System and method for load-sharing computer network switch
First Claim
1. A switch system communicatively connected with a computer network, the switch system comprising:
- a line card comprising a plurality of ports each operable to provide communicative connections with a network device;
a set of active switch fabric cards comprising a first and second switch fabric card to provide switching functionality between the computer network and the line card, wherein the first and second switch fabric card are operable to concurrently carry network traffic; and
a first system control card to provide control functionality for the line card.

Abstract
A computer network switch system is disclosed. A switch system may be configured as a single chassis system that has at least one line card, a set of active switch fabric cards to concurrently carry network traffic; and a first system control card to provide control functionality for the line card. The switch system may be configured as a multiple chassis system that has at least one line card chassis containing several line cards, and a switch fabric chassis (or a second line card chassis) that contains several switch fabric cards to provide a switching fabric with multiple ports. Load-sharing is accomplished primarily at the chip level, although card-level load-sharing is possible.
