Efficient Distributed Search for Multicast Session Keywords

mDNS is a proposed DNS-aware, hierarchical, and scalable multicast session directory architecture that enables multicast session registration and makes them discoverable in real time. It supports domain-specific as well as global searches for candidate sessions. This paper improves mDNS global search algorithm and addresses various security and scalability concerns that remained in mDNS. We propose distributing the overall keyword space among designated MSD servers using hash values. In contrast to other P2P keyword search approaches, we propose IP style prefix routing on the keyword hashes to locate the appropriate MSD server in order to register or retrieve any globally-scoped multicast session. This supports efficient and fast distributed keyword search.
