[altq:1817] Re: Dynamic ALTQ Question

Hi Nicolas,

Thanks a lot for your reply. I need to change dynamically because
my needs changes dynamically. This means that Live video sources are 7
and archived video sources are 5. So I am not sure when my clients
want to watch video from which server.

an ideal situation is like this


Live Video Source-1 -------------------
---                                   |
                                      |
Archived video Source-1---------------
----                                  |
                                      |
Live video source-2------------------  ALTQ Box ------My LAN
---                                   |
                                      |
Archived Video source-2 --------------
---



Now any of these can be called for data at any time. So this is the reason
I want to configure dynamically based on IP address. I can bear delay but
no loss of packets.

I hope you can make sense out of it.
