  Over the last years many technological advances were introduced in Internet
television to meet user needs and expectations. However due to an overwhelming
bandwidth requirements traditional IP-based television service based on simple
client-server approach remains restricted to small group of clients. In such
situation the use of the peer-to-peer overlay paradigm to deliver live
television on the Internet is gaining increasing attention. Unfortunately the
current Internet infrastructure provides only best effort services for this
kind of applications and do not offer quality of service.
  This paper is a research proposition which presents potential solutions for
efficient IPTV streaming over P2P networks. We assume that the solutions will
not directly modify existing P2P IPTV protocols but rather will be dedicated
for a network engineer or an Internet service provider which will be able to
introduce and configure the proposed mechanisms in network routers.
