Patent

CA 2420310

The invention relates to the protocol processing in a network element. The idea of the invention is to divide an IP protocol stack between a CPU and several DSP's in a network element. Because the CPU contains a MAC-interface for an Internet interface and it routes IP traffic to the right DSP, a certain part of the IP protocol stack must be handled in the CPU. Each DSP handles the rest of the IP protocol.

L'invention concerne le traitement de protocoles dans un élément de réseau. L'idée de l'invention consiste à diviser une pile de protocoles IP entre une UCT et plusieurs DSP (processeurs de signaux numériques) d'un élément de réseau. Comme l'UCT contient une interface MAC (contrôle d'accès au support) pour interface Internet et qu'elle achemine le trafic IP vers le DSP adéquat, une certaine partie de la pile de protocoles IP doit être traitée par l'UCT. Chaque DSP traite le reste du protocole IP.
