To address the challenges raised by the Internet usage evolution over the last years, the Content-Centric Networking (CCN) has been proposed. One key feature provided by CCN to improve the efficiency of content delivery is the in-network caching, which has major impact on the system performance. In order to improve caching effectiveness in such systems, studying the functioning of CCN in-network storage...
The growth of real-time content streaming over the Internet has resulted in the use of peer-to-peer (P2P) approaches for scalable content delivery. In such P2P streaming systems, each peer maintains a playout buffer of content chunks which it attempts to fill by contacting other peers in the network. The objective is to ensure that the chunk to be played out is available with high probability while...
With widely application of Peer-to-Peer (P2P) file sharing technique, the P2P traffic occupies most of the current Internet bandwidth. Modeling the behaviors of P2P file sharing systems is important for designing and evaluating such systems. In this paper, we develop a novel model to character the dynamic behaviors of P2P sharing systems. States in microcosmic view are defined and used to describe...

Several proposals on P2P-ISP cooperation have recently been developed using information sharing for locality-based peering. Their benefits in terms of P2P efficiency, ISP cost, and traffic localization have been demonstrated in the single ISP case. However, potential risks associated with such cooperation have not been well examined. This paper develops a taxonomy and a mathematical model to explore...
Abstract-Peer-to-peer (P2P) technology for TV broadcasting over the Internet is becoming more and more popular in the very last years. This paper introduces a network-wide metric to assess the efficiency of P2P streaming systems and develops a mathematical model to explain: (i) the scalability of such architectures with the number of peers, as evidenced by recent measurements; (ii) the initial decrement...
BitTorrent nowadays is one of the most popular peer-to-peer (P2P) applications on the Internet; on the other hand, network address translation (NAT) has become pervasive in almost all networking scenarios. Despite the effort of NAT traversal, it is still very likely that P2P applications cannot receive incoming connection requests properly if they are behind NAT. Although this phenomenon has been...
Peer-to-peer (P2P) live video streaming systems have recently received significant attention, with commercial deployment gaining increased popularity in the Internet. It is evident from our experiences with real-world systems that, it is not uncommon to have hundreds of thousands of users trying to join a program in the first few minutes of a live broadcast. This phenomenon, unique in live streaming...
In this work we analyze propagation of files in the BitTorrent network. The paper covers security problems in peer-to-peer networks and establishes a Malware propagation model. We give overview of existing models and their weaknesses and introduce a propagation or epidemiological model based on model based on real data and real user behavior in the peer-to-peer network BitTorrent. We describe our...
Recent few years, many p2p VoD softwares are widely applied through out the Internet, which gives us an opportunity to study user watching behavior of p2p VoD system at large scale. Many previous works on this area directly regard peer's information transmitting log such as buffer message as peer's watching behavior log. However, the effect of prefetch strategy is not considered. In this paper, we...
