The purpose of Yate's design is to provide an extensible telephony engine. Holding the base code as simple as possible and adding functionality as needed allows one to find the best balance between desired functionality, performance and stability.
The architecture of Yate is based on a message passing system. The architecture can be divided into four main parts as you can see bellow.
Contents |
Core
The Core where encapsulations for sockets, threads and others primitives can be found.
Engine
The engine holds the base C++ classes of Yate and connects together all components. There is a diagram showing how all components interact.
Modules
Most real functionality is provided by modules loaded at runtime. These can be dynamical libraries loaded as plugins in the engine or external applications started by a specific module (extmodule) that allows them to talk to the engine and other modules.
Messages
The signaling between Yate modules (either plugins or external modules) is performed by using messages. They provide extensibility, customization and technology independence. Each module that needs something from another or tries to notify about some event creates and emits a message. The message flows through the Engine which tries to deliver it to the proper target.
