Abstract-- Transmission of time-critical video traffic over the
networks with large end-to-end delays poses two main difficulties:
slow adaptation to changing network conditions and inability
of timely recovery from lost packets. Previously, we proposed a
proxy-based solution that enabled us to cope with these problems.
Our Internet experiments with a single proxy system showed
that the QoS delivered by interactive video applications could be
greatly improved by the Intermediate-Proxy approach. In multi-
proxy systems, however, the availability of a large number of
proxies throughout the Internet will bring the proxy selection
problem to the fore. This is an important problem since the
benefits of the intermediate-proxy approach can be best exploited
with a proper proxy selection. In this study, our goal is to
model the dynamics involved in the networks with proxies, and
investigate mathematical and practical proxy selection methods.
