Citrix Exec Explains Why Company is Uniquely Positioned for SD-WAN

By Paula Bernier January 05, 2016

This year should see the mass-market adoption of SD-WAN, a technology that meets the needs of today’s applications by providing large and reliable bandwidth. That was the message Chalan Aras, vice president and general manager of Citrix Systems, conveyed to us during a video interview at the recent TMC Editors Days in Santa Clara.

Wide area networks are becoming overwhelmed by traffic from software-as-a-service, Skype for Business, video, and VoIP applications, Aras said, and companies are responding by leveraging SD-WAN technology to meet that challenge. As discussed in the January/February issue of INTERNET TELEPHONY magazine, SD-WAN can aggregate various existing services such as DSL, high-speed cable, LTE, or MPLS and leverage software to create dynamic, high performance connections that provide lower costs and more flexibility than such popular business options as MPLS.

Citrix has a unique slant on all this, Aras said, given it has offerings and expertise both on the enterprise application front and in terms of Layer 4 through 7 networking products. He added that Citrix also is a player in the data center, where SDN transformation is already occurring. Citrix has a partnership on this front with Cisco and is working on OpenStack data center SDN orchestration, he added. All that said, Citrix can deliver what Aras described as an end-to-end, top-to-bottom architecture on the software-defined networking front.

SD-WAN has attracted a wide array of players and investments. Among those companies offering solutions under the SD-WAN banner are Cisco, Citrix, CloudGenix, FatPipe Networks, Glue Networks, Ipanema technologies, Nuage Networks, Ocedo, Riverbed, Silver Peak, Talari, VeloCloud, Versa Networks, and Viptela. Various sources indicate the SD-WAN space will reach $3.2 billion by 2018, $12.1 billion by 2019, and $7.5 billion by 2020.

As more businesses become interested in SD-WAN, so too are communications services providers, which want to provide these organizations with managed services based on the new technology. For example, Verizon in September became the first service provider to offer SD-WAN services based on Cisco’s IWAN solution.
