Abstract: 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.

Abstract: A method and apparatus for controlling delay over a data path in a device for transporting Ethernet packets over an optical transport network. The device is configured to receive an incoming clock signal having a first frequency and an incoming data signal and to output an outgoing clock signal having a second frequency and an outgoing data signal. One or more delays over the data path in the device are measured in a predetermined measurement period. A phase adjustment amount is determined based on the one or more measured delays over the data path in the predetermined measurement period, and based on the determining phase adjustment amount, a phase of the outgoing clock signal is adjusted by a phase locked loop in such a way that the delay over the data path in the device is substantially equal to a fixed delay value.

Abstract: A method of enabling transport of symmetric latency-sensitive constant-bit-rate (CBR) client data streams over an optical transport network (OTN) is provided. The method performs, utilizing an OTN wrapping device, an OTN wrapping operation on a received first constant-bit-rate (CBR) client data stream to form a first framed OTN data stream. The method determines a static wrapping delay induced on the first CBR client data stream by the OTN wrapping operation, performs, utilizing the OTN wrapping device, an OTN unwrapping operation on a received second framed OTN data stream to extract a second CBR client data stream from the second framed OTN data stream, determines a static unwrapping delay induced on the second framed OTN data stream by the OTN unwrapping operation, and equalizes the static wrapping and unwrapping delays by adjusting, at the OTN wrapping device, at least one of the static wrapping and unwrapping delays.

Abstract: An Ethernet adapter system may include a transmitter to insert a payload type identifier sequence in a generic frame procedure header to indicate that a network is a converged enhanced Ethernet network. The transmitter may insert idle sequences in a stream of data frames transmitted along a link. The system may include a receiver to recognize a condition and to force a loss of synchronization condition on the link that will be converted by the receiver into a loss of light condition. The receiver may scan the transmitted stream of data frames for invalid data frames and introduce a code into the stream of data frames whenever an invalid data frame is detected.
