Optimizing the Throughput of Data-Driven Peer-to-Peer Streaming

Meng Zhang, Yongqiang Xiong, Qian Zhang, Lifeng Sun, Shiqiang Yang
2009 IEEE Transactions on Parallel and Distributed Systems  
We then propose both the global optimal scheduling scheme and distributed heuristic algorithm to optimize the system throughput.  ...  However, few of them concentrate on optimizing the streaming data scheduling to maximize the throughput of a constructed overlay.  ...  Section 3 describes our heuristic distributed algorithm. Then, in Section 4, we employ layered video coding and extend our algorithm for multiple streaming rates.  ...

Overlay self-organization for traffic reduction in multi-broker publish-subscribe systems

Elisabetta Di Nitto, Daniel J. Dubois, Raffaela Mirandola
2009 Proceedings of the 6th international conference on Autonomic computing - ICAC '09  
Usually the broker overlay is fixed once for all. In this work we propose a heuristic-based strategy to modify such overlay for optimizing the message flow.  ...  The approach we adopt is inspired by self-organization in biology and makes the broker overlay behave as an autonomic distributed system.  ...  This approach takes some elements from bio-inspired evolutionary computing, such as the need of a minimal amount of randomness to achieve optimal results [19, 14] .  ...
