Abstract: | Due to their large bandwidth demand and synchronization requirements, multimedia applications, in general, consume buffers
of huge size, which prevents potential customers from using multimedia services. We recognize the problem and propose a hierarchical
architecture to reduce the buffer size. The architecture can be applied to both 1- and - applications. We establish the architecture by first determining neighbor sets and then applying a grouping algorithm and
a renegotiation process. This architecture can also meet the synchronization requirements of multimedia applications. We evaluate
the performance of the architecture through simulations and compare it with that of a direct connection architecture. The result shows that the hierarchical architecture reduces the buffer size significantly without
serious penalty to the total bandwidth and without introducing extra hot spots. |
