Peer-to-Peer resource discovery in Grids: Models and systems

Recently, there have been considerable efforts towards the convergence between P2P and Grid computing in order to reach a solution that combines 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. Most of the proposed solutions for decentralizing the Grid Information Service (GIS) are based on completely flat overlays. The major contribution for this paper is the investigation and analysis of a novel resource discovery mechanism intended for Grid applications. It introduces a hierarchical structured peerto-peer architecture for the GIS to support resource discovery in Grid environments. Such a structure has the advantage of being scalable while providing faultisolation and security, effective caching and bandwidth utilization, and hierarchical access control. In addition, it will lead to a reliable, guaranteed sublinear search which returns results within a bounded interval of time and with a smaller amount of generated traffic. The proposed framework is fully described. Preliminary analysis and discussion of the approach are also introduced.

Efficient Resource discovery mechanism is one of the fundamental requirement for Grid computing systems, as it aids in resource management and scheduling of applications. Resource discovery activity involve searching for the appropriate resource types that match the user's application requirements. Various kinds of solutions to grid resource discovery have been suggested, including the centralised and hierarchical information server approach. However, both of these approaches have serious limitations in regards to scalability, fault-tolerance and network congestion. To overcome these limitations, indexing resource information using a decentralised (such as Peer-to-Peer (P2P)) network model has been actively proposed in the past few years.

As deployed Grids increase from tens to thousands of nodes, peer-to-peer (P2P) techniques and protocols can be used to implement scalable services and applications. The super-peer model is a novel approach that helps the convergence of P2P models and Grid environments and can be used to deploy a P2P information service in Grids. A super-peer serves a single physical organization in a Grid, and manages metadata associated to the resources provided by the nodes of that organization.

Multitude of resources pooled in grid environments require a scalable, efficient, low-cost and self-organizing resource discovery mechanisms. P2P networks possess overlapping characteristics like large scale resource sharing and dynamic nature of participation. P2P style resource discovery approaches have been employed in the grid environments. We propose a P2P based resource discovery approach with modified features like customized neighbourhood defined according to the user preferences and distributed search using directed flow of requests contrary to the blind propagation of P2P systems.

Abstract. Several features of today's Grids are based on centralized or hierarchical services. However, as Grid sizes increase, some of their functions should be decentralized to avoid bottlenecks and guarantee scalability. A way to provide Grid scalability is to adopt Peer-to-Peer (P2P) models and protocols to implement non hierarchical decentralized Grid services and systems. A core Grid functionality that could be effectively redesigned using the P2P model is resource discovery.

Abstract Several systems adopting Peer-to-Peer (P2P) solutions for resource discovery in Grids have recently been proposed. This report looks at a P2P resource discovery framework aiming to manage various Grid resources and complex queries. Following the discussion on characteristics of Grid resources and related query requirements, a DHT-based framework leveraging different P2P resource discovery techniques is proposed.

Distributed discovery service is a main concept in the scalable and dynamic grid environments. In this paper, based on the super-peer technique, we propose a new topology for the grid discovery service. The model is designed in such a way that each super-peer within the cluster has the routing indices (RIs) based on cobweb and uses the hop-count routing index (HRI) to select the best neighbor. Besides, each super-peer includes a cache table, which stores the query and the query results. Furthermore, from the point of view of the response time and the number of submitted messages, we compare the new model with an existing method. An illustrative simulation is also presented to show the efficiency and validation of the new technique.

As deployed Grids increase from tens to thousands of nodes, Peer-to-Peer (P2P) techniques and protocols can be used to implement scalable services and applications. The super-peer model is a novel approach that helps the convergence of P2P models and Grid environments and can be used to deploy a P2P information service in Grids. A super-peer serves a single Virtual Organization (VO) in a Grid, and manages metadata associated to the resources provided by the nodes of that VO.
