Access "The programmable WAN: Applications are boss and networks bend"
This article is part of the October 2013 / Vol 4 / No.5 issue of Five trends changing the game for UC
Software-defined networking (SDN) is making the WAN the new black. That's because the avant-garde in networking is a virtual infrastructure that can be provisioned on demand and in response to the needs of rapidly moving virtual machines (VMs) and applications. SDN is beginning to make this possible in the new programmable WAN. The goal of the programmable WAN is to use an SDN controller essentially as a network hypervisor to automate the provisioning of virtualized WAN tunnels or network segments in support of VM migration, fluid applications and varying data flows. In most forms of SDN, the control plane is separated from the data plane and the intelligence and decision making is placed into a centralized controller. In the WAN, that controller sees the network end-to-end, and from the packet layer to the optical transport layer, explained Ashish Shah, director of product strategy and product line management at Vello Systems, an SDN upstart that provides the infrastructure for open, programmable networks. Applications play a central role in WAN ... Access >>>

Is IT operational efficiency sexy enough to entice investment?
by Rivka Gewirtz Little
Technologies like unified communications and SDN promise IT operational efficiency as a return on investment, but that can be difficult to measure.
Application visibility and control tools emerge for the wireless world
by Chuck Moozakis
A new generation of application visibility and control (AVC) tools allows network managers to peer into applications across their WLAN infrastructures and optimize how that traffic is delivered. These new AVC tools will help network managers deliver a wider range of critical applications to both personal and enterprise-issued devices.
