of Impact “Nearly 40% of all end-customers will have service provided by … CORD by mid-2021” Roz Roseboro Heavy Reading “70% of operators worldwide are planning to deploy CORD” Michael Howard IHS Markit
• Represents a huge opportunity • CORD has emerged as a compelling platform for the new network edge • Leverages disaggregation, open source and white boxes • Puts SDN, NFV and cloud technologies into a compelling solution • Many service providers experimenting and have plans for trials and deployment • CORD has a growing community of 60+ companies representing various stakeholders • CORD has been demonstrated to support all three domains of use • Residential (R-CORD) • Mobile (M-CORD) • Enterprise (E-CORD)
