The "interchange." This layer implements policies, routing between VLANs (Virtual Local Area Networks), and security filtering. It bridges the high-speed core with the user-facing access layer.
A "solid" design anticipates growth. This involves using modular hardware and a structured IP addressing scheme (IPv6 or CIDR) that allows for easy expansion without reconfiguring the entire system. network design
Modern networks assume the perimeter is porous. Design-level security includes: The "interchange
Not all data is equal. A good design prioritizes time-sensitive traffic—like Voice over IP (VoIP) or video conferencing—over standard web browsing to ensure clear communication. 3. Security by Design The "interchange." This layer implements policies
