Design

DigSiNet follows a modular design, consisting of three main parts:

• Controllers

• Interfaces

• Applications

Interfaces

Interfaces sit between controllers and the real network and are responsible for retrieving and manipulating information from on the real network. DigSiNet is using gNMI as the primary communication protocol, but implementing other protocols is possible by subclassing the Interface class in interfaces/.

Controllers

Controllers translate an abstract, declarative specification of a real network into a suitable topology for a given network emulation tool. Currently, DigSiNet only supports topologies in Containerlab, but implementing other network emulators is possible via the exposed topology builders in builders/.

Applications

Applications can consume information from one or multiple siblings to gain insights on the network. They are also able to leverage gNMI to perform changes on the real network based on insights gained over siblings. An interface for writing custom applications is provided in apps/.
