3 September INBOSA workshop 1 Raul Fonseca, Paulo Marques, Paulo Simões, Luís Silva, João Silva CISUC, University of Coimbra, Portugal Integrating Mobile Agents into Off-the-Shelf Web Servers: The M&M Approach

3 September INBOSA workshop 2 Integrating Mobile Agents into Off-the-Shelf Web Servers: The M&M Approach  M&M Overview  Integrating Mobile Agents into the Jigsaw Web Server  Integrating Mobile Agents into Generic Web Servers  Conclusion

3 September INBOSA workshop 4 The M&M Aproach

3 September INBOSA workshop 5 The M&M Aproach HOST AHOST B other app objects Application B other app objects Application A Middleware Mobility Components

3 September INBOSA workshop 6 M&M Main Features  No agent platforms: the agents arrive and departure from the applications  Applications become agent-enabled by using binary software components (JavaBeans and ActiveX)  Easy to program (Visual Builder Tools)  Users do not see agents and do not manage platforms  Security is integrated into the app security framework  Agents can be application specific  Agents are able to interact with applications written in any language (ActiveX support)  Only the required components are included in each application

3 September INBOSA workshop 7 Integrating M&M into Web Server: Requirements  Agents should be able to behave as a Web resource  The agents should be able to query local information on the server  Agents should be able to perform management operations on the web server

3 September INBOSA workshop 8 Related work  Web server built on top of an agent platform  Standard mobile agent platform side-by-side with the web server

3 September INBOSA workshop 9 Integrating M&M into the Jigsaw Web Server  What is Jigsaw and main relevant features  Why Jigsaw for the first aproach

3 September INBOSA workshop 10 Integrating M&M into the Jigsaw Web Server

3 September INBOSA workshop 11 Problems to be addressed  The aproach was not general and was not applicable to other web servers;  Security concerns;  The way the wrapper was interacting with the agents was not the most appropriate one

3 September INBOSA workshop 12 Integrating M&M into Web Servers: The Mobility Servlet Container

3 September INBOSA workshop 13 The agents behave as servlets

3 September INBOSA workshop 14 Security  Fine grain authorization/authentication mecanisms;  Confidentiality and Privacy;  Accountability.

3 September INBOSA workshop 15 Conclusion  Web server independence  Restricted execution environment  Agents behave as regular servlets  Dynamic architecture  Small runtime footprint
