Congestion location detection: methodology, algorithm, and performance

Can an end-host running multiple TCP sessions

detect not just the occurrence, but also the location of congestion?

This paper answers this question through new analytic results on

the two underlying technical difficulties: synchronization effects

of loss and delay in TCP and distributed hypothesis testing using

only local loss and delay data, as well as practical algorithm

development and extensive simulations. It presents a Congestion

Location Detection algorithm that effectively allows an end host

to distributedly detect whether congestion happens in the local

access link or in more remote links. This further enables the

practical usage of low-priority congestion control protocols.
