Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0021] The Ethernet service on the original MSTP network is carried by EOS (Ethernet Over SDH, SDH carries Ethernet data packets). The inventor considers that, in the embodiment of the present invention, when intercommunication between the packet switching network and the TDM network is realized, the EOS service is converted, and then processed and connected to the packet switching core through a single board. The dual-plane equipment for packet switching and TDM switching realizes the docking with the original MSTP equipment, and the EOS service in the MSTP equipment...

Abstract

The invention discloses a packet-switching network and a TDM (Time Division Multiplexer) network interworking service protection method as well as network equipment. The method comprises the following steps of: interacting a TDM service between a mainboard and a TDM exchange core when the mainboard fails or needs exchanging; interacting an Ethernet data packet EOS (Embedded Operating System) service which is borne by a synchronous digital series and converted by service types with a packet-switching core; switching SDH (Synchronous Digital Hierarchy) protection and interacting the TDM servicebetween a trigger backboard and the TDM exchange core; and submitting the EOS service to the backboard, deleting the EOS service on the mainboard and interacting the EOS service converted by service types between the trigger backboard and the packet-switching core. The invention also discloses network equipment and can realize the communication of the packet-switching network and the TDM network and prevent the EOS service from being interrupted for a long time when exchanged single boards are abnormal or need replacing.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a service protection method and network equipment for interworking between a packet switching network and a TDM network. Background technique [0002] With the development of the network, the bandwidth of various devices in the network is getting higher and higher, and the burst bandwidth of the device is getting bigger and bigger. The traditional connection-oriented TDM (Time Division Multiplexing, time division multiplexing) switching equipment, such as SDH (Synchronous digital hierarchy, synchronous digital series), MSTP (Multi-Service Transmission Platform, multi-service transmission platform) and other equipment, it is difficult to meet the needs of operators. PTN (Packet Transmission Network, packet transmission network) equipment came into being. In the PTN equipment, the business is transmitted in the form of packets, which is difficult to interoperate with the ori...
