[0016] The present invention provides a method for implementing PTN forward compatibility with MSTP ring network service channel protection, which ensures the channel protection when the PTN equipment is forward compatible with the MSTP equipment. The present invention will be described in detail below in conjunction with the drawings.
[0017] figure 1 It is a schematic diagram of the normal operation of PTN forward compatible MSTP ring network, such as figure 1 As shown, the ring network includes a PTN network and an MSTP network that are connected to each other. The PTN network is composed of a number of PTN devices connected in series. The MSTP network is composed of a number of MSTP devices connected in series, among which A, B, C, G, H, I PTN equipment, D, E, F are MSTP equipment, PTN equipment C, G adapts MSTP service to PTN in VPWS or VPLS mode, MSTP equipment E has business connection with PTN equipment A, A and E are business initiating equipment And termination equipme...
