Abstract: Technologies for timestamping data packets with forward error correction is disclosed. Alignment markers may be inserted in a data stream in order to assist with synchronization on the receiving end. After insertion of the alignment markers, a start of frame delimiter or other trigger may be detected, triggering a timestamp corresponding to the start of frame delimiter or other trigger. The data and the timestamp are sent to a remote compute device, which may timestamp the data before removing the alignment markers. With this approach, insertion of the alignment markers does not lead to a deviation in the timestamp of the sending compute device or the receiving compute device.

Abstract: Technologies for robust data transmission include a network port logic having a physical coding sublayer (PCS). The PCS may transmit a series of rapid alignment markers (RAMs) to a link partner, with each RAM indicative of a counter value. The PCS transitions to a sleep state if the counter value equals two and a low power idle (LPI) command is set by an upper-layer client. The PCS transitions to an active state if the counter value equals one and the LPI command is not set. The PCS may receive a low power idle symbol (LI) from the link partner and start a guard timer in response to receipt of the LI symbol. The PCS transitions to a sleep state if the guard timer expires and transitions to the active state if data other than LI is received prior to expiration of the guard timer. Other embodiments are described and claimed.

Abstract: In a transceiver, the accuracy of a packet time stamp can be improved by compensating for errors introduced by processing of the packet. A received packet can be received via multiple lanes. A packet time stamp can be measured using a start of frame delimiter (SFD). A last arriving lane can be used to provide a recovered clock signal. A phase offset between the recovered clock signal and the system clock of the transceiver can be used to adjust the time stamp. A position of the SFD within a data block can be used to adjust the time stamp. A position of the data block within a combined group of data blocks can be used to adjust the time stamp. Also, a serializer-deserializer delay associated with the last arriving lane can be used to adjust the time stamp.
