Research on Application Layer Multicast in Interactive Streaming Media
Daoxu Chen · 2009
Internetware tends to resolve the integrating and sharing of various kinds of resources in open,dynamic and changing Internet environment.In the recent years,streaming media applications becomes more and more popular on the Internet,which introduced challenging issues such as resource sharing and bandwidth saving.Application layer multicast has shown to be efficient in reducing network traffic for large-scale multimedia applications.However,interactive operations such as VCR may cause frequently reconstruction of multicast trees,which will degrade the system performance.We proposed a protocol called ISMT (Interactive Streaming Multicast Tree) to construct and maintain interactive application layer multicast trees,which aims at reducing user response delay and enhancing system scalability.The effectiveness of the ISMT protocol is validated by simulations.
