Today’s IT teams must be able to respond quickly and flexibly to evolving business requirements. Forms of working and business processes are changing, fuelled by advancing digitisation and technological innovations. And this, in turn, affects business-network requirements.

Networks are integrating more and more systems communicating with one another via data connections. The associated explosion of data quickly pushes network capacity to its limits, shining the spotlight on IT availability and security as well as network infrastructure. Networks must also be able to respond quickly to threats posed by malware, DDoS attacks and cyber criminality. Unfortunately, implementing a perimeter firewall has become woefully inadequate.Network access controls and role-based policies, on the other hand, contribute greatly to protecting business networks against malware and unauthorised access from within the network. Today’s advanced networks are also able to detect data-flow anomalies, responding straight away by initiating countermeasures.
All of these reasons make it necessary for modern networks to be able to adapt highly to changing requirements. Security and Quality-of-Service rules must be easily and quickly configured and deployed enterprise-wide. Last but not least, automating administrative tasks lowers operating costs and boosts efficiency.
Employees expect to work with modern communication and collaboration tools. They also want the flexibility to access business services and data anytime, anywhere.A well-managed network infrastructure is essential for providing employees, visitors and customers with secure access, or for accommodating the use of smartphones, tablets and other mobile devices. In today’s digital era, smart networks also enable new business models. Analysis of website usage patterns, mobile engagement and marketing, digital production environments and smart cities are just some of the new strategies being tapped into.
Moreover, business-critical, added-value services such as IP phones and video conferencing—not to mention advanced communication platforms—rely on high-availability, secure infrastructures. It is these infrastructures that usher office environments into the future.
Innovative data-centre architectures have been developed to accommodate the new criteria businesses seek to fulfil through their network infrastructures. Such architectures are characterised by first-rate stability, performance and availability. In addition to enabling programmability, data-centre networks support extensive automation and serve as the backbone of hybrid and private clouds.
