2. Problem
to solve
IoT traffic management in a Smart City
divided into smart multi-tenant spaces
over a shared, SDN-based metro network
and cloud infrastructure.

3. Solution
Novel network application for the
automated initiation and provisioning of
end-to-end communication channels
through the SDN infrastructure from
“internet things” to dedicated services
deployed in the cloud via containers for
data storage, visualization and analysis.

4. Recipients of
the solution
Administrators of inteligent spaces (Smart
City, Smart Building) equipped with
multiple IoT devices, who would like to
optimize IoT traffic management by the
orchestration of common network and
containerized cloud resources.

5. Advantages
orchestration of shared network and
containerized cloud resources from one
common network application
new IoT devices recognized automaticly
by network application - just plug IoT
gateway to SDN switch
all owners of IoT devices can get easy
access to IoT data through dedicated
Thingspeak portal

6. Multi-party
partnerships
Solution prepared in close collaboration
between research and commercial
organizations.

7. Use case:
Poznan
Smart
City

8. Goals of the
demonstration
 to present new network application running on top of the SDN for
dynamic creation of the end-to-end communication channel from
„things” to the cloud over SDN infrastructure
 to show extensions provided by NoviFlow using the standard
OpenFlow experimenter capabilities:
 Matching on specific bytes in the UDP Payload*
 Setting the value of specific bytes in the UDP Payload*
* for traffic from IoT Gateway to OpenFlow 1.3 switch
 to show how STC can be used to generate multi device IoT test
traffic

9. Proof-of-concept,
but ready to use
now!
 Orchestration of cloud and network resources
 Traffic management between IoT gateways and cloud services
 TCP/UDP traffic analysis (IoT devices recognition, categorization
and policies)
 On demand creation of LXC light containers
 AutomaticThingspeak service deplyment over containers for real-
time data collection, storage, viualization and analysis
 SDN network provisionig
 Utilization of OF experimental extenssions: deep packet
inspection and metadata injection
 Based on Ryu SDN controller (OpenFlow 1.3 +)
