A message sending method and device

Abstract

Embodiments of the present invention provide a method and device for sending a message. The method for sending a message includes: receiving a message to be sent; determining the DR identifier of the DR port that sends the message to be sent, and identifying the state of the DR port; if the If the status of the DR port is DOWN, the network ID corresponding to the DR ID of the DR port is encapsulated in the message to be sent, and the message to be sent with the network ID encapsulated is forwarded to the neighbor DR device, so that the neighbor DR device Based on the network identifier, the message to be sent is sent from the DR port with the DR ID corresponding to the network identifier; if the state of the DR port is UP, the message to be sent is sent from the DR port. Through this solution, the efficiency of message sending 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...

Problems solved by technology

[0004] However, as the DRNI network model continues to expand and the number of terminals and DR devices in the network continues to increase, each DR device needs to store an increasingly large forwarding table, and each DR device needs to forward packets to the forwarding table. Query during publication, the larger the forwarding table, the slower the query speed, resulting in lower message sending efficiency
