[SBE] Some IP Network questions

[Edwin Bukont]

For both the video and audio folks, questions.
 
1.  A friend, who is usually knowledgeable, made the statement that CNN generates many IP streams, reliably, for public consumption and that my concerns about network infrastructure  (Physical and Layers 1,2 and maybe 3) are overblown.  He claims that the technology has come so far that as long as you buy Cisco, HP, Juniper and focus on proper configuration (Layers 4-7), you can reliably do what you want.  He claims that network issues rarely are at the lower levels and mostly now occur as a function of poor config and management, not poor infrastructure.    My comment to him was that how you handle IP / IPTV for post-production streams is a completely different animal than how you handle IP connectivity concerns inside the plant related to bi-directional workflow for production.   I would tend to think that the integrity of the lower levels matters more for production than for distribution.
 
 So I am curious, what is CNN doing and how does their use of IP technology, complexity and network reliability concerns differ between production and distribution?  Is CNN (as my Cisco buddy claims) more concerned now with distribution rather than production because so much production now is ingested from citizen journalism?  I don't believe that the brick and mortar concerns of TV plants have really dimished that far, yet.
 
2.  Anyone tried use of 802.1(Qav et al) enabled switches yet in AOIP or IPTV plants.  Such switches do exist already.  Are there broadcast production devices encorporating these standards?  Anyone have experience at how well these switches handle L3 QoS for packets not bearing AVB?
 
3.  Anyone using a wireless packet sniffer?  If so, what, besides Fluke, are folks using?
 
Thanks
