Re: Bandwidth Upgrade

That depends on the network configuration though.  If you have redundant
links and one link is at 65% and the other is at 35% or more you won't be
able to get through a circuit flap or outage without dropping packets.

Ideally, when our 95th-percentile hits 65% utilization, we begin the
pricing and planning process and its up on peoples radar. Once the
95th-percentile hits 80-85% we start planning the maintenance and execute
the upgrades. I say ideally, because in a perfect world this would happen
100% of the time.

We try to upgrade when the 95th is at 80-85%, because the 95th-percentiles
is based off 5-min polls, so I am sure traffic is spiking higher at peak
times.

Greetings,
               My team is in the process of putting some documentation
together to justify a bandwidth upgrade. I am asking if you would be
willing to reply back to me, with how you decide that it is time to
upgrade
your bandwidth. On-line or off-line reply's will be acceptable.

Thank You
