Abstract
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.
Claims23
A method, comprising:
- transmitting 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, determining reachability of the destination node;
- wherein the network-testing request or response frame is not processed on an Internet Protocol (IP) layer.
1 more element
A switch, comprising:
- a transmission mechanism configured to transmit a network-testing request frame from a source node to a destination node;
- a receiving mechanism configured to receive a network-resting response frame corresponding to the request frame;
- and
- a determination mechanism configured to determine, in response to receiving the response frame, reachability of the destination node;
- wherein the network-testing request or response frame is not processed on an Internet Protocol (IP) layer.
2 more elements
An apparatus, comprising:
- means for transmitting a network-testing request frame from a source node to a destination node;
- and
- means for, in response to receiving a network-testing response frame corresponding to the request frame, determining reachability of the destination node;
- wherein the network-testing request or response frame is not processed on an Internet Protocol (IP) layer.
