Method of version upgrade of network device and network device

Abstract

Embodiments of the invention disclose a method of a version upgrade of a network device and a network device relating to the field of communications. The method of the version upgrade of the network device and the network device resolve a technical question that network congestions are caused by overmuch occupations of network bandwidths caused by forwards of a large number of broadcast messages during the version upgrade of the network device. The concrete proposals are that: forwarding planes of the network device are configured into a first forwarding plane and a second forwarding plane, forwarding messages are sampled on the first forwarding plane by a preset sampling proportion to acquire sampling messages, and the sampling messages are performed broadcast forwards by the second forwarding plane to learn MAC addresses. When the amount of learned MAC addresses by the second forwarding plane achieves a preset threshold, the broadcast forwards of the network device of the second forwarding plane is upgraded. The technical proposals provided by the embodiments of the invention can effectively avoid generations of a large number of the broadcast messages during the course of the version upgrade, be capable of reducing the overmuch occupations of the network bandwidths, and avoid the network congestions.

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, and the message will be broadcast when the MAC address entry cannot be matched. Send and ...
