Accurate, real time identification of P2P traffic is especially important for network management, because they seriously affect QoS of normal network services. In this paper, we propose an omnibus approach to identify Bit Torrent (BT) traffic in real time. We apply application signatures to identify unencrypted traffic. And for those encrypted BT traffic, we propose a message stream model according...
Currently, P2P application accounts for a majority of the network traffic. It is significant to study P2P recognition for network monitoring and management, as well as the improvement of service quality. There are many ways to identify P2P traffic, but it is difficult to identify effectively with only one method. To obtain the optimal classification, different methods should be used comprehensively...
Flooding search is a basic searching scheme for unstructured peer-to-peer networks. This technique produces exponentially redundant messages in each hop. Subsequent growths of redundant messages will limit system scalability and will cause unnecessary traffic in network areas. To improve this searching scheme and reduce redundant messages, this paper proposed a novel algorithm (SmoothFlood) which...
IP Television (IPTV) is a new service that is growing up very quick in recent years. Its implementation is performed as a Triple-Play service, being the integration of voice, high-speed data and television. Moreover, the network traffic has been increased due to the use of VoIP, video or P2P. It is also creating congestion problems to the network provider and has high impact on the quality of IPTV...
Peer-to-Peer (P2P) systems gained popularity and are responsible for a large share of today's Internet traffic. Nevertheless, their dynamic nature and the intended lack of control through central instances make their behavior unpredictable and, therefore, it is difficult to achieve a high level of Quality-of-Service for P2P traffic. Thus, peers are themselves responsible for dealing with these issues...
Convenient, rapid, efficient and anonymous characteristic of P2P technology, enables P2P network gathering enormous users very quickly, and P2P traffic has occupied 60~80% bandwidth of Internet. Such giant traffic has formed a threat to the service quality of other Internet application and the security of Internet itself. However, most study about P2P traffic focuses on traffic monitoring and characteristic...
Peer-to-peer (P2P) networks have introduced a distributed communication paradigm, which is useful for many communication services and still accounts for a considerable fraction of the Internet traffic. We discuss the efficiency of P2P content distribution as compared to alternative content delivery overlays.
The following topics were dealt with: local computer networks; peer-to-peer; QoS; wireless sensor networks; radio networks; storage; distribution; traffic characterisation; network routing; optical networks; services; traffic control; power efficiency; wireless local area networks; network security; ad hoc networks; multicast networks; network management; DiffServ; mobile networks; resource allocation;...
