4. E 3 – ICT SUMMIT 2008 (10-12.06.08 – Stockholm) Slide 4 Autonomic Decision Making and Protocol Reconfiguration 1. A mobile device connects to a WLAN network using the information provided by the CPC controller 1 2. The user terminal locates a software error. 3. The software download manager, which is implemented with UDT is launched and initiates the downloading of the required software from the software repository that resides on the server side. 4. During this process, UDT is reconfigured. The latter is triggered by ADM upon realizing that the congestion control algorithm employed exhibits high RTT (threshold based policy evaluation). 5. As soon as the software package is downloaded, it is installed and the terminal runs smoothly. 6. Load is injected in the network. This has a direct consequence the triggering of a handover from the WLAN_1 network to WLAN_2 7. Terminal leaves coverage of CPC controller 1. Evaluates information provided by CPC controller 2 and connects to the WLAN_3
