If you can't answer, dont bring up about technologies, protocols,
QoS, and CISCO products here. Just focus on buy/sell and make
money on CICSO.

First, I'd be happy to. My post that you are attempting to discredit I believe was intended as a helpful "tutorial" for someone other than yourself.

let say a FT1 of 64K link
connection to the Internet via a Satellite.

An FT1 of a 64K link? What is that? There is no such thing. Are you saying 64K?...via Satellite? You want real time over satellite with a 64K line - I don't think it's possible. The best you can do is perhaps 500ms...that's about all you can get - even with CBR over a single satellite hop. If you're using satellite for real-time traffic you're living in South America (with all due respect to my friends down there). Now of course you can certainly do some tricks to reduce jitter using jitter buffers etc..but latency issues can not be overcome.

Finally if your attempting to use OSPF to deliver QoS...Hee hee...good luck. MOSPF/OSPF are not a mechanisms built to deliver real-time traffic, rather they're mechanisms intended to calculate the best/shortest path through a routed network. There is no ability to determine traffic types and handle them differently depending on latency/jitter requirements. There is information available on the web re: OSPF/MOSPF- just look around. It might be helpful to you.

it's obvious that there will be no problem for delivering real-time
QoS over high-speed network. Anyone can build a faster ATM switch
to accomodate that. The question here is what you meant by "a mixed
switch/router environments will continue to drive the industry"?


Oh...if you'd like me to elaborate just let me know. ;0
