Towards Peer-to-Peer Access Grid
نویسندگان
چکیده
The paper is concerned with supporting natural patterns of scientific collaboration in Access Grid environments. We reveal that no current approach to Access Grid allows dynamic session invocation within on-going Access Grid sessions nor workflow driven session triggering among users involved in that workflow. A model for a lightweight signaling architecture integrated within Access Grid is proposed that allows transparent demand-driven session management. The architecture is configurable both in terms of dynamically changing user preferences and resource requirements. The core of the architecture is the advanced SIP stack embedded both within Access Grid nodes and heterogenous end nodes. This is important in order to allow maximum flexibility of audio,video and workflow presentation to the end users.

A framework for scalable autonomous P2P resource discovery for the grid implementation
Recently, there have been considerable efforts towards the convergence between P2P and Grid computing in order to reach a solution that takes the best of both worlds by exploiting the advantages that each offers. Augmenting the peer-to-peer model to the services of the Grid promises to eliminate bottlenecks and ensure greater scalability, availability, and fault-tolerance. The Grid Information ...
متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
متن کاملTowards Topology-and-Trust-Aware P2P Grid
Grid and P2P are both popular distributed network models nowadays. The grid is a platform to compactly coordinate the distributed resources, while the P2P model assigns an equal position to each peer and allows all the peers to move freely. Because of their different architectures, these two models have their own advantages and limitations, and therefore are used in different applications. In t...

متن کاملTowards an open and scalable data grid solution for environment
The volume and complexity of the data produced in the field of environmental sciences has dramatically increased in the past few years. Traditional data management infrastructures cannot deal with this complexity. Enabling discovery, access and management of this data in a federated manner is the role of the new generation of data grids. We have designed OpEnDaG (Open Environmental Data Grid), ...
