usually in the form of parallel processing with parallel multi-processor systems are designed .for this reason irregular flow may occur with packages. when you're tired and it all comes out in his np (network processors)  system, reset depending on network performance is negatively affected and we delayed to do this, the design of processors working in parallel packet transmission by avoid...

The increase in link speeds, increased parallelism within routers and switches, QoS support and load balancing among links, all point to future networks with increased packet reordering. Unchecked, packet reordering will have a significant detrimental effect on the end-to-end performance, while resources required for dealing with packet reordering at routers and end-nodes will grow considerably...

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 ...

The Internet is experiencing an exponential growth in users and network traffic. As the Internet grows larger and larger, the performance of the network is subjected to severe performance degrading issues such as congestion in the network, link failures, corruption of packets and reordering of packets. In this thesis, we examine the problem of packet reordering in networks and how reordering of...

Abstract – Packet reordering is an inevitable phenomenon on the Internet. An ideal metric for packet reordering should capture reordering accurately, provide insight into nature of reordering, and help in evalu...

Packet reordering adversely affects the behavior and performance of the Transmission Control Protocol (TCP), the predominant transport protocol on today's Internet. This shortcoming is becoming a problem of increasing importance, as packet reordering is on the rise on some Internet paths. The issue at the heart of TCP's poor performance in the presence of packet reordering is its inability to d...

This document presents two improved metrics for packet reordering, namely, Reorder Density (RD) and Reorder Buffer-occupancy Density (RBD). A threshold is used to clearly define when a packet is considered lost, to bound computational complexity at O(N), and to keep the memory requirement for evaluation independent of N, where N is the length of the packet sequence. RD is a comprehensive metric...

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 pe...
