摘要： One embodiment of the present invention provides a system for detecting a path between two nodes. During operation, the system transmits a network-testing request frame, which includes a time-to-live (TTL) field within a Transparent Interconnection of Lots of Links (TRILL) header, from a source node to a destination node. In response to receiving a network-testing response frame sent from an intermediate node, the system increments the TTL value by 1 and re-transmits the network-testing frame to the destination node. In response to receiving a network-testing response frame sent from the destination node, the system determines a path between the source node and the destination node. The network-testing request or response frames is not processed on an Internet Protocol (IP) layer.
摘要翻译：本发明的一个实施例提供一种用于检测两个节点之间的路径的系统。在操作期间，系统发送网络测试请求帧，该帧包括从源节点到目的地节点的多个链路（TRILL）头部的透明互连中的生存时间（TTL）字段。响应于接收到从中间节点发送的网络测试响应帧，系统将TTL值递增1，并将网络测试帧重新发送到目的地节点。响应于接收到从目的地节点发送的网络测试响应帧，系统确定源节点和目的节点之间的路径。网络测试请求或响应帧不会在Internet协议（IP）层上处理。

摘要： One embodiment of the present invention provides a switch system. The switch includes a port that couples to a server hosting a number of virtual machines. The switch also includes a link tracking module. During operation, the link tracking module determines that reachability to at least one end host coupled to a virtual cluster switch of which the switch is a member is disrupted. The link tracking module then determines that at least one virtual machine coupled to the port is affected by the disrupted reachability, and communicates to the server hosting the affected virtual machine about the disrupted reachability.

摘要： One embodiment of the present invention provides a switch that facilitates name services in a virtual cluster switch. The switch includes a name service database indicating at least one media access control (MAC) address learned at a second switch. The switch also includes a control mechanism. During operation, the control mechanism distributes information on a locally learned MAC address to the second switch. In addition, the control mechanism receives information on a MAC address learned at the second switch.
