Hybrid Peer-to-Peer (P2P) architecture is used to provide directory services for network clusters to share resources distributed among devices within and across clusters. With increased distributed multimedia digital libraries dominating networks like Internet, providing an efficient Quality of Service (QoS) based on the constraints of the content type is crucial. These value added services aid in revenue enhancements for Internet Service Providers (ISPs). In this paper, we propose a dynamic Content Based Query Response (CBQR) algorithm at the Super Peer, to forward the query selectively in real time to a set of appropriate peers, based on the QoS constraints like delay, download rate of the requested content and select the best Content Provider Peer that satisfies these constraints. The peers dynamically update the Super Peer with content type and performance parameters at time slots allocated by Content Updation Periodicity Selection (CUPS) algorithm, to reduce network overhead. We have evaluated the proposed approach by enhancing the Gnutella protocol with QoS services.
