The application based on P2P technology is one of the most important application of the Internet, but it is often affected by the node failure or abnormal nodes exit. In P2P network, node failure can cause data loss and invalid index, then reduce QoS (Quality of Service) of P2P network, lead to reputation system crashes and so on. Therefore the P2P node failure handling and recovery method can effectively...
This paper describes an Implementation Guide for an emerging standard for autonomic management &control of networks and services, namely the ETSI AFI GANA Reference Model for Autonomic Networking, Cognitive Networking and Self-Management (an emerging standard from ETSI). The implementation guide also takes into consideration the impact of emerging paradigms such as SDN and Virtualization. This...
Peer-to-Peer networks are widely used in media transmission because of its excellent network scalability. Scalable media service is proposed to adapt to different terminal processing abilities. For stratified characteristics of progressive meshes, scalable video, this paper propose a kind of P2P progressive transmission based on multiple implied tree cover. It makes use of several implied tree cover...
The current work deals with the problem of resource management in P2P networks. The topological properties of the overlay network are critical factors that dominate the performance of P2P networks. The inverse Kautz digraph is a good topology to construct the overlay network. We discuss an efficient DHT-based overlay network (MREIK) with Byzantine fault tolerance. MREIK based on many rings which embeds...
Efficient resource search in large-scale unstructured peer-to-peer (P2P) systems remains a fundamental challenge. In order to improve search performance, interest-based search is a good way to tackle the challenge. However, the existing interest-based search algorithms pay attention to user interest model and search history, but ignore some influence factors of improving performance. In this paper,...
Each peer has to obtain information on objects distributed in networks by itself through communicating with its acquaintance peers. An acquaintance might hold obsolete, even incorrect information on objects due to the propagation delay of changed information on the object and faults of peers. It is critical to discuss how a peer can trust acquaintances. We discuss subjective and objective types of...
The following topics are dealt with: cloud computing; resource management; P2P networks; distributed storage; delay assurance; data security; wireless networks; QoS routing; TCP; and service management.
In a peer-to-peer (P2P) overlay network, a peer process (peer) communicates with other peers and manipulates objects in local and remote peers. In a fully distributed, unstructured P2P network, there is no centralized coordinator like index and super peer. Each peer has to communicate with its acquaintance peers and obtain service information of other peers. It is critical for a peer to identify which...
Peer-to-peer applications require high cooperation among users. User cooperation consists of two aspects, upload and download operations. However, not all users are willing to cooperate, and free-riders with little upload bandwidth are widely seen in the applications. Hereby, we put forward the relation between data block probability and the node distance in static situations. Then we discuss the...
