CIRCULATED PART DESIGNS CIRCULATED PART DESIGNS • There is no qualification in a circulated part engineering among clients and servers. • Each distributable element is a part that offers services to other parts and receives services from them. • Part communication is facilitated through a middleware system. ADVANTAGES OF DISPERSED PART DESIGN • It permits the framework planner to postpone choices on where and how administrations ought to be given.. • A highly open system architecture permits new resources to be added as required. • The system is flexible and scalable. • It is possible to reconfigure the system dynamically with objects moving across the network as needed. DETRIMENTS OF DISPERSED PART DESIGN • Distributed part models face two major disadvantages: 1. They are more mind boggling to plan than client-server frameworks. 2. Standardized middleware for distributed part systems has never been adopted by the community. Various vendors, such as Microsoft and Sun, have developed unique, incompatible middleware. • As a result, service-oriented models are frequently replacing distributed part architectures. SHARED DESIGNS • Shared (P2P) systems are decentralized systems where computations may be carried out by any node in the network. • The overall system is designed to leverage the computational power and storage of a large number of networked computers. • While most P2P systems have been private, there is increasing commercial use of this technology. 1 DISTRIBUTED SYSTEMS EXAMPLES • File Sharing Systems: Based on the BitTorrent protocol. • Messaging Systems: Examples include Babble. • Payment Systems: Bitcoin. • Databases: Freenet is a decentralized database. • Phone Systems: Viber. • Computation Systems. P2P BUILDING MODELS 1. Logical Network Architecture: o Decentralized structures. o Semi-centralized models. 2. Application Architecture: o Traditional organization of components making up a P2P application. o Focus on network designs. TYPES OF P2P ARCHITECTURE • Decentralized P2P architecture. • Semi-centralized P2P architecture. 2
