Embodiment Construction

[0025] Embodiments of the present invention mainly include the following two aspects:

[0026] At the entrance of the packet switching network, analyze the TDM data frame, extract the payload and the header characteristic information of the TDM data frame, encapsulate the payload and the header characteristic information of the TDM data frame into the packet switching data packet, and send Incoming packet switching network transmission;

[0027] At the egress of the packet-switched network, the payload and the header feature information of the TDM data frame are stripped from the packet-switched data packet encapsulating the header feature information of the TDM data frame, according to the header feature information of the TDM data frame The TDM data frame header is reassembled, and the TDM data frame header and payload are assembled into a TDM data frame.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention cl...

Abstract

The invention discloses a method for TDM business of packet switching network transmission, comprising the following steps: A. analyzing TDM data frame and extracting the payload and TDM assembling information; B. sealing the payload and the TDM assembling information in the packet switching data packet and sending the information to the packet switching network to be transmitted. The invention also discloses a device and a system which are used for realizing TDM business of packet switching network transmission. The invention can combine the TDM network and the packet switching network together so as to transmit the TDM business through the packet switching network.

Description

technical field [0001] The present invention relates to the technical field of network switching, in particular to a method, device and system for transmitting time division multiplexing (Time Division Multiplexing, TDM) services through a packet switching (Packet Switching, PS) network. Background technique [0002] In existing communication networks, TDM is a widely used network switching technology. In order to meet the needs of the evolution of the communication network architecture, all telecom operators are eager to integrate various communication services in a network for transmission in a lower-cost transmission mode. Due to the low cost and wide application range of the packet switching network represented by the Internet Protocol (IP) network, it has become a development trend of the communication industry to integrate various services in a unified packet switching network for transmission. Under the development trend of network integration, a method for transmitt...
