Connectivity:
Currently there is a full 2000 mbps (2GiG-E connections) supplying
our Data Center. In OC fiber line terms thats 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 Qwest, AT&T, Level3, 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.
