Abstract
Standard TCP faces some performance limitations in very high speed wide
area networks, mainly due to a long end-to-end feedback loop and a conser-
vative behaviour with respect to congestion. Many TCP variants have been
proposed to overcome these limitations. However, TCP is a complex protocol
with many user-configurable parameters and a range of different implementa-
tions. It is then important to define measurement methods so that the transport
services and protocols can evolve guided by scientific principles and compared
quantitatively. The goal of this report is to present some steps towards a user-
oriented benchmark, called ITB, for high speed transport protocols compari-
son. We first present and analyse some results reported in the literature. From
this study we identify classes of ...
