Patent number: 11991083Abstract: An improved autonegotiation approach includes determining that a negotiated rate between a first network device and a second network device exceeds data transfer capacity over a network path downstream of the second network device. In response, a configuration message is generated and transmitted to the first network device. When received by the first network device, the configuration message causes the first network device to limit data transfer between the first network device and the second network device to no more than the downstream data transfer capacity.Type: GrantFiled: October 19, 2022Date of Patent: May 21, 2024Assignee: Level 3 Communications, LLCInventors: Steven E. Drake, Charles R. Lyman

Patent number: 10771151Abstract: A system for monitoring health of a fiber optic cable in a telecommunications system includes an optical switch for receiving a plurality of light noise signals over the fiber optic cable and measuring the intensity of at least one of the plurality of light noise signals. The measured intensity data is transmitted to a monitoring system that then compares the measured intensity to a stored threshold intensity value. The system may also include a light signal generator for providing the plurality of light noise signals. The light signal generator may include a first amplifier for generating a light noise signal, a second amplifier for generating a corresponding amplified light noise signal, and an optical splitter for converting the amplified light noise signal into the plurality of light noise signals.Type: GrantFiled: July 31, 2018Date of Patent: September 8, 2020Assignee: Level 3 Communications, LLCInventors: Steven E.
