Steps to Simulate Dijkstra’s Link-State Routing Projects in OPNET

1. Set Up the OPNET Project:
   • Launch OPNET Modeler and initiate a new project by denoting a single project and situation name.
   • For the simulation, select a proper network scale like a small enterprise or campus network, since Link-State Routing is well-matched for medium to large networks.
2. Build the Network Topology:
   • Locate the nodes, which will perform like routers, switches, and end-hosts in the network design workspace. OPNET offers a device’s libraries that contain routers along with configurable routing protocols.
   • Organize these devices making a network topology, for shortest path calculation in which every node will utilize the Dijkstra’s algorithm.
3. Configure Routing Protocols:
   • Choose every single router node for launch the node’s attributes, and traverse to the IP routing settings.
   • Configure every router utilizing OSPF (Open Shortest Path First), since OSPF is depends on the Dijkstra’s Link-State Algorithm, for Link-State Routing.
   • OSPF settings can be discovered within the routing protocols in the IP layer set up. In OPNET, this protocol is broadly assisted and for several link-state behaviors, it is configurable.
4. Define Network Traffic:
   • In the network, append traffic sources and destinations. Make realistic traffic patterns utilizing OPNET’s application definitions such as FTP, HTTP, and VoIP.
   • On the other hand, utilize custom traffic flows among nodes, which indicating metrics like traffic rate and packet size that will be routed according to the shortest path calculated using OSPF.
5. Customize Link Parameters:
   • Indicate link capacities, delays, and failure situation, for a more in depth replication.
   • It permits to monitor how Dijkstra’s Link-State Routing algorithm recomputes the paths once a link dropped or turn out to be congested, since it actively adapts depends on the link-state updates.
6. Configure Simulation Parameters:
   • Describe the replication duration, for randomization to select a proper seed, and indicate the data collection intervals.
   • Facilitate data collection on parameters related to routing like route discovery time, end-to-end delay, throughput, and OSPF overhead.
7. Run the Simulation:
   • Select the “Run” button for run the replication. Verify for errors or warnings before executing to make sure that configuration is correct.
   • OPNET will utilize the Dijkstra algorithm within OSPF computing the shortest paths and update routes depends on any modifications within network topology, during the simulation.
8. Analyze the Results:
   • Monitor and interpret outcomes utilising the analysis tools within OPNET. Crucial performance parameters to analyse involve:
     • Convergence Time: How rapidly the network adjusts to topology modifications.
     • Packet Delivery Ratio: The ratio of packets is effectively delivered.
     • Throughput: The successful message’s rate delivery through an interaction channel.
     • End-to-End Delay: The average duration for packets to navigate the network.
     • Routing Overhead: The control message overhead launched by OSPF updates.

With the help of this manual, we learnt how to set up and create a network topology and how to analyse the outcomes for Dijkstra’s Link-State Routing projects that were simulated using OPNET. We can deliver further elaboration depends on your requests.
