To Simulate a WAN (Wide Area Network) protocols in OPNET has involves a configuration for network with WAN elements like as routers, switches, and end devices to setting it to utilized a characteristic of WAN protocols such as a MPLS of Frame Relay or ATM. Here’s a procedure on how to simulate WAN protocols and their behavior in OPNET:
Step-by step to simulate WAN Protocols Projects Using OPNET:
- Initialize the Project and Network Topology
- Create a New Project: Open OPNET to make an innovative project and describe the topology which signifies the WAN setting often utilized to link several geographically distant LANs.
- Define Network Layout: Model a topology with key routers, edge routers, switches, and end-user devices such as workstations, servers. Characteristic WAN configurations that involves a central offices to regional offices and remote branches.
- Add and Configure Network Devices
- WAN Devices: Enhance the applicable connection devices such as routers and WAN switches that help the WAN protocols we needed to replicate such as MPLS routers, Frame Relay switches.
- Assign Roles: Selected the precise routers as edge or main routers with edge routers responsible for network LANs to the WAN and main routers maintain the inter-connectivity within the WAN.
- Select and Configure WAN Protocols
- MPLS (Multiprotocol Label Switching):
- Assist the MPLS on important routers for effective traffic routing across the WAN supporting.
- To setting the MPLS Label Distribution Protocol (LDP) for label assignment and label switching paths (LSPs) to prioritize several kinds of congestion.
- Frame Relay:
- Designed for Frame Relay to setting the Frame Relay switches and routers with the DLCI (Data Link Connection Identifier) and describe the Virtual Circuits (PVCs) for transmissions.
- To configure the Frame Relay parameters metrices such as CIR (Committed Information Rate) and Bc (Burst Committed).
- ATM (Asynchronous Transfer Mode):
- Utilized an ATM switches to setting VPIs (Virtual Path Identifiers) and VCIs (Virtual Channel Identifiers) to define connections.
- TO configure an ATM QoS classes such as CBR (Constant Bit Rate) or UBR (Unspecified Bit Rate) dependent on the application necessities.
- Other WAN Protocols:
- If project utilize the WAN protocols such as PPP or ISDN to setting the corresponding boundaries on routers and describe the connection parameters.
- Define Traffic Models
- Application Traffic: Describe the congestion flows among end devices across several LANs linked by the WAN. A general kind of WAN traffic involves the VoIP, video conferencing, FTP, and HTTP.
- Traffic Patterns: Stipulate the traffic flows among different remote sites to replicate a real-world WAN traffic like as branch-to-branch or branch-to-headquarters data flow.
- Set up Quality of Service (QoS) Policies
- QoS Classes: To configure a QoS policy for traffic prioritization within the WAN. For sample, VoIP traffic can be specified the maximum priority over FTP or web traffic to assure the minimum delay.
- Assign Traffic to QoS Classes: Map precise the application traffic to several QoS classes and enabling which complex services such as video conferencing are prioritized over routine data transmissions.
- Simulation Parameters and Scenario Configuration
- Simulation Duration: To configure the replication simulation duration to follow the connection performance under characteristic WAN consumption.
- Create Multiple Scenarios: To process these environments with various settings like as varying bandwidth and changing traffic loads or introducing faults to validate a protocol behavior under several environments.
- Define Performance Metrics and Data Collection
- Key WAN Performance Metrics:
- Latency: TO calculate the end-to-end latency for packets traveling across the WAN.
- Throughput: To follow the data rates accomplished through WAN connections.
- Jitter: Designed for time-sensitive applications such as VoIP to calculate a jitter to estimate QoS.
- Packet Loss Rate: Regulate the packet loss and particularly in this environment with high traffic loads or network congestion.
- Resource Utilization: Estimate the utilization of WAN connections that could be indicates the bottlenecks.
- Data Collection: To setting an OPNET to log these parameter metrices to concentrating on protocol performance and QoS efficiency in behaviour of WAN traffic.
- Run the Simulation and Analyze Results
- Execute the Simulation: To process the replication to follow the WAN behavior and particularly in according on how the WAN protocol maintains the traffic across network.
- Analyze Results: Utilized an OPNET’s analysis tools to observe results and create reports on latency, throughput, jitter, and link utilization. Relate the several environments to classify the protocol efficiency of different network loads.
From the demonstration, we illustrate the complete simulation setup that will help you to execute and simulate the packet WAN Protocols projects using OPNET tool and also we provide the procedures and their explanation. If you need to know more details regarding this process we will provide it.
