Network Infrastructure

One Internet Connection Should Not Be One Point of Failure

Engineer multi-provider WAN, failover, policy routing, application-aware routing, SD-WAN, LTE/5G backup, and satellite fallback where justified.

Connectivity Model

Paths, boundaries, and failure domains

Keep critical sites connected through provider failure, degraded links, regional disruption, and application-specific routing needs.

Where resilience and segmentation must be explicit

Keep critical sites connected through provider failure, degraded links, regional disruption, and application-specific routing needs.

Network Surface Where resilience and segmentation must be explicit
  1. 01 Multi-provider WAN Normal business traffic
  2. 02 Failover Automatic failover
  3. 03 Policy routing Degraded continuity
  4. 04 Application-aware routing Controlled failover exercises
  5. 05 SD-WAN Normal business traffic
  6. 06 LTE/5G backup Automatic failover

Design a Resilient WAN

Start with the site, path, outage pattern, or access requirement. HRHK can translate connectivity constraints into segmented, observable, and recoverable network architecture.
