Designing for focuses on creating modular, resilient, and intelligent network systems that align with modern business outcomes. By 2026, the architecture has evolved from basic connectivity to an AI-ready framework that integrates security, automation, and observability directly into the network fabric. 1. Core Architectural Frameworks functional modules (e.g.

: Traditional perimeters have been replaced by Identity-Based Access Control , where security policies follow the user or device regardless of location. Designing for Cisco Network Service Architectur...

: Breaking the network into smaller, functional modules (e.g., Campus, Data Center, WAN) to limit failure domains and simplify upgrades.

: Building security into the initial architecture—using Zero Trust Access and micro-segmentation—rather than adding it as a secondary layer.
