Embodiment Construction

[0028] In order to realize the local tunnel management entity on the middle and end nodes of the tunnel, the concepts of access tunnel and signaling tunnel are introduced.

[0029] The signaling tunnel is the tunnel entity of the existing RSVP-TE dynamic tunnel on the head node. The main significance of the existence of the signaling tunnel is to trigger the signaling creation of the RSVP-TE dynamic tunnel, and to deploy some services based on the entire tunnel, such as deploying traffic engineering for rapid rerouting (TE-FRR), bandwidth, etc.

[0030] The access tunnel is a tunnel entity set up to meet the needs of deploying related services on the middle and tail nodes of the RSVP-TE dynamic tunnel. The access tunnel itself will not trigger the creation of signaling, and is only used for some service deployments related to intermediate and tail nodes, such as TP-OAM detection and traffic import.

[0031] In the present invention, the intermediate and tail nodes are also re...

Abstract

The invention discloses a method and an apparatus for disposing services in an RSVP-TE dynamic tunnel. An access type tunnel is configured to be associated with a far-end signaling type tunnel at a non-head node. A service configuration is carried out in the access type tunnel. The invention also discloses an apparatus for disposing services in the RSVP-TE dynamic tunnel. According to the technical scheme in the invention, the requirement of disposing services at the non-head node can be satisfied and the service disposing mechanism is flexible and convenient. Besides, a manner of tunnel identification section division can be adopted to the access type tunnel and the far-end signaling type tunnel to ensure that the two are entirely independent in the aspect of configuration and mutual interferences between the two kinds of tunnels on management and service are avoided.

Description

technical field [0001] The present invention relates to a resource reservation protocol (RSVP-TE, Resource ReServation Protocol-Traffic Engineering) dynamic tunnel (Tunnel) technology based on traffic engineering extension, in particular to a method and device for service deployment in the RSVP-TE dynamic tunnel. Background technique [0002] In a conventional RSVP-TE dynamic tunnel, usually only the head node of the tunnel has a relevant tunnel entity for service configuration, but there is no tunnel entity for service configuration at the intermediate node and tail node of the tunnel. On these non-head nodes, there are only some live state blocks dynamically generated by Resource Reservation Protocol (RSVP) signaling, such as Path State Block (PSB, Path Sate Block), Reserved State Block (RSB, Reservation State Block )Wait. Due to this feature, many services of the RSVP-TE dynamic tunnel can only be configured on the head node. [0003] However, there are currently some b...
