specific Embodiment 1

[0055] The problem to be solved in this specific embodiment: In order to avoid various problems caused by dynamically switching the isolation group or multicast group where Leaf_C is located in the existing implementation scheme, a new protection method that does not need to dynamically switch Leaf_C is proposed. Through this embodiment, fast protection switching of P2MP layer 2 multicast can be realized based on the existing P2P PW in the PTN network, and the switching efficiency is not affected by the increase in the number of Leaf_Cs; in addition, this embodiment will not additionally occupy the quality of different user services ( Quality of Service, referred to as QOS) resources, will not affect the switching capacity of PTN equipment, to ensure full utilization of network bandwidth.

[0056] The following technical solutions are adopted in this specific embodiment:

[0057] The core technical solution of this specific embodiment is to decompose the UNI side CIP and NNI s...

specific Embodiment 2

[0064] In order to avoid various problems caused by dynamically switching the isolation group or multicast group where Leaf_C is located in the existing implementation scheme, a new protection method that does not need to dynamically switch Leaf_C is proposed, including the following steps:

[0065] Step 1: P2MP layer 2 multicast service configuration:

[0066] When the user configures and delivers the P2MP Layer 2 multicast service MTREE on the PTN device, the processing flow of the multicast configuration adaptation module is as follows: Image 6 shown.

[0067] Firstly, the P2MP service is adapted to the main and standby two VPLS and sent to the service switching chip, and the VPN72221ID is internally allocated. It is necessary to ensure that it will not conflict with the VPN72221ID used by ordinary VPLS. The active and standby relationship here is a relationship defined by us, which is used for subsequent protection switching processing, and the service switching chip doe...

Abstract

The present invention provides a protection switching method, device and storage medium for a point-to-multipoint layer-2 multicast service. The method includes: decomposing each point-to-multipoint layer-2 multicast service into two virtual private local area networks VPLS ; Create a multicast group for VPLS; associate forwarding equivalence class FECs for the multicast groups, and form the associated FECs into a multicast protection group; use the multicast protection group to perform protection switching on the transmission of Layer 2 multicast services. The present invention solves the problems in the related art that the switching efficiency of multicast members is low and affects the switching capacity of equipment when switching multicast traffic, and achieves the effects of ensuring switching time and improving switching efficiency.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a protection switching method, device and storage medium for a point-to-multipoint layer-2 multicast service. Background technique [0002] A packet transport network (Packet Transport Network, PTN for short) is a transport technology based on packet switching and supporting multiple service bearers. In order to ensure service reliability, it is necessary to support fast protection switching of various services, and the switching performance requirement of the telecommunication network is that the switching time is not greater than 50ms. [0003] Point-to-MultiPoint (P2MP for short) is a PTN network that transmits multicast services from a single sending device (multicast source) to multiple receiving devices (multicast receivers) in the network. transmission technology. In order to improve the utilization of network bandwidth and avoid backbone network congestion, it is n...
