Queue Dynamics Of RED Gateways Under Large Number Of TCP Flows
White Papers 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.

Arguments In Favour Of Admission Control For TCP Flows
White Papers This paper advocates the use of admission control to limit the number of TCP flows on a network link to ensure that each has a minimal acceptable throughput. It demonstrates that, in the absence of such a control, the ineffective traffic due to the...

Throughput Enhancement For Uploading TCP Flows In IEEE 802.11 Wireless LANs
White Papers They blindly assume that the number of competing stations at the MAC layer is increasing as there are more stations with TCP flows, which is not true under the congested network condition. This paper reanalyzes the relationship between MAC...

TCP Optimized For Short Flows
White Papers TCP has been used very successfully for reliable communication for various data flows. One of the issues facing networks that support these data flows is Congestion. This is too conservative for short flows which require less than one round-trip...

The RTT Distribution Of TCP Flows In The Internet And Its Impact On TCP-Based Flow Control
White Papers The distribution of RTTs can dramatically affect not only the data rates realized by individual flows sharing a link but also the utilization of Internet links. It is well known that the performance of a TCP flow is affected by its Round-Trip Time...

Interaction Between TCP And UDP Flows In Wireless Multi-Hop Ad Hoc Networks
White Papers The interaction between TCP and UDP flows are examined experimentally in simple scenarios, involving between three and four nodes. Early results show that TCP's congestion control is not tuned to wireless multi-hop settings, resulting in...

Attribution And Aggregation Of Network Flows For Security Analysis
White Papers This paper describes a network flow analyzer that is capable of attribution and aggregation of different flows into single activity events for the purposes of identifying suspicious and illegitimate behaviors.

Dealing With Short TCP Flows: A Survey Of Mice In Elephant Shoes
White Papers Short web transfers that dominate the Internet suffer from TCP's inadequate provisioning for short flows. This paper surveys ten proposals that attempt to solve one or more of the problems of short flows, and suggests general criteria to evaluate...

Characterizing Flows In Large Wireless Data Networks
White Papers This paper statistically characterizes both static flows and roaming flows in a large campus wireless network using a recently-collected trace. For static flows, it takes a two-tier approach to characterizing the flow arrivals, which results a...

The Cyclical Behavior Of Short-Term And Long-Term Job Flows
White Papers Looking at flows of workers and jobs has helped economists understand movements in aggregate employment. Rather than just looking at changes in the level of employment, attention has focused instead on the separate flows into and out of employment.

Is Reallocation Related To The Cycle?: A Look At Permanent And Temporary Job Flows
White Papers This paper decomposes plant level job flows into permanent and temporary components to answer this question, and finds that the permanent reallocation of jobs across plants accounts for approximately 30 percent of the cyclical fluctuations in...

Session Initiation Protocol (SIP) Public Switched Telephone Network (PSTN) Call Flows
White Papers This paper contains best current practice examples of Session Initiation Protocol (SIP) call flows showing interworking with the Public Switched Telephone Network (PSTN). Elements in these call flows include SIP User Agents, SIP Proxy Servers, and...

Testing SIP Call Flows Using XML Protocol Templates
White Papers This paper presents a novel test system for SIP based on the notion of XML Protocol Templates, of SIP call flows. A Session Initiation Protocol (SIP) Call Flow is a casual sequence of messages that is exchanged between interacting SIP entities.

The Effects Of Systemic Packet Loss On Aggregate TCP Flows
White Papers In the presence of congestion related losses, parallel flows steal bandwidth from other single stream flows. The use of parallel TCP connections to increase throughput for bulk transfers is common practice within the high performance computing...

Modelling TCP Flows Over An 802.11 Wireless LAN
White Papers This paper presents an analysis of the throughput of TCP flows transmitted over IEEE 802.11 wireless LAN connections, for the case when TCP flow control is restricted by the receivers' advertised windows.

Peer-to-Peer Behaviour Detection By TCP Flows Analysis
White Papers Main goal of this work is to use knowledge about TCP flows on routers (Cisco's NetFlow) to identify P2P users and flows. The use of Peer-to-Peer (P2P) applications is growing dramatically. It concerns applications like Gnutella, Kazaa or eDonkey.

Core-Stateless Fair Bandwidth Allocation For TCP Flows
White Papers The standard end-to-end flow control implemented by the TCP protocol is ill-suited when it comes to achieving fair bandwidth allocation among competing TCP flows. Indeed, the lack of feedback from intermediate nodes does not allow a TCP source to...

Impact Of Segments Aggregation On TCP Reno Flows In Optical Burst Switching Networks
White Papers 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...

Improving The Performance Of TCP In The Presence Of Interacting UDP Flows In Ad Hoc Networks
White Papers 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.
