Abstract: Traffic between a first device and a second device across a plurality of communication lanes of a communication link is stalled. A first device side of the communication lane is powered-down on at least one of the plurality of communication lanes to deactivate the at least one communication lane. A power-down request is sent from the first device to the second device to power-down a second device-side of the at least one communication lane. Traffic between the first device and the second device is restarted over the active communication lanes.

Abstract: Various systems and methods for using credits to determine cable length are described herein. A number of available credits is determined at a transmitter, the credits being received at the transmitter from a receiver, and each of the credits being used for the transmitter to transmit a packet to the receiver. An average number of credits for a period is determined. The cable length between the transmitter and the receiver is determined based on the average number of credits for the period.

Abstract: Techniques are provided to allow for efficient data packing under certain coding schemes, e.g., when an enhanced 64/66 encoding scheme is employed. The traditional 64/66 encoding scheme uses idle bytes to pad packets to obtain a packet of fixed size, thereby adding idle overhead to transmitted packets. Accordingly, the techniques eliminate padding bytes and provide for receiving packets by way of a first data link at forwarding device. The packets are transmitted using a scheme that pads the packets to achieve a predetermined packet length. The padding is removed from the received packets to obtain unpadded packets. Data segments of the unpadded packets are concatenated for forwarding in a continuous data stream with a packet delimiter separating each of the unpadded packets. The continuous data stream is encoded using enhanced physical coding sub layer for forwarding over a second data link.
