Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] Before describing the embodiment of the present invention in detail, first introduce the networking environment of the embodiment of the present invention. The networking environment of the embodiment of the present invention takes an MPLS network as an example. The network includes 4 network elements, namely network element PE1, network NE PE2, NE P3, and NE P4, and seven bidirectional tunnels have been pre-configured, such as Figure 6 As shown, they are:

[0048] Tunnel-12-1: The starting point network element is PE1, the end point network element is PE2, and data exchange is performed at network element P3; the tunnel type is L-LSP (label switched path derived from labels); CoS (Class of Service, service level ) type is BE ...

Abstract

The embodiment of the invention discloses a method and a device for establishing pseudo wires, which belong to the field of network management. The method comprises the following steps: acquiring pseudo wire basic configuration information comprising pseudo wire starting points, end points and service quality parameters; according to the pseudo wire starting points and end points, acquiring tunnel resources; according to the pseudo wire service quality parameters, acquiring a pseudo wire carrying tunnel from the tunnel resources; and transmitting the pseudo wire basic configuration information and a tunnel mark to a network element to be provided with the pseudo wires. The device comprises a first acquisition module, a second acquisition module, a third acquisition module and a transmission module. The technical scheme provided by the embodiment of the invention overcomes the disadvantages of artificial station-by-station pseudo wire configuration and pseudo wire configuration in a signaling mode.

Description

technical field [0001] The invention relates to the field of network management, in particular to a method and device for creating a pseudowire. Background technique [0002] Pseudo Wire Emulation Edge to Edge (PWE3) is developed by Internet Engineering Task Force (IETF) to simulate end-to-end services on Packet Switched Network (PSN). technical standard. PWE3 uses common labels to provide operators with a unified multi-service delivery platform, so that different services can be converged to PSN in a unified way, thereby reducing the number of networks, configuration and maintenance complexity, and link costs. PWE3 can not only flexibly support new services, but also make PSN backward compatible with existing huge non-IP / MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) network equipment, effectively protecting the investment of operators and customers. [0003] The network reference model of PWE3 is as follows: figure 1 As shown, in order to enable t...
