Push Less and Pull the Current Highest Demanded Data Item to Decrease the Waiting Time in Asymmetric Communication Environments [chapter]

Cristina M. Pinotti, Navrati Saxena
2002 Lecture Notes in Computer Science  
We introduce a hybrid scheduling that effectively combines broadcasting for very popular data (push data) and dissemination upon-request for less popular data (pull data) in asymmetric communication environments  ...  in a pure push system and also on that spent in some of the hybrid systems already proposed in literature.  ...  To overcome such a drawback, we propose a new hybrid scheduling which continuously broadcasts one push item and disseminates one pull item.  ...

2013 Proceedings of the VLDB Endowment  
We also evaluate our algorithms on a real social networking system prototype and we show that the actual increase in throughput corresponds nicely to the gain anticipated by our cost function.  ...  We propose an O(log n) approximation algorithm and a heuristic to solve the problem, and evaluate them using the full Twitter and Flickr social graphs, which have up to billions of edges.  ...  With a push-all schedule, the system pushes new events by Art to Billie's view-the dashed thick red arrow in Figure 2 (b).  ...

Pattern-Push: A low-delay mesh-push scheduling for live peer-to-peer streaming

Guifeng Zheng, S.-H. Gary Chan, Xiaonan Luo, Ali C. Begen
2009 2009 IEEE International Conference on Multimedia and Expo  
Simulation results show that pattern-push achieves a significantly lower delay and overhead as compared with both traditional and recent scheduling algorithms proposed in the literature.  ...  It is challenging to develop a scheduling algorithm that achieves low delay given heterogeneous bandwidth, propagation delays and available content in all the parents.  ...  Content scheduling may be roughly divided into four categories: tree-push, mesh-pull, hybrid pull-push, and mesh-push.  ...

Practical algorithm for minimum delay peer-to-peer media streaming

Jun Luo
2010 2010 IEEE International Conference on Multimedia and Expo  
a systematic way to construct the chunk scheduling that achieves the minimum delay bound.  ...  We design algorithms to construct and maintain our SNowbAll multi-tree Pushing (SNAP) overlay. Our simulations in ns-2 indicate that our approach outperforms other tree-based mechanisms.  ...  Having such a complete neighbor table at every peer, SNAP can proceed in a distributed way: each peer, upon receiving a new chunk, chooses a subset of peers in a round-robin fashion and pushes the chunk  ...
