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. A rate-based congestion control that tunes the inter... [10 Apr 2008]
Improving the Convergence Time of HighSpeed TCP
White Paper That is, it takes a long time for a new HSTCP flow to achieve fair bandwidth allocation if the existing HSTCP flows have large congestion windows. It is reported that TCP does not perform well in high-speed and long-distance networks. [15 Jan 2008]
Improving the Performance of TCP on Guaranteed Bandwidth Connections
White Paper The congestion control mechanisms like slow start and congestion avoidance have to be revised in the context of guaranteed services, where no congestions occur for special flows. Nevertheless, TCP connections often cannot fully exploit the reserved... [15 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... [15 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. Today, the dominant paradigm for congestion control in the Internet is based on the notion of TCP-friendliness. [15 Jan 2008]
Optimizing Aggregate Throughput of Upstream TCP Flows Over IEEE 802.11 Wireless LANS
White Paper This paper via analysis and simulation revisits the interaction between MAC contention and TCP congestion control over IEEE 802.11 WLANs, misled in the previous efforts. Thus, the paper proposes a new scheme called TCP ACK Priority (TAP) in which... [27 Dec 2007]
An Experimental Investigation of the Congestion Control Used by Skype VoIP
White Paper The paper has found that Skype flows are somewhat elastic, i.e.they employ some sort of congestion control when sharing the bandwidth with unresponsive flows, but are inelastic in the presence of classic TCP responsive flows, which provokes... [21 Dec 2007]
Adaptive Aggregated Aggressiveness Control on Parallel TCP Flows Using Competition Detection
White Paper This paper presents a competition detection mechanism for parallel TCP flows and uses this to propose a new parallel TCP congestion control scheme called Adaptive TCP-P (A-TCP-P). A-TCP-P automatically controls the aggregated aggressiveness of... [20 Dec 2007]
TCP-Like Congestion Control for Layered Multicast Data Transfer
White Paper The algorithm behaves similarly to TCP congestion control algorithms, and shares bandwidth fairly with other instances of the protocol and with TCP flows. This paper presents a novel congestion control algorithm suitable for use with cumulative... [20 Dec 2007]
A Case for TCP-Friendly Admission Control
White Paper Admission control has been shown to be a preferred alternative to TCP-friendly congestion control for inelastic flows in heterogeneous networks shared by elastic and inelastic traffic. A totally aggressive version would admit an inelastic flow even... [20 Dec 2007]
LTCP: Improving the Performance of TCP in Highspeed Networks
White Paper LTCP modifies the TCP flow to behave as a collection of virtual flows to achieve more efficient bandwidth probing. The number of virtual flows emulated is determined based on the dynamic network conditions by using the concept of virtual layers... [20 Dec 2007]
End-to-end Fairness for TCP Traffic in 802.11e Wireless Mesh Networks Without Coordination
White Paper First it shows that TCP ACK packets have to be prioritised using IEEE 802.11e since otherwise congestion losses of ACK packets cause unpredictable performance. In terms of flow level fairness however, this paper highlights that gross unfairness can... [20 Dec 2007]
Modeling the Effect of Short-Term Rate Variations on TCP-Friendly Congestion Control Behavior
White Paper However, when flows compete for bandwidth, they may not have the same perception of congestion. To maintain stability of the Internet, flows other than TCP must be "friendly" to TCP flows, or share network bandwidth fairly with TCP traffic. [06 Dec 2007]
TCP Optimized for Short Flows
White Paper This paper proposes a technique to improve TCP's Congestion Control algorithms' ability to overcome the slow-start problem for short flows of data while retaining TCP Congestion Control semantics for longer flows. [06 Dec 2007]
The Effects of Systemic Packet Loss on Aggregate TCP Flows
White Paper In the presence of congestion related losses, parallel flows steal bandwidth from other single stream flows. This paper considers the impact of systemic non-congestion related packet loss on the effectiveness, fairness, and efficiency of parallel... [06 Dec 2007]
