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. 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 the 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.
