Abstract: The technology is generally directed to reordering packets received by a network to reduce the unfairness in transmitting and receiving data. The packets may be reordered based on a timestamp appended to the packet. The timestamp may correspond to a time when the sender loses control of the packet and the receiving network gains control. A packet reorder structure may receive the packets with the appended timestamps during a sample interval. The packet reorder structure may compare the timestamp to a time interval for a plurality of timeslots. The packets may be reordered based on the timeslot the packet is allocated to. In some examples, the duration of the timeslot may be dynamically adjusted such that the number of out of order packets received during the sample interval corresponds to a threshold.

Abstract: The technology is generally directed to programming delays in hardware already existing within fiber networks to reduce the unfairness in transmitting and receiving data. The delays may be programmed in the optics hardware after the deployment of the network. The delays may be determined based on the time it takes the networking switch to replicate data to be transmitted and/or the length of the cables. According to some examples, the delays may be programmed at either or both the egress and ingress optics hardware of a cable. The programmable delay reduces the unfairness of one destination, or end user, receiving data before another destination when the information is intended to be received synchronously.
