What is a Converged Network System?
The Converged Network System (CNS), which is also referred to as the Common Network System or the Landlord Integration Network, is a single IT managed network infrastructure and is critical to the success of a smart building.
Typically, a CNS consists of core high-performance network switches, creating a series of highly secure Virtual Local Area Networks (VLAN) which allow secure network data ports to be assigned and managed so that traffic flows are optimised. Next-Generation Firewalls (NGFW) provide protection against Cybersecurity threats, and the use of Wi-Fi provides the required robust connectivity coverage beyond the wired VLAN.
The CNS allows the integration between Information Technology (IT), Operational Technology (OT) and Internet of Things (IoT) assets and building systems. By connecting these together, the CNS enables different systems within a building to interact with each other securely and effectively and provides a single data pool to analyse building performance.
Why does a building need a CNS?
Traditionally, one of the biggest issues in buildings has been a lack of interoperability between systems and infrastructure, with consequent silos of data preventing a true understanding of the building’s performance. Where a building has disparate networks supporting business functions, it will not be able to reach its full potential as a ‘smart building’ even if using Internet Protocol to exchange control information.
The CNS however is an intelligent and secure multiservice Internet Protocol (IP) platform that is designed to support the BMS and all other IP-enabled applications and solutions.
Systems talk to Systems
A well-designed deployed and managed CNS is critical to unlocking the full functionality of the BMS. Most large Commercial Real Estate developments contain a wide range of technology systems. The core systems or OT (Operational Technology) such as Heating, Ventilation, Air Conditioning, Lighting, Lifts, CCTV etc typically integrate with a Building Management System.
By layering the OT and IOT systems and connecting the BMS over the CNS all are interconnected, facilitating automation and delivers a single view on ‘whole building data’.
What are the key benefits of having a CNS?
Optimum Availability and Reliability:
Delivering a faster, more powerful network, even for large and complex networks.
Flexibility:
Through an integrated connectivity approach, leveraged across multiple technologies, including Wi-Fi and Power over Ethernet (PoE), the building infrastructure can be aligned to specific Smart Building goals and adapted as changes need to be made.
Flexible Configuration:
Using PoE technology in the design delivers specific smart building goals in a cost-effective, convenient and secure way to provide electric power to the building infrastructure.
Increased Security:
Swift threat identification and mitigation through integrated management of multiple devices and systems counters against the expanding range of IT, OT and IoT devices that present a new set of potential vulnerabilities to the network.
Minimise silos:
Any large building will have multiple ‘IP Partners’ such as HVAC, Lighting, CCTV providers etc. Deploying a single IT managed network infrastructure avoids the danger of silos and optimises building performance.
Data:
By connecting the IT, with the OT and IoT, a single pool of data enables a view of an entire estate in real time and allows data driven decisions to be made to achieve operational and sustainability goals.
