To simulate the Network Layer projects in OPNET, we can concentrate the routing protocols for IP addressing schemes of packet forwarding and quality of service (QoS) management. The following guide outlines how to set up a Network Layer simulation in OPNET.
Steps to Simulate Network Layer projects using OPNET
- Set Up OPNET Environment
- Open OPNET Modeler generate a new project and configure the workspace. Label the project according on we concentrate the analysis like as “Routing Protocol Analysis” or “QoS Management.”
- Choose an appropriate scale for the project and whether it’s a LAN, WAN, or mobile ad hoc network (MANET).
- Design Network Topology
- Builds a network topology have containing the Layer 3 routers and end devices such as workstations, servers, or mobile nodes.
- Connect the devices we routers utilized a wired or wireless connection reliant on the network environment such as Wi-Fi access points for wireless simulations.
- Organize the routers and end devices in a structured topology like as a mesh, star, or hierarchical network that suits a routing protocols at the Network Layer.
- Configure Network Layer Protocols
- Choose the routers and setting the IP layer settings for the Network Layer protocol(s) we need the analysis. About general the Network Layer protocols it includes they are:
- Routing Information Protocol (RIP): setting the routers we utilized the distance-vector routing.
- Open Shortest Path First (OSPF): Usage of link-state routing for intra-domain routing.
- Enhanced Interior Gateway Routing Protocol (EIGRP): Cisco’s improved the distance-vector protocol.
- Dynamic Source Routing (DSR) or Ad hoc On-demand Distance Vector (AODV) for MANETs.
- Configure the protocol parameters metrices for samples the update intervals, hop counts, hello intervals we investigation on how they impact of network performance.
- Set Up IP Addressing and Subnetting
- Setting an IP addresses and subnet masks for every device and router interface. This supports we replicate of consistency packet transferring the route selection according on the IP subnets.
- It analysing their hierarchical routing we set up the IP subnets in a structured manner for reflect the network’s layout.
- Implement Traffic Generation
- Builds a various kind of congestions for follow on how well Network Layer protocols maintains different loads.
- Go to Application Configuration and describing the kinds of congestion such as HTTP, FTP, VoIP, Video Streaming we replicate the diverse network environments.
- In Profile Configuration, allow this application for specific source-destination pairs and we build the consistency of network congestion and estimate the routing effectiveness of various environments.
- Define Network Layer Metrics and QoS (Optional)
- It analysing their QoS we ensure the Quality of Service configure the routers to select traffic kinds. For sample, given the higher priority to VoIP or Video Streaming over HTTP.
- Configure the Differentiated Services (DiffServ) or Integrated Services (IntServ) if OPNET handles this design for our version.
- Collect key metrics, such as:
- End-to-End Delay: Calculate the delay with the network.
- Packet Loss: It specifies the packet drops, often affected through network congestion.
- Jitter: we change the packet delay and signify the real-time applications.
- Route Convergence Time: Duration taken used for routing protocols we stabilize the later topology of variations.
- Throughput: Calculate the effectiveness of data rate and signify the protocol effectiveness.
- Simulate Network Mobility (If Applicable)
- It utilized their mobile nodes or a MANET and set up their node mobility models like as Random Waypoint to validate the routing protocols’ adaptability for varying the topologies.
- Mobile scenarios will be permit for monitor on dynamic route discovery and handling in protocols such as DSR and AODV.
- Set Simulation Parameters
- Describe the replication of time according on expected behaviour of routing protocols for instance longer durations allow for observing route stability.
- Permit the data collection for Network Layer statistics we estimate the protocol performance for follow on their packet transferring behaviour with various traffic loads.
- Run the Simulation
- Start the replication of follow on the Network Layer operations like as route discovery, packet transferring and QoS enforcement.
- OPNET will replicate the packet routing based on the selection of protocols and setting the QoS policies and illustrative on how the packets are forwarded among the network.
- Analyse Results
- Utilized the OPNET’s analysis tools we assign the performance of the Network Layer:
- Routing Convergence and Stability: Checked on how rapidly and consistently routing protocols converge later the topology variations.
- End-to-End Delay and Jitter: Monitor the affect of network size for routing protocol and QoS configure the delay-sensitive traffic.
- Throughput and Packet Loss: Estimate the routing efficiency for particularly below the heavy loads or high mobility.
- Route Path Analysis: see the paths and packets take for assigning the permits protocols are correctly choosing the minimum or optimal paths.
- Experiment with Different Configurations and Protocols
- Efforts the multiple routing protocols such as compare OSPF with EIGRP for view on how they perform in multiple network topologies.
- Research with various traffic loads and designs their estimate of scalability and routing protocols.
- Alter the QoS policies we select the multiple kinds of traffic and follow on their effect of network performance.
We thorough the complete Manual and analysed the simulation process on how the network layer projects will be simulated and using the tool of OPNET framework over network. If you like to know more details regarding this process, we will be offered it.
We are excited to explain how to replicate Network Layer projects using the OPNET tool.

We also take care of IP addressing for packet forwarding and managing quality of service (QoS) really well.
