A modern city consists of interconnected sub-systems such as energy, transport, water, buildings etc. In the past, these sub-systems have been individually modelled as part of Smart City deployments without much consideration to their interdependency and interaction. Moreover, solutions proposed for such models have been proprietary both in terms of vendor and technology.  

Zeeta Networks proposes a new integrated approach where a Smart City is modelled as a network of sub-networks (note: sub-network is defined as a group of interconnected devices such as computers, telecom equipment, wireless access points, sensors and actuators, etc.) where its design, construction and operation follows Software Defined Networking (SDN) and Network Virtualisation (NV) principles. The core SDN/NV technologies used in Zeetta’s Smart City solutions have been developed by the University of Bristol, England over 5 years as part of European, UK Government and Industry funded research.

The cornerstone of the proposed solution is the Smart City Network Operating System (NetOS™) which provides a centralised view and control of all the underlying physical sub-networks and offers the ability to construct virtual “network slices” (i.e. separate logically-isolated sub-networks) which can be individually monitored, controlled and used to deploy a wide range of secure B2B or B2C services such as Internet of Things (IoT) deployments, Traffic Control, Water Management, wireless bi-directional communication to moving vehicles, UHD video distribution etc.

By adopting a SDN/NV architecture, it is possible to create an efficient open-source development platform that allows any enterprise, regardless its size, to break into the market of Smart-City Application and Network Service Development that -so far- has been dominated by proprietary platforms and large vendors. This will allow, for example, any small or medium enterprise to utilise the Smart City infrastructure to develop its own Smart City Application and test it directly onto the same infrastructure which will be used later for its commercial deployment.

Zeetta’s NetOS software solution has been deployed in a real operating environment tackling real city problems as part of the “Bristol is Open” (www.bristolisopen.com) Smart City testbed,  the first worldwide Smart City deployment based on Software Defined Networking and Network Virtualization principles.
