Great reference and I've learned a tremendous amount from this list. I learned that I have been mis-using the term Leaky Bucket. I now understand that what Jason described to the list is Token Bucket (I was totally wet in my earlier reply calling it Leaky Bucket).
Radios that implement bw management vary considerably in sophistication of their bw management algorithms. I'm really impressed with the Alvarion bw management. Canopy has bw management built-in as well, but it seems less sophisticated. I'm also impressed with what I've learned Linux advanced bw management can do at the head-end if your radios don't. Given radios can be bridged or not, bw management in the in-radio implementations seem better ... because I don't see how head-end bw management can distinguish between bw to multiple destinations behind the same customer radio if the radios are bridged. Even if the radios are not bridged, then I'd see in-radio bw management as 'still' better because bw limited at the customer radio doesn't chew up inbound rf capacity, while in head-end bw management the rf inbound capacity gets burned whether the traffic is ultimately limited or not. Anyways, I'm getting a great deal from the discussion, and would love to hear if other radios have built-in bw management and what method is use for comparison (any Trango users who could possibly comment?).

Starting at chapter 9, it goes into some detail on how some of the the algorithms available work and how to implement them. http://lartc.org http://lartc.org/howto/lartc.qdisc.html > thanks again, > Rich -Ryan -- InvisiMax Ryan Langseth Systems Administrator [EMAIL PROTECTED] work: (218) 745-6030 -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/ -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
