CSCug89455 - Video detection using HTTP payload contents
Applicable Products: GGSN, HA, IPSG, P-GW, SAE-GW
Feature Changes
Video Detection using HTTP Payload
Readdressing to CAE is done only for HTTP video traffic. Non-video traffic will be sent to the origin server (until flow
is readdressed to CAE for the first video request). The mechanism for detection of HTTP video traffic is based on
inspection of HTTP payload for video signatures. Only Response payloads will be inspected and not request payloads.
MVG supports video types such as FLV, ISOM (mp4, 3gp, 3g2, qt, f4v, m4v, etc.), moov, wmv, MPEG2_TS, AVI, and
so on.

so on.
Limitations:
This mechanism may have some performance impact.
Only the first packet of the response video header will be inspected. If video header is not complete in the first
packet of the payload due to TCP fragmentation, then video detection may not happen by this mechanism.
Chunk encoded video responses, and compressed/encoded videos may not be detected by this mechanism.
Command Changes
http reply payload
This new command allows you to define rule expressions to enable video detection using HTTP payload content.
