In the current, the structured P2P-based time-shifted streaming system exist the problems that the copy of time-shifted streaming cannot be fully found and the maintenance costs are higher. For resolving the problems a structured P2P-based hierarchy search model for time-shifted streaming, namely Hier-DHT, is proposed. In Hier-DHT, the hierarchy is divided according to the first video block in the...
Peer-to-Peer (P2P) applications running over a distributed hash table (DHT) based overlay do not benefit from dominant characteristics of nodes in the network (such as resources and speed). This paper presents a model for applications to set the predominant features of a node and also a way through which it can prioritize those features on several hierarchical layers. Our architecture is based on...
In this paper, we present an algorithm for an effective flooding procedure with reduced cost in a DHT based P2P network. We describe techniques of flooding and replication that exploit structural constraints to achieve low overhead and higher reliability. These techniques can help to support complex queries in mobile distributed environments with better performance.
Peer-to-Peer Session Initiation Protocol (P2PSIP) is a new technology being standardized in the Internet engineering task force. A P2PSIP network consists of a collection of nodes organized in a peer-to-peer fashion for the purpose of enabling real-time communication using the Session Initiation Protocol (SIP). In this paper, we present experimental results obtained by running a P2PSIP prototype in...
With highly dynamic, structured P2P system needs very large maintenance cost. But there is little research on this kind of maintenance. This article focuses on reducing maintenance cost of structured P2P system and proposes a clone node protocol, CNP for short. We realize a new system based on vxusing CNP, i.e. CNChord. CNP can reduce maintenance cost greatly, and improve query efficiency at some...
A novel load balance technique based on rumor mongering in structured P2P networks is presented in this paper to address the hotspot problem when using DHT P2P networks as the distributed index systems. The basic idea is making use of the periodical topology maintenance communications to piggyback and spread popular information by way of rumor mongering in background. It is shown in the paper that,...
