Abstract Peer-to-peer (P2P) based networks have several desirable features for content
distribution, such as low costs, scalability, and fault tolerance. However, they usually fail to …

Most P2P systems divide a file into many pieces and fetch different pieces from many peers
simultaneously. If one of the last few pieces is requested from an extremely slow peer, the …

Despite the recent research efforts on peer-to-peer networks modeling and performance
evaluation, very few literature results have appeared on what concerns the effect of network …

We propose a new efficient singlecast/multicast method for active optical access network
using PLZT 10 nsec high-speed optical switches. The Active Optical Network, called ActiON …

Peer-to-Peer (P2P) networks are distributed systems where no central authority rules the
behavior of the individual peers. These systems relay on the voluntary participation of the …

The increasing success of Video on Demand services poses several challenges to both
network operators and service providers. Due to their heavy bandwidth requirement and the …

P2P applications have become enormously popular and currently take into account a large
majority of the traffic transmitted over the Internet. A unique characteristic of P2P networks is …

Traditional content distribution networks (CDNs), such as Akamai, replicate content at
thousands of servers worldwide in an attempt to bring it closer to end users. Recent years …

With diversification of content distribution systems, multi-view video distribution services,
particularly in real-time services, will become popular in the future. To distribute many …

P2P file sharing is known to be superior to the client-server model especially in terms of
scalability. However, at the beginning of a file distribution process, a lot of requests are still …
