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, neutral and independent peering point which was created as a free exchange point sponsored only by donations. It continues to run without any re-occurring 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 November 29, 2015 there are 223 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== The core of the Seattle Internet Exchange (SIX) is an Arista Networks 7508 and a Cisco Catalyst 6509 at the Westin Building and an Extreme Networks X670 at KOMO-FM Plaza (formerly Fisher Plaza).〔(【引用サイトリンク】 publisher = Seattle Internet Exchange )〕 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.
