RADISYS SOLUTION BRIEF | Radisys M-CORD: The Open Platform for Emerging 5G Applications 4 www.radisys.com M-CORD Objectives and Differentiation As the global mobile industry matures and continues to develop the next-generation technologies needed to meet the staggering mobile data demands at lower costs, many of the objectives that drive the M-CORD roadmap and release plans, developed within industry forums such as ONF and 3GPP, are inline with Communications Service Providers' business goals. Key M-CORD Objectives: • Replace vertically integrated legacy hardware in cellular networks with the CORD platform • Utilize end to-end network slicing, based on SDN/NFV/Cloud principles (RAN, Core, fronthaul and backhaul) • Provide a platform for enabling and onboarding new localized edge services • Offer a platform with open source and disaggregated components for new use cases • Support the programmable observability and analytics framework of CORD M-CORD offers a new paradigm for mobile, cable and even fixed-line service providers to play a significant role in the evolution to 5G, due to its ability to provide services with reduced CapEx and OpEx and increased agility, and offer new services to end users. M-CORD allows service providers to offer Network-as-a-Service (NaaS) to other service providers, allows for offering differentiated services, and most importantly allows service providers to enable dynamic finer control of the network to suit IoT and other similar new types of services. The CORD community has proposed key objectives around programmable observability and analytics framework to enable the real time closed loop operation of the RAN, EPC and the CORD platform and reduce the extent of monitoring infrastructure by enabling dynamic monitoring and instantiation of probes as and when required.
