This paper is broken down into two parts:(1) discussion of current formulas that are used to calculate

synchronized 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

predecessorsí 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.
