Problems solved by technology

However, since the PCC cannot know that the PCE can currently receive the tunnel authorization sent by itself, after the PCE rejects the tunnel authorization request sent by itself, it will repeatedly authorize the established tunnel to the PCE, thereby reducing the PCC and PCE work efficiency

Embodiment 1

[0068] figure 2 It is a schematic flow chart of the tunnel authorization information processing method in the embodiment of the present invention Figure 1 ,Such as figure 2 As shown, the tunnel authorization information processing method in the embodiment of the present invention includes:

[0069] Step 101: Receive a tunnel authorization request sent by at least one PCC.

[0070] Here, the tunnel authorization request is used for the at least one PCC to authorize the established tunnel to the PCE; the tunnel authorization request can be sent through a PCRpt message; the tunnel authorization request (PCRpt message) carries at least one of the following information One: PCC identification information, tunnel identification information; wherein, the PCC identification information is used to identify the PCC that sends the tunnel authorization request, and the tunnel identification information is used to identify the tunnel that the PCC authorizes to the PCE, such as identif...

Embodiment 2

[0092] Figure 4 It is a schematic diagram of tunnel authorization networking between a single PCC and a single PCE in the embodiment of the present invention; Figure 4 As shown, the network node Node1 establishes a PCEP connection with PCE1 as a PCC role. Since there is no other optional PCE, when Node1 creates a local tunnel, it directly authorizes to PCE1.

[0093] Figure 5 It is a schematic flow chart of the tunnel authorization information processing method in the embodiment of the present invention Figure II , combined with Figure 4 , Figure 5 As shown, the tunnel authorization information processing method in the embodiment of the present invention includes:

[0094] Step 200: PCE1 establishes a PCEP session connection with the PCC.

[0095] In this embodiment, the PCC is Node1.

[0096] Step 201: PCE1 receives the tunnel authorization request sent by the PCC.

[0097] Here, the tunnel authorization request is sent in the form of a PCRpt message.

[0098] S...

[0109] Image 6 It is a schematic diagram of tunnel authorization networking between a single PCC and multiple PCEs in the embodiment of the present invention; Image 6 As shown, the network node Node1 establishes a PCEP connection with PCE1 and PCE2 as a PCC role, and Node1 authorizes the locally established tunnel to PCE1 and PCE2 according to the local policy.

[0110] Figure 7 It is the third schematic flow diagram of the tunnel authorization information processing method in the embodiment of the present invention, combining Image 6 , Figure 7 As shown, the tunnel authorization information processing method in the embodiment of the present invention includes:

[0111] Step 301: PCE1 receives the tunnel authorization request sent by the PCC.

[0112] Here, the tunnel authorization request is sent in the form of a PCRpt message.

[0113] Based on this embodiment, in actual application, before this step, the PCC establishes a PCEP session connection with PCE1 and PCE2...

Abstract

The invention discloses a method for processing tunnel authorization information, comprising: a path calculation unit (PCE) receives a tunnel authorization request sent by at least one path calculation client (PCC) to authorize an established tunnel to the PCE; The tunnel authorization request judges whether the preset tunnel authorization conditions are satisfied; when it is determined that the preset tunnel authorization conditions are not satisfied, sending a first message carrying first key information to the at least one PCC, so that the at least one PCC can A PCC learns the capability of the PCE to receive its own tunnel authorization request; wherein, the first key information includes at least one of the following information: authorization overload information of the PCE, receivable authorization PCC identification information, receivable Authorized tunnel identification information. The invention also discloses a PCE at the same time.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a method for processing tunnel authorization information and a Path Compute Element (PCE, Path Compute Element). Background technique [0002] With the development of software-defined network (SDN, Software Defined Network) technology, PCE is not only used as a service component for centralized path calculation, but also actively plans the tunnels established by Path Computation Client (PCC, Path ComputationClient) dynamically. and tuning work, that is, the tunnels created by the PCC can be authorized to the PCE, and then the PCE can update the path information of the tunnels as required. However, since the PCC cannot know that the PCE can currently receive the tunnel authorization sent by itself, after the PCE rejects the tunnel authorization request sent by itself, it will repeatedly authorize the established tunnel to the PCE, thereby reducing the PCC and P...
