Numerous studies have shown that packet reordering is common, especially in networks where there is high degree of parallelism and different link speeds. Reordering of packets decrease the TCP performance of a network, mainly because it leads to overestimation of the congestion in the network. In this paper, we analyze the performance of networks when reordering of packets occur. We propose a p...

Numerous studies have shown that packet reordering is common, especially in satellite networks where there are regular handoffs occurring between neighboring satellites. Reordering of packets decreases the TCP performance of a network, mainly because it leads to overestimation of the congestion of the network. We consider satellite networks and analyze the performance of such networks when reor...

Multipath routing gains clear network performance advantages for data streaming in networked systems with high path diversity. The level of packet reordering, however, becomes higher: distant packets are reordered, the application performance is reduced due to head-of-line blocking at the destination, and a large resequencing buffer is needed for sorting incoming packets. In this paper, we stud...

Numerous studies have shown that packet reordering is common, especially in 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 packets oc...

The congestion control mechanisms in the standardized Transmission Control Protocol (TCP) may misinterpret packet reordering as congestive loss, leading to spurious congestion response and under-utilization of network capacity. Therefore, many TCP enhancements have been proposed to better differentiate between packet reordering and congestive loss, in order to enhance the reordering robustness ...

TCP performs poorly in networks with serious packet reordering. Processing reordered packets in the TCP-layer is costly and inefficient, involving interaction of the sender and receiver. Motivated by the interrupt coalescing mechanism that delivers packets upward for protocol processing in blocks, we propose a new strategy, Sorting Reordered Packets with Interrupt Coalescing (SRPIC), to reduce ...

This paper studies the effect of out-of-order packets on the MPTCP performance when using different access technologies, modelled to represent path diversity in terms of delay and reliability. The study identifies trade-offs between different CC algorithms in terms of aggregate throughput gain when different packet reordering recovery solutions being implemented. Our analysis shows that TCP-DOO...

Future wireless access networks will be heterogeneous wireless network (HWN) environment which consists of various wireless technologies including universal mobile telecommunications system (UMTS) networks and wireless local area networks (WLAN). They are used together through vertical handover (VHO) to ensure global mobility and service continuity. The mobile stream control transmission protoc...

In this work, we performed variety of tests to see the effects of network loads and latency in multiplayer online games. We applied hierarchical load testing architecture using large scale virtual clients to find out the bottlenecks of the game servers. We also investigated the effect of latency on multiplayer online games. We controlled network game packets (i.e. packet delay, packet drop rate...
