Definition

A carrier network is a telecommunications network operated by a service provider to deliver customer traffic across wide-area infrastructure.

Key Points
  • Built for managed service delivery, not just best-effort connectivity.
  • Combines access, backhaul, transport, and core functions under one operational model.
  • Must maintain service assurance, scale, and resilience under load.
  • Provides the foundation for mobile, fixed, and wholesale connectivity services.
Concept

It is the provider-owned and provider-managed network layer that interconnects access networks, transport systems, and core services.

Explainer

Carrier networks are defined by operational responsibility and service-grade requirements. The term is broader than a single access technology and broader than a single core platform.
