Message sending method and device

Abstract

The embodiment of the invention provides a message sending method and device. The method comprises the steps of: receiving a message to be sent; determining a DR (Distributed Relay) identifier of a DRport used to sent the message to be sent, and identifying the state of the DR port; if the state of the DR port is a DOWN state, packaging a network identifier corresponding to the DR identifier of the DR port in the message to be sent, and forwarding the message to be sent with the packaged network identifier to an adjacent DR device to allow the adjacent DR device to sent the message to be sentfrom the DR port having the DR identifier corresponding to the network identifier based on the network identifier; and if the state of the DR port is a UP state, sending the message to be sent from the DR port. According to the scheme, the message sending efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message sending method and device. Background technique [0002] DRNI (Distributed Resilient Network Interconnect) is a cross-device link aggregation technology that virtualizes two network devices into one device at the aggregation level to achieve cross-device link aggregation, thereby providing device-level redundancy Protection and traffic load sharing. Such as figure 1 In the DRNI network model shown, DR (Distributed Relay, distributed aggregation) device 1 and DR device 2 form load sharing, and the two DR devices are neighbors to each other. When one of the DR devices fails, packets can be quickly switched to Another DR device ensures normal sending of packets. [0003] The specific process of message sending is: two DR devices share the same forwarding table, one of the DR devices receives the message sent by the sender, and the message carries the send...
