Orange Business Services is working with several vendors to develop multivendor SD-WAN expertise and counting on MEF application programming interfaces and definitions for SD-WAN to enable a single portal for its SD-WAN offering, says Franck Morales, vice president of marketing of connectivity services for Orange Business Services. In addition, its SD-WAN service will be built on four other pillars: native cloud connectivity, best-of-breed security, global services and future-proof solution.
