摘要： A method and system for emulating an Ethernet link over a Sonet path to provide link integrity is disclosed. The method generally includes receiving an error code at a local Ethernet port upon detection of a link failure at a remote Ethernet port. The error code is received over a Sonet path in a Sonet path overhead. If the error code is still present after a specified period of time, the local Ethernet port is disabled. Methods for providing link stability and link availability are also disclosed.

摘要： In a data communication internetwork including a source station, an end station, and a default router for the source station, a default communication path including the default router is defined between the source station and the destination station. During operation of the data communication internetwork, a shortcut data communication path by passing the default router is established between the source station and the destination station, such that data packets transmitted by the source station are not received by the default router. After the shortcut communication path has been established, a control frame containing source-route information regarding the source station is transmitted to the router, and the source-route information is stored at the router. In this manner, the default router can efficiently direct data packets to the source station and facilitate the establishment of shortcut communication paths terminating at the source station even though the default router is bypassed by a shortcut communication path.

摘要： A method is implemented by which a Logical IP subnetwork attached (LIS) Next Hop Resolution Protocol (NHRP) client or an Emulated LAN (ELAN) subnetwork attached NHRP client in an Asynchronous Transfer Mode (ATM) network can send data to a destination LAN Emulation Client (LEC) on a different ISO layer-3 subnetwork via a data-direct Virtual Channel Connection. The method enables such a IP subnetwork attached NHRP clients to obtain the ATM address corresponding to the destination station by using the vendor-private extension within an NHRP packet. The NHRP client uses the ATM address to build a data-direct VCC over which it unicasts data bound for the destination station. The NHRP client appears to the destination LEC as any other LEC on its ELAN would appear.
摘要翻译：实现一种方法，其中附接的逻辑IP子网（LIS）下一跳解决协议（NHRP）客户端或在异步传输模式（ATM）网络中连接的NHRP客户端的仿真LAN（ELAN）子网）可以向目的地LAN仿真发送数据客户端（LEC）通过数据直接虚拟通道连接在不同的ISO 3层子网上。该方法使得这样的IP子网连接的NHRP客户端可以通过使用NHRP分组内的供应商专用扩展来获得与目的站相对应的ATM地址。 NHRP客户端使用ATM地址构建数据直接VCC，通过该数据直接VCC单播传送到目的站的数据。 NHRP客户端出现在目的地LEC，因为其ELAN上的任何其他LEC都会出现。
