Virtualizing the Cable Access Network

Transformation through virtualization

Begin the next phase of your network’s transformation by virtualizing your headends with cloud-native technology. Introduce the dynamic scale and agility your network needs to deliver the services your customers want.

Going cloud native

Navigate your way towards virtualizing your headend by going cloud native. Discover your path for migrating headend functions to the cloud and turning dedicated hardware into scalable software.

The economics of cloud CMTS

Benefits of virtualizing your headend with Cisco’s Cloud Native Broadband Router(cnBR)

NETWORK SCALE

Subscribers per headend i This figure is the estimated number of DOCSIS subscribers per Data Center, Headend or Hub area. The total number of subscribers is used to calculate the total RPD’s per service area.

NoError

Subscribers per RPD i This figure is the estimated number of subscribers per Remote PHY device (RPD). The subscribers per RPD is also used to calculate the total RPD’s per service area.

NoError

Average DOCSIS devices per subscriber i This figure is the estimated number of DOCSIS devices within a subscribers home. The devices per home includes Cable Modems (CM’s) as well as DOCSIS Set-top Gateways (DSG’s). This figure is used to calculate the total number of DOCSIS devices supported per Cloud Native server.

NoError

Downstream Bandwidth per RPD (Gbps) i Downstream Bandwidth per RPD. The upper limit maximum is set to 9.0 Gbps and lower limit is set to 0.3 Gbps.

Gbps
NoError

Upstream Bandwidth per RPD (Gbps) i Upstream Bandwidth per RPD. The upper limit maximum is set to 6 Gbps and lower limit is set to 0.05 Gbps.

Gbps
NoError

Over subscription factor (n:1) i This figure is the ratio that the Data Plane bandwidth (DP) per server is over-subscribed relative to the provisioned bandwidth per RPD. An oversubscription factor of 1.0 (1:1 ratio) equates to no over-subscription.
