Peer-to-Peer Distribution of Services

2005

Several aspects of today's Grids are based on centralized or hierarchical services. However, as Grids increase their size from tens to thousands of hosts, functionalities should be decentralized to avoid bottlenecks and guarantee scalability. A way to ensure Grid scalability is to adopt Peer-to-Peer (P2P) models and techniques to implement non-hierarchical decentralized Grid services and systems.

Making Grids Work, 2008

In this paper, we discuss how Peer-to-Peer data distribution techniques can be adapted to Desktop Grid computing environments, particularly to the BOINC platform. To date, Desktop Grid systems have focused primarily on utilizing spare CPU cycles, yet have neglected to take advantage of client network capabilities. Leveraging client bandwidth will not only benefit current projects by lowering their overheads but will also facilitate Destkop Grid adoption by data-heavy applications. In this paper, weoutline two approaches to Peer-to-Peer data sharing that could be adapted for volunteer computing platforms: the highly successful BitTorrent protocol; and, a more complex, yet secure and customizable, hierarchal Peer-to-Peer data center approach.

A Grid information system should rely upon two basic features: the replication and dissemination of information about Grid services and resources, and an intelligent distribution of such information among Grid hosts. This paper examines an approach based on ant-based systems to replicate and map Grid services information on Grid hosts according to a given semantic classification of such services. Information is disseminated by agents (ants), which traverse the Grid by exploiting the P2P interconnections among Grid hosts. An entropy index is used to evaluate the performance of the proposed Ant-based Replication and MApping protocol (ARMAP), and control the dissemination of resource information. This approach enables the use of a semi-informed search algorithm which can drive query messages towards a cluster of peers having information about resources belonging to the requested class. A simulation analysis has been performed to evaluate the performance of the ARMAP protocol.

process. Peer-to-peer networks also present that same challenge; even augmented due to the larger set of potential service nodes and new services that can be created. A framework for service deployment will facilitate service introduction in both cases.

Active networks have been researched for years and many studies have been done in the active node architecture, the active networks protocols and the needed functionalities. However, some of these functionalities do not achieve satisfactory results. The deployment of services in active nodes still remains a challenge, and consequently inhibits the widespread use of such networks. In this paper, a new concept based on a Peer-to-Peer system to enhance the service deployment in active networks is presented. This P2P system is used by active nodes to advertise theirs capabilities, which enables "control active nodes" to perform the service deployment, depending on the service requirements and constraints. The concept of administrative domains is also taken into account for widespread active networks. The originality of this work lies on the complete integration of the active networks and P2P systems with the goal of rendering service operators the capacity to deploy new services according to each request and the availability of the resources.

A Peer-to-Peer (P2P) Grid would comprise services that include those of Grids and P2P networks and naturally support environments that have features of both limiting cases. Such a P2P grid integrates the evolving ideas of computational grids, distributed objects, web services, P2P networks and message oriented middleware. In this paper we investigate the architecture, comprising a distributed brokering system that will support such a hybrid environment. Access to services can then be mediated either by the middleware or alternatively by direct P2P interactions between machines.

Resource discovery is a key issue in Grid environments, since applications are usually constructed by composing hardware and software resources that need to be found and selected. Classical approaches to Grid resource discovery, based on centralized or hierarchical approaches, do not guarantee scalability in large-scale, dynamic Grid environments. On the other hand, the Peer-to-Peer (P2P) paradigm is emerging as a convenient model to achieve scalability in distributed systems and applications.
