2 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

3 Traditional CMTS/HFC vs. vcmts TODAY HUB QAM CMTS RF combining splitting Analog Optics Analog Fiber OPTICAL NODE Analog Optics RF RF / Coax STB CM vcmts Centralized PHY HUB vcmts PHY Analog Optics Analog Fiber OPTICAL NODE Analog Optics RF RF / Coax STB CM HUB vcmts Agg IP Switch R-PHY NODE IP RF / Coax STB PHY RF CM vcmts Remote PHY HUB vcmts Agg IP Switch R-PHY NODE IP RF / Coax STB PHY RF CM 3

4 The Promise of Virtualization Virtualization separates software from hardware Quickness and agility to increase business efficiencies and productivity Scalability Elastic deployment Sustainable capacity management Many drivers for software-based solutions Continued CPU performance growth Open-source software Insatiable consumption of data Growing number of consumer devices Enable change at a pace which exceeds demand in the most effective manner 4

5 vcmts Enablers CableLabs Remote PHY Standard Separating the PHY from the CMTS Core Standards-based approach Commercial- Off-The-Shelf (COTS) Intel x86 Servers Today s performance is great Annual performance increases 5

6 40 Years of Microprocessor Trend Data Source: 6

7 CMTS Deconstructed Aggregation and Forwarding All embedded in CMTS/CCAP platforms vcmts Software Remote PHY Hardware 7

8 vcmts in a Remote PHY Architecture vcmts Core Internet IP Cable Modem Edge Router IP Switch IP IP Remote PHY Node RF Set-Top Box Video Video Core Out-of-Band Core 8

9 Hardware-based CMTS Challenges Long development cycles Limited capacity Limited scalability Limited flexibility High operational expenses 9

10 vcmts Opportunities Shorter development cycles Operational benefits Increased scalability Increased flexibility Improved Total Cost of Ownership (TCO) 10

11 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: 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

12 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: 12

13 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

14 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

15 Case Study Remote PHY Space and Power Savings # of Racks Legacy Over 90% savings 5 vcmts vcmts delivers dramatically reduced TCO whether deployed as part of a distributed or a centralized architecture. 15

16 Conclusion Remote PHY and Virtualization Benefits Quickness and agility to increase business efficiencies and productivity Scalability Elastic deployment Sustainable capacity management 16
