Abstract EN
Multi-channel Peer-to-Peer (P2P) Video-on-Demand (VoD) systems can be categorized into independent-channel P2P VoD systems and correlated-channel P2P VoD systems.
Streaming capacity for a channel is defined as the maximal streaming rate that can be received by every user of the channel.
In this paper, we study the streaming capacity problem in multi-channel P2P VoD systems.
In an independent-channel P2P VoD system, there is no resource correlation among channels.
Therefore, we can find the average streaming capacity for the independent-channel P2P VoD system by finding the streaming capacity for each individual channel, respectively.
We propose a distributed algorithm to solve the streaming capacity problem for a single channel in an independent-channel P2P VoD system.
The average streaming capacity for a correlated-channel P2P VoD system depends on both the intra-channel and cross-channel resource allocation.
To better utilize the cross-channel resources, we first optimize the server upload allocation among channels to maximize the average streaming capacity and then propose cross-channel helpers to enable cross-channel sharing of peer upload bandwidths.
We demonstrate in the simulations that the correlated-channel P2P VoD systems with both intra-channel and cross-channel resource allocation can obtain a higher average streaming capacity compared to the independent-channel P2P VoD systems with only intra-channel resource allocation.
