To simulate a Point-to-Point Topology using OPNET, we need to include configuring a direct, dedicated connection among two nodes that normally to utilize a high-speed link. This topology is simple including only two nodes are associated using a single link, to create it helpful for situations, which need rapid, reliable interaction among two devices like routers, switches, or computers within remote offices.
Below is a series of steps to simulate a point-to-point topology in OPNET:
Steps to Simulate Point-to-Point Topology in OPNET
- Set Up OPNET Environment
- Make a new project then name it something related such as “Point-to-Point Topology Simulation” in OPNET Modeler.
- Set up the workspace signifying a basic network with only two nodes and a direct link associating them.
- Add Nodes for the Point-to-Point Connection
- Add Two Nodes: In the point-to-point topology, insert two devices, which will perform like the endpoints.
- According to the situations, we can select any mixture of nodes like workstations, servers, routers, or switches.
- For instance, if replicating a WAN link among two routers then we utilize two routers like the nodes.
- Configure the Point-to-Point Link
- Directly associate the two nodes to utilize a point-to-point link.
- Link Type and Speed:
- Choose the kind of link depends on the intended speed and transmission medium. General options comprise of:
- Ethernet (e.g., 10 Mbps or 100 Mbps)
- Fast Ethernet (100 Mbps)
- Gigabit Ethernet (1 Gbps)
- WAN links such as T1 or T3 for wide-area networks.
- Choose the kind of link depends on the intended speed and transmission medium. General options comprise of:
- Full-Duplex Configuration:
- For full-duplex communication, make the link is set up to permit data to be transmitted and received concurrently. This setting is normal in most point-to-point configuration and increases performance.
- Assign Applications and Configure Traffic Patterns
- In this topology, describe the kinds of applications and traffic, which will be experimented to utilize Application Configuration. Instance contain:
- HTTP or HTTPS for web-based traffic.
- FTP for file transfers.
- VoIP for real-time interaction.
- Email or Database Access for replicating data retrieval or user access patterns.
- Configure Profile Configuration allocating applications to each node, to indicate which node perform like the sender and which as the receiver.
- For instance, one node should function like an FTP server whereas the other performs as a client accessing files from it.
- Enable Data Collection for Monitoring and Analysis
- Set up data collection at the link and nodes observing network performance:
- Throughput: Estimate data throughput over the link measuring the speed and capacity of connection.
- Link Utilization: Monitor the utilization of the link observing during the simulation how much bandwidth is being utilized.
- Latency and Delay: Observe end-to-end latency among the nodes to know how rapidly data moves over the link.
- Packet Loss: Estimate packet loss identifying any issues along with data transmission, particularly for high-demand applications.
- Configure Node Properties
- Set up role of each node according to the application it is executing in the Node Editor:
- Server Node: Configure one node like a server such as FTP or HTTP server, from the other node to manage requests.
- Client Node: Set up the other node as a client, which transmits requests to or from the server node recoveries data.
- Traffic Generation Parameters:
- In a real situation, configure the traffic generation metrics based on the expected load. For instance, set up the FTP client to occasionally download files or replicate continuous data transmission.
- Introduce Traffic Loads and Adjust Link Capacity (Optional)
- Increase Traffic Load: For applications such as FTP or video streaming, set up higher data rates to experiment how successfully the link executes in heavy usage.
- Link Capacity Adjustments: Test with diverse link speeds like, upgrading from Ethernet to Gigabit Ethernet, monitoring the influence over throughput, latency, and packet loss.
- Run the Simulation
- In OPNET, execute the simulation to permit the two nodes are interacting over the point-to-point link.
- Monitor network behavior that contains data flow, link utilization, and the performance parameters are indicated in the data collection configuration.
- Analyze Results
- Estimate the point-to-point topology’s performance utilizing OPNET’s analysis tools:
- Throughput Analysis: Verify the throughput over the link monitoring for the configured link type if it converges the expected speed.
- Latency and Delay: Estimate the delay within data transmission among the nodes that particularly for real-time applications such as VoIP or video streaming.
- Link Utilization: Examine the utilization rate knowing if the link is being entirely used or if it contains excess capacity.
- Packet Loss and Reliability: Verify for any packet loss that should show a problem including link’s capacity to manage the allocated traffic load.
- Experiment with Different Configurations
- Alter network settings to experiment diverse situations and sets up:
- Higher Traffic Loads: Maximize the data rate of application like to download larger files or to replicate a continuous data stream then experimenting how the link executes in heavier load.
- Change Link Speed: Test with diverse link speeds monitoring how they affect the performance parameters. For instance, changing from 10 Mbps Ethernet to 1 Gbps Ethernet would reduce latency and maximizes throughput.
- Different Application Types: Experiment how different kinds of traffic impact performance utilizing other applications like video conferencing or large data backups.
