first rate. A mechanism senses traffic overload of one or mo ...

Michael G Hluchyj, Amit Bhargava: Device and method for implementing queueing disciplines at high speeds. Codex Corporation, Darleen J Stockley, December 7, 1993: US05268900 (168 worldwide citation)

A device (800) and method (900) are included for providing a high-rate queueing discipline in an information network system having a plurality of traffic classes. The high-rate queueing discipline is based on a scan table-based dequeueing scheme having a scan table that is precomputed and stored in ...

Forney Jr George David: Sequential decoding. Codex Corporation, May 23, 1972: US3665396 (116 worldwide citation)

An improved error-correcting decoder for convolutional codes, of the sequential decoding type, is described. By restriction of received digit quantization to hard decisions, the number of alternatives in a single decoding search move is made sufficiently small that an entire move can be completed in ...
