Features and Functionality
The following features and functions are supported on the Mobile Video Gateway:
Deep Packet Inspection
The Mobile Video Gateway performs DPI (Deep Packet Inspection) of HTTP traffic to identify video vs. non-video
traffic based on configured Active Charging Service rule definitions. An Active Charging Service is a component of the
Enhanced Charging Services on the Cisco ASR 5000.

While SPI (Shallow Packet Inspection) examines IP headers (Layer 3) and UDP and TCP headers (Layer 4) for an
Active Charging Service, DPI on the Mobile Video Gateway examines URI information (Layer 7) for HTTP message
information to identify video vs. non-video content based on configured rules. The following information is used for
DPI:

CAE Video Re-addressing
Important:
In 12.3 and 14.0 releases, the CAE video re-addressing feature is not fully qualified and is not
supported for field deployment. It is available for lab demo/lab trial only.
The Mobile Video Gateway can re-address HTTP video requests intended for video content Origin Servers (OS) toward
the Cisco CAE for retrieval of optimized video content. The Cisco CAE is an optional component of the Cisco Mobile
Videoscape. It functions in a video server cluster to bring additional optimization capabilities to the Mobile Videoscape.
