Tree-assisted gossiping for overlay video distribution

Peer Assisted Content Distribution over Router Assisted Overlay Multicast

While multicasting is considered valuable for content distribution, it is not widely supported on the Internet, despite the emergence of scalable overlay schemes. Content providers have instead turned to peer assisted content distribution in order to efficiently serve large numbers of clients, thus removing the bandwidth bottleneck from their side but placing a heavy burden on the clients. Even...

Simulating Router Assisted Overlay Multicast

Provisioning overlay distribution networks

Future entertainment services are expected to be increasingly interactive, on demand and personalized. This paper aims to address the challenge of provisioning network and server resources to support the distribution of these services over the Internet. We propose the Overlay Distribution Network (ODN) as a cost-effective means to deliver these services. Because ODNs are created over shared net...

Performance of edge-based multicast overlay trees for real time MPEG video distribution

This work proposes an edge-node multicast overlay to create a tree capable of performing point to multipoint distribution of real time video (i.e., videoconference) with a hard upper bound on end-to-end delay. By moving the tree configuration, replication, and network monitoring to the edge routers instead of end systems, the trees can be constructed using the knowledge of overlay link bandwidt...

An Overlay Architecture for Live Video Distribution over Heterogeneous Ip Networks

The main concepts to attain, when delivering live contents to thousands of Internet users over IP networks, are scalability and heterogeneity. Scalability points to the use of IP Multicast routing protocols, however the low dissemination of IP Multicast in current Access Networks also makes unicast an indispensable solution. In terms of Quality of Service (QoS), the Integrated Services (IntServ...
