Embodiment Construction

[0044] The present invention utilizes the existing MPLS technology (including MPLS-TP, TMPLS, MPLS, etc.) Among them, the penultimate hop forwarding node takes the virtual label of the corresponding server group as the label of the last hop forwarding node (that is, the egress node), and performs exchange and forwarding, and then the egress node directly obtains the MAC address of the corresponding server according to the preset information table Address and forwarding can improve the exchange capability of application layer services, especially in the aspect of directional forwarding, it can take advantage of MPLS-TP technology label forwarding, and realize fast directional forwarding of application services through MPLS-TP pseudowire technology.

[0045] For each forwarding node, its method of using MPLS technology to forward the application service message includes:

[0046] Step 201: the forwarding node receives the message;

[0047] Unless otherwise specified, the forwar...

Abstract

The present invention relates to a method and a forwarding node for forwarding an application service message using MPLS technology, the method comprising: the forwarding node receives the message; the forwarding node performs multi-protocol label switching (MPLS) processing on the received message, wherein, currently When the node is the penultimate hop intermediate node (Transit), exchange the original label in the message with the virtual label of the corresponding server group; when the current node is the outgoing node (Egress PE), pop up the label in the received message , wherein different server groups correspond to different server group virtual labels; the forwarding node forwards the processed message, wherein, when the current node is an egress node, the message is processed according to the server group information corresponding to the server group virtual label Forward. The invention can realize fast and directional forwarding of content exchange.

Description

technical field [0001] The invention relates to MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) technology, in particular to a method and a forwarding node for forwarding application service messages by utilizing the MPLS technology. Background technique [0002] The PTN (Packet Transport Network) bearer network is used to carry multiple services and forward them at high speed. Under the trend of network flattening in the future, the end-to-end path of services may be shortened. With the acceleration of the IPv6 process and the clarity of the prospect, China Telecom announced that it will fully support the V6 network in 2014. The trend of network flattening in the future and increasingly urgent demands such as cloud computing put forward higher requirements on the computing load capacity of network equipment. [0003] With the development of MPLS-TP (Transport Profile for Multi-Protocol Label Switching, transport plane multi-protocol label switching) t...
