Verizon Adopts Cisco's iWAN SD-WAN Suite
Organizations are looking for a more efficient and cost-effective way to move traffic than in a traditional WAN setup, where traffic is passed back and forth from remote sites into central data centers via MPLS or other technologies. SD-WAN enables remote offices to connect directly to the Internet via high-speed broadband, and offers a fast and secure way for mobile workers to connect into the network. "SD-WAN is really beginning to see a surge in adoption," Jason Rolleston, senior director of product management for Cisco's Connected Mobile Experience unit, told eWEEK. Analysts at IHS Infonetics are seeing the same thing. They said in May that of 150 businesses in North America that responded to a survey, 45 percent expect to increase their investments in SD-WAN over the next two years. While in the data center there is demand for raw speed supported by SDN and virtualized workloads, "outside the data center, SDN-led transformation is taking hold in the WAN optimization market," Cliff Grossner, research director for data center, cloud and SDN at IHS, said in a statement. "There's a shift from optimizing application traffic flows over a single point-to-point WAN link to automated and dynamic load balancing of application traffic over multiple link types—MPLS, broadband, Internet, cellular, etc." The number of competitors in the space also is growing, including Talari Networks, Glue Networks, Silver Peak, Viptela, Ipanema Technologies, VeloCloud and others. Cisco's Rolleston late last month published what he is calling an "SD-WAN Bill of Rights," a listing of 10 points that businesses can use as a guide for creating a comprehensive strategy and determining which SD-WAN offerings suit them best.
