Improving XCP to Achieve Max-Min Fair Bandwidth Allocation
White Paper The eXplicit Control Protocol (XCP) is a new and promising protocol that outperforms TCP in terms of efficiency, stability, queue size, and convergence speed. In a multi-bottleneck environment, XCP may achieve as low as 80% utilization at a... [08 Jul 2008]
Queue Dynamics of RED Gateways Under Large Number of TCP Flows
White Paper As the number of competing flows becomes large, the queue behavior of RED can be described by a two-dimensional recursion. This paper considers a stochastic model of a RED gateway under competing TCP-like sources sharing the capacity. [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]
Limit Behavior of ECN/RED Gateways Under a Large Number of TCP Flows
White Paper As the number of competing flows becomes large, the queue behavior at the gateway can be described by a two-dimensional recursion and the throughput behavior of individual TCP flows becomes asymptotically independent. [14 Jan 2008]
Queue Delay Estimation and Its Application to TCP Vegas
White Paper It also proposes an estimation algorithm for the marking queue delay in TCP data traffic by using the Kalman filter. With this, the marking queue delay is defined. In order to do this, the paper investigates the maximum round-trip time achievable... [14 Jan 2008]
Passive Estimation of TCP Round-Trip Times
White Paper Such an RTT distribution is important in buffer provisioning, configuration of active queue management, and detection of congestion unresponsive traffic. The first technique is applicable to TCP caller-to-callee flows, and it is based on the 3-way... [14 Jan 2008]
An Implementation of a Service Class Providing Assured TCP Rates Within the AQUILA Framework
White Paper The service class adds admission control functionality and a model for multi-RED queue management to the token bucket marker. This paper investigates an attempt to establish a QoS class that supports long-lived, bulk-data TCP flows that require a... [14 Jan 2008]
Testing Fast TCP Over Abilene
White Paper Fast TCP is an advanced version of TCP congestion control that uses delay, in addition to loss, as its source of knowledge about the state of congestion at the bottleneck, and, therefore, has a potential for using the network bottleneck link... [14 Jan 2008]
A Square Root Formula for the Rate of Non-Persistent TCP Flows
White Paper Using fixed point methods, these formulae can be applied to predict bandwidth sharing among competing HTTP flows subject to Active Queue Management. The formula for the mean transmission rate is shown to boil down to the classical square root mean... [14 Jan 2008]
Impact of Precedence Enabled Per Hop Behaviors on TCP Flows
White Paper The approach to this duality is to enhance Active Queue Management (AQM) techniques to provide Precedence and Preemption (P&P) capabilities and rely upon standard, well studied QoS Per Hop Behavior (PHB), e.g. [08 Jan 2008]
Performance Analysis of TCP/AQM Under Denial-of-Service Attacks
White Paper The interaction between TCP and various Active Queue Management (AQM) algorithms has been extensively analyzed for the last few years. However, the analysis usually assumed that routers and TCP flows are not under any network attacks. [08 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]
TCP Synchronisation Effect in TCP New Reno and TCP Hybla
White Paper The synchronisation effect is caused by the relation between the round trip time (RTT) of packets of certain flows and the moment when a new slot comes available at a saturated DropTail queue (from which multiple flows make use of). [08 Jan 2008]
An Analytical Model of a New Packet Marking Algorithm for TCP Flows
White Paper Preliminary simulative results show quite accurate predictions for throughput and average queue occupancy. As a consequence, packet marking schemes can be devised to differentiate packets belonging to a same TCP flow, with the goal of improving the... [26 Dec 2007]
TCP Fairness for Uplink and Downlink Flows in WLANs
White Paper This paper proposes a dual queue based scheme in an Access Point (AP) for TCP fairness among uplink flows and downlink flows. The dual queue scheme is simple and effective for resolving the TCP unfairness problem. [26 Dec 2007]
