olemus
OSI mudeli kiht 3, mis tagab
- loogilise adresseerimise
- naabersõlmeaadresside põhjal marsruutimise
- sõnumite tükelduse ja taaskooste
- teenusekvaliteedi valimise
- veatöötluse ja diagnostika

ISO/IEC 2382:
kiht, mis annab transpordikihi subjektidele
vahendid andmeplokkide teisalduseks,
neid subjekte sisaldavate avatud süsteemide vahelise võrgu kaudu marsruutimise ja kommuteerimise teel;
võib kasutada vahesüsteeme
= the layer that provides for the entities in the transport layer the means for transferring blocks of data, by routing and switching through the network between the open systems in which those entities reside
Note. The network layer may use intermediate systems.
