Method for upgrading network device version and network device

Abstract

The embodiment of the invention discloses a method and device for upgrading a version of a network device, relates to the field of communication, and solves the technical problem that a large number of broadcast messages need to be sent during the version upgrading of a network device, resulting in excessive occupation of network bandwidth and network congestion. The specific solution is: configure the forwarding plane of the network device as a first forwarding plane and a second forwarding plane, and sample the forwarded message on the first forwarding plane with a preset sampling ratio to obtain the sampled message The second forwarding plane broadcasts and forwards the sampled message to learn a MAC address, and when the number of MAC addresses learned by the second forwarding plane reaches a preset threshold, upgrades the second forwarding plane for the Packet forwarding of network devices. The technical solution provided by the embodiment of the present invention can effectively avoid generating a large number of broadcast messages during the version upgrade process, and can help reduce excessive occupation of network bandwidth and avoid network congestion.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for upgrading the version of network equipment and network equipment. Background technique [0002] The hardware and software of network devices are complex, and there is a large demand for version replacement or upgrade, because the service interruption time caused by version change and upgrade is also included in the mean time to recovery (MTTR) of the device, so How to reduce the service interruption time during version upgrade is a problem that every equipment manufacturer needs to solve. In-Service Software Upgrade (ISSU for short) and zero packet loss have always been the goals pursued by operators and equipment manufacturers. [0003] In the process of forwarding the Layer 2 message, the message forwarding is based on the matching of the Media Access Control (MAC) address entry. When the MAC address entry cannot be matched, the message will be broadcast and sent. , a...
