Overview
The Cisco Content Delivery System (CDS) is a distributed network of Content Delivery Engines (CDEs)
running Content Delivery Applications (CDAs) that collaborate with each other to deliver multi-format
content to a variety of client devices. The client devices supported in Releases 2.0–2.3 are personal
computers and Wi-Fi-enabled mobile devices, such as personal digital assistants (PDAs).
The CDS supports a variety of mechanisms to accelerate the distribution of content within the content
delivery network. The CDS offers an end-to-end solution for service providers to ingest and stream
entertainment-grade content to subscribers.
The CDS functionality can be separated into four areas:
• Ingest
• Distribution
• Delivery
• Management
Each CDE in the CDS contributes to one or more of these functions as determined by the CDAs running
on it. Table 1-1 describes the relationship between the CDA names and the Internet Streaming Content
Delivery System Manager (CDSM) device names.
