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

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

Entity Layer - Services
Supports the User Space
Enables decoupling of User Space from Host
Separates Mobility from Portability
Provides Interlocutors
Groups processes under their Interlocutor
Supports User’s activities
Supports Sharing and Collaboration

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
