A simple ATM Model in Comnet III


Comnet III is a small commercial application which allows the user to perfume and know about the characteristics of the computer networks. It is a graphic based interface to build a working computer network.  The application was written in MODSIM III programming language.
Thus the figure above is a network model which is done by using the comnet III. It is a TCP/IP ATM mode. A TCP/IP ATM mode is the kind of network in which the data are transported from one point to another point which uses different protocols and networking devices for better, reliable and faster transfer of the data. In the comnet III program given, there are two LAN which is connected by using different network devices such as routers, etc. The ATM mode is invented for the better transfer of the data and overcome the problems of old traditional mode.
In the given model, there are two voice message which help to generate for the model and two session source called file transfer. There are several nodes which are connected in a particular LAN and are connected with different network devices. The two routes which connect the LAN from the transits network called ATM. There are also several circuit link which are connected with each nodes and the networking devices which provide better transfer of the data. The model uses different protocols for the transfer of the data. The model provides two service classes called ABR and CBR which are made for the file transfer and the voice mail. As the voice mail uses ABR protocols and the file transfer uses CBR protocols.  At either side of the transit network are LAN created in the ATM network. the properties of each nodes and the devices can be seen by double clicking on the icon or right clicking and selecting the properties options.

See some sample below to understand the project:

the figure shows two LAN which are connected to the the ATM (transits network  ), as one of the LAN consist of the TR WS and TR server  which are connected to the ATM R1 network devices and the second LAN consist of E Server and E WS nodes and are connected with the ATM R2 network device.
