Abstract: In a forwarding fault location determining method, a controller receives a plurality of table search statistical results of a plurality of forwarding tables for a first service from one or more forwarders. The plurality of forwarding tables include a first forwarding table and a second forwarding table, and the first forwarding table is prior to the second forwarding table in terms of a search sequence. Subsequently, the controller determines that table search behavior of the first forwarding table for the first service is normal and table search behavior of the second forwarding table for the first service is abnormal. The controller determines, based on the determining result, that the second forwarding table is a faulty forwarding table for the first service.

Abstract: According to a method, when it is detected that service traffic needs to be switched from a first optical layer path to a second optical layer path, a first internet protocol (IP) link associated with the service traffic needs to be determined, and an IP link used to transmit the service traffic is adjusted from the first IP link to a second IP link; an optical layer path of the first IP link is switched from the first optical layer path to the second optical layer path after the adjustment of the IP link is completed; and the IP link used to transmit the service traffic is adjusted from the second IP link to the first IP link after the switching of the optical layer path is completed. In this way, continuity of the service traffic can be ensured.
