METHOD FOR CONTROLLING STARTING/RESTARTING OF MESSAGE TRANSFER PART LEVEL 3 AND SIGNAL AAL IN DISTRIBUTED ATM EXCHANGER

摘要

1. TECHNICAL FIELD OF THE INVENTION;Message transfer level 3 and signaling ATM adaptation layer start / restart control method in a decentralized ATM switch.;2. The technical problem to be solved by the invention;In order to flexibly respond to changes in system resource status, to secure signal transmission paths for signal message transmission and signal network control.;3. Summary of Solution to Invention;Message transfer and signaling through level 3 and signaling control distributed to multiple processes during initial startup of the system, and through startup control procedures to collect and distribute process numbers of functional blocks of the ATM adaptation layer and to restart specific blocks during operation. It secures the signal transmission path for network control and reduces the signal in the system according to the startup by using one block in the message delivery unit as the startup control block.;4. Important uses of the invention;Used to implement the functionality of MTP-3 and SAAL in ATM switches.
