Distributed Shared Files Management
Most often file sharing is the common and basic requirement of any domain. Users can use a system that connects to all the peers in the network to access the shared files. Files of interest can then be downloaded directly from the users in the network.

43.1 Introduction In a computer system a file is a named object that comes into existence by explicit creation, is immune to temporary failures in the system and persists until explicitly destroyed. The two main purposes of using files are as follows: 1. Permanent storage of information. 2. Sharing of information. Common methods of storage, transmission, and distribution used in file sharing include manual sharing using removable media, centralized server on computer networks, World Wide Web-based hyperlinked documents and the use of distributed peer-to-peer networking. The most common and feasible approach is to S. Malgaonkar (&) S. Surve Thadomal Shahani College of Engineering, Bandra (West), Mumbai 400 050, India e-mail: [email protected] S.

use peer to peer file sharing for implementing a distributed shared files management system. Peer to peer file sharing is economically efficient, when the user wants to find specific information, searching for the same would require a lot of human efforts and time. If the upcoming technologies are clubbed with the existing ones it can help better understand the whole system. Thus extending the idea of peer to peer in the file sharing environment helps better built the whole system. In [1] the key features in P2P file transfer are highlighted. In [2] a reliable and simple P2P file sharing system is described which avoids unnecessary data redundancy and connectivity issues among peers by maintaining an adapter which optimizes the working of the entire file sharing system. The disadvantages of a client server file system which do not scale with respect to the number of users and exhibit a single point failure are further highlighted in [3] and also insists on the utilization of a fault tolerance mechanism.
43.1.1 User Interaction Scenario When a user interacts with the system when joined to a particular network, the user adds the file entry that needs to be shared among the clients in the network. The user mentions the category of the file and also adds its description so the other users are aware about the contents of the file. A user can also search for a particular file entry from the required parameters (name, category or description) as the users in a network can share hundreds of file entries and it is
