P2P shared-caching model: using P2P to improve client-server application performance

Abstract

Client-server application model has several drawbacks such as server bottleneck and weak scalability. Peer-to-Peer (P2P) model resolves these problems by distributing tasks on the nodes participating in the system. P2P application development and protocol designing are much more difficult than client-server model. This paper proposes an approach to take the advantages of both models: the scalability of the P2P model and the simplicity of the client-server model. This paper presents a hybrid P2P and client-server model to achieve both goals based on caching mechanism which allows using cache content not only on a single client, but for all clients in the system. The proposed model has been applied to implement a Web application.
