Here’s SDxCentral’s gathering of the week’s news bits around software-defined networking (SDN), network functions virtualization (NFV), and related topics.
This week's roundup features issues with Microsoft Azure; SDN products from Calient, ECI, and Extreme Networks; and a survey revealing service providers' doubts about SDN.
If there is a technology moving as quickly as SDN, it has to be photonics. SDN coupled with optical switching at Layer 1 allows the physical network to be reconfigured on demand to support changing traffic patterns and application demands.
Check out our Weekly Roundup for Friday, May 9, for news on EMC’s plans for hyper-converged infrastructure, HP’s $1 billion open cloud investment, and a surprising departure from Cisco’s unit for Internet of Things.
A very new startup with a CEO out of Facebook is providing the control plane for an architecture that could help data centers make use of all-optical switches — for handling elephant flows, for instance.
Optical switch vendor Calient Technologies raised $27 million toward its new life as a data-center player and a software-defined networking (SDN) asset.
The marriage of SDN with photonics to dynamically provide optical bypass, wavelength mapping for maximal throughput promises agility and performance.
