    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： One embodiment of the present invention provides a system for testing reachability between two nodes within a network. During operation, the system transmits a network-testing request frame from a source node to a destination node, and in response to receiving a network-testing response frame corresponding to the request frame, the system determines reachability of the destination node. The network-testing request or response frame is not processed on an Internet Protocol (IP) layer.

    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 system. The switch includes one or more ports on the switch configured to transmit packets encapsulated based on a first protocol. The switch further includes a traffic management mechanism and a control mechanism. During operation, the control mechanism forms a logical switch based on a second protocol, receives an automatically assigned identifier for the logical switch without requiring manual configuration of the identifier, and joins a virtual cluster switch.
