Enterprise workloads are all about scale these days. Even without big data, the internet of things and increasing mobile traffic, IT infrastructure is being pushed to the limit just dealing with normal production environments and ecommerce. This is why the cloud has emerged as a lifesaver for many organizations. By simply spinning up new resources on third-party infrastructure where and when they need it, organizations can more closely match their consumption with data requirements at any given moment ...

For many years, network engineers had a dream. Their vision was that one day a network's operations and management would be driven by its applications. Today, with software-defined networking (SDN), that dream is finally becoming reality. ADVA Optical Networking recently played a key role in a major European multi-layer multi-vendor SDN field trial that was proof of this. The demonstration highlighted some of the key achievements of the past few months. As well as use cases like traffic optimization and multi-layer re-routing following cable breaks, the most significant breakthrough was the utilization of an SDN architecture in real-world production networks. Juniper Networks and ADVA Optical Networking had already demonstrated packet optical multi-layer coordination at SDN OpenFlow World Congress in Düsseldorf, Germany in October 2015. In that showcase ...
