Customers connect to 4 Cisco 6509 routers
These routers have multiple
connections to our backbone routers. Backbone routers are
Junipers with multiple connections to our backbone OCn's.
The backbone is a Tier 1
backbone. Here is a link to the network map:
Domestic Comunications Map
The data center has
connections to many different Internet backbones including
Level 3, Williams, Global Crossing, YIPES, and XO.
By connecting to multiple
backbones, the data can be distributed through many sources.
This architectural design also means that the network
connections are not dependent upon any single Internet
backbone. Thus when problems occur, traffic rerouting is
automatic, thereby ensuring the integrity of the network and
continued access for our high-speed dedicated server clients.
This takes the term "multi-homing" to a whole new
level.
Presently bandwidth
utilization is 25% during peak traffic times. Therefore, the
network is very flexible. If one of the backbone connections
experiences problems, the traffic can simply be re-routed over
other paths, thereby ensuring that users receive fast access
times to sites hosted on our network.
In addition, the network runs
Border Gate Protocol (BGP4). BGP is used at a provider with
more than one access point to the Internet. It helps create a
truly redundant network. In fact, in an ideal situation, a
lease line failure should result in the BGP routing session to
close on the bad leased line and the router on a working
circuit should then begin to accept the additional traffic.
In other words, traffic from a
down circuit is re-distributed across other circuits, thereby
maintaining network integrity. Providers that are multi-homed
and correctly setup can actually be more reliable than a
single backbone provider because they have multiple paths to
multiple providers.
Internal Connectivity
A provider's local area
network is not often enough being seen as a point of latency.
The two main sources of latency for a full-time Internet
connection are the user's local area network and the Internet
provider's local area network. The local network is anchored
by Cisco 5500 Series ether switches and high-end Cisco routers
(like a Cisco 7513). This top-of-the-line network hardware
ensures that data requests get to their destination and back
out of the network as fast as possible. We use ether switches
instead of hubs because of their speed and their security
capabilities. Whereas only one computer plugged into a hub can
talk at one time, all the machines connected to a switch can
talk at the same time. This means more data can travel through
a switch and each server acts as its own node on the network.
Furthermore, since each server is its own node on the network,
it is difficult for hackers to trace data packets with
sensitive information (i.e. passwords) to a particular server.
Servers on the network do not
share a single path (T3). Instead, the servers are connected
into a high-speed ethernet switch. This switch is connected to
the core router at the data center. From the core router, data
is sent back to the end user across the fastest available
path. Whereas statically routing traffic over one path creates
a single point of failure, this distributed architecture
ensures that users can access data extremely quickly and have
multiple paths both into and out of our network.
