Multiple UPS Systems are in place with generator backup.
What is “our” network architecture?
We at Lisfan Network have built one of the most reliable networks available in St. Louis. A network that is in our own Network Operations Center (NOC). A network that we own, operate and manage from end to end. A network built on only the finest hardware. A network that includes the following;
Lisfan has two separate major links into the internet backbone. Lisfan’s principle link is a FULL DS-3 (45 megabit/second) connection into AT&T. Our secondary link is yet another FULL DS-3 with access to UUNet and Level3. Additional connectivity into the St. Louis eXchange provides access to educational resources and other local St. Louis region networks without the need to criss-cross the country to the MAE’s. Lisfan also maintains a 45mbs PVC from our DS-3 ATM Frame into a third backbone – which may be turned up within minutes – giving Lisfan Network and it’s customers a total of 135mbs of fully redundant backbone access.
Our core router is a Cisco-7513 with dual processors and redundant power supplies that are fed by seperate power sources. In addition, two of each required card has been pre-installed in order to provide immediate backup in the unlikely event of a hardware failure. Furthermore, a second Cisco-7500 series router backs up the core router.
Separate and redundant connections through multiple access points is called multi-homing. Multi-homing allows internet traffic to be routed along the most effective paths. Besides providing faster access to commonly accessed data sources, our multi-homed strategy also provides redundant workarounds to ensure that your business connection and site are available to the entire internet community at all times, even if one of our links may be down.
A data center quality UPS (uninteruptible power supply) combined with a generator provides multi-phase conditioned on-line power protection for the entire NOC (network operations center).
