Cisco Systems 100/200/300/400 Manual De Usuario

This chapter provides an overview of the Content Delivery Engines (CDEs) and describes the hardware 
and software features. This chapter contains the following sections:

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)
