Virtualized Cable Access With Cisco Cloud Native Broadband Router (cnBR)

Bookmark
34 Launches
Solution Overview

Cisco's Cloud Native Broadband Router (cnBR) is a virtualized Cable Modem Termination System (vCMTS)/virtualized Converged Cable Access Platform (vCCAP), allowing operators ease of scale, lowered CAPEX and OPEX, and increased bandwidth capabilities. Utilizing Intel® Xeon® Scalable processors, cnBR enables cable operators to transform their network to meet increasing bandwidth demands, reduced CAPEX, and OPEX.  

The Cisco Cloud Native Broadband Router solution comprises a few key components. The first component, the cnBR Core, provides the DOCSIS processing, DOCSIS management, and telemetry functions and acts similarly to a traditional CMTS/CCAP system. The second component is Cisco Operations Hub (OPSHUB), which monitors and manages the cnBR Core cluster. The Service Provider (SP) router forwards traffic between the system components. The Remote Phy Device (RPD) converts the incoming digital optical signal to an analog RF output for last-mile connectivity to subscribers. 

Goals & Objectives

This lab introduces users to the Cisco Operations Hub component of cnBR and how to navigate its dashboards, management and APIs to monitor performance, view configurations and retrieve information while providing hands-on experience with a vCMTS system.
