Connectivity
Currently there is a full 2000 mbps (2GiG-E connections)
supplying our Data Center. In OC fiber line terms that’s
close to 3- OC-12 lines and 1- OC-3 line.
The use of non-blocking gigabit devices throughout the
network ensures regional latency of a few milliseconds or
less, suitable for the most demanding delay-sensitive traffic.
Use of redundant fiber rings ensures network reliability
and availability.
The data center has connections to many different Internet
backbones including Level3, AT&T, Genuity, Time Warner
and Yipes. By connecting to multiple tier 1 backbones, the
data can be distributed through many sources. This architectural
design also means that the network connections are not dependent
upon an single Internet backbone. Thus when probems occur,
traffic rerouting is automatic, thereby ensuring the integrity
of the network and continued access for our high-speed servers.
This takes the term “multi-homing” to a whole
new level. Presently bandwidth utilization is 5% during
peak traffic times. Therefore, the network is very flexible.
If one of the backbone connections experiences problems,
the traffic can simply be rerouted 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 redistributed 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. Ether switches and high-end
Juniper routers anchor the local network. 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.
