Dynamic Service Extensibility through Programmable Network in a Mobility Context

Abstract

The proliferation of mobile computing devices over the past decade has expedited researches on mobility services and architecture, namely, Mobile IP, Mobile QoS and multimedia content adaptation for limited wireless bandwidth. However, to our knowledge, all of the currently proposed mobility service architectures, such as [3], [7], are restricted to operate within one administrative domain, or a confederation of administrative domains. This paper addresses the following issue: Is it possible to remove the boundary that confines the closeness in service operating environment and be able to extend application- level services in a dynamic, on-demand manner over mobility architecture such as Mobile IP [1]? We present the Dynamic Extensible and Programmable Service Architecture Mobile extension, (DEEPSEA-M), which is aimed at accomplishing the above. Within the mobility context, we discuss issues regarding service extension, security, maintenance and teardown control, as well as detailing an implementation design in achieving DEEPSEA-M framework.
