An Internet Exchange (IX) or Internet Exchange Point (IXP) provides a means for network providers, Internet service providers (ISP) and content providers to connect locally to exchange data more efficiently. Internet Exchange users take advantage of faster, higher performing, lower latency routing and can also enjoy lower costs by reducing traditional Internet usage through a third party.

1GbE and 10GbE ports are free to participants. Involta hosts TUSIX in its purpose-built data center in Tucson, Arizona, and charges a monthly fee of $125 for single-mode fiber cross-connects with a one-time install fee of $125 for cross connects to TUSIX.

A cross connect is a physical data cable, usually copper or single-mode fiber, between one tenant’s equipment in their colocation space and another tenant at the data center. TUSIX only accepts single-mode fiber type cross connections.

Peering is the IP traffic exchanged between participants on the IX. Participants use Border Gateway Protocol (BGP) to peer with the IX route servers or bilaterally peer directly with another participant. Once BGP peering is established, participants can exchange routes of their public IP ranges.

TUSIX participants can peer with IX route servers or bilaterally peer directly with another participant. Once BGP peering is established, participants can exchange routes of their public IP ranges.

Anyone with a valid Autonomous System Number (ASN) from ARIN can connect to TUSIX.

Ask your Internet Service Provider if they are active on TUSIX. If they are not currently, ask them to join! You can also ask your provider about securing an ASN and public IP space.

TUSIX will issue IPv4 and IPv6 transit for connecting to the exchange. Contact ARIN to get IP space for your organization.

You can become a participant of TUSIX by filling out the TUSIX Participant Application Form.

TUSIX is operated by Involta and is not carrier neutral. Involta intends to run TUSIX until it grows large enough to be self-supporting over time. When TUSIX grows large enough, Involta will change to a standalone cooperative owned and operated by its participants. If TUSIX never grows, Involta is committed to maintaining the exchange long-term if necessary.
