Managing Complexity with SDN Orchestration
Service & Content Providers’ Perspective of Smart Cities - How to enrich citizen
experience using a pervasive urban SDN connectivity environment

Introduction: Smart cities & IoT
Smart city Monitors critical infrastructures, optimizes resources, plans maintenance, offers services to citizens
and users.
50 billion devices expected to connect to the Internet by 2020 [Cisco, 2013]
Complexity management of monitoring, real-time data evaluation, …
Enhance/Automate decision-making?
Key elements:
Sensors/actuators (monitoring functionality, large amount of data flows)
Network (dynamic, large bandwidth)
Cloud (centralized approach) / Fog (distributed approach – end-user proximity)
Key requirements:
More agile IoT to accommodate the increased amount of transmitted data along with the expansion of connected devices
Flexible/elastic, dynamically adapting and large bandwidth network to connect sensors-to-cloud, cloud-to-cloud and multiple
end-users
High-capacity, fast processing, low latency to ensure quality of service and quality of experience

Take-away message 1:
Underlying Infrastructure to be complex & heterogeneous
To support new advanced city services and satisfactory user experience, the
underlying communications infrastructure needs to evolve, grow and adapt,
resulting in heterogeneous technologies (both at the data and control plane).
5G and beyond networks: 4G / 5G / mmWave /…
Net & Functions Virtualization, Fog & Cloud computing (local/remote processing)…
This network complexity needs to be managed

Take-away message 2:
Programmable optical technologies still much relevant
The optical technology still well positioned in view of latency / jitter and bandwidth
requirements Core of the infrastructure to support heterogeneous services.
Growth at the Data Center (Optical Interconnects) and Software Defined Optical
Transmission Flexible data plane supporting elastic, dynamic and reconfigurable
optical networks with scalable, power/cost efficient, and reliable technologies.

Take-away message 3:
Integration of SDN in a “CityOS” environment
A “SmartCityOS” platform can no longer rely on quasi-static network provisioning and will benefit from
network visibility & control and SDN principles. The re-configurability of the underlying networks
needs to be part of the “ToolBox” and “SystemCalls”
Unpredictability of traffic (bandwidth a scarce resource with latency requirements), dynamic management of services
Network Evolution for Smart City Services:
Infrastructure From a model of vertical (separated) networks for services to a convergent network model of
supporting diverse services and the implementation of new ones
Control SDN principles -- IoT Gateways (GW) and other network elements becoming SDN-enabled in order
to reduce operational and maintenance expenditures of the network.

Take-away message 4:
The need to orchestrate heterogeneity
It is not reasonable to assume a single “God” SDN controller controlling such
complexity, and we will need to manage vendor islands and segmentation
Scalable solutions will need to rely on abstraction, virtualization and orchestration
of cloud / network services

Take-away message 5:
The need for Open and Standard Interfaces - also for Nets!
An SDN/CityOS platform should relying on open and standard Data and Information Models,
Protocols and Interfaces, ultimately offering open access to collected data to public and third
parties. Enable applications that are developed to exploit the information "generated by
the city" and the layer of sensors deployed across the city.
cityprotocol.org -- seeks to define a common systems view for cities of any size or type, and then embraces or develops
protocols that will help innovators create – and modern cities deploy – cross-sectorial solutions that can connect and/or break
city silos.

applications, Facilitate others to reuse the tools and products.
