The document discusses a case study of MWH Global implementing a software-defined WAN with Cisco and Glue Networks. MWH Global had challenges with provisioning remote sites, operational complexity, and high WAN costs. Using Cisco's software-defined WAN technology and Glue Network's orchestration platform, MWH Global saw benefits like 10-15 times more bandwidth, significant cost savings, and faster deployment of remote sites. The solution provided flexibility, resiliency and automation to simplify their network while reducing costs.
