Today, the world is on the anvil of being shrunk into a global net. All the systems around the world are to be used in the epoch of a nanosecond even when installed across continents and oceans. This is possible only through networks. It is in this context that networks become crucial to the viability of science and engineering research. The unprecedented growth of networking has helped in breaking all geographic barriers of the world and building the information super highway and global village.
In this direction a new technology has developed in the past few years which makes it possible to interconnect many disparate networks and make them work as a co-coordinated unit. Thus the technology is designed to foster the communication between 2 machines with hardware architectures, to accommodate and use any packet switched network hardware and to accommodate multiple operating systems.
It is in this context that Gateway has gained importance for communications between disparate networks.
3.1 Existing System
The present system is having different networks for each department. Where in the files has to be manually transferred. which is not a good way of practice of file transfer, for that we have given this proposed system. Where the file transfer is done through the networks.
3.2 Problem Statement
A computer network is a communication system for connecting end system, in order to send messages or files. From one to another. So to achieve proper communication the network should be a dedicated one. the interconnection i.e. physical connections should be proper.
Whenever a new network is added it should not disturb the existing network. Similarly when a network is deleted communication should be carried on properly
The network should be reachable with a high reliability and should provide consistent routing and should be able to provide solution for the routing problem.
3.3 Proposed System
In the proposed system all the sub-networks are added to the gateway and the transfer of the different document and file takes place through this gate way. Where we can not only reduce the delay in file transfer but also we can maintain the log.
This project is divided into four modules:
In this module we provide mechanisms for adding a new network to a Gateway and deleting the existing network from the Gateway and displaying a routing table for a Gateway.
In this module there are three methods first, to create a route message, second sending a routing message to other gateways, third updating the routing message.
In this module we develop an application program to know the date and time the routing table is transferred to other gateway.
In this module the errors occurred by the invalid inputs given by the user or any unexpected circumstances is reported to the gateway by using ICMP protocol.
