Tata Spins a Tale of 2 SD-WANs

SD-WAN services are becoming pretty commonplace, and that competition is driving some service providers to try to differentiate, going beyond just offering a managed-services version of one SD-WAN vendor's gear.

Tata Communications Ltd. is one such differentiator, and its special sauce is internally developed software that allows an enterprise to automatically prioritize traffic that goes from a headquarters or hub sites out to remote sites. That can be important because, while software-defined WAN services allow broadband Internet connections to handle business traffic with the same security as more expensive MPLS links, they can't always prevent congestion.

Typically, remote sites don't have the bandwidth of larger hubs, Hon Kit Lam, vice president of Global IP and Managed Network Services, tells Light Reading in an interview. As more business applications move into the cloud, the likelihood of those links becoming congested grows as well. So, in addition to offering one version of its IZO SD-WAN based on Versa Networks technology, Tata created a second version, called IZO SD-WAN Prime, that includes its own software for doing dynamic congestion management.

That software builds on an Anuta Networks Inc. orchestrator and, based on pre-set policies, prioritizes critical traffic to avoid packet loss or delay, Lam explains.

Essilor, a producer of ophthalmic optics, is using IZO SD-WAN to expand its business into markets such as Africa and Asia Pacific, where making use of available bandwidth is critical, says Marc Tanguy, director of IT Technology Services in Asia-Pacific, Middle-East, Russia and Africa, in an email exchange. He says the service has allowed Essilor to connect new locations very quickly, making business expansion much easier.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
