What is Remote PHY? Virtualization of the Core Asaf Matatyaou VP, Solutions and Product Management, Cable Edge
Traditional Deployment Challenges Traditional CMTS/HFC equipment does not sustainably address growing demands in bandwidth or services Data and video continues to grow exponentially Driving unsustainable power, space and cooling demands 2

Hardware-based CMTS Challenges Long development cycles Limited capacity Limited scalability Limited flexibility High operational expenses 9
vcmts Opportunities Shorter development cycles Operational benefits Increased scalability Increased flexibility Improved Total Cost of Ownership (TCO) 10
Containers and Docker Containers Virtual Machines Packages code and dependencies together Multiple containers can run on the same machine Share the OS kernel with other containers Docker is a set of tools to package and deploy containers, which can specify container constraints and access permissions Source: https://www.docker.com/what-container Abstraction of physical hardware turning one server into many servers. Each VM includes a full copy of an operating system Hypervisor allows multiple VMs to run on a single machine. 11
Kubernetes Kubernetes automates the distribution and scheduling of application containers across a cluster in a more efficient way. A Kubernetes cluster consists of two types of resources: The Master coordinates the cluster Nodes are the workers that run applications Source: https://kubernetes.io/docs/tutorials/kubernetes-basics/cluster-intro/ 12
vcmts Telemetry Telemetry Category Legacy vcmts Service Monitoring Labor Intensive SW analytics Service Event Storage Limited to local storage Cloud storage option Monitoring Data Periodic samples (i.e. every 15 minutes) Constant stream of data Tools Mix of custom & common Advanced Open Source Tools CLI, SNMP, & IPDR Supported Supported 13
Migration to vcmts vcmts co-exists with existing hardware-based systems Deliver immediate power and space savings Capacity headroom for many years to come vcmts architectures support legacy services MPEG video delivery (Video Core) Out-of-band (OOB) signaling systems for MPEG video delivery (OOB Core) vcmts feeds all data, voice and video services over IP, as legacy services diminish 14
