Passage: Open Shortest Path First (OSPF) rakagadzirwa somunhu womukati gedhi dzakati (IGP), kushandiswa mune kuzvionera gadziriro akadai Local Area Network (LAN). It anoshandisa Dijkstra kwakaita interrouting algorithm, aizivikanwawo sezvo pfupi nzira yokutanga (SPF) algorithm. Somunhu kubatana-mamiriro routing dzakati yakavakirwa kubatana-mamiriro algorithm yakatanga nokuda ARPANET muna 1980 uye IS-IS routing dzakati. OSPF yakatanga standardized muna 1989 sezvo RFC 1131, izvo zvino kuzivikanwa sezvo OSPF shanduro 1. The basa kukura nokuda OSPF kuti codification kwayo sezvo rakavhurika mureza akanga kuitwa zvikurukuru nokuda Digital Equipment Corporation, iyo yakatanga yayo proprietary DECnet dzakati. Routing dzakati OSPF aigona kushandisa interrouting algorithm, aizivikanwawo sezvo shortest nzira routing algorithm.
