5G is Different! 5G is about Applications at the Edge •  Yes, Higher speed & capacities, but also •  Things, sensors, actuators, computing at the edge •  Lower latency •  Heterogeneity •  Hugh scale •  Adaptability, flexibility, programmability •  Virtualization

Multitier cloud computing for E2E applications •  Situational awareness •  Sensing, Intelligence, Open Interfaces •  Essential for Smart City applications

What are SAVI and CVST? •  Smart  Applica,ons  on  Virtual  Infrastructures  

– NSERC  Strategic  Research  Network  –  “Canada’s  GENI”  – Partnership  of  industry,  academia,  research,  and  educaAon  networks  – Research  and  Testbed  on  Applica,on  Pla;orms  – Supports  research  of  100  graduate  /  postgraduate  students,  70  interns  – Applica,on  pla;orm  converging  cloud  compu,ng,  SDN,  SDR

SAVI’s View of Future Clouds • MulA-­‐Tiered  Cloud:  Core,  Smart  Edges,  Access  

Multitier Cloud supports applications •  Core Datacenter: massive data centers •  Smart Edge: Agile data centers residing closer to end users

contains heterogeneous resources & virtualizes access •  vCPE/Sensors: virtual Customer Premises Edge (vCPE)

resources support Internet of Things •  Application Platform: orchestrates E2E applications on

virtualized Software-Defined-Infrastructure (SDI) leveraging situational awareness and intelligence

SAVI Testbed: Smart Edge •  Smaller  scale  datacentres  close  to  end-­‐users  

•  For  services  requiring  low-­‐latency,  local  processing,  caching  •  Virtualizing  the  access  networks  

•  Virtualiza,on  of  heterogeneous  resources  •  e.g.  GPUs,  FPGAs,  Access  Points,  Sensors,  etc.  

• OpenBTS,  virtualized  WIFI,  virtualized  IDS/IPS  

SAVI vCPE (SvCPE) • Close Proximity: Host applications serve a small number

of users in very close proximity • Virtualized: Provide virtualized resources to support

different applications • Continuous Operation: continue functioning

independently in the event of network disruptions

Monitoring CO2

• Sensor nodes: consists of a carbon dioxide sensor and radio module

• Relay nodes: responsible for forwarding any received packet toward the destination

• Control Room: destination of sensor data and data aggregation point

Sensor Deployment on SAVI vCPE • Connect the destination node of the wireless sensor

network to the vCPE machine • Connected to monitoring and analytics manager, called

MonArch • Run the control room software and the MonArch data

collection Agent in the vCPE
