Essay Example Figure 1 shows the network diagram of such communication; Internet Service Provider (ISP) Server for a certain region will listen to a number of internet users. The client will request for connection and connection request will be catered by the server on a queue mechanism so that there are no clients left without service. Another mechanism to handle requests that is very common among multi client servers is based on priority of messages. The server can listen to n number of clients and clients can disconnect from the server at any point of time. There are generally two approaches to handle multi client server implementation. One approach is to have singleton servers for each client i.e. a server instance is created every time a request is received for a connection. This approach is not very practical for real-time systems. The other approach is to designate one server as the ‘connection manager’ that will be catering to a number of clients by retrieving their individual information on need basis. The TCP/IP model, also termed as Internet Protocol Suite, defines the format and implementation of a set of networking protocols to facilitate communication between nodes in a network. It is the set of protocols that is used for Internet and other networks. This model is based on protocols and it does not distinguish between service and protocols. TCP/IP model is known to have 4 layers and slightly different names have been given to the respective layers by different researchers. The names that have been chosen by Tanenbaum are: Multi client server gives service to n number of client. Communication takes place over TCP/IP and messages are passed on from the layers of the TCP/IP model to the end-host. OSI reference model can be considered as a guidance tool whereas the TCP/IP model can be used for implementation. Cygwin provides the Microsoft Windows users with a Linux-like platform.
