RSS tcp - ip flowsEfficient 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]
Analyzing the Performance of TCP Flows in Packet Networks With LAS Schedulers
White Paper 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]
Size-Based Scheduling to Improve the Performance of Short TCP Flows
White Paper 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]
Improving the Performance of TCP in the Presence of Interacting UDP Flows in Ad Hoc Networks
White Paper 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]
An Implementation of a Service Class Providing Assured TCP Rates Within the AQUILA Framework
White Paper 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]
Support of Elastic TCP Traffic Over Broadband Geostationary Satellite Networks
White Paper 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]
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. 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]
Low-Rate TCP-Targeted Denial of Service Attacks
White Paper 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]
On the Performance of TCP Loss Recovery Mechanisms
White Paper 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]
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]
Passive Estimation of TCP Round-Trip Times
White Paper The first technique is applicable to TCP caller-to-callee flows, and it is based on the 3-way handshake messages. The second technique is applicable to callee-to-caller flows, when the callee transfers a number of MSS segments to the caller, and it... [14 Jan 2008]
A Multi-Level TCP Model With Heterogeneous RTTs
White Paper This paper studies TCP performance focusing on the mean flow transfer delay and the average number of concurrent flows in the system. This is done for a dynamic population of users, rather than a static number of permanent flows. [14 Jan 2008]
An Integrated Packet/Flow Model for TCP Performance Analysis
White Paper Processor sharing (PS) models for TCP behavior nicely capture the bandwidth sharing and statistical multiplexing effect of TCP flows on the flow level. However, these 'rough' models do not provide insight into the impact of packet-level parameters... [14 Jan 2008]
ATFRC: Adaptive TCP Friendly Rate Control Protocol
White Paper TFRC (TCP Friendly Rate Control) is a rate-based congestion control protocol for non-TCP flows. TFRC controls the sending rate by using the TCP throughput equation considering the triple duplicate ACKs and the timeouts. [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]
