11 Simulation and Emulation Using ns-3 19/Jun/2014 Workshop on Mobile Cloud Networking 11

12 ns-3: An Open Source Network Simulator ns-3 is a discrete-event network simulator targeted for research and educational use 19/Jun/2014 Workshop on Mobile Cloud Networking 12

13 ns-3 Models 19/Jun/2014 Workshop on Mobile Cloud Networking 13

14 ns-3 Emulation Capabilities ns-3 designed for integration into testbed and virtual machine environments 19/Jun/2014 Workshop on Mobile Cloud Networking 14

15 Direct Code Execution (DCE) in ns-3 DCE Module for ns-3 Executes in ns-3 existing implementations without source code changes Tested Applications CCNx, Quagga, iperf, ping/ping6, ip Mobilt IPv6 daemon (umip) Linux kernel (from to 3.7 versions) HTTP server (thttpd) Torrent 19/Jun/2014 Workshop on Mobile Cloud Networking 15

16 From Simulation to Real Networks with ns-3 ns-3 building block real building block ns-3 system ns-3 system ns-3 system Simulated Emulation+DCE Real 19/Jun/2014 Workshop on Mobile Cloud Networking 16

17 Development of Building Blocks ns-3 building block real building block spec Model development Prototyping From specifications Direct Code Execution Fast prototyping Efficient code ns-3 system ns-3 system ns-3 system ns-3 system ( rbridge case ) 19/Jun/2014 Workshop on Mobile Cloud Networking 17

18 FINE: Future Internet experimentation via ns-3 Network Emulation ns-3 Consortium aims to explore emulation at large Extend testbeds with built-in emulation capabilities Integrated management/control of real+emulated resources 19/Jun/2014 Workshop on Mobile Cloud Networking 18

19 Mobile Cloud Networking and ns-3 emulation 19/Jun/2014 Workshop on Mobile Cloud Networking 19

20 Mobile Cloud Networking ( From Deliverable 2.2 of MCN project ) 19/Jun/2014 Workshop on Mobile Cloud Networking 20

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 21

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 22

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 19/Jun/2014 Workshop on Mobile Cloud Networking 23
