== Scope ==
 +
<!-- Project scope.  The project scope should be well defined.  It should be possible from the scope to crisply answer whether something belongs or not within the scope of this particular project.  Scopes should not be overly broad.  A Project scope must also lie within the overall scope set by the board for projects in fd.io:
 +
    - IO
 +
        – Hardware/vHardware <-> threads/cores
 +
    - Processing
 +
        - Classify
 +
        - Transform
 +
        - Prioritize
 +
        - Forward
 +
        - Terminate

    - Management Agents

Sweetcomb's main responsibility is to enable communication between northbound interfaces and VPP's management APIs, performing all necessary translations in the background. It is important to note that many features and utilities will be reused from open source projects and tools (e.g. netopeer2, Sysrepo) and will not be a direct part of Sweetcomb. This section is splitted into 2 sections: in-scope and out-of-scope to clearly define what is developed as part of Sweetcomb project and what will be just reused from other projects (or where Sweetcomb relies on other projects).

Intro

Sweetcomb is a management agent written in C that runs on the same host as a VPP instance, and exposes yang models via NETCONF, RESTCONF and gNMI to allow the management of VPP instances.

Sweetcomb work as a plugin (ELF shared library) for sysrepo datastore.

Scope

Sweetcomb's main responsibility is to enable communication between northbound interfaces and VPP's management APIs, performing all necessary translations in the background. It is important to note that many features and utilities will be reused from open source projects and tools (e.g. netopeer2, Sysrepo) and will not be a direct part of Sweetcomb. This section is splitted into 2 sections: in-scope and out-of-scope to clearly define what is developed as part of Sweetcomb project and what will be just reused from other projects (or where Sweetcomb relies on other projects).

Sweetcomb project scope:

  • Translation layer between VPP management and Yang based data structures
    • Must support all features of VPP exposed in its APIs in an extensible manner
  • Write YANG models for VPP specific features
  • Expose APIs to integrate with other open source projects
    • Base implementation of all generic southbound interfaces leverage VPP-VAPI
    • expose APIs to integrate with SD-WAN control plane, such as SDN Controller.
    • expose APIs to integrate with Routing Daemon, such as FRR.
    • expose APIs to integrate with IKE protocol, such as strongswan.
    • expose APIs to integrate with DPI control plane, such as nDPI.
    • expose APIs to integrate with BRAS control plane, such as OpenBRAS.

Out of scope:

  • VPP API (VAPI or VOM)
    • VAPI: C APIs for VPP, allowing C-based applications to interact with VPP is out of scope of Sweetcomb project and is part of the base VPP project.
    • VOM: C++ based API offering storage of networking objects
  • Writing yang models for VPP management
    • IETF and Openconfig YANG models are used as much as possible
    • For missing features, we rely on Honeycomb YANG models
  • Compliancy with YANG models, storage of YANG tree
    • Provided by sysrepo project and libraries it uses
  • Integration/performance testing
    • Complex integration or performance tests are out of scope of Sweetcomb project and are part of CSIT project
  • Any other application based on top of Sweetcomb is out of scope of this project and needs to be hosted in a dedicated project inside or outside of fd.io

Releases

Sweetcomb releases are based on VPP version numbers as sweetcomb uses VPP API which is not backward compatible.
