Your customer would probably be gravely offended and unbelieving at the prospect that most major changes in digital computing connectivity involve a trade-off of some kind, but that doesn't render it any less accurate.
In this case, since the trade-off is between exposure to non-unicast traffic and level of interactive involvement with the address procural process, why not shrink the relevant timers? Would they notice the extra traffic? If they're not happy with either scenario, then both the issue & its resolution catapult way above the OSI layers that fall within the IS manufacturer's purview, usually leading to a rather ungraceful resolution. I've found that opponents of major redesigns will leverage the reality that many types of changes do NOT result in situations featuring only benefits and no drawbacks to fight or impede the cutover as vociferously as possible, forcing an appeal to the economic considerations that motivated the project in order to squelch the dissensiion. ----- Original Message ----- From: "Chuck's Long Road" To: Sent: 28 September 2002 1:28 pm Subject: Re: OT: Serves Me Right - DHCP problem [7:54402] > I see I should have made this one a "Friday Folly" :-> > > In a Big Flat Bridged Network, a mobile user unplugs the laptop at one > office, drives over to the next office, plugs back in, and no further action > is required.
