QOS for voice and video

Hi All


When providing QOS for voice and video

should I put the RTP for video in the priority queue?


or should the rtp voice go into the priority and the video go into another queue with gaurenteed bandwidth?


can anyone give me a good example which also includes signalling, say over a 40Mb wan link

Is the video streaming or real-time?  If the former, a non-LLQ class usually is fine provided there sufficient (class) bandwidth to support it.

If real-time, ideally you want to treat like VoIP, i.e. LLQ/PQ.  However, if you have insufficient bandwidth, normally VoIP bearer gets LLQ/PQ.  If you have some additional bandwidth, and if the video's sound track can be treated separately from its video track, you next include the video voice in LLQ/PQ.

With real-time video, keep in mind it's often very bursty, so ideally you want to allow for peak burst rates, not average rates, to avoid queuing delays.
