Cisco VDS Internet Streamer Overview
The Cisco Videoscape Distribution Suite Internet Streamer (VDS-IS) is a distributed network of CDEs
running Content Delivery Applications (CDAs) that collaborate with each other to deliver multiformat
content to a variety of client devices. The client devices supported are personal computers and
Wi-Fi-enabled mobile devices.
The VDS-IS supports a variety of functions to accelerate the distribution of content within the content
delivery network. The VDS-IS offers an end-to-end solution for service providers to ingest and stream
entertainment-grade content to subscribers.
The VDS-IS functionality can be separated into four areas:
•
Ingest
•
Distribution
•
Delivery
•
Management
Each CDE in the VDS-IS contributes to one or more of these functions as determined by the CDAs
running on it.
