Abstract
A real-time load-balancing system for distributing a sequence of incoming data packets emanating from a high speed communication line to a plurality of processing means, each operating at a capacity that is lower than the capacity of the high speed communication line; the system according to the invention comprises: a parser capable of extracting a configurable set of classifier bits from the incoming packets for feeding into a compression means; the compression means is capable of reducing a bit pattern of length K to a bit pattern having a length L which is a fraction of K; a pipeline block for delaying incoming packets until a load balancing decision is found, and an inverse demultiplexer for receiving a port identifier output from said compression means as selector and for directing pipelined packets to the appropriate output port.
