ABSTRACT:
An asynchronous transfer mode LAN switching hub device using IEEE P1355 system and its control method. The invention comprises: a central processing unit module for controlling and generalizing the switching hub entire system; a switching matrix module for executing a high speed switching function of IEEE P1355 packet a; ATM-to-P1355 converting module for converting ATM cells received from ATM communication network or ATM terminal and transmitting to said switching matrix module; an MA-to-P1355 converting module for converting ethernet, token ring, FDDI packet to IEEE P1355 packet and transmitting to said switching matrix module; a communication managing module for managing the communication network; MPEG-to-P1355 converting module for transmitting MPEG video; ISDN-to-P1355 converting module for associating with narrow band width ISDN; additional application interface module; and DS (Data/Strobe) link being a high speed serial link interconnecting each module, and there is effect having an adaptability and expandability that a high speed data transmitting and receiving among the modules is possible by low cost, and even when equipping a necessary application module in future, an interconnection with existing modules is easy by merely utilizing DS link.
