Patent ID: 7720088

Claim:
A method for Time Division Multiplexing (TDM) data transport, comprising: setting up a TDM logical port on a transmitting side and on a receiving side respectively, creating a relationship between the TDM logical port of the transmitting side and that of the receiving side, and storing information of the relationship at the transmitting side and at the receiving side respectively; deciding whether the received data is TDM data according to data source in the transmitting side, if the received data is the TDM data, mapping the received TDM data to the TDM logical port of the transmitting side, otherwise, assigning a CID according to the header of the received package data, performing a packet adaptation process and an encapsulation edit process on the received package data, and sending the package data to the receiving side; mapping TDM data to the TDM logical port of the transmitting side, acquiring encapsulation information stored at the transmitting side, encapsulating a TDM data flow transmitted from the TDM logical port of the transmitting side and the information of the relationship into a data package according to the encapsulation information, and then sending the data package to the receiving side; and deciding whether the received data is the TDM data according to the CID of the received data package in the receiving side, if the received data is the TDM data, acquiring the de-encapsulation information and the TDM logical port identifier of the receiving side according to the information of the relationship of the received data package; otherwise, inquiring corresponding packet adaptation processing information according to the CID, performing the corresponding packet adaptation process and the de-encapsulation process on the data package, and sending the data to a corresponding package interface; acquiring de-encapsulation information according to the information of the relationship of the received data package at the receiving side, de-encapsulating the data package according to the de-encapsulation information, and mapping the de-encapsulated TDM data to the TDM logical port of the receiving side.
