A Rate Controller for Long-Lived TCP Flows
White Paper In this paper a new mechanism for providing an assured rate to a long-lived TCP flow is proposed. The TRC seeks to achieve the requested rate by imposing well directed drops and (artificial) delays on the flow's packets. [14 Jan 2008]
Analyzing the Performance of TCP Flows in Packet Networks With LAS Schedulers
White Paper Also, Internet traffic exhibits a high variability in terms of the flow sizes: Most of the flows are short, while more than half of the bytes are carried by a few largest flows. Given these observations, the authors recommend Least Attained Service... [14 Jan 2008]
Size-Based Scheduling to Improve the Performance of Short TCP Flows
White Paper Under LAS, the next packet to be served is the one belonging to the flow that has received the least amount of service. The Internet today carries different types of traffic that have different service requirements. [14 Jan 2008]
An Integrated Packet/Flow Model for TCP Performance Analysis
White Paper Processor sharing (PS) models for TCP behavior nicely capture the bandwidth sharing and statistical multiplexing effect of TCP flows on the flow level. However, these 'rough' models do not provide insight into the impact of packet-level parameters... [14 Jan 2008]
Interaction of TCP Flows as Billiards
White Paper The aim of this paper is to analyze the performance of a large number of long lived TCP controlled flows sharing many routers (or links), from the knowledge of the network parameters (capacity, buffer size, topology) and of the characteristics of... [14 Jan 2008]
Support of Elastic TCP Traffic Over Broadband Geostationary Satellite Networks
White Paper It demonstrates that fundamental satellite access network capabilities provide enough flexibility for the provision of qualitative service differentiation for TCP flows over these networks without necessitating per-flow state at the MAC layer and... [14 Jan 2008]
Performance Evaluation of a New Adaptive Packet Marking Scheme for TCP Over DiffServ Networks
White Paper This paper presents an extensive performance evaluation of a new adaptive packet marking scheme, applied to a traffic scenario composed of TCP flows with different length. The proposed marking scheme is most efficient when applied to a scenario... [14 Jan 2008]
Inferring Path Sharing Based on Flow Level TCP Measurements
White Paper The premise is that flows that temporally overlap on congested resources will have correlated throughputs. This paper develops methods to infer path or bottleneck sharing among TCP flow classes based on flow level measurements available from... [14 Jan 2008]
A Multi-Level TCP Model With Heterogeneous RTTs
White Paper This paper studies TCP performance focusing on the mean flow transfer delay and the average number of concurrent flows in the system. This is done for a dynamic population of users, rather than a static number of permanent flows. [14 Jan 2008]
A New Three Color Marker for TCP Flows
White Paper The scheme provides protection of vulnerable packets in the TCP flows and adaptivity through "Probes" packets. The performance have been evaluated in a traffic scenario composed of TCP flows with different length. [14 Jan 2008]
Passive Estimation of TCP Round-Trip Times
White Paper The first technique is applicable to TCP caller-to-callee flows, and it is based on the 3-way handshake messages. The second technique is applicable to callee-to-caller flows, when the callee transfers a number of MSS segments to the caller, and it... [14 Jan 2008]
Revisiting the Fair Queueing Paradigm for End-to-End Congestion Control
White Paper These applications can often improve their own performance by not being TCP-friendly, which severely penalizes TCP flows. To be TCP-friendly, a source must behave in such a way as to achieve a bandwidth that is similar to the bandwidth obtained by... [14 Jan 2008]
Improving the Performance of TCP in the Presence of Interacting UDP Flows in Ad Hoc Networks
White Paper The problem addressed is that the throughput of TCP flows degrades severely in the presence of heavily loaded UDP flows. Backpressure improves the performance of TCP flows in the presence of heavy UDP flows. [14 Jan 2008]
TCP-Aware Packet Marking in Networks With DiffServ Support
White Paper The marking scheme can be implemented either in end systems or ingress routers, where the number of concurrent flows is limited, thus allowing per-flow management of packets. This paper shows the benefit of an alternative strategy in which packet... [14 Jan 2008]
TCP Model for Short Lived Flows
White Paper ACCORDING to studies, TCP, accounts for 95% of the total traffic volume, and 80% of the total number of flows in the Internet. Among the TCP flows, a large majority are short lived flows with the average and the median lengths no larger than 10 KB. [14 Jan 2008]
