The concept of peer-assisted content delivery networks (CDNs) lets other nearby altruistic clients forward requested content files instead of the source servers, which works to localize overall traffic. Our prior work proposed a traffic engineering scheme to localize traffic in peer-assisted CDNs. To induce altruistic clients to download content files that are most likely to contribute to localizing...
When a link or node failure occurs in a network, flows are detoured and therefore the hop counts of the flows increase. This increase could drastically deteriorate the quality of a network. The flow hop length stability as well as network connectivity is important for network reliability. We investigate a network design method that improves stability and connectivity of a network during a failure...
The transmission bandwidth consumed by delivering rich content, such as movie files, is enormous, so it is urgent for ISPs to design an efficient delivery system minimizing the amount of network resources consumed. To efficiently deliver web content, a content delivery networks (CDNs) have been widely used. CDN providers collocate a huge number of servers within multiple ISPs without being informed...
