Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0026] Such as figure 1 As shown, the embodiment of the present invention provides a method for deploying a tunnel service, the method including:

[0027] S10, the head node of the tunnel assigns the extended label switched path identifier to the newly created label switched path LSP and sends it to the downstream node along with the quintuple information of the newly built LSP in the path establishment message; wherein, when tunnel re-optimization occurs, The extended label switched path identifier assigned by the newly established LSP follows the extended label switched pa...

Abstract

The invention discloses a method for deploying tunnel services. The method comprises the following steps of: distributing an extended label switched path (LSP) identifier for a newly established LSP through a head node of a tunnel and carrying the LSP identifier and quintuple information of a newly established LSP to be transmitted to a downstream node in a path establishing message, wherein a removed extended LSP identifier of the original old LSP is adopted for the extended LSP identifier distributed for the newly established LSP when the tunnel is re-optimized; saving a corresponding relationship between the extended LSP identifier and the quintuple information of the newly established LSP after an intermediate node of the tunnel receives a path establishing message; and searching corresponding quintuple information so as to deploy the tunnel services according to the saved extended LSP identifier of the LSP when the intermediate node of the tunnel deploys the tunnel services. According to the method above, the tunnel re-optimization can be avoided so as not to cause ineffective tunnel service deployment. The invention also discloses a system for deploying the tunnel services.

Description

technical field [0001] The present invention relates to the technical field of distributed network traffic engineering, in particular to a method and system for deploying tunnel services. Background technique [0002] In the IP (Internet Protocol, Internet Protocol) / MPLS (Multi Protocol Label Switch, Multi-Protocol Label Switching) network of data communication, a dynamic LSP (Label Switched Path, Label Switched Path) passing through the tunnel is usually used to represent the actual operation of the tunnel Status, such as the path that the tunnel passes, the bandwidth of the tunnel deployment and other data information. [0003] Usually, an LSP is uniquely represented by a five-tuple of tunnel identifier (TunnelId), label switched path identifier (LSPId), tunnel destination address (Destination Address), tunnel source address (Source Address) and tunnel extension identifier (ExtendId). [0004] When a tunnel is re-optimized, a new LSP is usually created to represent better...
