Early Stage Denial of Service Attacks in BitTorrent: An Experimental Study

The algorithms of BitTorrent used to elect remote peers with whom a peer collaborates and also which pieces of the content it offers, have proved to be highly efficient. This means that a high level of

Distribution of video and of live contents also experienced the P2P mechanisms with success. PPLive, UUSee and others have many of customers, hundreds of channels and thousands of concurrent users. However, major content providers are reluctant to use this technology because no solution to ensure the distribution of only legal contents is provided. In the same way, network operators do not really push towards P2P content distribution because bad organization of the overlay can lead to overload the network and consume a lot of networks resources. In this paper, a secure and legal network-aware P2P video system is introduced, which aims at overcoming those two drawbacks. The design of the system and the evaluation of a prototype showed good results and let us be optimistic about a possible deployment of P2P systems for video delivery, having the support of content providers as well as network operators.
Unit Selection for Speech Synthesis Based on Acoustic Criteria

In a training stage, an acoustic clustering is carried out using context dependent HMMs. In the synthesis stage, an acoustic target is generated and divided into segments corresponding to the required unit sequence. Then, the acoustic unit

Client/Server communication mode from the one hand, and of
the P2P mode from the other hand, hybrid network architectures
have recently gained large popularity. In this paper we propose a
new hybrid architecture that is called P2PWeb, between the
centralized client/server and the non-centralized P2P
architectures for content delivery over the Internet. The main
objective of this proposal is to reduce the load over the server in
order to provide a better Quality of Service (QoS) for the end-users.
A BitTorrent-like protocol has been implemented and
deployed to reach the objective. Moreover, we support our
system with a user-satisfaction control technique that helps to
improve the provided service of the hybrid P2PWeb architecture.
The experimentation results and the performance evaluations
that we have made show the efficiency of the proposed system in
terms of QoS evaluations.
