Abstract

In this paper, we propose the structure of the logical hierarchical cluster for the distributed multimedia on demand according to block the nodes cache. The structure of the logical hierarchy is lazily maintained by all members in the decentralized manner. The global load balance is achieved as the root of each LHC is mapped into the system randomly. The LHC is expanded dynamically with the two application policies. The local load balance is applied to fine-tune the load of nodes of different LHCs within a local region. The integration of topology with resource management simplifies the server selection largely.
