Core Layer: The backbone of the network, connecting all major nodes. We recommend high-speed core switches with advanced routing capabilities to handle the increased traffic.

Distribution Layer: This layer aggregates data from the access layer and connects to the core layer. It provides policy-based connectivity, routing, and QoS (Quality of Service).

Access Layer: The edge of the network, connecting end devices such as workstations, printers, and access points. We recommend using managed switches to ensure security and efficient traffic management.

3. IP Addressing Scheme:

A well-structured IP addressing scheme is crucial for network scalability and management. We propose using a Classless Inter-Domain Routing (CIDR) approach to allocate IP addresses efficiently. This involves:



Dividing the network into subnets based on departments (e.g., HR, Sales, IT).

Allocating a separate subnet for remote workers using VPN (Virtual Private Network) technology.

Implementing DHCP (Dynamic Host Configuration Protocol) for dynamic IP allocation and easy management.

4. Security Measures:

Security is paramount in network design. We propose the following measures to secure XYZ Corp's network:



Firewalls: Deploying firewalls at the network perimeter to monitor and control incoming and outgoing traffic.

Intrusion Detection and Prevention Systems (IDPS): Implementing IDPS to detect and prevent malicious activities.

Access Control Lists (ACLs): Configuring ACLs on routers and switches to restrict unauthorized access.

VPNs: Setting up VPNs for secure remote access.

Network Segmentation: Segmenting the network into VLANs (Virtual Local Area Networks) to isolate sensitive data and reduce the attack surface.

5. Redundancy and High Availability:

To ensure network availability, we incorporate redundancy at critical points:



Redundant Core Switches: Using multiple core switches to provide failover capabilities.

Link Aggregation: Implementing link aggregation to combine multiple physical links into a single logical link, increasing bandwidth and providing redundancy.

Backup Power Supplies: Using uninterruptible power supplies (UPS) and backup generators to keep the network operational during power outages.

6. Integration with Cloud Services:

XYZ Corp uses various cloud services for storage, collaboration, and applications. We design the network to integrate seamlessly with these services:



Direct Cloud Connectivity: Establishing direct connections to cloud providers for improved performance and security.

Hybrid Cloud Solutions: Designing a hybrid cloud architecture that combines on-premises and cloud resources, providing flexibility and scalability.

Implementation and Testing:

After finalizing the design, we proceed with the implementation, which includes configuring network devices, installing necessary software, and setting up security measures. Comprehensive testing is conducted to ensure the network meets the design specifications and performs optimally under different scenarios.
