A Rate Controller for Long-Lived TCP Flows
White Paper The choice of drop probability and delay is based on an analytical model of TCP sending behavior. 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... [14 Jan 2008]
TCP Throughput Analysis Under Transmission Error and Congestion Losses
White Paper This paper analyzes the performance of a large population of long lived TCP flows experiencing random packet losses due to both random transmission errors and congestion created by the sharing of a common tail drop bottleneck router. [14 Jan 2008]
Robust TCP Congestion Recovery
White Paper The performance of the proposed scheme is evaluated for scenarios with many TCP flows under the drop-tail and RED gateways in the presence of bursty packet losses. This paper presents a new robust TCP congestion-recovery scheme to handle bursty... [14 Jan 2008]
Fixed Point Approximations for TCP Behavior in Networks of Routers Implementing Heterogeneous Queue Management Policies
White Paper This paper uses fixed point methods to model the behavior of a population of TCP flows traversing a network of routers implementing either Drop Tail or the RED queue management policies. Once the average queue lengths are obtained, other metrics... [08 Jan 2008]
Performance Analysis of TCP/AQM Under Denial-of-Service Attacks
White Paper This paper investigates how the performance of TCP flows is affected by denial-of-service (DoS) attacks under the Drop Tail and various AQM schemes. However, the analysis usually assumed that routers and TCP flows are not under any network attacks. [08 Jan 2008]
Performance Measurements and Analysis of TCP Flows in a Differentiated Services WAN
White Paper Special attention was paid to the behaviour of competing TCP flows produced by users with different service level specifications. The target of the measurements was to collect precise information about the level of service, experienced by a user... [08 Jan 2008]
Impact of Drop Synchronisation on TCP Fairness in High Bandwidth-Delay Product Networks
White Paper This paper considers the performance of several well known high speed protocols in environments where individual flows experience different probabilities of seeing a drop in drop-tail buffers. The initial results suggest the properties of networks... [26 Dec 2007]
TCP Fairness for Uplink and Downlink Flows in WLANs
White Paper First, the paper discusses the unfairness problem of TCP flows due to different responses to data packet drop and TCP ACK packet drop at the AP. This paper proposes a dual queue based scheme in an Access Point (AP) for TCP fairness among uplink... [26 Dec 2007]
Analysis of the Competition Between Wired, DSL and Wireless TCP Flows in an Access Network
White Paper This paper analyzes the performance of a large population composed of several classes of long lived TCP flows experiencing packet losses due to random transmission errors and to congestion created by the sharing of a common tail-drop or AQM... [26 Dec 2007]
Intelligent Packet Discard Policies for Improved TCP Queue Management
White Paper The Queue State Deficit Round Robin algorithm (QSDRR) preferentially discards from long queues, but introduces hysteresis into the discard policy to minimize synchronization among TCP flows. QSDRR provides higher throughput and much better fairness... [19 Dec 2007]
TCP-Friendly Rate Control With Token Bucket for VoIP Congestion Control
White Paper TFRC has been proven to be fair when competing with TCP flows over congested links, but it lacks quality-of-service parameters to improve the performance of real-time traffic. TCP Friendly Rate Control (TFRC) is a congestion control algorithm that... [06 Nov 2007]
A Study of TCP Fairness in High-Speed Networks
White Paper Under the TCP congestion control regime, heterogeneous flows, i.e.flows with different Round-Trip Times (RTTs), that share the same bottleneck link will not attain equal portions of the available bandwidth. [30 Oct 2007]
TCP Vs. TCP: A Systematic Study of Adverse Impact of Short-Lived TCP Flows on Long-Lived TCP Flows
White Paper While earlier studies have pointed out that short-lived TCP flows (mice) may hurt long-lived TCP flows (elephants) in the long term, they provide insufficient insight for developing scenarios leading to drastic drop in throughputs of long-lived... [30 Oct 2007]
On Randomizing the Sending Times in TCP and Other Window Based Algorithms
White Paper Current implementations of TCP suffer from performance problems like bias against flows with higher Round Trip Times (RTTs), synchronization of windows, phase effects in flows and correlated losses leading to throughput degradations with Drop Tail... [29 Oct 2007]
