Video streaming is a kind of bandwidth hungry application. As a consequence, the number of streaming flows may be restricted. In this paper, a novel video streaming framework is designed, where multiple NVSs (Network Video Servers) form into a server group to collaboratively provide quality services. A novel problem - Maximum Streaming Flows (MSF), aiming to maximize the number of simultaneously online...
Wireless information-centric networks consider storage one of the network primitives, and propose to cache data within the network in order to improve latency to access content and reduce bandwidth consumption. We study the throughput capacity of an information-centric network when the data cached in each node has a limited lifetime. The results show that with some fixed request and cache expiration...
An information-centric network should realize significant economies by exploiting a favourable memory-bandwidth tradeoff: it is cheaper to store copies of popular content close to users than to fetch them repeatedly over the Internet. We evaluate this tradeoff for some simple cache network structures under realistic assumptions concerning the size of the content catalogue and its popularity distribution...
