Method, apparatus and system for virtual network configuration and partition handover
First Claim
1. A dynamic virtual network configuration method, comprising:
- by a serving edge device, in the process of a user handover from a current virtual network to a target virtual network, obtaining a target virtual network identifier and a corresponding interface identifier, using the target virtual network identifier and the corresponding interface identifier of the interface accessed by the user, to generate a Layer-2 Control (L2C) protocol packet, and sending out the L2C protocol packet; and
by a communication proxy device that receives the L2C protocol packet, obtaining the target virtual network identifier and the corresponding interface identifier from the L2C protocol packet, and setting up a mapping relation between a target virtual network and an interface;
wherein the process of setting up the mapping relation between the target virtual network and the interface comprises;
by the communication proxy device, dynamically deleting a physical interface identifier corresponding to the interface identifier from a physical interface partition list corresponding to a current virtual network identifier; and
adding the physical interface identifier to a physical interface partition list corresponding to the target virtual network identifier;
orby the communication proxy device, dynamically deleting a virtual interface identifier corresponding to the interface identifier from a virtual interface partition list corresponding to a current virtual network identifier; and
adding the physical interface to a physical interface partition corresponding to the target virtual network identifier.

Abstract
A method, apparatus and system for virtual network configuration and partition handover are provided. The virtual network configuration method includes the following steps: The serving edge device obtains a target virtual network identifier and a corresponding interface identifier, uses the target virtual network identifier and the corresponding interface identifier to generate a Layer-2 Control (L2C) protocol packet, and sends out the L2C protocol packet; the communication proxy device that receives the L2C protocol packet obtains the target virtual network identifier and the corresponding interface identifier from the L2C protocol packet, and sets up a mapping relation between a target virtual network and an interface.
