whitepaper 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]
whitepaper This paper studies the Optical Burst Switching (OBS) paradigm for the support of the TCP flows in an All Optical Network (AON). It analyzes the TCP send rate, i.e.the amount of data sent per time unit, taking into account of the burst assembly...
[14 Jan 2008]
whitepaper 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]
whitepaper 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]
whitepaper The aim of this paper is to analyze the performance of a large number of long lived TCP controlled flows sharing many routers (or links), from the knowledge of the network parameters (capacity, buffer size, topology) and of the characteristics of...
[14 Jan 2008]
whitepaper 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. Several authors have invoked this property to suggest the use...
[14 Jan 2008]
whitepaper 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]
whitepaper 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]
whitepaper 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]
whitepaper 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]
whitepaper 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]
whitepaper Also, Internet traffic exhibits a high variability in terms of the flow sizes: Most of the flows are short, while more than half of the bytes are carried by a few largest flows. Given these observations, the authors recommend Least Attained Service...
[14 Jan 2008]
whitepaper 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.
[14 Jan 2008]
whitepaper The problem addressed is that the throughput of TCP flows degrades severely in the presence of heavily loaded UDP flows. Backpressure improves the performance of TCP flows in the presence of heavy UDP flows.
[14 Jan 2008]
whitepaper ACCORDING to studies, TCP, accounts for 95% of the total traffic volume, and 80% of the total number of flows in the Internet. Among the TCP flows, a large majority are short lived flows with the average and the median lengths no larger than 10 KB.
[14 Jan 2008]
whitepaper This paper investigates mechanisms available at the satellite network for the provision of service differentiation to TCP flows. It demonstrates that fundamental satellite access network capabilities provide enough flexibility for the provision of...
[14 Jan 2008]
whitepaper This paper investigates an attempt to establish a QoS class that supports long-lived, bulk-data TCP flows that require a minimum rate from the network. The approach is based on a model for TCP flows subject to token bucket marking at the network...
[14 Jan 2008]
whitepaper While TCP's congestion control algorithm is highly robust to diverse network conditions, its implicit assumption of end-system cooperation results in a wellknown vulnerability to attack by high-rate non-responsive flows.
[14 Jan 2008]
whitepaper Moreover, 80% of the flows sent through the Internet are TCP flows. Among the applications that use TCP, the Web is the dominant one, comprising up to 75% of the bytes, 70% of the packets, and 75% of the flows considering both client and server...
[14 Jan 2008]
whitepaper 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...
