Reittipalvelimen

Reittipalvelimen, often translated as "route server," is a network device or software that facilitates the exchange of routing information between different autonomous systems (AS) on the internet. Its primary function is to simplify the peering process for network operators. Instead of establishing direct peering sessions with every other network present at an internet exchange point (IXP), a network operator can connect to a reittipalvelimen. The reittipalvelimen then acts as a central hub, distributing routing information from connected networks to all other connected networks. This significantly reduces the number of BGP (Border Gateway Protocol) sessions required, thereby lowering the operational complexity and resource consumption for network administrators.

Reittipalvelimen are typically deployed at IXPs where multiple networks interconnect. By connecting to a reittipalvelimen, a network can advertise its routes to many other networks without the administrative overhead of managing individual peering agreements and BGP sessions. In return, the network receives routing information from other participants through the reittipalvelimen. This mechanism promotes a more efficient and scalable internet infrastructure by encouraging interconnections and reducing the burden on network operators. The use of reittipalvelimen is a common practice in modern internet exchange points worldwide.
