An IX (Internet Exchange) allows networks to interconnect on an open-access ethernet fabric -- providing low-latency, high-bandwidth, cost-effectively, in a locale.
Networks can exchange traffic faster and better. ISPs, transit providers, DNS services, and content networks will congregate -- it is sensible to interconnect locally with high-bandwidth at low-latency.
Traffic exchange is facilitated by BGP (Border Gateway Protocol). Networks must have an AS (Autonomous System) number to announce their routes to each other. A looking glass shows the routes carried.
YYCIX has no membership or port fees, and only requires delivery of a SFP optic for our switch. YYCIX was built with donations and is operated by volunteers. Consider contributing hardware or money.
