About

In order to verify the clarity and validity of the specification documents, two independent prototypes are implemented. After both prototypes are completed, they are verified by interoperability tests using a test bed. Four different types of tests were conducted and passed.

1. Prototype-A Server to Prototype-B Client
2. Prototype-B Server to Prototype-A Client
3. Prototype-A Server to Prototype-A Client
4. Prototype-B Server to Prototype-B Client
