CA 2158013
The present application concerns a method and an apparatus, e.g. in a Token-Ring adapter of a communication network, for processing the various fields of a protocol header preceding a data stream to provide a unique connection identifier for processing said data stream. All relevant protocol information is extracted from said protocol header for looking up in a Content-Addressable Memory (80). Each time an entry in said CAM (80) matches protocol information applied to the CAM's input (84), the CAM address of this storage section, i.e. the address of a row of said CAM (80), is provided at the output (82) thereof. The CAM addresses obtained from said protocol header are concatenated by means of a Connection Number Builder (CNB, 95) resulting in a unique connection identifier provided at the Protocol Filter's output (96) to be used for the processing of said data stream.
