Abstract

The invention provides a message transmission method and device. The method is applied to a network device which comprises a forwarding chip and a processor. The method comprises the steps of, by the forwarding chip, receiving a message, sending the message to the processor when the message is succeeded in matching an inner-layer fast forwarding table item and failed in matching an outer-layer fast forwarding table item, and indicating that the message is the message which is succeeded in matching an inner-layer fast forwarding table item and failed in matching an outer-layer fast forwarding table item for the processor; and when the message is received by the processor and if the message is determined to be the message which is succeeded in matching an inner-layer fast forwarding table item and failed in matching an outer-layer fast forwarding table item, sending the message through a routing table. By applying the embodiment, the forwarding chip can indicate that the message is the message which is succeeded in matching an inner-layer fast forwarding table item and failed in matching an outer-layer fast forwarding table item for the processor, accordingly normal service transmission can be guaranteed, and service interruption can be avoided.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a method and device for message transmission. Background technique [0002] The fast-forwarding entry is a forwarding entry used by network equipment to improve packet forwarding performance, and the fast-forwarding entry is applied in the forwarding chip. For encapsulation services, the fast-forwarding entries include inner-layer fast-forwarding entries and outer-layer fast-forwarding entries. After receiving the message, the forwarding chip of the network device first searches for the inner-layer fast-forwarding entry and encapsulates the message. After that, look for the outer fast-forwarding entry and forward the encapsulated message. However, if the outer fast-forwarding entry is abnormal, the forwarding chip will send the encapsulated message to the processor of the network device. The processor checks the validity of the encapsulated message. S...
