METHOD AND APPARATUS FOR FORWARDING TRAFFIC OF SWITCHING SYSTEM

摘要

Embodiments of the present invention provide a method and an apparatus for forwarding traffic of a switching system. The switching system includes a first LCC, at least one second LCC, and at least one third LCC that are interconnected according to a mesh form topology; and the method includes: receiving, by the first LCC, a packet, and parsing the packet to acquire a destination address of the packet; and when the destination address indicates that the packet is to be sent to the third LCC, if a currently preset configuration mode of the switching system is a first configuration mode, bearing, by the first LCC, the packet on a third link, and forwarding the packet to the third LCC, where the first configuration mode indicates that an N-hop mode is currently applied to the switching system, where N is a natural number greater than or equal to 3.

1. A method for forwarding traffic of a switching system, wherein the switching system comprises a first line card chassis LCC, at least one second LCC, and at least one third LCC that are interconnected according to a wireless mesh form topology; and the method comprises:
receiving, by the first LCC, a packet, and parsing the packet to acquire a destination address of the packet; and when the destination address indicates that the packet is to be sent to the third LCC, if a currently preset configuration mode of the switching system is a first configuration mode, bearing, by the first LCC, the packet on a third link, and forwarding the packet to the third LCC, wherein the third link comprises: a first link and a second link, or a second link; the first link is a directly connected two-hop link between the first LCC and the third LCC, and a quantity of links comprised by the first link is at least one; the second link is an n-hop link that passes through the at least one second LCC and that is between the first LCC and the third LCC, and a quantity of links comprised by the second link is at least one, wherein n is a natural number, and 3≦n≦N; and the first configuration mode indicates that an N-hop mode is currently applied to the switching system, wherein N is a natural number greater than or equal to 3.
