More practical work is needed to demonstrate how this protocol Options", to determine if the existing network path and endnode supports The authors say "These checks can be done using simple TCP and IP I specifically didn't think they were being realistic when The description provided on how this technology would be introduced into The one section that I thought was particularly weak in the paper was Performed using aggregated information and the feed into the fairnessĬalculation to determine modifications to individual packets. The decomposition of the calculation of the feedback The main contribution of the paper is the analysis and design of theįeedback control. Receiving endnode will attach this header into the acknowledgementĪllowing the sender to modify its congestion window appropriately. Packet with this feedback as it flows towards its receiving endnode. Periodically calculate adjustments to the congestion window and update a In an XCP enabled channel the protocol requires each send to add anĪdditional packet header (called a congestion header) containing itsĬurrent congestion window and round-trip-time. Level of coordination can result in more efficient changes in senderīehavior in turn resulting in improvements in bandwidth utilization andįewer dropped packet due to congestion all while enabling a fair use of The authors thenĪttempt to show through testing and measurement that this increased The protocol calledĮxplicit Control Protocol (XCP) proposes to increase the level ofĬoordination between sending logic on endnodes and routers by addingĪdditional control information in each TCP packet. New congestion control protocol for TCP networks. It was submitted to SIGCOMM in August of 2002. Product Networks" was written by a number of researchers from MIT andīerkley.
