3847.0. "Limiting switch bandwidth on a per system basis?" by STRWRS::KOCH_P (It never hurts to ask...) Fri Sep 06 1996 18:35

    
    Has there ever been any consideration for our switch products to limit
    bandwidth for systems which are attached to them? I'm asking this from
    the perspective of an ISP who wants to match their WAN connection speed
    to the host it is connected to.

I don't understand the question. You want to rate limit
particular MAC adresses? As opposed to the switch port?

The part I'm having trouble with is 
"match their WAN connection speed to the host it is connected to"

3847.2<--- re:-1 wants to throttle specific nodes.....NETCAD::BATTERSBYWed Sep 11 1996 10:4811
    Mike, it sounds like a customer wants to be able to throttle the 
    traffic to/from specific nodes that are attached to a particular
    port. This can't be done currently....although *if* there was 
    enough of a business justification, such a feature could probably
    be done. Notwithstanding the business justification, from a practical
    standpoint, it would make more sense to provide those "noisy" nodes
    with their own dedicated bandwidth path that routes its traffic 
    through a dedicated subnet portal, so it wouldn't impinge on the
    other traffic in the rest of the customers LAN/WAN.

    Geez, Bob, I didn't realize you could mind read more than 10 miles
    out... ;)
    
    Yes, the customer would like the ability to throttle a system based on
    MAC address. However, to do this we might have to throw away packets on
    a shared LAN. If we had the system connected to a dedicated switch
    port, it might be "simpler" to throttle at this point by doing
    something as "simple" as holding carrier high. 
    
    I only have 1 ISP requesting this feature, but it seems like this is a
    generic kind of request that most ISPs would need. More research will
    be required to come up with a business justification.

    Yes 10 miles is about my limit. :-) Actually didn't you feel anything 
    when when I did a "virtual" mind-meld earlier today? :-)

    PS: It would appear that you spend a significant amount of time
    thinking about vacations in far-away places. But don't we all. :-)
