To simulate an IPv4 protocol projects using OPNET, it has comprises to configure a network, which IPv4 used for addressing and routing through devices also to set up network modules handling IPv4-based interaction. IPv4 is the basis for numerous Layer 3 protocols that contains routing protocols such as OSPF, RIP, and BGP. We will guide you through simulation method for configuring and analyzing an IPv4-based network simulation in OPNET:
Steps to Simulate IPv4 Protocol Projects in OPNET
- Initialize the Project and Define Network Topology
- Create a New Project: Launch OPNET and initiate a new project that choosing a topology, which matches the replication aims like LAN, WAN, or MAN.
- Define the Network Layout: Model a topology including core and edge routers, switches, and end devices like servers, workstations. In the network, we can make subnets that signifying diverse departments, positions, or functional areas.
- Add and Configure Devices for IPv4
- Place Routers, Switches, and End Devices: Append routers handling the inter-network traffic, switches to manage the LAN traffic, and end devices intended for experimenting data transmission. Associate them to make subnets or separate LAN segments as required.
- Assign IPv4 Addresses and Subnet Masks:
- Allocate the single IPv4 addresses and subnet masks for every device, which segmenting the network within manageable segments.
- Make certain that an appropriate IP addressing scheme followed by address for simple identification and routing through the network.
- Enable IPv4 Routing on Routers
- Configure Routing Protocols: Configure the routers including one or more IPv4 routing protocols to handle the data routing over network segments:
- RIP (Routing Information Protocol): It is optimal for small networks, RIP utilizes distance-vector routing and it contains a maximum hop limit of 15. In smaller Subnetworks, we can configure RIP on routers.
- OSPF (Open Shortest Path First): Set up OSPF on routers to make effective link-state-based routes for larger, hierarchical networks. Describe the OSPF areas to divide the network, which enhancing its performance and scalability.
- EIGRP (Enhanced Interior Gateway Routing Protocol): EIGRP can set up along with parameters like bandwidth and delay, for medium to large networks. Set up EIGRP on routers in an AS (Autonomous System).
- BGP (Border Gateway Protocol): Facilitate BGP on the border routers, for inter-domain routing. Allocate an AS numbers and also set up peering among the routers within diverse ASes handling external IPv4 traffic.
- Static Routes (Optional): Insert static routes for certain paths on the routers, particularly if require exact control across specific routes otherwise require to replicate the fixed paths among segments.
- Define Traffic Models
- Application Traffic: Configure application traffic flows, which signify real-world information like HTTP, FTP, VoIP, and Email. Every traffic type will be made IPv4 packets that permitting to monitor the packet handling and IPv4 routing.
- Traffic Patterns:
- Intra-Subnet Traffic: In the similar subnet, set up traffic flows to monitor the LAN interaction that depending on local IPv4 addressing.
- Inter-Subnet Traffic: Configure traffic flows through subnets, which needing routers to handle the inter-network routing and it permitting to experiment the IPv4 routing protocol’s exactness and effectiveness.
- Simulation Parameters and Scenario Setup
- Set Simulation Duration: Select a simulation time which is sufficient to monitor the routing table convergence, network stabilization, and traffic flow patterns.
- Create Multiple Scenarios:
- Network Load Variation: Maximize or minimize traffic loads to estimate on how the IPv4 network handles bandwidth and resources that specifically for high traffic.
- Link Failures and Route Recovery: Replicate the link failures or router outages to examine how rapidly routing protocols adjust and meet in response to topology modifications.
- Dynamic IP Address Assignment: If DHCP is set up then analyse the IPv4 addresses assignment and reassignment to monitor the address management.
- Define Performance Metrics and Data Collection
- Key Metrics for IPv4 Networks:
- Packet Delivery Ratio: Assess the percentage of IPv4 packets effective distributed, estimating network reliability.
- End-to-End Delay: Monitor the entire latency for packets to move from source to destination to show the protocol efficiency.
- Routing Overhead: Observe the control packet load such as RIP updates, OSPF LSAs, or BGP updates are made utilizing routing protocols, which offering insights toward network overhead.
- Routing Table Size: Monitor the routing tables’ size within every router that particularly in networks along with dynamic routing protocols.
- Link Utilization: Observe the significant links usage to monitor on how effectively IPv4 routing delivers the traffic load.
- Route Convergence Time: For routing protocols, compute the duration to reconverge after a modification to deliberate the protocol responsiveness.
- Data Collection Setup: Record parameters relevant to IPv4 traffic that concentrate on delivery ratio, delay, routing overhead, and convergence using OPNET’s data collection tools.
- Run the Simulation and Analyze Results
- Execute the Simulation: Now, execute the replication then observe IPv4 traffic flow through devices. Focus on how routing protocols handles the route discovery, data sending, and failover once there are network modifications.
- Analyze Results: Make plots for parameters such as packet delivery ratio, end-to-end delay, routing overhead, and convergence times utilizing OPNET’s analysis tools. Calculate the IPv4 network’s performance then detect areas in which network resources probably under or overutilized.
