Central Theme
User Space is a significant entity, but isignored in the Internet model
User Space
Kernel Space

Central Theme
To standardize User Space Functionality
Entity layer - A new layer of protocols
Positioned between Transport and IP layers

Motivation
Core Internet architecture has not evolved much.
Lack of support for User-based models
Goals of Pervasive and Ubiquitous computing are only incipiently achieved
Examples: Mobility, Migration, and Multi-device management

Conclusion
Consider the User Space as a significant entity in the Internet model
Introduce the Entity layer of protocols between the Transport and IP layers
Identifier/Interlocutor/Locator split architecture for flexible addressing
Evolution of the Entity layer along with the User’s role in the Internet
