Pon system and method for uninterrupted lacp aggregation link during active/standby switching

Abstract

The invention discloses a PON system and a method for uninterrupted LACP aggregation links in active-standby switching, and relates to the field of communication technology, wherein the PON system includes a main system control unit, a backup system control unit and an uplink disk, and the main system control unit Both the main system control unit and the backup system control unit are connected to the uplink disk, and the main system control unit and the peer device send and receive LACP protocol packets through the uplink disk, and the LACP protocol packets sent by the main system control unit and the backup system control unit The system IDs in this document are the same, and the physical state of the uplink port on the standby system control unit is UP. The invention can ensure that the LACP aggregation link is not interrupted before and after the active-standby switchover, and ensures that user services are not affected by the active-standby switchover.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a PON system and method for uninterrupted LACP aggregation links during active / standby switching. Background technique [0002] Link aggregation (Link Aggregation) is a technology that bundles multiple physical ports into one logical port. This technology can treat multiple physical connections as a single logical connection, allowing two network devices to be connected in parallel through multiple ports and transmit data at the same time to provide higher bandwidth and throughput and improve system stability . According to whether member ports run LACP (Link Aggregation Control Protocol, Link Aggregation Control Protocol) protocol, link aggregation can be divided into two modes: static aggregation and dynamic aggregation. [0003] The LACP protocol is a protocol that realizes dynamic link aggregation. The LACP protocol exchanges information with the peer end through LAC...

Problems solved by technology

However, since the MAC addresses of the master disk and the slave disk are different, the MAC address used by the system to send packets changes before and after the master and slave switchover. The LACP protocol needs to be re-negotiated with the peer device, which will cause the LACP aggregation chain to be interrupted for a few seconds. Thus affecting the user's Internet access, voice and data services
