To simulate a Fully Connected Topology using OPNET that includes configuring a network in which every node contains a direct link to every other node. Fully Connected Topology is also called as a full mesh, information can move natively among any two nodes without needing intermediate nodes in the topology. This structure offers maximum redundancy, reliability, and minimal data latency however it also needs a large number of links that can turn out to be costly and complex for larger networks.
This guide will teach you how to simulate the fully connected topology in OPNET:
Steps to Simulate Fully Connected Topology Projects in OPNET
- Set Up OPNET Environment
- Launch OPNET Modeler, make a new project, and then name it a little bit relate like “Fully Connected Topology Simulation.”
- Set up the workspace in the network to put up a layout in which every single node will directly associate to every other node.
- Add Nodes for the Fully Connected Topology
- Add Devices:
- Append the devices we need to link like workstations, servers, routers, or switches.
- Select the number of nodes we require for the simulation. Monitor the number of connections grows fastly because nodes are inserted since each node need to associate directly to every other nodes.
- Arrange Nodes:
- In a circular or grid pattern, locate the nodes creating the fully connected layout simpler to envision and handle.
- Configure Links to Create the Fully Connected Structure
- Use Point-to-Point Links:
- Link each node to every other node using point-to-point links in the network.
- Link Type and Speed:
- Select link types according to the network needs. Options contain:
- Ethernet (e.g., 10 Mbps or 100 Mbps) for LAN connections.
- Gigabit Ethernet for high-speed connections.
- Fiber Optic Links for large-scale or high-capacity networks.
- Select link types according to the network needs. Options contain:
- Full-Duplex Configuration:
- For full-duplex communication, we make sure that each link is set up, to prevent information to be transmitted and received concurrently at each link.
- Link Properties:
- Set up transmission speeds and latency depends on the needs of the network configuration for each link. Higher speeds can be minimized the latency and enhanced data flow over the fully connected topology.
- Assign Applications and Configure Traffic Patterns
- Describe the kinds of applications each node will utilise in Application Configuration. Instances are comprise of:
- HTTP or HTTPS for web traffic.
- VoIP for real-time communication.
- FTP for file transfers.
- Video Streaming for high-bandwidth scenarios.
- Allocate applications to certain nodes utilizing Profile Configuration. Set up each node to transmit and receive traffic to/from other nodes, to mimic several application situations through the fully connected network.
- Enable Data Collection for Monitoring and Analysis
- Configure data collection parameters at every links and nodes, which concentrating on throughput, link utilization, and latency:
- Throughput: In the fully connected topology, assess data throughput through each link and node examining how effectively data flows.
- Link Utilization: Monitor the utilization of every link detecting which links manage the higher loads and can experience congestion.
- Latency and Delay: We can observe end-to-end latency among nodes knowing data travel times through the fully connected network.
- Packet Loss: Estimate the packet loss identifying any transmission issues, particularly in high-traffic situations.
- Configure Node and Link Properties
- Node Role:
- In Profile Configuration, set up every node like a sender, receiver, or both, according to the applications are allocated.
- Traffic Generation Parameters:
- Configure traffic generation metrics depends on the anticipated load. For instance, we would set up nodes to intermittently transmit HTTP requests or endlessly download files across FTP mimicking normal network usage.
- Run the Simulation
- Execute the replication, to permit data to flow among every set of nodes across its direct links in OPNET.
- In the network, monitor network behavior with data flow, link utilization, and performance parameters through every connections.
- Analyze Results
- Examine the performance of the fully connected topology utilising OPNET’s analysis tools:
- Throughput Analysis: Confirm throughput over each link monitoring if data transmission converges the performance needs of network.
- Latency and Delay: Estimate delays over the network. Fully connected topologies commonly offer low latency by reason of direct links, however observing will support to check it.
- Link Utilization: Monitor the utilization of each link knowing if specific links take more traffic than others.
- Packet Loss and Reliability: Analyse packet loss over links that particularly for links managing high loads, making sure data reliability thorugh the network.
- Experiment with Different Configurations
- Customize the network settings to experiment diverse situations and sets up:
- Increase the Number of Nodes: Insert additional nodes to the network observing how performance ascends. Observe this maximizes the number of links crucially.
- Higher Traffic Loads: Maximize the data rates of applications mimicking heavier loads at the network and then monitor how the fully connected topology manages the high-demand situations.
- Different Link Speeds: Observe how performance parameters such as latency and throughput change to test with different link speeds that specifically on high-traffic links.
- Introduce Fault Tolerance and Redundancy Testing (Optional)
- Link Failure Simulation:
- For the moment detach one or more links and then monitor how it impacts the performance of network. Nodes would even be equipped to interact across alternative links, even though latency probably maximize in a fully connected topology.
- Load Balancing:
- Monitor if traffic is equalized through several paths and links. The fully connected topology offers inherent redundancy, thus traffic would deliver over the links based on the traffic load and routing protocol.
Overall, we had exposed an ordered procedure to replicate and examine the Fully Connected Topology Projects utilizing OPNET tool. Likewise, we will offer further insights and also extend it, if required.
