[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0031] In order to solve the failure of BIER multicast link, the present invention proposes a method for pre-configuring the protection path. The first link and the second path are selected to calculate a preset circle sequence, and the multicast working tree and protection path are calculated according to the preset circle sequence. Configure the working path as a working entry in the BIFT table, and configure the protection path as a protection entry in the BIFT table.
[0032] Such as figure 1 Shown is the overall flowchart of the method. In step (101), the first link is selected, the second path is calculated, and the preset circle sequence is calculated. For the detailed calculation process, see figure 2 The flow chart of the algorithm is shown. In step (102) according to preset circle sequence, calculate the working tree of multicast, this part is ...
