Problems solved by technology

[0004] figure 1 In the network topology shown in , when a link in the Ethernet fails, the TDM data service cannot be protected without loss, and the service recovery time depends on the performance of the adopted carrier-grade switching equipment or supporting RSTP switching equipment; The self-healing time of carrier-grade Ethernet switching equipment is relatively short, but the equipment is expensive and cannot be widely promoted; the price of RSTP-supporting Ethernet switching equipment is relatively low, but the self-healing time is long

Abstract

The invention discloses a transmission method and a device of time division multiplexing data services, which are applied to an Ethernet. The method comprises the following steps: protocol converters of a home terminal and an opposite terminal respectively divide the network into at least two virtual local area networks according to an Ethernet protocol, and are interconnected by the at least two virtual local area networks; and the protocol converters of the home terminal and the opposite terminal receive or send time division multiplexing data by the at least two virtual local area networks. The device comprises an Ethernet switching module and a programmable logic module. The technical proposal realizes nondestructive protection when TDM data service data is transmitted based on the Ethernet and enhances the reliability of the network.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a transmission method and device for time-division multiplexing data services. Background technique [0002] At present, with the rapid increase of data services in the communication field, the requirements for the utilization rate of communication channels are also increasing. The Ethernet communication network based on packet switching statistical multiplexing has become more and more prominent in solving this situation. Communication The trend of network IP is gradually obvious. Although data services occupy more and more bandwidth in communication networks, real-time services based on TDM (Time Division Multiplex and Multiplexer, Time Division Multiplexer) transmission cannot be ignored, and the TDM services have higher requirements on transmission quality. In order to ensure the transmission of TDM data services on the Ethernet network, there are var...
