Network Architecture & Design

A well-designed network is the foundation of reliable IT operations. This guide covers the core components, design principles, and protocols ALCO USA uses to build secure, scalable networks.

Core Components

• Routers: direct traffic between networks
• Switches: connect devices within a network
• Firewalls: enforce security policies and filter traffic
• Load balancers: distribute traffic for performance and availability
• Access points: provide wireless connectivity

Design Principles

• Topology: choose the right layout (star, mesh, hybrid) for the environment
• Redundancy: eliminate single points of failure
• Scalability: design for future growth
• Security: segment networks and apply defense in depth
• Performance: minimize latency and plan for bandwidth needs

Key Protocols

• TCP/IP: the foundation of network communication
• DNS: resolves domain names to IP addresses
• DHCP: automatically assigns IP addresses
• VLAN: segments traffic for security and organization
• VPN: secures remote connections

Best Practices

1. Document the network topology and keep it current
2. Segment networks to contain and limit threats
3. Build in redundancy for critical paths
4. Monitor traffic and set performance alerts
5. Review and update the design as needs change
