To simulate an extended bus topology project using OPNET that needs a structured method to configuring the network model, to set up the devices, and to monitor the data flow and interaction in the topology. Given below is a sequential procedure to simulate the Extended Bus Topology in OPNET:
Steps to Simulate Extended Bus Topology Projects in OPNET
Step 1: Set Up the OPNET Environment
- Open OPNET Modeler: Initially, we make a new project in OPNET Modeler.
- Create a New Network: Start a new network model by choosing the New Network option then name it to the project.
Step 2: Configure the Network Topology
- Select Devices: Choose the essential network devices for an extended bus topology in the object palette. Normally, it encompasses workstations, switches if required for extended topology, and bus links.
- Place Devices: Locate the devices on the workspace within the setup, which look like an extended bus topology (workstations linked to a primary cable or bus line).
- Add Bus Links: Link each device to the primary bus to utilize the bus link tool. If more network segments are required then utilize repeaters or additional bus links to prolong the network for an extended bus.
Step 3: Configure Node and Link Parameters
- Set Link Parameters: Choose the bus links then configure link parameters like data rate, propagation delay, and protocol type. For example, Ethernet if we are replicating a general Ethernet bus.
- Set Node Parameters: Set up each node (workstation or server) including related metrics like IP addresses, traffic generation settings, and application types if we intend to replicate certain applications such as web traffic or file transfers.
Step 4: Define Simulation Applications and Traffic
- Application Configuration: Describe the kinds of applications and traffic patterns we need to replicate on the network in the Application Config and Profile Config editors. For instance, configure web browsing, file transfer, or email applications.
- Assign Traffic Profiles: Allocate traffic profiles to certain nodes replicating data flow and utilization over the bus network.
Step 5: Configure and Run the Simulation
- Simulation Configuration: Set parameters such as simulation duration, statistics to collect, and simulation speed in the Simulation tab. Select related statistics like throughput, delay, collision rates, and utilization estimate the network performance.
- Run the Simulation: Start the simulation and we execute it while waiting for accomplishment. We can monitor live statistics within the simulation window or until post-simulation analysis.
Step 6: Analyze Results
- Review Graphs and Data: After the simulation is accomplished, envision data and performance parameters utilizing OPNET’s analysis tools. General parameters such as packet delay, collision rate, and utilization for bus topology.
- Optimize if Needed: We need to adjust link parameters or traffic profiles and re-execute the simulation monitoring diverse performance results depends on analysis.
Tips for an Effective Simulation
- Adjust Link Length and Delay: To deliberate appending realistic propagation delays to links because an extended bus topology crosses a larger area.
- Observe Collision Metrics: Bus topologies are disposed to collisions, thus to examine the collision rates is necessary.
- Experiment with Different Traffic Loads: Diverse traffic loads at the network monitoring how it executes in distinct conditions.
