The future of WAN optimization: SD-WAN
Network managers today are less likely to be sweating over how traffic from traditional applications like SharePoint performs over the wide area network (WAN) compared to cloud apps that users access via the Internet.
This shift, along with enterprises' desire to eliminate or reduce the number of expensive MPLS links they use, is prompting WAN optimization vendors to pivot their strategies. Their new focus is software-defined WAN (SD-WAN), a concept that attempts to combine the benefits of WAN optimization and software-defined networking by virtualizing the WAN. The goal for companies using SD-WAN is to enable network managers to aggregate multiple Internet connections so that they function as a single virtual overlay that provides a level of performance and reliability on par with private WAN connectivity.
In this issue of Network Evolution, explore the promise of SD-WAN, why enterprises are interested in it and what it means for the future of WAN optimization.
Also in this issue, learn more about why collaboration and unified communications (UC) are being increasingly pushed out of desktop clients and into Web browsers. We dig into the pros and cons, and hear from enterprise IT pros who share their real-world experiences with browser-based UC.
Finally, cut through the hype and horror stories about security threats in the Internet of Things (IoT). We catch up with several enterprises that have deployed IoT and find out how they're using their networks as the first line of defense.

Enterprises want to drop costly MPLS links but hesitate to lose the control they provide. SD-WAN offers a solution, and WAN optimization brings it to life.
For so long, UC apps have been in a separate silo. Web-based collaboration tools like Cisco Spark and Unify Circuit bring UC to where users actually work.
Horror stories in the consumer market have cast a shadow over the Internet of Things. Are enterprise IoT deployments even more at risk?
In this Q&A, an IT pro at Penn Mutual shares how his dual strategy of user education and Layer 7 visibility helps prevent network breaches.
