Expediting P2P Video Delivery through a Hybrid Push-Pull Protocol

Push-Pull Incentive-based P2P Live Media Streaming System

Peer-to-peer (P2P) file sharing has become increasingly popular, accounting for as much as 70% of Internet traffic by some estimates. Recently, we have been witnessing the emergence of a new class of popular P2P applications, namely, P2P audio and video streaming. While traditional P2P file distribution applications target elastic data transfers, P2P streaming focuses on the efficient delivery ...

Performance Guarantee in a New Hybrid Push-Pull Scheduling Algorithm

The rapid growth of web services has already given birth to a set of data dissemination applications. Efficient scheduling techniques are necessary to endow such applications with advanced data processing capability. In this paper we have effectively combined broadcasting of very popular (push) data and dissemination of less popular (pull) data to develop a new hybrid scheduling scheme. The sep...

A push-pull queueing system

We consider a two node multiclass queueing network given by two machines each with two classes. There are two streams of jobs: One stream originates in machine 1, which feeds it for further processing to machine 2, and the other stream moves in the opposite direction. We describe a policy for this system which is stable and which keeps both machines busy at all times. We obtain explicit express...

Liveshift: Mesh-pull P2p Live and Time-shifted Video Streaming

Hybrid Push-Pull Query Processing for Sensor Networks

A powerful database abstraction for sensor networks has recently emerged in which clients program the sensors using a declarative query language. Existing work assumes that data is either pushed from sensor nodes to a gateway, or data is pulled from the gateway through queries. We show that hybrid push-pull data dissemination outperforms the pure approaches and offers significant energy savings.
