DISTRIBUTED VIRTUAL SWITCH SYSTEM

摘要

A distributed virtual switch system comprises a controller and multiple servers. Each server is configured with a virtual SDN switch and at least one VM. Each VM is connected with an external physical switch via the SDN switch. The controller obtains interface information of a switch logic interface corresponding to a VM, adds an entry comprising the interface information into a local global interface management table. The interface information includes a global unique identifier of the switch logic interface corresponding to the VM, a switch identifier of an SDN switch corresponding to the switch logic interface, and a local port identifier of the SDN switch corresponding to the switch logic interface. The controller manages each VM connected with each SDN switch according to the local global interface management table.
