VPN configuration

[Jeffery Eric Contr 95 CS/SCBA]

If you go with a service provider like Savvis or UUNet or Qwest then you
will get an SLA for a VPN solution.  It may actually make sense for the 130
stores to get set up with a service provider so the company doesn't have to
manage the technology or worry about loss of employees or latency problems.

Chad is correct about the SLA and latency issues if you set up and run your
own solution.  We had issues with latency with one project so we went with a
dedicated T-1.  As the engineer I thought it was a bad, and costly solution;
however, that's why management makes the big bucks.

Jeanne,

Keep in mind that when you use an Internet VPN you can get no SLA to
guarantee uptime or packet delivery. So the question becomes, what do you
do when the Internet can't get the packets from the store to the date
center...

Since you'll have the circuit costs anyway you may not realize any $$$
benefit. Normally the cost savings with a VPN come from 1. Already
having/needing Internet access and 2. not having to seperate circuits/PVCs
for each location.

Not saying it won't work or save money, just that you need to be very clear
on your design criteria.


later...
