SMF Architecture

The SMF network function consists of loosely coupled microservices together. The microservice decomposition is based on a three-layered architecture as illustrated in the following figure.

SMF 3-Layered Micro Services Architecture

Following are the three layers of the SMF architecture:

  • Layer 1—Protocol and Load Balancer services (Stateless)

  • Layer 2—Application services (Stateless)

  • Layer 3—Database services (Stateful)
