Robustness to Packet Reordering in High-speed Networks
نویسندگان
چکیده
In this paper we investigate the impact of packet reordering on the performance of high-speed protocols. Our results show that even small fraction of packet reordering can severely impair the performance of these protocols. We then investigate the benefits of using delayed congestion response (TCP-DCR) with the high-speed protocols. Our results indicate that the benefits in terms of avoiding performance degradation is significant, even at very high levels of packet reordering. In the absence of any packet reordering, the protocol behavior in terms of fairness among competing flows or impact on bottleneck link drop rates remains unmodified.

Packet reordering in high-speed networks and its impact on high-speed TCP variants
Several recent Internet measurement studies show that the higher the packet sending rate, the higher the packet-reordering probability. This implies that recently proposed high-speed TCP variants are more likely to experience packet reordering than regular TCP in high-speed networks, since they are designed to achieve much higher throughput than regular TCP in these networks. In this paper, we ...
متن کاملImproving the Performance of TCP in the Case of Packet Reordering
Numerous studies have shown that packet reordering is common, especially in high speed networks where there is high degree of parallelism and different link speeds. Reordering of packets decreases the TCP performance of a network, mainly because it leads to overestimation of the congestion of the network. We consider wired networks and analyze the performance of such networks when reordering of...

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...
