Please assist me in drawing a diagram for virtualized network infrastructure

The diagram represents a high$-$level overview of the virtualized network infrastructure designed to mitigate network congestion. It includes the following components:

a$)$ User Layer

$$ End$-$User Devices:

o Icons representing desktops, laptops, tablets, and smartphones.

o Connected to the network via wired or wireless connections.

b$)$ Access Layer

$$ Access Switches $($Edge Switches$)$:

o Multiple switches connecting end$-$user devices to the network.

o Configured with Virtual LANs $($VLANs$)$ to segment network traffic.

$$ VLAN $10$: For administrative staff.

$$ VLAN $20$: For sales department.

$$ VLAN $30$: For manufacturing operations.

o Wireless Access Points $($WAPs$)$:

$$ Connected to access switches for wireless device connectivity.

o Connection Representation:

$$ Lines from user devices to access switches.

$$ Different colors or labels to represent different VLANs.

c$)$ Aggregation Layer $($Distribution Layer$)$

$$ Aggregation Switches:

o Connect multiple access switches.

o Implement Virtual Switching Instances $($VSIs$)$ or Virtual Switches.

o Host Network Functions Virtualization $($NFV$)$ Components:

$$ Virtual Firewalls: For security between VLANs.

$$ Virtual Load Balancers: To distribute network traffic.

$$ Virtual Routers: For inter$-$VLAN routing.

o Connection Representation:

$$ Lines from access switches to aggregation switches.

$$ Aggregation switches connected to both access and core layers.

d$)$ Core Layer

$$ Core Switches:

o High$-$capacity switches forming the backbone of the network.

o Provide fast and reliable connectivity.

o Connect to data center resources and external networks.

o Connection Representation:

$$ Lines from aggregation switches to core switches.

$$ Redundant connections to ensure high availability.

e$)$ Data Center

$$ Servers Hosting Virtual Machines $($VMs$)$:

o Represented by server icons with multiple VMs inside.

o Managed by Hypervisors $($e$.$g$.,$ VMware ESXi, Microsoft Hyper$-$V$).$

$$ Software$-$Defined Networking $($SDN$)$ Controller:

o Centralized control plane managing network devices.

o Communicates with switches using protocols like OpenFlow.

$$ Storage Virtualization:

o Storage Area Network $($SAN$)$: For block$-$level storage.

o Network$-$Attached Storage $($NAS$)$: For file$-$level storage.

$$ Network Functions:

o Virtual Firewalls, Virtual Load Balancers, VPN Gateways.

o Deployed as software appliances within the virtual environment.

$$ Connection Representation:

o Lines from core switches to data center components.

o Arrows indicating data flow between servers, storage, and network devices.

f$)$ Cloud Services

$$ Public Cloud Integration:

o Icons representing cloud service providers $($e$.$g$.,$ AWS, Azure$).$

o Hybrid Cloud Model:

$$ On$-$premises infrastructure connected to public cloud resources.

$$ VPN Tunnels or Direct Connect links for secure communication.

$$ Connection Representation:

o Lines from core switches to cloud icons.

o Bidirectional arrows showing data exchange.

g$)$ Management and Orchestration

$$ Management Tools:

o SDN Orchestrator: For network provisioning and policy enforcement.

o NFV Orchestrator: For deploying and managing VNFs$.$

o Monitoring Systems: For performance and security monitoring.

$$ Connection Representation:

o Lines connecting management tools to SDN Controller and network devices.

h$)$ Security Components

$$ Virtual Firewalls:

o Placed between network layers to inspect and filter traffic.

$$ Intrusion Detection and Prevention Systems $($IDPS$)$:

o Monitors network traffic for malicious activities.

$$ Access Control Lists $($ACLs$)$:

o Implemented on switches and routers to control traffic flow.

$$ Connection Representation:

o Shield icons indicating security functions.

o Lines showing points of enforcement.

Visual Layout:

$$ Bottom Layer: User devices connected to access switches.

$$ Middle Layers: Access switches connect to aggregation switches, which in turn connect to core switches.

$$ Top Layer: Core switches connect to data center resources and cloud services.

$$ Hierarchical Structure: Clearly defined layers representing the network hierarchy.

$$ Color Coding: Different colors used for VLANs, network layers, and types of connections.

$$ Labels: Each component is labeled for clarity $($e$.$g$.,$ "Access Switch," "Aggregation Switch," "Core Switch"$).$
