1 Distributed Real-time Systems of Future Dr Peter Parnes 011213

2 2/9 Dr. Peter Parnes, CDT More General Devices than Today Today, several different devices for different things. Phone, Calendar, Hand-held computer They should/will all merge into one useful device Different carriers

3 3/9 Dr. Peter Parnes, CDT Adaptive Applications Able to handle different bandwidths Between 10Kbps to 100Mbps Adapt immediately Must be error resilient Handle partial data Do re-transmissions on higher level Don’t transfer at bit-level but at application level

4 4/9 Dr. Peter Parnes, CDT Context Aware Certain applications should behave differently in different contexts Position-aware... ”Mentality”-aware... Is my calendar full with a long to-do list? Bandwidth availability aware...

5 5/9 Dr. Peter Parnes, CDT Network Centric Information should not be stored ONLY in your hand Synchronize constantly with other hosts ”Standard” applications should be available everywhere Phonebook, calendar, tasks, Borrow your friends device All you need is a digital key

8 8/9 Dr. Peter Parnes, CDT Research Reliable Multicast on Application Level (not bit-level) Congestion Control User Interfaces small devices and wearable computing Scalable media distribution Both up and down in quality Symmetric Context awareness Security & Privacy

9 9/9 Dr. Peter Parnes, CDT Discussion Questions and Discussion
