Session layer resurgence: Towards mobile, disconnection- and delay-tolerant communication

Abstract

This paper presents an approach to the problem of facilitating dynamic and secure networking in a highly heterogeneous environment. The proposed design includes new architectural components and functions collected at a separate layer-the session layer-while leaving functionality inside the TCP/IP stack intact. Following an overview of the approach and the underlying principles, it is argued that architectural changes in system design are necessary for a smooth evolution of the Internet in the future. © 2007 IEEE.
