Architecture
The Exchange is Ethernet-based and currently operates 3 chassis-based switches, two Cisco 7600 series and a Cisco 7010 series (Operationalized April 2011). Peers connect to the Layer 2 fabric, and use IPv4 & IPv6 addresses provided by TorIX to connect with each other, utilizing the BGP routing protocol. Port speeds of 1000LX (GigabitEthernet) and 10GE are available, including in bonded configurations. Single-mode fiber is required, and peers can connect from anywhere in the building via the meet-me-room.
If and when the Exchange expands beyond its current physical location, it will likely choose an architecture model which permits geographically connected Exchange participants to peer with each other. For technical reasons, this model is not always chosen in such circumstances, however TorIX has the resources to accomplish that successfully.

Famous quotes containing the word architecture:
“All architecture is great architecture after sunset; perhaps architecture is really a nocturnal art, like the art of fireworks.”
—Gilbert Keith Chesterton (1874–1936)
“For it is not metres, but a metre-making argument, that makes a poem,—a thought so passionate and alive, that, like the spirit of a plant or an animal, it has an architecture of its own, and adorns nature with a new thing.”
—Ralph Waldo Emerson (1803–1882)
“It seems a fantastic paradox, but it is nevertheless a most important truth, that no architecture can be truly noble which is not imperfect.”
—John Ruskin (1819–1900)
