Problems solved by technology

[0007] During the process of FRR switching, the platform software functional entity in the node device needs to send an ARP update message and an FRR switching message to the driver software functional entity in sequence, and the driver software functional entity needs to process the two received messages in sequence, which takes a long time. , which reduces the execution speed of the driver software functional entity, and cannot realize fast switching of MPLS TE LSP

Embodiment Construction

[0047]In the technical solution provided by the present invention, its core idea is to introduce a message arbitration mechanism in the driver software functional entity of the node device, receive all messages from the platform software functional entity, and judge whether the next message after receiving the ARP update message is FRR For switching messages, if the next message is an FRR switching message, the previously received ARP update message is merged, and only the FRR switching message is processed; otherwise, all received messages are processed normally.

[0048] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without ma...

Abstract

The present invention discloses a message processing method of a rapid rerouting mechanism, applied to node equipmen including a platform software functional entity and a drive software functional entity. The method includes the following steps that the drive software functional entity does not process address resolution protocol ARP update message but judge whether next message received after the ARP update message is rapid rerouting FRR switching message when the drive software functional entity receives the ARP update message from the platform software functional entity, if the judging result is yes, the drive software functional entity processes the ARP update message and the next message received after the ARP update message normally. The invention simplifies message processing flow path, and implements rapid switching of MPLS TE LSP.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message processing method and device in a fast rerouting mechanism. Background technique [0002] With the development of network services, the reliability of the IP (Internet Protocol, Internet Protocol) network, which is a unified multi-service bearer, must reach the level of traditional telecommunication networks. For example, the protection switching speed is less than 50ms to meet the needs of telecommunication services. [0003] In order to achieve the above purpose, MPLS TE (Traffic Engineering, Traffic Engineering) combining MPLS (Multiprotocol Label Switching, Multi-protocol Label Switching) technology and traffic engineering is proposed in the industry, by establishing an LSP (Label Switching Path, Label Switching Path) ) tunnel to reserve resources, so that network traffic bypasses congested nodes, achieves the purpose of balancing network traffic, and performs...
