Fluid-based Analysis of TCP Flows in a Scale-Free Network
Yusuke Sakumoto, Hiroyuki Ohsaki, Makoto Imase (Osaka Univ.) IN2010-36
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we derive distributions of throughput, round-trip time,
and packet loss probability of TCP flows in a scale-free network~(BA
(B\'{a}rabasi Albert) tree). Different from random networks, the
connecting probability between nodes is dependent on their node
degrees in scale-free networks. Hence, scale-free networks are
generally difficult to analyze. Fekete {\em et al.} have derived the
average throughput of TCP flows in a scale-free network by limiting
the network topology to a class of scale-free networks~(i.e., BA
tree). Not only the average throughput of TCP flows but also
distributions of their performance metrics are important for design
and control of an information network. In this paper, we therefore
derive distributions of throughput, round-trip time, and packet loss
probability of TCP flows in a scale-free network using an approximate
analysis. Similarly to Fekete's analysis, we use the BA tree as the
network topology. Dynamics of TCP flows and routers are modeled with
fluid-flow approximation.
