SD-WAN 2018: The Interoperability Challenge The 3rd SD-WAN Summit will be held 26/28 September 2018 in Paris CDG. The Summit will confirm its position as the leading event for stakeholders in this new technology. Interoperability, Security, Scalability It will be interesting to see next September how much SD-WAN is reshaping the overall telecom industry and wether or not it is impacting the globalization of business services and service providers’ footprints. Indeed, before reaching this level, the SD-WAN offer must acquire a wider scope of features in terms of security and scalability. Above all, the different offers have to become interoperable in order to definitively win over operators and very large enterprises. The 3rd SD-WAN Summit will be an occasion to see just to what extend the different SD-WAN stakeholders have become aware of these imperatives.
