Embodiment Construction

[0031] refer to Figure 4 , establish a virtual interface between the VS and the IP forwarding component. The virtual interface has the same function as the general Ethernet interface, except that the general Ethernet interface processes data from external physical ports, while the "virtual interface" processes data from the internal data exchange chip of the device.

[0032] A virtual interface is a software module. The design of the virtual interface is consistent with that of the general Ethernet interface. The main difference between a virtual interface and a general Ethernet interface is that a general Ethernet interface processes frames in Ethernet format received from a physical Ethernet port. The virtual interface processes the data frames received from the data exchange hardware unit inside the device, and the format of these data frames is defined inside the device, such as a fixed-length cell format. The Ethernet message sent through the internal data channel is ...

Abstract

The method includes steps: (1) building virtual interface between virtual exchanger and IP forwarding module; (2) virtual interface processes data from users at virtual interface side, and processed data through IP forwarding module to send to IP public network; (3) virtual interface processes data from IP public network forwarded by IP forwarding module; and the processed data through virtual exchanger to send to users at virtual exchanger side. The invention expands service range of exchanger system, reduces port resources of device engaged by VPLS user when the VPLS user accesses public network. Benefits are: increasing earnings means of operation company, and difficulties of building VPLS through VS.

Description

technical field [0001] The invention generally relates to network communication technology, in particular to a method for connecting a virtual switch system to an IP public network. technical background [0002] A virtual switch (VS) is an implementation method of a virtual private network (VPN). A virtual switch is a functional entity generated through configuration on a network device, and it can complete the function of an Ethernet switch. A network device can be divided into multiple virtual switches, and the virtual switches can be used to form a virtual private local area network segment (VPLS) and provide user traffic aggregation. [0003] The virtual switch is initially applied to ATM (Asynchronous Transfer Mode) equipment to provide virtual private local area network segment services. Afterwards, the virtual switch added Ethernet access and GRE (General Routing Encapsulation) tunnel access functions for transparently transmitting Ethernet packets on the IP public ...
