Ciena’s Emulation Cloud™ is designed to help network operators exploit the potential of open APIs, which are a foundational element of Software-Defined Networking (SDN). Emulation Cloud provides a software integration environment users can rapidly develop, test, and integrate new applications with Ciena’s open APIs without investing in their own IT and network infrastructure. This paper features two case studies that demonstrate the tangible cost and efficiency benefits realized by using Emulation Cloud.
