Cisco Content Delivery Engines – Generation 1
The Cisco
®
Content Delivery Engines (CDEs) are a family of carrier-class appliances that
power the Cisco Content Delivery System (CDS), an innovative, network-based, modular
video-delivery platform. The Cisco CDS delivers an unprecedented level of scalability and
reliability, while giving service providers a unique service-velocity advantage in enabling
the next generation of personalized entertainment and interactive media. The Cisco CDS
platform combines CDEs with Content Delivery Applications (CDAs), software elements
that provide real-time, scalable, and resilient capabilities such as ingest, storage, caching,
personalization, and streaming. Cisco CDEs and CDAs can be flexibly configured to
support a host of networked value-added services that telcos, cable operators, and other
service providers can rapidly deploy in order to attract and retain subscribers.
Networked Cisco CDEs work together to form a scalable, flexible, and highly available system that
enables telcos, cable operators, and other service providers to rapidly deploy a variety of high-
value services, such as video on demand (VoD), time-shift TV, network personal video recording
(nPVR), and targeted ad insertion.
Product Overview
Cisco CDEs form the hardware foundation of the Cisco CDS platform, which consists of a number
of networked, multifunction server appliances which can be centrally managed as a single “virtual”
server. Each Cisco CDE within the virtual server performs one or more functions depending on
which of the CDAs are installed on it.
Cisco CDAs can be grouped into the following service types:
●
TV streaming: Content delivery to TV sets through cable or IPTV set-top boxes
●
Internet streaming: Content delivery to IP devices connected to the Internet
●
Visual quality experience: Error repair, statistics gathering, and channel-change-time
acceleration
