Architecture of an IKEv2 Protocol Implementation

In this paper we describe the architecture of an IKEv2 protocol implementation. The architecture has been designed with the aim to make the implementation meet a number of good characteristics: to be as fast as possible, scalable, easy to understand and enhance, as well as portable across different operating systems and processor architectures. As a byproduct we endeavored to specify an architectural pattern that might be used to build other, similar network protocols. In order to make this pattern even more attractive, parts of the architecture are separated as a generic software framework, thus allowing reuse of the code base. The implementation itself is written in the C programming language but borrows some of the concepts from object oriented programming. More specifically, it both enforces the access to private data structures of the different modules and uses messages, i.e. objects, to communicate different events among subsystems.
