SDN components transform the LAN

Full software-defined networking is elusive in the local area network, but SDN components can help create a LAN that is more flexible and programmable. Users are beginning to explore what SDN elements like centralized management of policies and roles and automated configuration can do to improve documentation, application integration, network monitoring and security.

In this month's cover story, we consider how "SDN-lite" components can change the LAN.

In addition to software driving LAN improvements, software is also furthering advancements in the cloud. In another feature, enterprise experts describe how they are moving toward 100% unified communications in the cloud by retooling IT's focus and building enterprise users' confidence in the technology.

Finally, in this month's Subnet Q&A, read about first responders in California who have found they are better able to fight wildfires and resolve medical emergencies with a stronger Wi-Fi network and greater communications capabilities.
