Abstract

The invention discloses a message forwarding method of VSDs (virtual switch devices) in a VSU (virtual switch unit) and member devices of the VSU. Stack links are arranged among interface boards distributed on different member devices of at least one VSD in the VSU, after the interface boards connected with the stack links receive unicast messages of the interface boards disconnected from the stack links and belonging to different VSDs from the same member device, the unicast messages are transmitted by the stack links when the destination addresses of the unicast messages are the interface boards disconnected from the stack links and belonging to the different VSDs in another member device, and after the interface boards connected with the stack links receive the unicast messages through the stack links, the unicast messages are transmitted according to the destination addresses of the unicast messages when the destination addresses of the unicast messages are the interface boards disconnected from the stack links and belonging to the different VSDs in the same member device.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a message forwarding method of a virtual switching device (VSD, Virtual Switching device) in a virtual switching unit (VSU, Virtual Switching Unit) and a member device of the VSU. Background technique [0002] VSU is a network system virtualization technology that supports combining multiple devices into a single logical device, that is, several physical member devices are equivalent to a virtual logical device, and the connection between member devices is called a stack link (VSL ). Such as figure 1 As shown, member device 1 and member device 2 can form a virtual device through stack links, that is, a VSU system. [0003] VSD is another virtual technology that virtualizes a physical device (such as a switch) into multiple logical devices. Each logical device is called a VSD. Each VSD is an independent device for users and has its own independent operation. The routin...
