Abstract: A virtual network (VN) realization method and system are provided. The method includes setting a VN-AP in a data center network and/or a broadband network. A service deployment and management function entity receives a VN service request from a user to generate feature information of the VN; a PC/VM automatically discovers the VN-AP, the automatically discovered VN-AP generates the VN forwarding table entry of the PC/VM after the PC/VM passes the identity authentication of the VN, and performs tunnel encapsulation according to the VN forwarding table entry to forward a packet from the PC/VM. By discovering a VN-AP for processing a VN automatically, the disclosure realizes the automatic and rapid deployment of the VN.

Abstract: Disclosed are methods and systems for accessing a Virtual Network (VN). The method includes: a Broadband Network-Network Virtualization Edge (BN-NVE) accepts access of a broadband user terminal to a VN in a data centre, and generates a forwarding table about the VN and its corresponding table entry; the BN-NVE performs interaction with an NVE of the VN to be accessed with respect to information of the forwarding table to synchronize information of the forwarding table of the VN; and the BN-NVE searches the forwarding table about the VN according to a destination address of a message of the broadband user terminal, forwards the message after tunnel encapsulation to a destination NVE in the VN, and forwards the message to a destination Virtual Machine (VM) through the destination NVE to implement VN access of the broadband user terminal. Another method includes: a VN service development and management entity in a data centre accepts an access request of a broadband user terminal for a VN in the data centre, and selects an NVE of the VN as an access NVE of the VN; and the access NVE of the VN establishes a security tunnel with the broadband user terminal, and implements VN access of the broadband user terminal through the established security tunnel. By the disclosure, the problem that a data centre gateway becomes a bottleneck when an Internet user accesses the VN in the data centre is solved.
