tcp - ip flows in white papers

Efficiently and Fairly Allocating Bandwidth at a Highly Congested Link

White Paper This paper considers the problem efficiently and fairly allocating bandwidth at a highly congested link to a diverse set of flows, including TCP flows with various Round Trip Times... [10 Sep 2008]

A Gateway-Based Defense System for Distributed DoS Attacks in High-Speed Networks

White Paper These flows are marked as TCP flows, and use spoofed source identifiers to hide their identities. DDoS flooding attacks tend to establish large numbers of malicious traffic... [11 Jul 2008]

Improving XCP to Achieve Max-Min Fair Bandwidth Allocation

White Paper In a multi-bottleneck environment, XCP may achieve as low as 80% utilization at a bottleneck link and consequently some flows may only receive a small fraction of their max-min fair rates. TCP is shown... [08 Jul 2008]

Investigation of Ethernet Switches Behavior in Presence of Contending Flows at Very High-Speed

White Paper This paper examines the interactions between high speed Ethernet switches and TCP in high bandwidth delay product networks. Then the impact of these switches behaviors is studied on TCP protocols in Long... [04 Jul 2008]

A Square Root Formula for the Rate of Non-Persistent TCP Flows

White Paper The formula for the mean transmission rate is shown to boil down to the classical square root mean value formula for persistent flows when the average file size tends to infinity. Using fixed point methods, these... [03 Jul 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... [03 Jul 2008]

Congestion Control and an Analysis of TCP-Friendly Rate Control

White Paper To address the research in congestion control for UDP flows, datagram congestion control protocol (DCCP) and the congestion manager (CM) is discussed. This paper presents a history of congestion control research and an... [03 Jul 2008]

GPRSWeb: Optimizing the Web for GPRS Links

White Paper The paper examines why certain GPRS network characteristics interact badly with TCP to yield problems such as: link under-utilization for short-lived flows, ACK compression, poor loss recovery, and gross... [03 Jul 2008]

Towards Software-Based Signature Detection for Intrusion Prevention on the Network Card

White Paper TCP flows are first reconstructed before they are scanned with the Aho-Corasick algorithm. CardGuard is a signature detection system for intrusion detection and prevention that scans the entire payload... [21 May 2008]

SABUL: A Transport Protocol for Grid Computing

White Paper In order to remove the fairness bias between flows with different network delays, SABUL adjusts its sending rate at uniform intervals, instead of at intervals determined by round trip time. It uses UDP to transfer data... [10 Apr 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... [15 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... [15 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... [15 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... [15 Jan 2008]

Size-Based Scheduling to Improve the Performance of Short TCP Flows

White Paper The Internet today carries different types of traffic that have different service requirements. A large fraction of the traffic is either Web traffic requiring low response time or peer-to-peer traffic requiring high throughput. [15 Jan 2008]
