Nowadays the popularity of multimedia content distribution over Internet is increasing. Providing live stream or video on demand services over Internet is a challenging problem for providers because:

  • video streaming is an high bandwidth demand service
  • there are scalability issues due to a large number of clients to serve (Multicasting)

In order to reduce the bandwidth requirements for content providers, the best solution is using End System Multicasting over Peer-To-Peer (P2P) networks.

End System Multicasting is a solution for one-to-many and many-to-many distribution services. Classical (IP) Multicast is based on minimal functionalities offered by IP level and it lacks of flow and congestion control, session management, and so on. End System Multicasting implements advanced distribution services

In this presentation (Overlay Networks) is described the state of art of IP Multicasting. The main issues involved in this research field are the following:

  • How node informations should be sent from one peer to the others?
  • How organize the peers in the overlay network?
