The Seattle Internet Exchange (SIX) is an Internet exchange point in Seattle, USA. It has two locations in the city: the Westin Building and KOMO Plaza (formerly Fisher Plaza). The SIX is a fast-growing,[citation needed] neutral and independent peering point which was created as a free exchange point sponsored only by donations. It continues to run without any recurring charges to the participants and current major funding comes from one-time 10 and 100 Gbit/s port fees. The SIX is a 501(c)(6) tax-exempt non-profit corporation.

As of May 11, 2017 there are 285 routers at the Seattle Internet Exchange (SIX) advertising at least 90,000 unique Border Gateway Protocol (BGP) routes. There are two route servers running Bird Internet routing daemon (BIRD).

Technology[edit]

The core of the Seattle Internet Exchange (SIX) is an Arista Networks 7508E and a 7512R at the Westin Building, an Extreme Networks X670 at KOMO Plaza (formerly Fisher Plaza), and a Cisco Nexus 3524P at Sabey IGX.[3] Participants may connect to the SIX core using a 1 Gbit/s, 10 Gbit/s or 100 Gbit/s Ethernet connection (fiber) or to one of several extensions. Many of the extensions are sponsored by the colocation facilities in the building, and many of these extensions support 100BASE-TX or greater connections.

Both IPv4 and IPv6 peering is available and encouraged at the SIX, with availability dependent on the peer. Jumbo frame peering at 9000-byte maximum transmission unit (MTU) is available.
