Abstract
In an intercommunication apparatus (1), a frame converting portion (30) is provided for interconversion between MAC (Media Access Control) frame encapsulation data and LLC/SNAP (Logical Link Control/SubNetwork Attachment Point) encapsulation data by the use of information related to IPOA (Internet Protocol over Asynchronous Transfer Mode) terminals (200a-200c) and registered in an IPOA server (40).
Claims6
An intercommunication apparatus (1) for carrying out communication between one and another of LAN (Local Area Network) emulation terminals (100a, 100b, 100c) and IP (Internet Protocol) over ATM (Asynchronous Transfer Mode) terminals (200a, 200b, 200c), said apparatus comprising:
- an IPOA (IP over ATM) server (40) which stores information related to said IP over ATM terminals;
- an encapsulating portion (50) for encapsulating input data;
- a frame converting portion (30) for carrying out, by the use of the information stored in said IPOA server, interconversion between MAC (Media Access Control) frame encapsulation data and LLC/SNAP (Logical Link Control/SubNetwork Attachment Point) encapsulation data prepared by said encapsulating portion;
- and
- a bridge portion (20) for exchanging data between said LAN emulation terminals and said frame converting portion.
