Claim Text:
1. A cell processing method for a Switch Fabric SF chip, comprising: providing, in the SF chip, a unicast route table, which is multiplexed in two working modes of an SF13 mode and an SF2 mode and is looked up according to a unicast cell; providing, in the SF chip, a multicast route table, which is multiplexed in the two working modes of the SF13 mode and the SF2 mode and is looked up according to a multicast cell; receiving, by the SF chip, a cell and an input link number corresponding to the cell from an upstream apparatus, and extracting a destination Identifier ID of the cell; looking up, by the SF chip, a route table according to a working mode of the SF chip, the destination ID and the input link number, and determining a first bitmap corresponding to the cell; and performing, by the SF chip, load balancing on the first bitmap to obtain a second bitmap, and outputting the cell to a downstream apparatus according to the second bitmap.
