Port? Protocol? Camera? File Type?

-

hi all,

i have read information windows media services on windows 2008 r2 still not point of implementing this. have basic questions, if answer - great.

  1. what protocol used? http or rtsp ? or choose? if choice, best?
  2. what should output file type camera or polycom?
  3. can live capture in london, , have data published france office well. users in france should stream local server(s)? mean, have put different urls sites/locations?
  4. any examples on bandwidth - 2000 users connecting streaming server in datacenter 128kbps connection each etc.....

the whole idea take live camera conference , have around 10k users across organization , globe access live. things multicast, windows media player 9, hardware not issue.

1) windows media player defaults using rtsp first, can fall http if necessary.  see blog on protocol rollover more info:  http://blogs.msdn.com/b/randomnumber/archive/2008/08/18/windows-media-player-protocol-rollover.aspx

2) if creating on demand clips should record in wmv format.  if live need connect machine running expression encoder directly camera.

3) yes.  1 option.  you're talking load balancing.  there number of solutions including dns round robin, hardware solutions, , application based solutions.

4) multicast best option if have large live event.  assuming network multicast enabled.  if have go unicast route you're talking lot of bandwidth.  if have 2000 users connecting via unicast @ 128 kbps 256 mbps of bandwidth.  more you'll need several servers distribute load around network.

i'd suggest reading deployment guide @ http://technet.microsoft.com/en-us/library/bb676138.aspx  give better idea of expect.
