Cisco Internet Streamer CDS Overview

With the Content Delivery System (CDS) software installed, the CDE functions as a Content Delivery
System Manager (CDSM), Service Engine (SE), or Service Router (SR). The CDSM provides a
graphical user interface (GUI) to manage registered Service Engines and Service Routers. The CDS
solution addresses the need to distribute and receive high-bandwidth, media-rich content across the
Internet without performance losses or content delivery delays.
CDS software offers the following content-based services:
• Content caching and hosting
• Proxy services
• Content replication
• Video streaming
To deploy Cisco SEs with Cisco CDS software within your existing network, your network must support
Cisco IOS software.
The CDE refers to the hardware that can run one or two Content Delivery Applications (CDAs). Each
CDE can be configured with a specific device mode. Each device mode defines the set of CDAs that can
run on the CDEs. As part of the CDE installation and initialization, you are asked to select a device
mode. The following device modes are supported:
• Content Delivery System Manager (CDSM)
• Service Engine (SE)
• Service Router (SR)
