Abstract
A cell processing method and device for a Switch Fabric (SF) chip are disclosed, which belong to the field of communications. The SF chip includes a unicast route table, which is multiplexed in two working modes and is looked up according to a unicast cell, and a multicast route table, which is multiplexed in the two working modes and is looked up according to a multicast cell. The cell processing method for an SF chip includes: the SF chip receives a cell and an input link number corresponding to the cell from an upstream apparatus and extracts a destination Identifier (ID) of the cell; the SF chip looks up a route table according to a working mode of the SF chip, the destination ID and the input link number to determine a first bitmap corresponding to the cell; and the SF chip performs load balancing on the first bitmap to obtain a second bitmap and outputs the cell to a downstream apparatus according to the second bitmap. With the technical solutions of the disclosure, the SF chip in a cascade switching system can adapt to different working modes.
