    • A method for providing a security mechanism to an Asynchronous Transfer Mode (ATM) emulated local-area network (LAN) is disclosed. The ATM emulated LAN is served by a LAN Emulation Server (LES), a Broadcast and Unknown Server (BUS), and a LAN Emulation Configuration Server (LECS). After receiving a LE_JOIN_REQUEST from an LE client within the emulated LAN, the LES forms a LE_CONFIGURE_REQUEST on behalf of the LE client, by utilizing the information from the LE_JOIN_REQUEST. The LES then sends the LE_CONFIGURE_REQUEST to the LECS. In turn, the LECS sends back a LE_CONFIGURE_RESPONSE to the LES. After receiving the LE_CONFIGURE_RESPONSE from the LECS, a determination is made as to whether or not a status field within the LE_CONFIGURE_RESPONSE indicates a success and a target ATM address field within the LE_CONFIGURE_RESPONSE contains an ATM address of the LES. If both of the above-mentioned conditions are met, the LES then sends a LE_JOIN_RESPONSE with a success status back to the requesting LE client such that the requesting LE client is allowed to join the emulated LAN.
    • 公开了一种用于向异步传输模式(ATM)模拟的局域网(LAN)提供安全机制的方法。 ATM模拟LAN由LAN仿真服务器(LES),广播和未知服务器(BUS)和LAN仿真配置服务器(LECS)提供。 在模拟LAN内的LE客户端收到LE_JOIN_REQUEST后,LES通过利用LE_JOIN_REQUEST中的信息代表LE客户端形成LE_CONFIGURE_REQUEST。 LES然后将LE_CONFIGURE_REQUEST发送到LECS。 反过来,LECS将LE_CONFIGURE_RESPONSE发送回LES。 在从LECS接收到LE_CONFIGURE_RESPONSE之后,确定LE_CONFIGURE_RESPONSE中的状态字段是否指示成功,并且LE_CONFIGURE_RESPONSE内的目标ATM地址字段包含LES的ATM地址。 如果满足上述两个条件,则LES然后将具有成功状态的LE_JOIN_RESPONSE发送回请求的LE客户端,使得允许请求的LE客户端加入仿真的LAN。

    • A service is configured by provisioning the service for a facility on a network access device (NAD). The service endpoint is created in an operationally disabled state responsive to provisioning the service. A first network interface unit (NIU) is detected connecting to the facility. The first NIU has an identification code associated therewith. The service transitions to an operationally enabled state responsive to detecting the first NIU connecting to the facility. The identification code is associated with the facility. The first NIU is detected disconnecting from the facility. The service transitions to an operationally disabled state responsive to detecting the first NIU disconnecting from the facility. A second NIU is detected connecting to the facility. The second NIU has an identification code associated therewith. The identification code of the second NIU is compared with the identification code of the first NIU. The service transitions to an operationally enabled state if the identification code of the second NIU matches the identification code of the first NIU indicating that the first and second NIUs are the same NIU.
    • 通过为网络访问设备(NAD)上的设施提供服务来配置服务。 响应于提供服务,服务端点被创建在可操作地禁用的状态中。 检测到连接到设施的第一网络接口单元(NIU)。 第一NIU具有与之相关联的识别码。 响应于检测连接到设施的第一NIU,该服务转换到可操作地启用状态。 识别码与设施相关联。 检测到第一个NIU与设备断开连接。 响应于检测到与设施的第一NIU断开连接,该服务转换到可操作地禁用状态。 检测到连接到设备的第二个NIU。 第二NIU具有与之相关联的识别码。 将第二NIU的识别码与第一NIU的识别码进行比较。 如果第二NIU的识别码与第一NIU的识别码匹配,指示第一NIU和第二NIU是相同的NIU,则服务转换到操作使能状态。
