WAN Wrap-Up

The need for business agility has been the impetus of just about every big cultural and technical trend in IT over the last decade, from the spread of the DevOps movement to the growing interest in public and private cloud computing. Just as organizations are rethinking their data centers through this focus on agility, they are also looking to make their WANs more responsive, reliable and scalable for today’s most important applications.

Enter the software defined WAN. A solution like Talari’s Failsafe WAN, which continuously analyzes each path on the network and ensures the integrity of mission-critical VoIP and video traffic, is becoming essential to building an agile business, one with a network that can make smart real-time decisions based on company priorities. Let’s look at some recent highlights and news about the SD-WAN’s growing importance.

Companies face huge opportunity cost in delaying shift to software defined WANs
Enterprises spent more than $12 billion last year on private cloud infrastructure, but a good chunk of that sum may have been wasted due to slowness in simultaneously upgrading the network. ZK Research principal analyst Zeus Kerravala recently estimated that these organization took an average of four months to implement any change on their networks.

Moreover, he emphasized the importance of moving to hybrid and SD-WANs, with a smart mix of MPLS and broadband Internet to support cloud-based applications as well as mobile usage. The classic hub-and-spoke architecture is not ideal for today’s networking environments, since it depends on MPLS links that do not optimize the use of bandwidth and may lead to session drop on failover.

Kerravala also noted that he had seen much more interest in hybrid and SD-WAN in the last year than in the entire preceding decade. Some organizations are going so far as to ditch MPLS links altogether for more cost-effective yet still high-performing architectures.

The central role of the WAN in the rising telemedicine industry
Telemedicine is a rapidly growing industry that is addressing the widespread problem (mostly in the U.S.) of limited physical access to healthcare providers. The market could nearly double in size from 2014 levels by 2019, according to ReportsnReports.

The WAN will be essential to the growth of telemedicine. For starters, remotely consulting with patients and making diagnoses for them will require dependable voice and video applications such as VoIP and video conferencing. Providers will also be counting on the cloud to streamline costs and increase agility.

“The WAN will be essential to the growth of telemedicine.”

“Some applications may rely primarily on synchronous or asynchronous messaging to facilitate consultations; the more advanced will enable live video consultations, a must in some specialties,” explained Jude Chao for Enterprise Networking Planet. “And those live video consultations will demand a fast, stable, and secure WAN connection.”

Talari announces completion of first Open Networking User Group testing program
Founded in 2012, the Open Networking User Group promotes open networking infrastructure through its small, user-focused conferences. To this end, it also tests network overlays, network services virtualization and SD-WANs against the requirements set out by its ONUG Working Groups.

This May, it completed a three-month long testing process in conjunction with Ixia, marking the first time that commercial solutions in the aforementioned categories had been evaluated in relation to ONUG criteria. Talari met the ONUG’s requirements for SD-WAN with testing of its Adaptive Private Networking technology and Talari appliances T3010, T510 and Virtual Appliance T500.

During the tests, Talari’s solutions demonstrated the ability to direct traffic across a hybrid WAN according to application type and company policy. They also showed the capability of applying prioritization to specific applications during congestion caused by link failure.

Overall, the ONUG testing process has proven how Talari’s Failsafe WAN provides the adaptability needed for ensuring application performance, even during link failure. The test conditions mirrored what many hybrid WAN and Talari users already experience on daily basis to show how common issues like congestion can be overcome with the proper solutions.
