Method for non-block user data transmission in reverse multiplexing process

Abstract

A method for non-blocking transmitting user's data in negative multiplex procedure includes sending process step and receiving process step. The sending process step includes: extracts the user's cell carried by ICP cell according to VPI, VCI; confirms numbers of the section splitting one cell according to numbers of links in the group, and carries it into the ICP cell; sends the above ICP cell; the above receiving process steps includes: extracts the above ICP cell; extracts the user's data from the above ICP cell, and stores and filters the above user's data, recovers the filtered data into user's cell. The method is not affected by IMA, it can send and receive ICP cell at the time of ICP cell sent and received at both terminals, use the link message bytes remained in ICP cell to fill the user's data, so as to reach the purpose of non-blocking transmitting user's data.

Description

technical field [0001] The invention relates to a method for transmitting data, in particular to a method for transmitting data during inverse multiplexing. Background technique [0002] The ATM inverse multiplexing specification version 1.0 and version 1.1 indicate that IMA (inverse multiplexing, InverseMultiplexing for ATM) is to inversely multiplex an ATM cell stream on the basis of cells to multiple physical connections for transmission, and The far end multiplexes these cells transmitted over different physical connections into a cell stream consistent with the original sequence. Inverse multiplexing technology multiplexes multiple lower rate connections into a logical higher rate connection, and this higher rate value is approximately equal to the sum of several low rate values ​​that make up the inverse multiplexing. [0003] Periodically insert some IMA control protocol cells, namely ICP cells, at the sending end of the IMA. By receiving ICP cells, the transition of...

Problems solved by technology

[0007] In order to solve the problem of user data blocking when using the IMA protocol to transmit data in the prior art, the present invention provides a method of using ICP cells to carry user data. This method is not affected by the IMA protocol, as long as both ends can Start sending and receiving ICP cells, you can start sending and receiving user data, specifically, use the remaining "link information" bytes in the ICP cells to fill user data, so as to achieve non-blocking transmission of user data Purpose
