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 message forwarding method and device in a Virtual Switching Unit (VSU, Virtual Switching Unit) system, and a network device. Background technique [0002] VSU is a network system virtualization technology that supports combining multiple devices into a single virtual device. Users can manage virtual devices and manage all devices in the VSU. According to different functions, member devices are divided into two roles: master device and backup device; the master device is a kind of member device, which is elected by the role and is responsible for managing the entire VSU. Only one member device in a VSU can be a member device at a time. Master device; backup device is also a kind of member device, which belongs to the master device and operates as the backup device of the master device. In the VSU system, except the master device, other devices are backup devices. [00...
