Abstract: In one embodiment, a retimer device includes a receiver to receive data from a first device via a data link, retimer circuitry to recover a clock phase from the received data, and prepare a new copy of the received data sampled by a clean clock based on the recovered clock phase, a transmitter to transmit the new copy to a second device via the data link, wherein the receiver is configured to receive an in-band standby signal from the first device having a given pattern in a physical layer of the signal, activate a power saving mode of the retimer device responsively to the standby signal having the given pattern in the physical layer of the standby signal, receive an in-band wakeup signal from the first device, and initiate an exit from the power saving mode to power up the retimer device responsively to the wakeup signal.

Abstract: In one embodiment, a multi-segment communication network system includes nodes connected via links, a first node including a first receiver and transmitter, and a second node including a second receiver and transmitter, wherein the first transmitter is to transmit a link training frame including a training pattern to the second receiver, which is to receive the link training frame, the second node is to find a tuning factor to which to tune the first transmitter responsively to the training pattern, and generate a request indicative of the found tuning factor, the second transmitter is to send the request in the link training frame via a plurality of the links to the first receiver, the first receiver is to receive the request, and the first node is to tune at least one parameter of the first transmitter based on the tuning factor indicated in the request.

Abstract: A network element includes at least one communication port and a processor. The communication port is configured to communicate with a peer communication port of a peer network element. The processor is configured to support a full-boot mode and a fast-boot mode, to establish, by negotiation with the peer network element, whether the fast-boot mode is supported both for the communication port and for the peer communication port, and, in response to finding that the fast-boot mode is supported both for the communication port and for the peer communication port, to coordinate with the peer network element a boot of the communication port and of the peer communication port, both using the fast-boot mode.

Abstract: Networking devices and optical communication systems are provided. In one example, a system is described to include a first physical coding sublayer (PCS) block that incorporates auto-negotiation information into a control block. The control block is transmitted to a second PCS block and the auto-negotiation information is used to enable negotiation between the first and the second PCS blocks.
