A METHOD AND SYSTEM FOR TRANSPORTING ATM MESSAGE OVER IP-BASED NETWORK

摘要

A method and system for transporting ATM message over IP-based network, the method provides inter-communication between the first ATM gateway of the first ATM network and the second ATM gateway of the second ATM network, when the first ATM gateway sends ATM message to the second ATM network, the first ATM gateway looks up the mapping table according to the ATM parameter of the ATM message, obtains the corresponding IP parameter; the first ATM gateway performs the IP encapsulation for the ATM message using the IP parameter and obtains IP message, and sends the IP message to the second ATM gateway through IP network. The present invention sets the mapping table on the first ATM gateway, and performs the corresponding encapsulation according to the mapping table, it enables the ATM message to be transported to the required device address in the remote ATM network without the large scale device change.
