Cisco reference-inspired enterprise architecture model

Global Enterprise Network Architecture.

A full enterprise architecture model spanning global core, regional data centers, cloud, WAN/SD-WAN, campus and branch, remote access, security segmentation, identity, observability, DNS/DHCP/IPAM, partner access, backup/DR, and management planes.

Traffic-flow walkthrough

  • Branch to application — Branches and campuses reach enterprise applications through transport, security policy, and regional data center services.
  • Remote user access — Remote users enter through SASE/ZTNA-style access before reaching protected enterprise resources.
  • Cloud application access — Cloud application paths traverse security policy and controlled connectivity.
  • Data center interconnect — Regional data centers exchange application and replication traffic through controlled interconnects.
  • Internet egress — Internet traffic exits through edge and inspection boundaries.
  • Identity and policy — Identity and access services inform segmentation and authorization decisions.
  • Observability telemetry — Telemetry and security events feed NOC/SIEM observability.
  • Partner / extranet — Partner access is separated from internal enterprise services.
  • Backup / DR replication — Backup and disaster recovery traffic follows controlled replication paths.
  • Management plane — Management and OOB access remain separated from user/application traffic.
