Active/standby switchover method, device, equipment and system for network equipment

Abstract

An active and standby changeover method, apparatus, device, and system for a network device relate to the technical field of wireless networks. The method comprises: receiving an interrupt signal indicating that a changeover needs to be performed for active and standby GE ports; performing a switching operation of the active and standby GE ports, setting the active GE port to a blocked state, and in the blocked state, the active GE port only forwarding a bridge protocol data unit (BPDU) packet, and stopping learning a MAC address; and enabling the standby GE port, setting the standby GE port to a forwarding state, and in the forwarding state, the standby GE port forwarding packets of all types, and learning the MAC address. By using the foregoing method, rapid completion of active and standby GE ports can be implemented, and a requirement of hand-in-hand double chain protection of an electric power EPON standard is met.

Description

technical field [0001] The present invention relates to the field of wireless networks, in particular to a method, device, device and system for active / standby switchover of network equipment. Background technique [0002] With the maturity of optical access network technology, optical fiber will replace copper wire as the mainstream access method. Such as figure 1 As shown, there is an ONU (Optical Network Unit) in a general residential corridor, which is connected to an OLT (Optical Access Terminal) in the upstream direction through a PON port, and one OLT is responsible for data transmission of multiple ONUs. Among them, the GE port in the ONU divides the data and sends it to the users in the corridor through the FE port (100M port) (such as figure 1 PC in ). [0003] In order to meet the disaster recovery requirements of the network system, the optical node ONU is equipped with a master GE port and a backup GE port. When the master GE port fails, the ONU performs the ...

AI Technical Summary

Problems solved by technology

[0004] 1. As the number of ONU ports increases, the isolation time between the set ports becomes longer, so the switching time will also be extended, making it difficult to meet the requirements of fast switching

[0005] 2. In the existing isolation method, the CPU in the ONU is not isolated from the standby GE port (such as figure 1 ), the incoming packets from the CPU (such as ping packets) will be sent to all GE ports, and the active and standby PON ports will also send the same two packets, so it cannot meet the hand-in-hand dual-chain protection requirements of the power EPON standard. For details, see attached figure 2
