OPTICAL LINK QUALITY MONITORING IN A COMPUTER NETWORK |
摘要 |
In one embodiment, a local network device collects local optical power information for at least one of either a local optical transmit interface and a local optical receive interface of the local network device. The local network device may then exchange the local information for remote optical power information of corresponding remote optical receive and transmit interfaces of a remote network device at an opposing end of at least one corresponding optical link (fiber). For example, an exchange may use a point-to-point protocol which may dynamically determine/discover neighboring relationships between capable peer device interfaces and establish a suitable communication exchange between the capable peers. Based on the local information and exchanged remote information, the local network device may calculate an optical power loss of each corresponding optical link. |
