Network Infrastructure
Ivision Data Centers are connected to the Internet by redundant OC-12 circuits with
advanced capacity monitoring and planning able to scale to OC-192 capacity. For added
reliability and redundancy, our data centers are served by two different Central Offices
and have dual-path, dual-entry fiber facilities. These circuits terminate on dual Cisco
routers to ensure complete redundancy and maximum uptime. The entire system is designed so
that that there is no single point of failure. The Ivision network is designed to provide
the reliability, performance and scalability to maintain your mission-critical Internet
operations giving you the freedom and peace of mind to focus on your core business.

Connectivity
The servers your website is hosted on connect to the Internet through multiple redundant
connections provided by some of the largest backbone providers in the world - UUNET,
Sprint, Global Frontier and Applied Theory - ensuring data delivery to the end user in the
fastest, most efficient manner possible. OLM guarantees a 99.5% uptime by utilizing
redundant connections and data centers in both Sanjose and Los Angeles.
Routing
Our networks utilizes Border Gate Protocol (BGP4). BGP4 protocol is the standard that
allows for routing of packets of information sent out from the OLM Network, thus creating
a truly redundant network by routing traffic over the most efficient route possible. Due
to our redundant entirely switched Cisco powered network, data is automatically redirected
through another route in the event of a router failure. Should one of our backbone
providers fail, packets are automatically redirected through another one.
Bandwidth
We installed top-of-the-line Cisco Systems 7000 series backbone grade routers on the core
layer and Layer 3 switching on the distribution layer providing superior segmentation and
increased bandwidth across the backbone. Each server is connected to its own switched
100Mbps port reducing congestion. This configuration provides maximum uptime in the event
one of our providers faces an outage. Bandwidth utilization is continuously monitored,
allowing us to accommodate even the largest bandwidth surges.
It is a misconception that the amounts of bandwidth (size
of the pipes that carry the data) differentiate web hosting companies. But in reality it
is not the size of the pipe that matters, it is the utilization levels. We have multiple
redundant connections which allow us to guarantee customers a maximum of 60 per cent
capacity utilization at peak times and an average of 40 per cent utilization across our
network.
Monitoring
In addition to our multi-homed connections, our company performs 24/7 network monitoring
through both of our Network Operations Centers (NOCs) located in the US. Our NOCs monitor
the HTTP port, and conduct Ping tests every 5 minutes to determine if the servers are
active. In the event that a port is unreachable, an email is sent to every member of our
technical staff. Additionally, the NOCs provide our engineers with real-time status,
notification and forecasting of network events. Both of our data centers are monitored
24/7 by highly qualified network engineers and administrators.
