( From Deliverable 2.2 of MCN project )

19/Jun/2014 Workshop on Mobile Cloud Networking 21

MCN Challenges

• Moving resources to the cloud implies – New techniques for managing resources

– New functionality for provisioning /monitoring network resources

• New protocols and distributed systems

have to be developed and validated

• Non-functional properties must be preserved/characterized – System performance, QoS, QoE

– Reliability, availability, resiliency, redundancy

19/Jun/2014 Workshop on Mobile Cloud Networking 22

ns-3 may help

• ns-3 – addresses the evaluation of non-functional properties – demands the description of statistically-relevant behaviours/use cases

• ns-3 is focused in IP and wireless/mobile networks

• ns-3 supports the simulation of large scale systems – distributed simulation is possible

• ns-3 enables the combination of simulated and real systems – Emulation, Direct Code Execution

• ns-3 models may be reused to develop prototypes – step-by-step, in short times

• ns-3 contributes to maintaining the testbed always operational – while moving from all-simulated to all-real

19/Jun/2014 Workshop on Mobile Cloud Networking 23

Conclusions

• Simulation is alive! – still has a key role to play in mobile networking

• ns-3 has high quality, maintained, verifiable code

• ns-3 enables – performance evaluation and main use case validation

– combination of models with real building blocks

– fast prototopying

– short validation times
