Abstract

The invention provides a method and a device for synchronizing an address resolution protocol (ARP) table item. The method comprises the steps that an initiating device receives a message of the ARP table item and determines to perform message modification on the message of the ARP table item to acquire a first ARP real-time synchronization message; and the initiating device sends the first ARP real-time synchronization message to a transferring device, wherein the transferring device performs message modification on the first ARP real-time synchronization message to acquire a second ARP real-time synchronization message, the transferring device sends the second ARP real-time synchronization message to other initiating devices or other transferring devices and informs the initiating devices or the transferring devices to perform message parsing processing on the second ARP real-time synchronization message, thereby solving a problem that the ARP table item cannot be synchronized in real time between devices in cluster deployment networking, and realizing real-time synchronization of the ARP table item between devices in cluster deployment networking.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for synchronizing address resolution protocol (ARP) entries. Background technique [0002] In the context of the big data era, there are more and more networks that increase bandwidth by deploying devices in clusters. In order to increase the traffic switching rate and improve the reliability and stability of the cluster system, it is necessary to share the Address Resolution Protocol (Address Resolution Protocol, referred to as For ARP) entries, do a real-time backup. [0003] In related technologies, the synchronization of existing ARP entry information is either carried in the virtual router redundancy protocol (Virtual Router Redundancy Protocol, referred to as VRRP) backup group, or through the network management, and there are ARP entries between devices in the cluster deployment network real-time synchronization issues. [0004] In related technologies, th...
