Method for processing transannular service and intersected node

Abstract

Disclosed are a method for processing an inter-loop service and a crossing node. The method includes: a first crossing node of a source loop network and a destination loop network receiving an inter-loop message transmitted in a first direction in the source loop network, wherein the inter-loop message includes a source loop channel label and a first destination loop node indication label; determining a first destination loop channel label according to the first destination loop node indication label; replacing the source loop channel label of the inter-loop message with the first destination loop channel label; and in the destination loop network, sending to a leaving loop node the inter-loop message including the first destination loop channel label in a second direction. The crossing node includes: a receiving unit, a first determination unit, a first replacing unit and a first sending unit. The method and crossing node of the embodiments of the present invention can avoid respectively configuring different inter-loop forwarding policies for each service, so that the overhead of processing the inter-loop service can be reduced, and the efficiency of processing the inter-loop service can be improved.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for processing cross-ring services and an intersection node in the field of communications. Background technique [0002] Multi-Protocol Label Switching (MPLS for short) is a technology for fast data packet switching and routing, and MPLS can realize fast forwarding of packet services. A traditional MPLS-based network adopts fast rerouting (Fast ReRoute, referred to as "FRR") and automatic protection switching (Automatic Protection Switching, referred to as "APS") and other technologies to protect the network. However, the configuration workload of these technologies is large, and the network resource overhead is also large. [0003] Traditional transport networks widely use ring structures. Therefore, with the wide application of MPLS technology in the field of transport, especially the packet transport network (Packet Transport Network, referred to as "PTN") technology b...

AI Technical Summary

Problems solved by technology

Therefore, for each cross-ring service, the intersecting nodes need to configure different cross-ring forwarding strategies respectively. Due to the large number of services, the system overhead is relatively large
