One on One Internet's Network Operations
Center in Baltimore, Maryland is "OnNet" with Frontier
Global Center (FGC), which means that we have a direct fiber
optic connection between our Cisco 7200 router and theirs.
Being OnNet with a Tier-1 provider means that we don't link
to a backbone, we are actually on a backbone. We have no phone
circuit, and don't use a Telecom link to get to the Internet;
instead, we have an in-house connection directly to FGC's ATM
fiber node, located a few floors below our servers in the same
building.
This fiber optic line can handle the bandwidth
of a T3 or an OC3, and with FGC's Dense Wave Division Multiplexing
(DWDM) technology, it can handle several times the bandwidth
of an OC3.
We share the digital distribution architecture
of FGC, which is comprised of more than 25 high-speed private
peering connections to major Internet carriers such as MCI, Sprint,
UUNET, AT&T, AOL, Best, Erols, and others. FGC also has high-speed
links to 8 public exchanges including both MAE East and West
and several NAPS.

Website templates for quickly building websites and online stores Vooweb.com - Website Templates can offer specific website templates for Word Press, osCommerce, Magento, CubeCart, CRE Loaded and Prestashop We have a large investment in BGP (Border Gate Protocol)
technology, which allows the traffic to your site to travel more efficiently
by finding the best route for data to travel. On a typical server the
traffic always takes the same route from client to server. For them,
if there is a bad node, traffic does not get through at all. Because
we use BGP protocol, different and more efficient routes are taken between
client and server depending on traffic loads and broken nodes. This means
our servers automatically look for the fastest route available. Low Latency/High
Throughput Often providers operate their networks at three to four times
responsible capacity, and as a result the corresponding transfer times
reach over 300ms for each hop along the net. One on One Internet's network
daily average is 6.5% of its capacity, with mid-day peak spikes reaching
only 15.5% capacity. Our transfer times range from 15 to 80ms routinely.
At One on One Internet, we understand the importance
of speed, security, and reliable connectivity. We have invested heavily
in hardware and facilities that ensure that your site is up and running
on the web 24 hours a day, seven days a week.
GC, a Tier 1 provider whose 13,000-mile fiber optic
network and Dense Wave Division Multiplexing (DWDM) technology provide
an enormous 460 gigabytes per second (Gbps) of capacity worldwide,
has an Asynchronous Transfer Mode (ATM) fiber node.
Qwest comes into Baltimore with an OC-12 line and plans
to upgrade their connection to an OC-48 in the near future. Our Qwest
connection enables One on One Internet to offer additional redundancy
and better routes to Europe, Latin America and Asia. With our carriers,
our router has up to 150,000 possible routes to send each packet of traffic.
Genuity, a division of GTE, is our third Tier One Internet
backbone. Genuity provides excellent network performance as a result
of their high-speed peering arrangements with other Tier One Internet
backbone providers. The GTE global network delivers customers directly
onto the Internet via a high-speed connection to its private, super-capacity
backbone, including 17,000 miles of fiber and OC192 capacity. It is comprised
of more than 800 U.S. local access points and approximately 1,500 international
local access points in more than 150 countries.

One on One Internet uses intelligent end-user
routing software called Border Gateway Protocol (BGP), between
Qwest, GC and GTE, who use the same protocol. BGP identifies
which path is the most efficient for each data packet and then
routes the packet to its destination on the fastest path. This
increases the speed at which web pages sent from our NOC arrive
at their destination.
Studies have shown that the most common reason
for downtime is circuit failure on Tier 1 provider backbones,
the major data highways. To guard against this potential problem,
we have three Tier-1 providers. If one experiences problems,
we can route traffic down the other one. Furthermore, because
we are OnNet with GlobalCenter, Qwest and GTE, we share their
digital distribution architecture, which includes private peering
network connections to major Internet carriers such as MCI, Sprint,
UUNET, EUNET, AT&T, AOL, Best, Erols, @Home, IBM Advantis
and others. These private peering arrangements allow One on One
Internet to exchange packets of data with every major backbone
carrier in a one-to-one environment quickly and efficiently.

In addition, GC has high-speed links to eight public exchanges
including both MAE East and West and several NAPS. Through these public
exchanges, customers have the ability to reach their site, no matter
from where they are coming on the Internet.
Too often providers operate their networks at three to
four times responsible capacity. As a result, their corresponding transfer
times reach over 300ms. One on One Internet.com's network daily average
is 27% of its capacity, with midday peak spikes reaching only 33% capacity.
One on One Internet.com guarantees clients will be carried off our network
in less than 80ms over a five minute average at any time of day or night.
Industry analysis reveals that 70% of downtime over ten
hours with any ISP is caused by telephone circuit failure. Since our
NOC is in the same building as Global Center, Qwest and GTE, circuit
failure is virtually eliminated because there is no phone circuit between
us and our providers. Instead, there is a direct connection between our
Cisco 7500 routers and theirs.
One on One Internet's providers also have peering connections
with other major Tier 1 providers, which allows traffic to be switched
to alternate backbones should the need arise.
To guard against local power failures, One on One Internet
has two industrial-grade, three phase Liebert UPS systems. These act
as back-up batteries, maintaining uninterrupted power in case of surges
or power outages. With these backup systems in place, we can keep our
network up and running indefinitely without relying on external power.
One on One Internet's NOC has two Liebert ten ton industrial
air conditioners, which condition our computer rooms and operations center.
Our computer room is kept at an optimal temperature of 65 degrees Fahrenheit.
One on One Internet's web servers are custom-built industrial
machines designed for a 24/7 web serving environment. All One on One
Internet servers are equipped with dual redundant 450-watt power supplies,
hot swap Seagate Barracuda/Cheetah drives and force-filtered cooling
systems. In addition, our NOC is equipped with an inventory of identically
configured, burned-in standby servers.
All of One on One Internet's custom web servers
are equipped with a positive pressure filtered-air system. Four large
fans pull filtered air into each server's protective case and the components
within are cooled by fans which circulate this purified air. This constant
introduction of clean air into the case creates a positive pressure
environment ensuring dust and particles remain outside of the server.
The drives and drive bays of all One on One Internet.com
servers are constructed from high-grade aluminum, and rest in shock mounted
drive cages, which adds to the durability of the hardware. One on One
Internet's drives proudly feature the lowest failure rate in the industry.
Each server employs dual-redundant hot swap power supplies.
If a power supply were to fail, the server would continue running with
power from the alternate supply. Meanwhile, alarms would alert a technician,
who would quickly restore redundancy. In the meantime, servers and client
sites would experience no downtime.
We keep spare servers on-line of all CPU configurations.
If a server were to experience a hardware failure, we would turn a
key, grab the handle on the drive, pull it out, and insert it into
an identical standby CPU. We would then reboot the second machine and
the server would be up and running again in a matter of minutes.
