Croatian Internet eXchange (CIX) is Croatian national centre for exchange Internet traffic settled in University Computing Centre (Srce) available to all ISPs in Republic of Croatia, equally for commercial and non-commercial or private networks.

By establishing direct communication channels between Croatian Internet Service Providers we significantly reduce the costs of data exchange among Croatian Internet users. CIX members arrange mutual peering for traffic exchange. They are not obliged to exchange traffic with other participants (CIX members). The required routing protocol for peering is BGP (version 4). The corresponding routing registry for the CIX peering documentation is RIPE database. The shared fabric for data exchange is Switched Ethernet.

The purpose of peering is a direct interconnecting of ISPs in order to reduce unnecessary traffic via third networks.
