This paper considers the characteristics of consecutive block loss for streaming services in which a block for a streaming service consists of original data packets and redundant ones generated by forward error correction (FEC). We consider a single-server queueing system with two input processes: a general renewal input process and a Poisson one. The former represents a streaming-packet flow, while...
Recently, Skype has been receiving considerable attention as a peer-to-peer (P2P) Internet telephony application. In Skype, a voice connection is established via super nodes chosen from among ordinary end-user nodes. User information such as an IP address and port number of an online Skype node is managed by super nodes in a decentralized manner where the number of super nodes changes dynamically...
In this paper, the performance of peer-to-peer (P2P) file sharing service based-on flooding search algorithm is analyzed. We focus on six types of four-terminal four-router physical network, and investigate the impact of topology inconsistency and flooding search on the file retrieval performance. The analysis model is based on a two-layer queueing network in which both logical and physical topologies...
