Method and apparatus for the fast detection of connectivity loss between devices in a network

摘要

A method and apparatus for quickly determining the status of a network device in a network communicates status inquiry messages over the forwarding plane of one network devise to at least one neighboring network device. The status inquiry messages indicate the connectivity status with at least one neighboring network device.

1. A system for communicating a status of a network device in a network, the system comprising:
a control plane adapted to process packets to resolve forwarding information by communicating with other devices in the network; a forwarding plane adapted:
to forward packets based on previously resolved forwarding information stored at the network device; andto generate and communicate, to a neighboring network device, a connectivity status message indicating a status of the network device.
