In order to evaluate the influence of neighbors' quality to P2P streaming system's performance during scheduling, this paper establishes a markov chain based differential function model to analyze the relationship between peer's average startup delay and probability neighbors have wanted data as well as neighbors' available upload bandwidth. This paper also proposes a scheduling feedback algorithm,...
Reducing server's bandwidth pressure is one of the key problems in the designing of peer-to-peer video-on-demand system. In this paper, we analysis and model this problem via using the “pseudo sequence scheduling”, which is widely used by many peer-to-peer video-on-demand systems. We reveal the relations between the server bandwidth consumption, the cache size and the join speed of peers. This result...
Data scheduling is the key issue in peer-to-peer streaming system, especially in peer-to-peer VoD system. This paper mainly focuses on data chunkspsila priority definition of data scheduling in peer-to-peer VoD system. After carefully studying the meanings of regular rarest first scheduling and random scheduling, a local-rarest-random-heurist (LR2H) scheduling is proposed in order to fully use the...
In a content distribution network based on overlay networks, the peer's upload bandwidth is always constrained. To optimize the system performance, one problem is how to assign the upload capacity to the right neighbors for transferring data blocks. In a system using network coding technology, a strategy which is to select the right neighbors based upon the degrees of them is proposed. The selection...
Chord is known to be limited in routing efficiency since all nodes are on the overlay without considering the underlying network topology. In this paper, a Chord routing algorithm based on limited network layer multicast, called MChord, is proposed, which uses multicast technology to obtain physical neighbor information for routing. Simulation shows that it can shorten network search delay greatly,...
