In order to untie entities, applications and devices, CLOAK introduces a P2P overlay architecture and redefines the notion of a session. A session is a communication descriptor that contains everything needed for linking entities, applications and devices together in a flexible way. A session represents the identity and the management information of a given communication. Thus the lifetime of a communication between several entities is equal to the lifetime of its corresponding session. A device can move or be changed for another without terminating the session. Similarly, an application can be changed for another if deemed appropriate or even moved (i.e. mobile code) also without terminating the session. Finally entities can move or change (i.e. be transferred to another entity) without terminating the session if this is appropriate for a given communication. We can see that in our new architecture, entities, applications and devices are loosely bound together during a communication and all the movements and changes of devices, applications and entities are supported. To be able to implement our notion of session, we need to introduce several new layers of identifiers in order to decouple lower layers (devices) from middle layers (entities) and from higher layers (applications). Hence the name CLOAK given to this project. We add naming layers above the existing ones in order to give abstract names to objects such as entities and devices. Thus we lay a cloak on the current Internet architecture.
