 The feasibility of supporting large-scale live streaming applications with dynamic application end-points

 == P2P Overlay Network for content delivery ==
 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)
+* there are scalability issues due to the 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 at application level, so each node being involved in the distribution should forward the stream to several other nodes using a one-to-one protocol (TCP or UDP). P2P topologies should reduce this flow duplication.
