Lots of this has to do with your constituents. If you're a dial-only provider, you can afford not to care (much) about latency. You ALWAYS care about packet loss, but latency can go to the dogs and your customers won't know much about it. If you serve DS1 customers, its a different ballgame. Now you HAVE TO provide good network infrastructure, or people consider your plant to "suck". Then again, my background and engineering efforts have been geared towards the Fortune-50 marketplace and OLTP environments where ANY packet loss or significant hysteresis in the transport times is considered unacceptable. We build 'em "a bit different" around here. -- -- Karl Denninger ([email protected])| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly / All Lines K56Flex/DOV | NEW!
