Embodiment Construction

[0077] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0078] A method for accessing a virtual network provided by an embodiment of the present invention, such as figure 2 As shown, it mainly includes the following steps:

[0079] Step 201, the network virtualization edge node (BN-NVE) in the broadband network accepts the access of the broadband user terminal to the VN in the data center, generates the forwarding table of the VN, and forms the corresponding broadband node in the forwarding table. The forwarding entry of the user terminal.

[0080] Set NVE in the bandwidth network to accept the VN access of broadband user terminals.

[0081] After the broadband user terminal accesses the broadband network, the broadband user terminal first needs to pass the broadband access authentication of the broadband network, and obtains the IP address assigned to the broadband us...

Abstract

The invention discloses a virtual network (VN) access method and system. The method comprises the following steps: BN-NVE accepts access of VN in a data center by a wide-band subscriber terminal and generates a forwarding table of the VN and corresponding table items; the BN-NVE is in forwarding table information interaction with the NVE (Network Virtualization Edge) of the accessed VN to form the information synchronization of the VN forwarding table; looking up the VN forwarding table by the BN-NVE according to the destination address of the massage of the wide-band subscriber terminal, transmitting the message to a destination NVE in the VN after the massage is encapsulated through a tunnel, and then transmitting the message to a destination VM through the destination NVE, so that the NV access of the wide-band subscriber terminal is completed. Another method comprises the following steps: a VN business development and management entity in the data center accepts an access request of the wide-band subscriber terminal on the VN in the data center and selects one NVE of the VN as the accessed NVE of the VN; a security tunnel is established between the accessed NVE of the VN and the wide-band subscriber terminal, and the VN access of the wide-band subscriber terminal is completed through the security tunnel. The method solves the problem that the gateway of the data center becomes a bottleneck because an internet user accesses the VN in the data center.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a virtual network access method and system. Background technique [0002] NVO3 (L2″Network Virtualization Over L3″overlay, layer 2 network virtualization based on layer 3 overlay network, referred to as layer 3 based network virtualization) research group is IETF (Internet Engineering Task Force, Internet Engineering Task Force) for data center Research group that provides multi-tenant networking. The NVO3 research group is working on network virtualization technology based on overlay network to realize multi-tenant network in data center. Such as figure 1 As shown, it is a schematic diagram of the data center network structure of NVO3. There is a data center gateway in the network structure, and the data center gateway is used to realize the connection of Internet (INTERNET) users to the VN (Virtual Network, virtual network) in the data center. However, there is...
