Cisco CDE Features and Benefits
Designed to increase flexibility, Cisco Content Delivery Engines can be grouped into arrays that operate as a
single logical system. Service providers can easily expand capacity by attaching additional Cisco CDEs to the
array, thereby achieving almost unlimited video storage and streaming capacity. The Cisco Videoscape
Distribution Suite employs a hierarchical storage design that allows service providers to maintain huge content
libraries while actually simplifying content storage management.
Cisco CDEs adapt automatically to unpredictable and rapidly changing traffic patterns. The platform preserves
video programming in a common, shared storage array that is instantly accessible for streaming anywhere in the
network. Cisco Intelligent Caching technology automates the distribution of video content between Cisco CDEs by
responding dynamically to actual viewer demand and popularity trends. This adaptive content distribution model
helps ensure that the content that is most popular at any point in time at each network node is always available in
local storage, significantly reducing the bandwidth burden on the network backbone. This flexible architecture and
the effectively unlimited scalability of content libraries make the Cisco VDS an attractive solution for efficiently and
cost-effectively delivering "long-tail" content, network-based time-shifted programming, and user-generated
content. This feature helps increase network scalability while reducing capital expenditures (CapEx) and operating
expenses (OpEx).
Cisco CDEs are also designed for fault-tolerant operation. They can share states and work together as a single
logical pool of resources that can be dynamically reallocated across the network's available hardware capacity in
response to service requests. In the event of hardware failure, the Cisco VDS immediately delegates the functions
being performed by the failed device to other Cisco CDEs in the network. Furthermore, the system automatically
discovers the addition or removal of a Cisco CDE and reconfigures itself without service disruption or manual
intervention, vastly simplifying maintenance and upgrade operations.
A network populated with Cisco CDEs becomes a platform upon which new services and applications can be
layered over time and deployed much more quickly than was possible in the past. The platform unleashes the
power of IP networking technology by creating a video infrastructure capable of delivering nonstop availability,
high scalability, and low total cost of ownership. Taking advantage of the extensible architecture of the Cisco VDS,
operators can deploy on-demand video services today with the knowledge that they can expand their services to
support real-time applications and multiple forms of interactive media content delivered to many types of devices.
