Abstract

The invention discloses a message forwarding method and device in a virtual switching unit (VSU) system and network equipment. According to the method, a single-cast route between any member equipment serving as inlet equipment and another member equipment serving as outlet equipment is set to be coincident with a multicast route; and when forwarding equipment forwards a single-cast message according to the multicast route, the message can be correctly forwarded, and the forwarded single-cast message cannot be lost in the VSU system; therefore, the problem that the single-cast message is lost because the forwarding equipment in the VSU system forwards the single-cast message according to the multicast route in the prior art can be solved.

Description

Technical field [0001] The present invention relates to a network communication system, in particular to a method and device for message forwarding inside a virtual switching unit (VSU, Virtual Switching Unit) system, and network equipment. Background technique [0002] VSU is a network system virtualization technology that supports the combination of multiple devices into a single virtual device. The user manages the virtual device and can manage all the devices in the VSU. According to different functions, member devices are divided into two roles: main device and backup device. The main device is a type of member device and is elected by the role. It is responsible for managing the entire VSU. Only one member device in a VSU can become a member device at a time. Main equipment; backup equipment is also a kind of member equipment. It belongs to the main equipment and runs as the backup equipment of the main equipment. In the VSU system, except for the main equipment, other equ...
