Method and system for providing security to asynchronous transfer mode emulated local-area networks

A LAN Emulation Server (LES) for serving a Asynchronous Transfer Mode (ATM) emulated local-area network (LAN) having a security mechanism, wherein said ATM emulated LAN is also served by a Broadcast and Unknown Server (LES/BUS) and a LAN Emulation Configuration Server (LECS), said LES comprising:

• means for receiving a LE_JOIN_REQUEST from a LE client;
• means for sending a LE_CONFIGURE_REQUEST to a LECS utilizing information within said LE_JOIN_REQUEST, in response to the receipt of said LE_JOIN_REQUEST;
• means for receiving a LE_CONFIGURE_RESPONSE from said LECS;
• means for determining whether or not said LE_CONFIGURE_RESPONSE indicates a success;
• and
• means for sending a LE_JOIN_RESPONSE with a success status to said LE client, in response to a determination that said LE_CONFIGURE_RESPONSE indicates a success, such that said LE client is allowed to join an ATM emulated LAN having said LES and said LECS.

A computer program product for providing a security mechanism to an Asynchronous Transfer Mode (ATM) emulated local-area network (LAN), wherein said ATM emulated LAN is served by a LAN Emulation Server (LES), a Broadcast and Unknown Server (BUS), and a LAN Emulation Configuration Server (LECS), said computer program product comprising:

• program code means for receiving a LE_JOIN_REQUEST from a LE client at a LES;
• program code means for sending a LE_CONFIGURE_REQUEST from said LES to a LECS utilizing information within said LE_JOIN_REQUEST, in response to the receipt of said LE_JOIN_REQUEST;
• program code means for receiving a LE_CONFIGURE_RESPONSE from said LECS at said LES;
• program code means for determining whether or not said LE_CONFIGURE_RESPONSE indicates a success;
• and
• program code means for sending a LE_JOIN_RESPONSE with a success status from said LES to said LE client, in response to a determination that said LE_CONFIGURE_RESPONSE indicates a success, such that said LE client is allowed to join an ATM emulated LAN having said LES and said LECS.
