Patent ID: 7551575

Claim:
A stream parser for parsing incoming network data traffic, comprising: an input for receiving a time division multiplexed (TDM) multi-channel data stream; a context switch module to selectively store a first portion of the received TDM multi-channel data stream when an incoming second portion from the input is from a different channel than the first portion, wherein the first portion is being stored to be combined with a subsequently received third portion of the received TDM multi-channel data stream, wherein the first portion and the subsequently received third portion belong to the same channel; a logic unit in communication with said input and said context switch module for performing at least one of parsing and altering the received TDM multi-channel data stream, wherein said logic unit performs at least one of parsing and altering on the combined first and third portions; and an output for transmitting the TDM multi-channel data stream.
