If the feedback can be obtained sooner at the source, the congestion handling can be more effective. The goal of this work is to expedite the feedback process and enhance the performance of the Internet under congestion. We motivate the need for the proposed schemes with the help of a simplified analytical model which evaluates the time to detect a packet loss through duplicate acknowledgements. We show that this time can be significant when the number of flows going through a router is large. We then present two schemes, Triple Packet Buffering on Congestion, and Triple Truncated Packets, that enables congestion information to be fed back to the source faster. This results in a faster response to congestion conditions, and a faster retransmission of discarded packets. With the help of simulation results, we show that the proposed schemes perform better than the standard implementation in a variety of network scenarios and achieve higher throughput and lower mean delay. This scheme also does not require any changes in the standard TCP protocols, but a simple (optional) modification at the routers.","PeriodicalId":302787,"journal":{"name":"Proceedings.

Sahoo","doi":"10.1109/ICCCN.2002.1043072","DOIUrl":"https://doi.org/10.1109/ICCCN.2002.1043072","url":null,"abstract":"Real-time applications such as Voice over IP, audio and video streaming require quality of service (QoS). Such applications are being executed over the public Internet. Since today's Internet largely supports best effort traffic, QoS routing in the best effort environment is required to support real-time applications. Some QoS routing uses source routing and others use flooding of some QoS attributes of the nodes. There were also some variants of the shortest path algorithm reported in the literature. But those algorithms require changes to the packet forwarding engine and logic for loop detection. We believe a better way of implementing QoS routing is to localize the QoS routing changes to the region where QoS has deteriorated and choose loop-free alternate paths. We present such an algorithm based on OSPF (open shortest path first) called the LSR algorithm. In the LSR algorithm, congestion notification is limited to neighbors of the congested node and the neighbors try to use alternate next hops to route packets. Alternate LSR next hop is chosen in such a way that it preserves the next hop property of OSPF routing which enables the LSR algorithm to avoid a loop. We present three such methods to choose an alternate LSR next hop and prove that these methods provide loop-free routing. Our simulation results based on the three methods show that on average the LSR algorithm performs better than the OSPF algorithm in terms of delay and jitter.","PeriodicalId":302787,"journal":{"name":"Proceedings.
