Problems solved by technology

[0023] Since there are only 4K service labels for QinQ access to PWE3, and the intermediate devices of the QinQ network need to support QinQ and need to know the user's MAC address, the scalability of packet transmission through QinQ access to PWE3 is poor.

Embodiment Construction

[0052] The core idea of ​​the present invention is to provide a method and system for PWE3 access through Mac-in-Mac, so that users at both ends of the network can access through Mac-in-Mac, and transmit to the opposite end through the PWE3 channel, which enhances the flexibility of the network sex.

[0053] The present invention provides a system for end-to-end pseudowire analog access. In this embodiment, both ends are accessed through Mac-in-Mac as an example. The schematic diagram of the network is shown in Figure 3. - Establish PWE3 channel between PEs, run Mac-in-Mac between U-PE and N-PE, Mac-in-Mac message processing unit is set in U-PE and N-PE, support Mac-in-Mac Packet encapsulation / decapsulation operation. The Mac-in-Mac domains on both sides are independent, so the service tags on both sides are allocated independently. In Figure 3, the left Mac-in-Mac domain uses I-TAG-1 to represent a certain user, such as the voice service of user 1, while the right The Mac-i...

Abstract

This invention relates to methods and system of end-to-end pseudo-line simulative cut-in the field of communication technology. PWE3 switch in through Mac-in-Mac; transmit data as Mac-in-Mac report manner between the U-PE equipment of the user periphery oriented and N-PE equipment of the network periphery oriented. The invention achieves the cut-in of PWE3 channel through Mac-in-Mac; increase the network flexibility, so that TAG business of business operators can transmit to the other side through PWE3 channel, to have the same type of treatment to the same business type of users.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for end-to-end pseudowire analog access. Background technique [0002] PWE3 (end-to-end pseudowire emulation) is an end-to-end Layer 2 service bearer technology, which belongs to the point-to-point L2VPN (Layer 2 Virtual Private Network). In the two PEs of the PSN (Public Switched Network) network, it uses LDP (Label Distribution Protocol) / RSVP (Resource Reservation Protocol) as signaling to simulate various Layer 2 services at the CE (User Edge Device) end through tunnels , such as various Layer 2 data packets, bit streams, etc., so that Layer 2 data at the CE side can be transparently transmitted in the PSN network. [0003] FIG. 1 is a schematic diagram of a reference model of an existing PWE3 accessing an Ethernet. PE1 and PE2 are network edge devices. A PW virtual private line, namely PWE3 channel, is established between PE1 and PE2. CE1 ...
