Software Defined Networking
Static network architecture no longer cuts it in the world of the transformed datacenter. And this is where SDN comes in – to enable the on-demand initialisation, control and management of your network.
What is a Software Defined Network?
At the core of Arista’s platform is the Extensible Operating System (EOS™), a ground-breaking network operating system with single-image consistency across hardware platforms, and modern core architecture enabling in-service upgrades and application extensibility.
The most adaptable and dynamic operating system the networking industry has ever seen, with a single binary software image across the Arista switching family. EOS has a base set of commands, easily recognisable to users of the Cisco command line, and a full Redhat Linux core; both are fully accessible via command line and a programming API. This allows an Arista networked datacenter to automatically react to the movements of virtual servers, manage data flows and react to the ever-changing virtual world.
Through Cisco ACI, customers are reducing application deployment times from weeks to minutes. It also dramatically improves IT alignment with business objectives and policy requirements.
ACI provides a network that is deployed, monitored, and managed in a way that benefits different teams in the IT organisation including SDN Network, Cloud and DevOps, and Security. It supports rapid application change by reducing complexity with a common policy framework that can automate provisioning and resource management.
Nuage Networks take a bigger, more holistic approach to SDN. They redefine how both carrier and enterprise networks are built and this enables you to incorporate, operate, and provision datacenter cloud services as an integral part of your network services, rather than as an add-on to the network you already have.
Fulfilling the promise of SDN, Nuage are the only cloud networking solution that is truly open, flexible and designed to prevent vendor lock-in.

Networking, in particular, Software Defined Networking (SDN), is a key technology pillar in the delivery of the Software Defined Data Centre (SDDC). Network Virtualisation is redefining the delivery of complex network architectures, allowing them to be delivered in a fraction of the time.
VMWare NSX is leading the way in SDN through its automated provisioning of network and security virtualisation; bringing to traditional networking and security what virtualisation brought to the server computing industry. Network Automation removes the operational barrier the network has become, enabling IT to respond at the rate the business demands, increasing the speed of innovation and reducing time-to-market.
