Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for processing transmission of an end-to-end service.
Background
A Seamless Multi-protocol Label Switching (Seamless MPLS) network is used as a bearer technology, and the MPLS technology is extended to an access layer network, so that all services can be MPLS encapsulated in the access layer network. An end-to-end transmission service is provided for a client by deploying a complete Label Switched Path (LSP) in an access layer, an aggregation layer and a core layer network.
Seamless MPLS is a technology that unifies end-to-end bearing, and performs MPLS encapsulation on all services in an access layer to form a unified MPLS control plane from a core to a metropolitan area and then to an access, thereby greatly reducing the difficulty of network planning and operation and maintenance. The network adopts a unified MPLS Operation, management and Maintenance (OAM) technology to protect the network and the service, thereby improving the end-to-end reliability.
The Seamless MPLS technology improves the service opening efficiency due to the flexible service connection characteristic. Seamless MPLS is a technology that any two nodes in a network can be connected through an MPLS tunnel from each node accessed to a core network, thereby ensuring smooth service and facilitating the development of services such as service wholesale, enterprise private line, and the like. MPLS continues to decrease in service operation points as it extends from core to metro, access. Originally, a Virtual Local Area Network (VLAN) is needed to associate a metropolitan area device and a core layer node, but now only the VLAN and related data need to be configured on the access device side, and an LSP can be established between all intermediate nodes through routing information to complete establishment of an MPLS tunnel and data transmission. Therefore, the Seamless MPLS reduces the service provisioning operation point and the static configuration, eliminates the coordination among different departments when the service is provisioned, and improves the provisioning efficiency.
Seamless MPLS also solves the problems of VLAN planning and VLAN expansion. Although the uniform VLAN planning in the whole network is beneficial to fault location, the VLAN planning is very complex, and the number range of the VLAN is limited. After the Seamless MPLS scheme is provided, the VLAN is divided only at the service access layer. Based on the above reasons, the application of Seamless MPLS in the current network is more and more extensive, and how to satisfy the increasingly large amount of services of Seamless MPLS is the limiting point of the networking.
Aiming at the problem that more and more services become limiting factors for the development of Seamless MPLS in the related art, no effective solution is provided.

And 7: the AGG sends the port information of the first access node, the PW destination address, the PW/Flow label from the CSG to the PW destination address and the LSP label from the CSG to the AGG to the ASBR through the ANCP message, and the ASBR forwards the ASBR to the access node through the ANCP message, wherein the mapping table contained in the MASG is an outer layer MPLS LDP label, an outer layer BGP LSP label and an inner layer BGP LSP label.
