Embodiment Construction

[0016] The embodiment of the present invention provides a method for a three-layer virtual link supporting multiple line cards, the method comprising: after the main control board receives the PWE3 data packet sent by the remote device, obtains the destination IP address in the PWE3 data packet , wherein, the destination IP address is the IP address of the service processing board; the obtained IP address and the corresponding relationship between the IP address and the service processing board saved by itself, and the PWE3 data packet is routed to the corresponding service processing board.

[0017] Such as figure 1 As shown, the embodiment of the present invention provides a three-layer method for supporting multiple line cards, and the specific steps include:

[0018] Such as Figure 1A As shown, the existing technology has a network structure applicable to service forwarding, and the specific application environment is:

[0019] External E1, such as PBX, etc., and the na...

Abstract

The invention discloses a method and a device for supporting multiple line cards by three layers of pseudo wires, which are used in the technical field of communication. The method comprises the following steps: after receiving a PWE3 (pseudo-wire emulation edge-to-edge) data packet from a far-end device, a main control panel acquires a target IP address in the PWE3 data packet, wherein the target IP address is the IP address of a service processing board; and the PWE3 data packet is routed to the corresponding service processing board in accordance with the correspondence relationship between the acquired and stored IP addresses and service processing boards. By using the method and the device, the data packet can be directly routed to the target service processing board by setting the target IP address of the PWE3 data packet, thereby solving the problem that users supported by the device are reduced as long as a service forwarding board is added to the device.

Description

technical field [0001] The present invention relates to the technical field of end-to-end Layer 2 service bearer of communication technology broadband access, in particular to a method and device for a Layer 3 virtual link supporting multiple line cards. Background technique [0002] With the development of IP data network, IP network itself has very strong expandability, upgradeability, compatibility and interoperability. However, the upgrade, expansion, and intercommunication flexibility of the traditional communication network is relatively poor, limited by the transmission method and service type, and the new network is also poor in commonality, which is not suitable for interoperability management. Therefore, in the process of upgrading and expanding the traditional communication network, it should be considered whether to establish a repeated network or make full use of existing or public network resources. PWE3 (Pseudo-Wire Emulation Edge to Edge, Pseudo-Wire Emulati...
