The Seattle Internet Exchange (SIX) is an Internet exchange point in Seattle, USA. Its switch fabric is centered at the Westin Building and extended to KOMO Plaza, Sabey Intergate, and other locations. [3] The SIX is one of the most successful examples of neutral and independent peering points, created as a free exchange point originally sponsored only by donations. The SIX is the most frequently cited model upon which other neutral Internet exchanges are based, and its financial and governance models are often cited as inspiration for other exchanges. It continues to run without any recurring charges to the participants and current major funding comes from one-time 10, 100, and 400 Gbit/s port fees, as well as from voluntary contributions from stakeholders. The SIX is a 501(c)(6) tax-exempt non-profit corporation.

Contents

As of April 21, 2024, there are 370 networks (443 routers) connected to the SIX advertising at least 195,000 (140,000 IPv4, 55,000 IPv6) unique Border Gateway Protocol (BGP) routes. There are two route servers running the Bird Internet routing daemon (BIRD).

Technology

The core of the SIX consists of Arista Networks switches, with a 7808R3, 7512R, and 7508R at the Westin Building, a 7504R3 at KOMO Plaza, and a 7504R at Sabey Intergate. [3] Participants may connect to the SIX core using a 1 Gbit/s, 10 Gbit/s, 40 Gbit/s, 100 Gbit/s, or 400 Gbit/s Ethernet connection (fiber) or to one of several extensions. Extensions are sponsored by colocation facilities or transport providers.

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.

An Internet Protocol address is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. IP addresses serve two main functions: network interface identification, and location addressing.

<span class="mw-page-title-main">IPv6</span> Version 6 of the Internet Protocol

Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion, and was intended to replace IPv4. In December 1998, IPv6 became a Draft Standard for the IETF, which subsequently ratified it as an Internet Standard on 14 July 2017.

The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. BGP is classified as a path-vector routing protocol, and it makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator.

In computer networking, Teredo is a transition technology that gives full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network. Unlike similar protocols such as 6to4, it can perform its function even from behind network address translation (NAT) devices such as home routers.

The Toronto Internet Exchange Community (TorIX) is a not-for-profit Internet Exchange Point (IXP) located in a carrier hotel at 151 Front Street West, Equinix's TR2 data centre at 45 Parliament Street and 905 King Street West in Toronto, Ontario, Canada. As of March 2021, TorIX has 259 unique autonomous systems representing 285 peer connections and peak traffic rates of 1.344 Tbps, making it the largest IXP in Canada. According to Wikipedia's List of Internet Exchange Points by Size, TorIX is the 16th largest IXP in the world in numbers of peers, and 17th in the world in traffic averages. The Exchange is organized and run by industry professionals in voluntary capacity.

<span class="mw-page-title-main">AtlantaIX</span>

The Atlanta Internet Exchange (AtlantaIX) is an Internet Exchange Point situated in Atlanta, Georgia, United States. AtlantaIX is a fast-growing, neutral and independent peering point. The beginnings of the AtlantaIX can be traced back to 1997. The current version of the AtlantaIX was re-established on September 4, 2003 by Michael Lucking, GreatAccess.com, WV Fiber and 56 Marietta Street Partners. AtlantaIX was originally created as a free exchange point sponsored by the donations of the founders. Today AtlantaIX continues to run without any re-occurring charges to the participants. In 2007, one time port fees were instituted to aid in paying for a recently upgraded switch infrastructure. In January 2007, Michael Lucking purchased a new Foundry Networks Jetcore 15000 in order to support 10 Gigabit Ethernet connections. In January 2008 the switch fabric was migrated to a Cisco 6509 in order to support line rate 10 gigabit Ethernet. In early 2008, the AtlantaIX began supporting IPv6.

An IPv6 transition mechanism is a technology that facilitates the transitioning of the Internet from the Internet Protocol version 4 (IPv4) infrastructure in use since 1983 to the successor addressing and routing system of Internet Protocol Version 6 (IPv6). As IPv4 and IPv6 networks are not directly interoperable, transition technologies are designed to permit hosts on either network type to communicate with any other host.

The deployment of IPv6, the latest version of the Internet Protocol (IP), has been in progress since the mid-2000s. IPv6 was designed as the successor protocol for IPv4 with an expanded addressing space. IPv4, which has been in use since 1982, is in the final stages of exhausting its unallocated address space, but still carries most Internet traffic.

<span class="mw-page-title-main">IPv6 address</span> Label to identify a network interface of a computer or other network node

An Internet Protocol version 6 address is a numeric label that is used to identify and locate a network interface of a computer or a network node participating in a computer network using IPv6. IP addresses are included in the packet header to indicate the source and the destination of each packet. The IP address of the destination is used to make decisions about routing IP packets to other networks.
