A PROJECT REPORT ON NETWORK SIMULATION OF DATA THROUGH ATM SWITCH
ABSTRACT
The project is developed to keep check the route of the data thorough ATM switch. We can check that which source is transmitting the cell at which time and which destination is receiving that cell at which particular time. The switches are created automatically according to the number of source and destinations. We will be able to visualize the path followed by the cell during transmission.
The background of project can be seen as it can be used from low level to high level application with some modifications.
All the results can be checked by just seeing the LOG files of the source, destination and switches.
If the requesting source is of type ABR and CBR then:
Log the information in files.
Send all the cells in the burst to the switch.
If in the process of sending cells to the switch congestion occurs then Log the information and forward the current cell.
At the switches on receiving the cell
Log the information in files.
Determine the next switch/destination and send the cell.
At the destination on receiving the cell
Log the information in files.
Free the cell.
ATM networks
Asynchronous Transfer Mode Technology: Asynchronous Transfer Mode (ATM) is a high performance connection oriented networking architecture which has been designed to carry traffic for communication services, such as voice and video telephony, broadcast video, data file transfer, world wide web applications, etc. ATM is connection-oriented in that an application must first establish connection before starting to communicate. Once a connection is set up, resources are reserved along a path from source to the destination. ATM has been designed to be efficient for time sensitive data such as digitized voice or video. In order to do so, a small fixed length packet of 53 byte long consisting of 5-byte cells header and 48-byte payload (user data) called cell, is transmitted over each ATM connection breaking up long message into consecutive cells. ATM guarantees that cells within a stream are delivered in the same order as they were transmitted. ATM technology offers the benefits of a switched architecture while adding broadband capabilities.
PRESENT SITUATION IN TELECOMMUNICATION WORLD
Today’s telecommunication networks are characterized by specialization. This means that foe every individual telecommunication service At least one network exists to transport this service. Each of the networks is specially designed for a specific service and is often not at all applicable to the transport another service. An important consequence of this service specialization is the existence of a large number of often- worldwide independent networks, each requiring its own design, manufacturing and maintenance.
Project Background
The project is developed to keep check the route of the data thorough ATM switch. We can check that which source is transmitting the cell at which time and which destination is receiving that cell at which particular time. The switches are created automatically according to the number of source and destinations. We will be able to visualize the path followed by the cell during transmission.
The background of project can be seen as it can be used from low level to high level application with some modifications.
All the results can be checked by just seeing the LOG files of the source, destination and switches.
