P2P-IPTV World: Measure to better discover

Triple-play (high-speed Internet, Telephone, and TV) in which IPTV is an important factor is now largely offered by many Internet Service Providers (ISP). But being a combined business model, it has some limits because of price and equipment requirements. By that reason, P2P-IPTV appeared as a competitor. With low price and does not require deluxe configuration at end-user computer, P2P-IPTV becomes more popular in recent years. In this paper, we present a passive measurement in order to differentiate countries in the P2P-IPTV world in three aspects: the number of users, the contribution in terms of upload/download amount and the proximity logic. Moreover, in this study, we also analyze the number of ports used by one peer in the P2P network as well as the distribution of the default TTL. The results achieved help us to propose a heuristic method so that we could possibly detect the existence of NAT (Network Address Translation) in the P2P-IPTV systems.
