Cisco Content Delivery Engines Generation 2
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 platform for video delivery. The
Cisco CDS delivers an unprecedented level of scalability and reliability while giving service providers a
distinct service-velocity advantage in enabling the next generation of personalized entertainment and
interactive media. The Cisco CDS platform combines Cisco CDEs with Content Delivery Applications
(CDAs), software elements that provide ingest, storage, caching, personalization, streaming, and other
real-time, scalable, and resilient capabilities. Cisco CDEs and CDAs can be flexibly configured to support
a host of networked value-added services that service providers can rapidly deploy to attract and retain
subscribers.
Networked Cisco CDEs work together to form a scalable, flexible, and highly available system that enables service
providers to rapidly deploy high-value services such as video on demand (VoD), time-shift TV, network personal
video recording (nPVR), and targeted ad insertion.
Product Overview
Cisco Content Delivery Engines form the hardware foundation of the Cisco Content Delivery System platform, and
consist of a number of networked, multifunction server appliances that 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 Content
Delivery Applications are installed on it.
The 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
●
Cisco Visual Quality Experience (Cisco VQE): Error repair, statistics gathering, and channel change-time
acceleration
Table 1 provides a mapping between the Cisco CDAs and the various CDE models. To obtain detailed information
on all CDAs, please refer to the CDA product literature.
