Media distribution via podcasts is a relatively new phenomenon which follows a different paradigm compared to traditional modes of content delivery. Despite its rapidly increasing subscriber base, podcast distribution has not been measured or modeled adequately, if at all. As our contribution, we develop a measurement based profile of podcasters. This profile consists of a comprehensive and detailed...
Peer-to-Peer (P2P) networks have proven to be an efficient and successful mechanism for file sharing over the Internet. However, current P2P protocols have long worst case query latencies which prevents them from be employed for real time applications. Popularity of objects in these networks can change rapidly and augurs the need for a rapid and lightweight content replication strategy to reduce search...
Peer to peer (P2P) flows constitute a large portion of Internet traffic meandering through different ISP domains. Hence, it is of prime concern for ISPs to try and gauge the number of active P2P users and where they are located, both inside and outside their respective domains. An analysis of where P2P users are located in the Internet provides an insight into understanding which ISPs harbor a majority...
We investigate the shared-wavelength WDM-PON architecture which accommodates bursty downstream traffic. Based on the architecture, the proposed flow-scheduling algorithm can support user-specified service level agreements (SLAs), especially under high traffic load. Illustrative results demonstrate that the new architecture can provide a user with a number of streaming flows with bandwidth and maximum...
