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 flows to congest network. The paper aims at protecting TCP friendly traffic... [11 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 unfairness between competing flows. [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 of packets for suspicious patterns and is... [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 and TCP to return control... [10 Apr 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 formulae can be applied to predict... [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]
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 mechanism is called TCP rate controller (TRC) and operates as a traffic conditioner at the edge of a network. [14 Jan 2008]
Efficient Queue Management for TCP Flows
White Paper Packets in the Internet can experience large queueing delays during busy periods. Backbone routers are generally engineered to have large buffers, in which packets may wait as long as half a second (assuming FIFO service, longer otherwise). [14 Jan 2008]
Jointly Coordinating ECN and TCP for Rapid Adaptation to Varying Bandwidth
White Paper This paper explores the design of a rapidly-reactive congestion control framework, where the ECN-aware best-effort flows aggressively go after any unused capacity. By making routers mark packets in a much more aggressive manner, the authors are... [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]
Queueing Network Model of Short-Lived TCP Flows With Mixed Wired and Wireless Access Links
White Paper This paper presents an analytical model, based on a Fixed Point Approximation (FPA) solution, that can be used to derive the performance of different sets of TCP connections that share, and compete for, a common resource, typically a link and its... [14 Jan 2008]
Size-Based Scheduling to Improve the Performance of Short TCP Flows
White Paper Meeting both performance requirements in a network where routers use droptail or RED for buffer management and FIFO as service policy is an elusive goal. It is therefore worthwhile to investigate alternative scheduling and buffer management... [14 Jan 2008]
A Hybrid Systems Framework for TCP Congestion Control: A Theoretical Model and Its Simulation-Based Validation
White Paper This paper makes use of hybrid systems to model the transient and steady-state behavior of multiple TCP flows that share a single common bottleneck link. For the past decade, TCP congestion control mechanisms have been under the scrutiny of the... [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. This paper proposes a recursive, analytical model to predict the TCP performance in terms of completion time for short... [14 Jan 2008]
Differentiation Between Short and Long TCP Flows: Predictability of the Response Time
White Paper Internet measurements show that a small number of large TCP flows are responsible for the largest amount of data transferred, whereas most of the TCP sessions are made up of few packets. This paper proposes a packet level stateless; threshold based... [14 Jan 2008]
