Systems and methods are provided for scheduling the transmission of data in a datapath. A source node can send a registration request indicating its preferred sending time for data transmission. Intermediate nodes can determine if there are overlaps in timeslot reservations and adjust, and schedule, the requested preferred sending time accordingly.

Distributed scheduling algorithm for CPRI over ethernet

Method and computing devices for enforcing packet order based on packet marking. Upon occurrence of a link failure, a first device reallocates traffic initially forwarded through the failed link to an alternative link and marks the reallocated traffic with a first flag. Upon recovery of the failed link, the reallocated traffic is forwarded again through the recovered link and marked with a second flag different from the first flag. A second device calculates a reference inter-packet time for received traffic marked with the first flag. For received traffic marked with the second flag, the second device calculates a current inter-packet time. The current inter-packet time is compared with the reference inter-packet time, to determine if the traffic marked with the second flag shall be forwarded immediately or if the forwarding shall be delayed.

Switch fabric in routers require tight characteristics in term of packet loss, fairness in bandwidth allocation and low latency for high-priority traffic. Such attributes have been resolved using specialized switch devices, but with the emergence of Data Center Bridging, the possibility of using commodity Ethernet switches to build switch fabric in routers is considered. Systems and methods are provided for estimating congestion associated with a network path in accordance with the variation in average delay experienced by samples of packets.
