Table Type Patterns

Table Type Patterns (TTPs) are the (upcoming) first tangible output from the ONF's Forwarding Abstractions Working Group (FAWG). The goal is to allow for an OpenFlow controller and OpenFlow switch to agree on a set of functionality to help manage the increased diversity made possible with OpenFlow versions 1.1+. While the current focus of TTPs within the ONF is on OpenFlow, these abstractions are the first incarnation of a category of abstractions known as "Negotiable Datapath Models" (NDMs), which are likely to be more broadly useful and inside OpenDaylight they could expand to be used for other protocols. (Note that this project was proposed under the title "Negotiable Datapath Models", based on the anticipated specification title being developed at the ONF. When the ONF changed the title, this project's title change was requested.)

There are currently two major sub-projects: ttp-model and parser.
This consists of a YANG model for a TTP that closely matches the ONF spec and a simple model that allows you to associate zero or one "active TTPs" as well as zero or more "supported TTPs" with a switch.
The parser provides CLI tools to read, write and work with TTPs.
The distribution-karaf and features subprojects are there for building and testing Karaf features so that others can load and depend on TTP functionality easily. The utils subproject contains the common, shared functionality between ttp-model and parser.
