Distributed Networks - Essay Examplee, the different confederates provide the operate and use the provided services 1. Another difference between catch to peer meshworks is based on file storage and access Client- innkeeper networks depend on a central use server for file storage the clients then access the files from the server whereas in peer to peer networks file storage is in the different peers on the network. The surety of the files in peer to peer networks is dependent on the end users while that of client-server networks is dependent on the server administrator. The server on a client server network provides secured access to the client thus providing better levels of security. Implementation of peer to peer network is much cheaper as compared to client-server because no centralized server is call for 3. Peer to peer networks have various benefits over other network architectures, they include Peer to peer networks are cheaper to install as compared to other network arc hitecture because no dedicated server is required for the network. Peer to peer is allows sharing of resources such as printers therefore saving on costs 4. evocation and maintenance of peer to peer networks is easier because no network configurations are required. The peers on the network use individual operating systems. Peer to peer networks are more reliable because the devices on the network are independent i.e. they do not depend on a central server therefore failure of on peer does not affect the exertion of the other peers 1. Peer to peer networks save on time and resources because there is no need for a good time system administrator to write out a server 4. The use of peer to peer networks has its own drawbacks, the disadvantages of this networks include The security levels in peer to peer networks are limited thus there is likely to be transmission of viruses spywares and malware across the network 2. In case of data loss it may be very difficult to recover because e ach peer on the network has its own backup system. Due to lack of centralized administration, its difficult to manage all the activities on the network. Peer to peer networks are good for small networks where high level of security is not required 3. Some of the peer to peer tools currently available in the market include Oversim- Its an open source high performance pretension framework for peer to peer networks. It has an synergetic user interface that visualizes network topologies messages and routing tables. Oversim simulation framework is flexible in its operations because it simulates both structured and unstructured overlay networks. Due to its high performance capability, Oversim can be used to simulate large networks of up to 10000 nodes and also has a network scheme that allows configuration of network topology with practical bandwidths and packet relays which enhances its high performance 2. Peerism is a java developed open source framework that was created to support l arge network scalability. Peerism is composed of two simulation engines
