Abstract:
1. A method for providing a transport protocol within a lossy network, comprising: receiving multiple packets, wherein each of the received packets includes a header and an associated sequence number, wherein the header includes a congestion alleviation indication and an impending congestion indication; monitoring the network for congestion caused by the received packets; marking the header of some of the packets with an impending congestion indication based on the outcome of the monitoring; transmitting the monitored multiple packets through the lossy network; returning acknowledgements of receipt for each of the transmitted packets, based on the sequence number associated with each of the packets, and any associated marked impending congestion indication and the congestion alleviation indication; monitoring each of the received acknowledgements for the sequence number and the marked impending congestion indication associated with each of the received packets; and invoking a congestion control mechanism to control a congestion window size which regulates the transmitted packets based on the monitoring of the acknowledgements and the marked impending congestion indication, and further marking the header with a congestion alleviation indication.
