To simulate a Star-Bus Hybrid Topology using OPNET, we will need to aggregate features of both star and bus topologies. This hybrid configuration normally contains numerous star networks linked through a central bus, to combine the both sets up advantage. Following is a series of steps for setting up and simulating a Star-Bus Hybrid Topology project in OPNET:
Steps to Simulate Star-Bus Hybrid Topology Projects in OPNET
Step 1: Set Up the OPNET Environment
- Open OPNET Modeler: Create a new project in OPNET Modeler.
- Create a New Network: Choose New Network and name it to the project. Select Wired scenario as per the network type, since it will contain modules such as workstations, switches, and bus links.
Step 2: Configure the Star-Bus Hybrid Topology
- Build Star Topologies:
- Choose network devices like workstations, switches, or routers utilizing the object palette.
- Make several star topologies by associating each group of workstations to a central switch or router, to make own star networks.
- Link the workstations to the central switch to utilize point-to-point links for each star set up.
- Connect Star Topologies with a Bus:
- Select the Bus link tool making a central bus from the object palette.
- Link each star network’s central switch or router to the bus link, to connect the star topologies efficiently into a hybrid configuration.
- If we need to replicate the long-distance connections then utilizing repeaters at the bus link we deliberate to enhance the signal strength over extended distances.
Step 3: Configure Network and Link Parameters
- Set Link Parameters:
- Set up link parameters like data rate, delay, and error rate replicating real network conditions for star connections (links among workstations and switches).
- Configure properties such as data rate, propagation delay, and protocol type (e.g., Ethernet) designing a exactly shared interaction medium for the bus link.
- Define Device Attributes:
- In the network, set up attributes of the switches, routers, and workstations deliberating its roles. For instance, allow routing protocols at routers if they want to handle the traffic over the hybrid topology.
Step 4: Define Applications and Traffic Profiles
- Configure Applications:
- Describe applications, which will make traffic at the network like web browsing, file transfers, video streaming, or VoIP in the Application Config and Profile Config editors.
- Assign Traffic Profiles to Nodes:
- Allocate traffic profiles to nodes replicating data transfer in and among the star networks. For example, we can set up traffic among workstations in the similar star and over diverse stars through the bus.
Step 5: Configure and Run the Simulation
- Simulation Configuration:
- In the Simulation tab, we configure the simulation duration, and then set up any other parameters essential for the project such as mobility settings if we need nodes actively modifying the locations or connectivity.
- Select Performance Metrics:
- Select performance metrics, which were related to a hybrid topology like throughput, delay, packet loss, link utilization, collision rate, and network response time.
- Run the Simulation:
- Execute the simulation then monitor how data flows among nodes in each star network and over the bus link linking the stars. This configuration will permit to monitor the communication in own star networks and over the shared bus medium.
Step 6: Analyze Results
- Review Performance Metrics:
- Analyze performance parameters such as delay, throughput, utilization, packet loss, and collisions to utilize OPNET’s analysis tools. Hybrid topologies can occasionally undergo bottlenecks at the bus link, thus observing the utilization is significant.
- Optimize Configuration if Needed:
- We choose to modify parameters such as bus link bandwidth, star link data rates, or traffic distribution attaining the balanced performance over the network depends on the simulation outcomes.
