METHOD FOR ESTABLISHING CONNECTION BETWEEN FRAME RELAY NETWORK AND ATM NETWORK USING NETWORK MANAGEMENT SYSTEM IN DISTRIBUTED ENVIRONMENT

摘要

PURPOSE: A method for establishing a connection between a frame relay network and an ATM(Asynchronous Transfer Mode) network using a network management system in a distributed environment is provided to extend a range of connection establishing function by designing a gateway system and devising a connection establishing procedure. CONSTITUTION: After a gateway system has been operated(S1), information associated with both ends together with a connection establishing command are received through IDL(Interface Definition Language)(S2). If an exchange for providing FrAtm Port(Frame relay ATM Port) is detected(S3), the corresponding information are stored a buffering database(S4), and configuration information are extracted from the database(S5). If a provisioning mode(S6), the associated parameters are sent to an adapter(S7). A Virtual Framer is set(S8), and each address of FrAtm and Atmif(Asynchronous Transfer Interface) is set to a Next point address of the opposite side(S9). A Dlci(Data Link Connection Identifier) number of frame relay is mapped with Vpi(Virtual Path Identifier)/Vci(Virtual Channel Identifier) in Atm(S10). Traffic parameter mapping between the frame relay and the Atm is performed(S11). The provisioning mode is set(S12).
