Analysis of Multiple Flows using Different High Speed TCP protocols on a General Network [article]

Sudheer Poojary, Vinod Sharma
2016 arXiv   pre-print
We develop analytical tools for performance analysis of multiple TCP flows (which could be using TCP CUBIC, TCP Compound, TCP New Reno) passing through a multi-hop network.  ...  We then consider two techniques to compute steady state throughput for different TCP flows in a multi-hop network. In the first technique, we approximate the queues as M/G/1 queues.  ...  There are a number of simulation and experimental evaluations for performance analysis of these TCP variants over different network topologies.  ...

Periodic dynamics in queuing networks

Tommaso Addabbo, Ljupco Kocarev
2009 Chaos, Solitons & Fractals  
This paper deals with state-dependent open Markovian (or exponential) queuing networks, for which arrival and service rates, as well as routing probabilities, may depend on the queue lengths.  ...  For a network of this kind, following Mandelbaum and Pats, we provide a formal definition of its associated fluid model, and we focus on the relationships which may occur between the network stochastic  ...  Williams for her help and assistance, as well as for her valuable insights and comments.  ...

2019 arXiv   pre-print
Queueing networks are systems of theoretical interest that find widespread use in the performance evaluation of interconnected resources.  ...  In comparison to counterpart models in genetics or mathematical biology, the stochastic (jump) processes induced by queueing networks have distinctive coupling and synchronization properties.  ...  We offer evidence of the procedure providing a flexible and scalable transient approach for the estimation of resource demands.  ...
