A dynamic framework for integrated management of all types of resources in P2P systems

Abstract

Traditional Peer-to-Peer (P2P) systems were restricted to sharing of files on the Internet. Although some of the more recent P2P distributed systems have tried to support transparent sharing of other types of resources, like computer processing power, but none allow and support sharing of all types of resources available on the Internet. This is mainly because the resource management part of P2P systems are custom designed in support of specific features of only one type of resource, making simultaneous access to all types of resources impractical. Another shortcoming of existing P2P systems is that they follow a client/server model of resource sharing that makes them structurally constrained and dependent on dedicated servers (resource managers). Clients must get permission from a limited number of servers to share or access resources, and resource management mechanisms run on these servers. Because resource management by servers is not dynamically reconfigurable, such P2P systems are not scalable to the ever growing extent of Internet. We present an integrated framework for sharing of all types of resources in P2P systems by using a dynamic structure for managing four basic types of resources, namely process, file, memory, and I/O, in the same way they are routinely managed by operating systems. The proposed framework allows P2P systems to use dynamically reconfigurable resource management mechanisms where each machine in the P2P system can at the same time serve both as a server and as a client. The pattern of requests for shared resources at a given time identifies which machines are currently servers and which ones are currently clients. The client server pattern changes with changes in the pattern of requests for distributed resources. Scalable P2P systems with dynamically M. Sharifi ( ) · 150 M.

4-dimensional Model for Describing Status of Peers in Peer-to-Peer Distributed Systems

“…The selected peer-to-peer system should be able to execute with an acceptable accuracy in both the server-oriented and serverless peer-to-peer architecture [29]. This property allows us to evaluate the model in different architectures and compare the obtained Latin square.…”

“…The distributed peer-to-peer system [29] has no primary structure and the execution task definition (basic execution task, known as the basic activity of the system) is always considered a higher priority compared to the system's structure definition. Actually, the system's structure assumes its shape relying on the work performed (request made).…”

A Dynamic Popularity-Aware Load Balancing Algorithm for Structured P2P Systems

“…Another disadvantage about virtual servers is that using them causes a great increase in routing table entries. Considering the above problems about virtual servers, our algorithm does not use of virtual servers [5].…”

A platform independent distributed IPC mechanism in support of programming heterogeneous distributed systems

“…We have successfully used the proposed wrapper approach in distributed discovery of resources in the integrated peer to peer distributed system framework whose principal features have been presented in [5]. Using this mechanism, all four main types of resources (processes, input/output, memory, and file) are discovered using Unix System V interprocess communication mechanisms even when resources are owned by MSWindows peers.…”
