To simulate a Bus-Star Hybrid Topology using OPNET, in a single network aggregating both bus and star topologies. We normally contain numerous star networks linked to a central bus, to allow effective interaction among while sustaining some level of segmentation in a Bus-Star hybrid topology. This configuration is general within LANs and campus networks in which diverse departments or buildings are associated to a central backbone. Following is a series of steps to simulate a Bus-Star Hybrid Topology in OPNET:
Steps to Simulate Bus Star Hybrid Topology Projects in OPNET
Step 1: Set Up the OPNET Environment
- Open OPNET Modeler: Make a new project in OPNET Modeler.
- Create a New Network: Choose New Network, name it to the project, then select a Wired LAN situation like this optimal matches a Bus-Star hybrid topology.
Step 2: Configure the Star Topology Segments
- Place Star Network Devices:
- Choose switches (or hubs, if needed) like the central devices for each star topology in the object palette.
- Append workstations, servers, and other devices, which will be associated to the switches.
- Arrange Nodes in Star Layouts:
- Locate one switch like the center of each star including workstations and servers placed around it.
- Utilize point-to-point links, associate each workstation and server to their central switch. For each cluster or department, this set up makes individual star topologies.
- Set Link Parameters for Star Networks:
- Set up data rate, delay, and error rate to fit the needs of network for each link. Star links frequently utilize high-speed connections such as 1 Gbps or higher to manage traffic in each cluster.
Step 3: Connect Star Networks to the Central Bus
- Create the Central Bus Link:
- Make a unique central bus, which will function as the backbone, to link each star network utilizing the bus link tool.
- Locate the bus to central switch of each star topology can associate to it.
- Connect Each Switch to the Bus:
- Connect central switch (or hub) of each star network to the central bus. This link permits data moving from one star topology to another through the bus.
- Set Bus Link Parameters:
- Set up the data rate, propagation delay, and error rate of bus link deliberating the bandwidth required for inter-cluster interaction. The central bus normally contains a high data rate such as 10 Gbps or higher to manage the combined traffic from every star networks.
Step 4: Define Applications and Traffic Profiles
- Configure Applications:
- Configure applications, which replicate normal network traffic like web browsing, file transfers, video streaming, and VoIP. Every star network can be allocated diverse applications according to the situation.
- Assign Traffic Profiles to Nodes:
- Allocate traffic patterns to nodes in every star network and over star networks utilizing the Profile Config editor. For instance, configure traffic among workstations within the similar star network and to simulate inter-departmental interaction among workstations in diverse star networks.
Step 5: Configure and Run the Simulation
- Set Simulation Parameters:
- In the Simulation tab, configure the simulation duration, and then set up other metrics like data collection granularity.
- Select Performance Metrics:
- Select related performance parameters like throughput, latency, packet delivery ratio, link utilization, and bus collision rate. These parameters support to estimate both intra-star (within clusters) and inter-star (across the bus) performance.
- Run the Simulation:
- Execute the simulation then monitor how traffic flows in each star network and over the central bus. The Bus-Star hybrid topology would allow effective interaction in clusters including the bus to offer a pathway for inter-cluster traffic.
Step 6: Analyze Results
- Review Collected Data:
- Analyse parameters such as latency, throughput, link utilization, and collision rate at the bus to utilize OPNET’s analysis tools. The bus can turn out to be a bottleneck if inter-cluster traffic is high, thus observing bus utilization is critical in a Bus-Star hybrid topology.
- Optimize Configuration if Necessary:
- If the bus link undergoes high utilization or latency then deliberate to maximize the data rate, appending collision management, or to modify traffic loads in star networks minimizing bus traffic.
