Cogent owns one of the largest networks in the
industry, covering more than 22,500 route miles worldwide.
| Cogent
Communications, founded in August 1999, owns and operates
ones of the world's lowest-cost, highest-capacity IP networks.
Since its founding, the company has expanded rapidly to become
the largest Ethernet service provider in the United States according
to Ovum—in 2004 alone,
Cogent acquired nine companies. |
|
Cogent's total of 13 acquisitions has helped to expand the company's
network, which now serves over 90 metropolitan markets in North
America and Europe, and encompasses:
- 1,050 multi-tenant office buildings strategically located in
commercial business districts;
- 220 carrier-neutral Internet aggregation facilities, data centers
and single-tenant buildings;
- over 150 intracity networks consisting of over 9,000 fiber
miles and ranging in capacity from 16 to 160 Gigabits
- an 80 Gigabit (8 OC-192s) intercity network of more than 22,500
fiber route miles; and
- four leased high-capacity circuits providing a transatlantic
link between the North American and European portions of Cogent's
network.
The network itself can be broken down into three key elements:
INTERCITY NETWORK. A long haul
international backbone consisting of eight OC-192s (four OC-192s
in Europe) that links over 90 major cities, is Layer 3 protected,
and utilizes IP-over-WDM technology, making it the largest network
of its kind in the industry.
METROPOLITAN NETWORK. Within each
city, multiple DWDM and CWDM metropolitan rings with capacities
of between 16 and 160 gigabits, providing 5 Gbps of dedicated
capacity from the core router to each building node.
IN-BUILDING NETWORK. Cogent's network
extends directly into office buildings, colocation centers, and
data centers via Ethernet or OC-48 to reach its customer base.
Cogent equipment is placed in each building, and connects via
fiber or CAT-5 cable to each customer premise.
Cogent's network is built in a ring architecture, which provides
two diverse paths to every building. In the event that the fiber
is cut, the router detects the cut and redirects the traffic around
the ring away from the cut, restoring connectivity within one second.
The company's pricing can be extremely straightforward—Cogent
offers a flat rate fee of 100 Mbps for $1,000 per month. This price
has been in effect since Cogent opened its doors in 1999.
In addition to Internet service, Cogent offers Native Layer 2
Point-to-Point (transport) service in all its On-Net markets.
