m3m3 An Adaptable Enterprise Architecture for Mobile Computing

Overview 4 m 3 – Why we do it 4 m 3 – Platform 4 m 3 – Project Status

Computing and Communications Growth 4 Performance / Price x2 every 18 months (100x per decade) –Aggregate bandwith x2 in 8 months –1.5 billion mobile phones in the next few years –Devices / Users >> 1 4Increasing number of Internet transactions

Mobile constraints 4 Bandwith fluctuation 4 Capabilities variation 4 Disconnection (voluntary) 4 Radical Heterogeneity 4 Hostile environments

Constraints will stay – will they? 4 gaps coverage 4 wireless bandwith < wired bandwith 4 mobile cababilities << fixed capabilities Bet: “Adaptable Internet Service/Application Driven Wireless Networks”

The Goal Maximize the Enterprise productivity while minimizing constraints brought by mobility

Research Vision 4 Not just about making applications mobile But 4 Allowing enterprise applications to be deployed (used) in many different environments effectively. 4 Innovative workplace technologies and concepts in a variety of mobile work situations. 4 Demonstrate reference models, architectures and technologies that enable mobile enterprise roles to co-operate.

Platform Model M3 Focus Enterprise Applications Network Externally provided Loca- tion Trans- action Adaptability Manager Policy Manager Mobile Enterprise Architecture Description Interface Tra- ding Notifi- cation Context Manager Service Interface Avai lability WAP Enabler JINI Enabler Security Manager Blue- tooth Enabler HTTPS Enabler Network Programming Interface

Context Manager 4 Observation and reporting of information relevant to the current “context” of devices, networks, users, applications 4 Based on Composite capability/preference profile (CC/PP) –Repository in RDF/XML (standardized vocabularies, extensible, indirect references) –Context exchange protocol

Adaptability Manager 4 Adapt to context changes –Security, Presentation, Usage of Network, Enterprise Application specifics... 4 Changes in context are mainly due to –mobility of users, computers –disconnection 4 Adaptation can be handled externally or internally for an application

Policy Manager 4 Enforces “dynamic” enterprise policy specifications affected by mobility –Obligation, prohibition, permission 4 Takes into account –Standards like RM-ODP –Existing Policy Manager

Security Manager 4 Enable security as intended and required by an application irrespective of the –environment –device 4 Provide an application infrastructure to leverage technologies such as WAP- WTLS 4 Enables the maximum security available on a device –e.g., GSM phones with WAP and BlueTooth – enable the best 4 Close management of security aspects –e.g., Certificate management [issue & expiry control]
