Introduction

YANG Suite consists of several Django applications with most working independently.

The core applications consist of:

  • yangsuite - UI routing, central logging, general utility APIs, google analtics reporting, and user and plugin management
  • yangsuite-devices - Device management
  • yangsuite-filemanager - YANG file and YANG set management
  • yangsuite-yangtree - Converts YANG files to JSON objects for general use
  • yangsuite-netconf - Communicates with devices using NETCONF protocol

Optional plugins consist of:

  • yangsuite-coverage - Analysis of YANG files presenting customizable spreadsheets and diffs
  • yangsuite-grpc-telemetry - Model Driven Telemetry listener for device telemetry streams
  • yangsuite-gnmi - Communicates with devices using gNMI protocol
  • yangsuite-restconf - Communicates with devices using RESTCONF protocol
