Date of Defense 2011-07-06 Availability unrestricted Abstract This paper is broken down into two parts:(1) discussion of current formulas that are used to calculatesynchronized loss rates among concurrent TCP flows with the results of those equations on flows running
through a bottleneck on a high speed emulated network and (2)steps to create revised forms of these
equations that are more accurate and give a more reasonable estimation without having the shortcomings
of the current equations.
This paper brings to light three equations that were previously proposed and were used in published
research projects along with their strengths and shortcomings. Through the study of these equations
a series of newly revised forms of these algorithms will be introduced that take into account their
predecessors’ pitfalls and gives a more affective and useful result under any set of networking conditions
including large numbers of concurrent flows, multiple variations of TCP, and variations of receiving queue
sizes among others. In this paper we will prove, through logical analysis of the equations structure,
definition, and results they provide of network emulations on the CRON testbed, that these modifications
to the existing formulas are necessary in order to provide a metric that depicts an accurate view of the
synchronization loss rate of a given network.
