Abstract: A cell processing method and apparatus are provided. The method includes: obtaining, by a first sending end, a first timestamp compensation time; adding, by the first sending end, the first timestamp compensation time to a first timestamp carried in a first cell, where the first timestamp is a sending time of the first cell; and sending, by the first sending end to a receiving end, the first cell that is added with the first timestamp compensation time, so that the receiving end forwards the first cell according to the first timestamp that is added with the first timestamp compensation time. In the present invention, a first timestamp compensation time is added to a first timestamp carried in a first cell, which improves cell forwarding efficiency of the receiving end and prevents the occurrence of cell accumulation in a link.

Abstract: 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.

Abstract: A buffer module includes N queues configured to buffer M data streams, where N is less than M. A counting module includes M counters, the M counters are in a one-to-one correspondence with the M data streams, and the M counters are configured to count buffer quantities for the M data streams in the N queues. The control module is configured to, when a count value on a first counter exceeds a corresponding threshold, discard a to-be-enqueued data packet of a data stream corresponding to the first counter, or control the sending module to send pause indication information to an upper-level control module.
