The Cisco cBR-8 router
offers the next generation CCAP platform supporting converged CMTS and EQAM
functionality. The redesigned video data model supports the creation of virtual
edge devices within the platform. This data model simplifies the provisioning
procedure and enables seamless migration to virtualized video service
management in the future.
The video provisioning
constructs of the new data model provide hardware abstraction and divides
services into virtual edge devices for easier provisioning at scale. It also
provides isolation between the service applications at the software layer. A
bind-operation connects these constructs to the physical resources.
The Video Services
Provisioning Model has the following elements:
Logical Edge Device
(LED)—a virtual edge device in the Cisco cBR-8 chassis that can be
provisioned for static or dynamic sessions.
Virtual Carrier Group
(VCG)—a collection of Virtual QAM Carriers (RF channels) provisioned on an
Virtual Edge Input
(VEI)—assigned either globally to all VCGs in the LED or optionally
assigned uniquely to an individual VCG.
Service Distribution Group
(SDG)—a collection of one or more RF ports that define the physical
slot/bay/port to be used in a video service.
Virtual and Physical Constructs
The VCGs are bound
to an SDG using a bind command (bind-vcg). This connects the virtual carriers
to the physical ports listed in the SDG. After binding, a path from the VEI is
mapped to the RF ports.
