Embodiment Construction

[0021] The following reference Figure 2 to Figure 4 This preferred embodiment will be described in detail.

[0022]In a preferred embodiment of the present invention, the chassis-type communication device can simultaneously bear the PTN network and the SDH network, and use a virtual private wire service (Virtual Private Wire Service, VPWS) to establish a connection between the SDH network and the PTN network. Specifically, the user network side interface (UseNetwork interface, UNI) for accessing the SDH network and the network node interface (Network to Networksinterface, NNI) for accessing the PTN network can be set through the network management board command, wherein, The UNI interface can be set on any SDH port of the service board as required, and the NNI interface is set on a PTN port of the switching board, and a two-layer virtual private network (Virtual Private Network, VPN) service channel is established between the UNI and the NNI, from Physically establish a chan...

Abstract

The invention discloses a method for synchronous digital hierarchy (SDH) and packet transmission network (PTN) network alarm linkage and a system applying the method. The method includes: configuring a virtual private wire service (VPWS) for each frame-type communication device, and determining the user network interface (UNI) included in it for accessing the SDH network and the network for accessing the PTN network A node interface (NNI); a service channel is established between the UNI interface and the NNI interface through a two-layer virtual private network (VPN), and the logical correspondence between the UNI interface and the NNI interface and the predetermined identification is established; based on multi-protocol label switching-transfer ( MPLS‑TP) Pseudowire (PW) operation management and maintenance (OAM) technology detects the status of the UNI interface and the NNI interface in real time; when the status of the UNI interface or the NNI interface changes, the corresponding alarm is controlled based on the logical correspondence. In this way, the problem in the prior art that the SDH network and the PTN network cannot realize the monitoring, management and protection switching of each other's management message transmission can be solved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for SDH and PTN network alarm linkage and a system applying the method. Background technique [0002] Power system synchronous digital system (Synchronous Digital Hierarchy, SDH) can carry out various services, such as telephone, data, digital video, etc., and the quality of the service can be strictly guaranteed, with high stability, high speed, high reliability, etc. advantage. The network has been running stably for many years and is currently the main network of the transmission network. With the rapid development of the power communication network, the packet transport network (Packet Transport Network, PTN) network core is IP-based, packet-oriented services, and the bandwidth utilization rate is high, and the bandwidth can be allocated dynamically. insufficient. Since the PTN network and the SDH network are based on different protocols, although the standard...
