Network private line establishment method, apparatus and system

Abstract

Embodiments of the present invention provide a network private line establishment method, apparatus and system, relating to the technical field of network communication. The network private line establishment method is low in operation complexity and comprises the steps of when a network private line service of a target client is opened, receiving first policy information; acquiring an IP address of virtual customer premise equipment (vCPE) meeting demand information of a network private line of the target client; receiving a request message for connection establishment that is sent by any request CPE of the at least two CPEs; and acquiring, according to the request message for connection establishment, an identifier of the first vCPE and configuration of a first virtual extensible local area network (VxLAN), sending the identifier of the first vCPE to the vCPE corresponding to each peer CPE, and sending the configuration of the first VxLAN to the request CPE and the first vCPE, so as to realize point-to-point communication of the network private line of the target client finally.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of network communication, and in particular, to a method, device and system for establishing a dedicated network line. Background technique [0002] A private network (for example, Point to Point Protocol over Ethernet, PPPoE) private line refers to the establishment of a private network in a public network, and data is transmitted in the public network through a secure "encrypted channel". Enterprises and local institutions) only need to rent local network dedicated lines and connect to the local Internet (Internet), and network dedicated line users in various places can transfer information to each other. [0003] In the prior art, usually through VLAN (Virtual Local Area Network, Virtual Local Area Network), realize the networking of network leased line, usually, after the user who needs to set up network leased line puts forward the application of opening network leased line to ...

[0003] In the prior art, usually through VLAN (Virtual Local Area Network, Virtual Local Area Network), realize the networking of network leased line, usually, after the user who needs to set up network leased line puts forward the application of opening network leased line to network operator, network operator goes to the scene according to The user who needs to establish a network leased line needs to request information to open the service, and realize the point-to-point leased line connection through VLAN. The VLAN uses a Layer 2 VPN, and the Layer 2 transmission channel is based on the MAC address. However, the access network There are many kinds of IP networks. If the transmission is based on VLAN, it mainly uses the Layer 2 network. It needs to do a lot of static routing configuration or directly establish a Layer 2 dedicated line. It will be more complicated when it involves cross-regional cities. However, the CPE gateway is mainly managed by the ACS (Automatic Configuration Server, automatic configurati
