To simulate distance-vector routing within OPNET Modeler that needs to utilize protocols according to the distance-vector algorithm, like RIP (Routing Information Protocol). Distance-vector routing depends on the routers distributing its distance vectors or routing tables along with neighbors to determine the shortest path according to a certain metric such as the number of hops. Given below is a guide to configure a distance-vector routing simulation in OPNET:
Steps to Simulate Distance Routing Projects in OPNET
- Set Up the OPNET Project
- To make a new project that concentrate on distance-vector routing in OPNET Modeler.
- Describe the workspace and for monitoring parameters such as convergence time, path stability, and hop count, defines the simulation metrics like replication duration and parameters.
- Design the Network Topology
- Make a network including routers, switches, and endpoint nodes such as clients and servers.
- Make sure that several paths exist among routers permitting the distance-vector protocol to chosen the paths according to hop count.
- Append redundancy by way of configuring numerous paths to the similar destination, which permitting the protocol to actively select the routes depends on the shortest path or hop count.
- Enable RIP (Routing Information Protocol)
- Routing Information Protocol is one of the most general distance-vector protocols and its functions utilizing hop count like a metric:
- In property of each router, facilitate the RIP like the routing protocol.
- Set up RIP-specific metrics:
- Update Interval: For RIP, configure the interval to transmit the updates (per 30 seconds).
- Maximum Hop Count: RIP normally contains a maximum hop count of 15 to avoid the routing loops.
- Route Timeout: For routes, configure a timeout, from the routing table after which they are eliminated if updates are not obtained.
- Configure Link Characteristics
- Configure link properties, like bandwidth, delay, and error rates, replicating realistic network conditions.
- Routes are selected depends on the hop count, thus the protocol disregards other link parameters such as bandwidth or delay, for RIP. But, these settings will even influence the data transmission performance.
- Define Application Traffic
- Configure application traffic among clients and servers replicating data flows, which utilize the RIP-configured routes:
- Describe traffic patterns like HTTP requests, FTP sessions, or voice-over-IP (VoIP) in Application Config and Profile Configs.
- Connect profiles to client and server nodes making data flows and then monitor how RIP chooses shortest path according to the hop count.
- Enable Data Collection for Distance-Vector Metrics
- Allow data collection parameters for RIP-specific metrics:
- Route Changes: Monitor the routing table updates then modifications in response to network changes.
- Convergence Time: For every router, we can estimate the time it takes to attain a stable state after topology modifications.
- Hop Count: Observe the number of hops making sure that RIP is choosing shortest path depends on the hop count.
- Link Utilization: To know how successfully the protocol delivers traffic, monitor link usage.
- Run the Simulation
- Begin the replication then observe how the RIP protocol handles the routes according to hop count.
- Monitor periodic routing table updates among routers since they swap distance vectors also choose the shortest paths.
- Analyze Results
- After the replication accomplishes, to estimate the distance-vector routing performance utilizing OPNET’s analysis tools:
- Convergence Time: For the network, observe after a topology or network load change how long it takes to attain a stable routing state.
- Path Selection: Check that paths are chosen depends on the shortest hop count.
- Route Stability: After link or node failures, verify the frequency of routing updates to estimate the stability.
- Latency and Packet Delivery: Examine end-to-end latency and packet delivery rates together with the chosen routes that can support to detect delays by reason of indirect paths.
