TOVE (Toimialaverkot) Goals

To learn Object-Oriented methods in network programming

To create a flexible framework for network programming

To create a flexible call admission control software for an ATM switch (for network architecture research)

”Support standards - use imagination in areas not standardized”

•Adapter: Connects OVOPS++ world to the “outer world”•Protocol: Context of the protocol (state variables, parameters etc.)•State: Functionality of the protocol (dataless singleton classes)•Mux: Multiplexes connections by session keys extracted from the information chunks•Factory: Creates new Conduit instances when information chunk containing new session key arrives at Mux
