 ## What is AppNet?
 
 AppNet is a framework designed for constructing high-performance application networks for microservices. At its core, AppNet offers a high-level abstraction that facilitates the creation of expressive and performant application networks. Users can define rich, possibly stateful, layer-7 (RPC) processing through match-action rules. AppNet's compiler compiles these specifications and generates high-performance code by optimizing where and how to execute different RPC processing functions.

 ## Architecture Overview

-AppNet consists of three main components - the AppNet program, the control plane and the data plane. TThe AppNet program orchestrates the network functionality among microservices through a sequence of elements, detailing each element with match-action rules that govern RPC content and element state.

 The control plane includes a compiler that processes RPC definitions and chain specifications to produce code modules and a controller has global knowledge (acquired via cluster managers such as Kubernetes) of the network topology, service locations, and available AppNet data plane processors. It provisions network processing on available processors.
