Abstract:

With the progress of network technology, the Internet has shifted from barely file data exchang to application services. There are plenty of defects in the traditional EndtoEnd network architecture, such as deficiency of resource controllability, incapability of guarantee QoS, etc. So it is unsuitable to transfer the mass streaming media data. Although the P2P applications alleviate the load of servers, they damage the profit of ISP. In this paper, we present an EdgetoEdge network service model for mass streaming media transmission, which isolates the edge network from the core network, adds storage and calculation functions at the edge to increase network performance.We analyse the key techniques in this new network architecture, and network simulation results show it can decrease the stratup latency of users effectively and lessen the traffic flow of the core netwok remarkably.
