On the interaction between TCP-like sources and throughput-efficient scheduling policies

Paolo Giaccone, Emilio Leonardi, Fabio Neri
2013 Performance evaluation (Print)  
We describe the average dynamics of both traffic sources and switch queues through a system of Delay Differential Equations (DDEs), whose properties are throughly analyzed.  ...  Our main finding is that AIMD sources and max-scalar switches co-exist well.  ...  round-trip time and the capacity of the queue.  ...

TCP Vegas Performance with Streaming Media

Sean Boyden, Anirban Mahanti, Carey Williamson
2007 Performance, Computing and Communications Conference (IPCCC), IEEE International  
We find that: 1) TCP is able to transport streaming media with good performance in a wide variety of scenarios; 2) TCP Vegas performs better than TCP NewReno in many cases; and 3) for viable media streams  ...  , both TCP variants need to achieve mean throughputs that are at least 1.5 times the encoding rate of the media objects being carried.  ...  Acknowledgments Financial support for this work was provided by the Natural Sciences and Engineering Research Council (NSERC) of Canada, as well as by the Informatics Circle of Research Excellence (iCORE  ...

Towards a Bufferless Optical Internet

Eric W. M. Wong, Lachlan L. H. Andrew, Tony Cui, Bill Moran, Andrew Zalesky, Rodney S. Tucker, Moshe Zukerman
2009 Journal of Lightwave Technology  
With sufficient wavelengths, high throughput can be obtained with a buffer of one packet per channel; furthermore, there may be situations where an entirely bufferless optical packet switching (OPS) will  ...  This analytical method provides accurate and scalable approximations of throughput and packet loss rate that can be used as part of a tool for DWDM network and switch design.  ...  Here, B is the size of the buffer, C O is the capacity of the bottleneck link, and RT T is the average round trip time of the TCP flows running in the bottleneck link (where "round trip time" is the time  ...

Feedback control for QoS of mixed traffic in communication networks

Hyung Seok Kim, Soo Young Shin, Wook Hyun Kwon
2004 Control Engineering Practice  
Mathematical models are suggested to describe networks including real-time traffic (RTT) and non-real-time traffic (NRT) sources.  ...  DBCM is evaluated in terms of punctuality rate and packet loss ratio in the network with an example of mixed traffic.  ...  NRT input rate is determined on the basis of available bandwidth remained by RTT control. NRT sources share a destination and have round trip delay 2 and 3, respectively.  ...

Discussion

K. Briggs
2008 Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences  
For example, it is much harder to avoid the round-trip time bias of current transport protocols.  ...  Drivers would undoubtedly react to these changes and adjust their trips, by changing trip times or routes. Figuring out what these changes might be is also called the 'trip assignment' problem.  ...

Active Queue Management: A Survey

Richelle Adams
2013 IEEE Communications Surveys and Tutorials  
In this survey we discuss the general attributes of AQM schemes, and the design approaches taken such as heuristic, control-theoretic and deterministic optimization.  ...  This survey attempts to travel the trajectory of AQM research from 1993 with the first algorithm, Random Early Detection (RED), to current work in 2011.  ...  For example, TCP flows with shorter round-trip times usually obtain more bandwidth than those with longer round-trip times.  ...
