[OPLINTECH] Bandwidth issues.

“Also, in response to Travis's anecdote, I'd like to remind everyone that in
the coming cold winter months, please try and always have at least a small
amount of traffic on your connections to prevent the lines from freezing.”

 

Is that really true???????

    Its actually not all that different than what the libraries would be
running into with a swamped receive utilization from patron traffic. Even
though you're looking to do a primarily transmit operation, the devices
still talk back and forth, so if your receive utilization is maxed, the
response from the server on the other end gets delayed, which slows the
whole operation. 

    The main thing we're doing with QoS at our core isn't targeted at doing
things like limiting MySpace traffic to only 50% of the line, its making
sure that when someone does something like requests a page from your web
server, the small request gets through quickly so the server can send out
its large response on the underutilized transmit bandwidth.

    Also, in response to Travis's anecdote, I'd like to remind everyone that
in the coming cold winter months, please try and always have at least a
small amount of traffic on your connections to prevent the lines from
freezing.

In my previous incarnation we ran into a similar issue but in reverse.  We
had more data coming IN than our T-1 cared for.  It was slowing down
important out-bound traffic such as payroll (accounting servers were located
in some remote portion of Borneo I think).  We implemented a band-aid
solution at the time.  We purchased a router capable of using 2 T-1 lines
and "balanced" some of our load over them.  Basically we reserved T-1a for
sales and accounting traffic and T-1b for "web" traffic.  We did use a few
cable modems for certain applications.  The place a cable modem was a good
idea (and proved reliable) was for incoming traffic.  Since most home
broadband configurations are heavy on download "speeds" and minimal in the
upload department, cable modems were ideal for traffic cams and such.

The ultimate solution came when Buckeye TeleSystems started offering
Metropolitan Ethernet.  Then, we hooked up a big ol' 10MB Ethernet
connection.  The cable modems are still in place for the most part, because
they seem to be doing the job that they were asked to do.
