Intro

Hc2vpp is a java-based agent that runs on the same host as a VPP instance, and exposes yang models via netconf or restconf to allow the management of that VPP instance from off box. The Hc2vpp project used to be part of honeycomb.

Process of spiting honeycomb project into generic (honeycomb) and vpp related (hc2vpp) parts was done during 1.17.01 release.

Scope

Hc2vpp's main responsibility is to enable communication between it's northbound interfaces and VPP's management APIs, performing all necessary translations in the background.

This section is divided into 2 sections: in-scope and out-of-scope to clearly define what is developed as part of Honeycomb project and what will be just reused from other projects (or where hc2vpp relies on other projects).

**Hc2vpp project scope: **

  • Yang models for VPP management

    • Configuration data
    • Operational data

  • Translation layer between VPP management and Yang based data structures

    • Must support all features of VPP exposed in its APIs in an extensible manner

**Out of scope: **

  • Northbound interfaces:

    • generic NETCONF/RESTCONF/BGP support is part of honeycomb project

  • Vpp-japi

    • Java APIs for VPP, allowing JVM to interact with VPP is out of scope of Honeycomb project and is part of the base VPP project

  • Yang parser

  • Integration/performance testing

    • Complex integration or performance tests are out of scope of Honeycomb project and are part of CSIT project

  • Any other application based on top of Honeycomb is out of scope of this project and needs to be hosted in a dedicated project inside or outside of fd.io
