Our servers are Intel Pentium III class, running at the clock speed of 733 MHz, with 512MB of SDRAM and an 18 GB SCSI hard drive.
The Network
Operations Center (NOC) where our servers reside is located in Baltimore,
Maryland, and is OnNet with Frontier GlobalCenter (FGC) and Qwest Communications
through two separate bandwidth-on-demand connections which enter Downtown
Baltimore just a few floors below the NOC.
FGC, 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 ATM fiber node located just a few
floors below the NOC.
Qwest comes into Baltimore with an OC-48 line. They also have an ATM fiber node 14
floors below the NOC. Qwest comes into Baltimore at the same location with an
OC-48 line. Our Qwest connection enables us to
offer additional redundancy and better routes to Europe, Latin America, and
Asia. With these two carriers, our router will have up to 150,000 possible
routes to send each packet of traffic.
Furthermore, because of these unique connections, we no longer need to link
to the Internet though an OC3 or T3 Telecom circuit. Instead, independent cables
run inside the building directly from the NOC to both the Global Center point of
presence and the Qwest point of presence. These lines can handle the bandwidth
of a T3 or an OC3, and with DWDM they can handle several times the bandwidth of
an OC3.
Network Redundancy
We use intelligent end-user routing software called Border Gateway Protocol
(BGP), between Qwest and FGC, who use it as well. BGP can identify which path is
the most efficient for each data packet, and then route 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 second most common reason for downtime is circuit
failure on the Tier 1 backbone, the major data highway. To guard against this
potential problem, we have two Tier-1 providers. If one has problems, we can
route traffic down the other one. Furthermore, because we are OnNet with
Frontier GlobalCenter and Qwest, 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 us to
exchange packets of data with every major backbone carrier in a one-to-one
environment quickly and efficiently.
In addition, FGC has high-speed links to 8 public exchanges including both
MAE East and West and several NAPS. Through these many public exchanges,
customers have the ability to reach their site wherever they are coming from on
the Internet. Thus we have the best of both worlds: a network that is both
efficient and wide reaching.
Network Reliability
Industry analysis reveals that 70 percent of downtime over 10 hours with any
ISP is caused by telephone circuit failure. Since our NOC is in the same
building as Frontier Global Center, circuit failure is virtually eliminated
because there is no phone circuit between us and FGC. Instead, there is a direct
connection between our Cisco 7200 router and theirs.
The second most common reason for downtime is circuit failure on the Tier 1
backbone. FGC, themselves a backbone, also have peer connections with other
major Tier 1 providers, which allows traffic to be switched to other backbones
quickly in the event of a crisis.
How reliable is this? Yahoo is another fine company who connects directly
using only FGC. If you can reach Yahoo, you can reach our network. FGC's
groundbreaking 460 Gbps network runs BGP to 25 other major carriers through
private peering arrangements, providing the fastest, most efficient and most
reliable network available today.
Raw Performance equals Low Latency/High Throughput
You can't drive an engine as hard as it will go and expect consistent high
performance. But often providers operate their networks at three to four times
responsible capacity, and as a result their corresponding transfer times reach
over 300ms. Our main network daily average is 6.5 percent of its capacity, with
midday peak spikes reaching only 15.5 percent capacity.
