Method and apparatus for testing the responsiveness of a network device
First Claim
1. A method of determining responsiveness of a network device in a network including a plurality of interconnected network devices, the method comprising the steps of:
- when a first network device loses contact with a second network device, the first network device requesting that a proxy network device contact the second network device and report back to the first network device whether the requested contact is successful.

Abstract
Method and apparatus for fault management of computer networks which utilizes a proxy or recruit network device to test the responsiveness of a network device. When a first network device loses contact with a second network device, the first network device uses a proxy network device to determine if the second network device can be reached and reports back to the first network device whether the contact attempt was successful. The proxy network device may contact the second network device through a different path and/or protocol than used by the first network device.
