29. NFS - Tīkla failu sistēma

29.01 Ievads

Šajā nodaļā mēs aprakstām NFS, tīkla failu sistēmu - citu populāru aplikāciju, kas nodrošina caurspīdīgu failu piekļuvi klientu aplikācijām. NFS stūrakmens ir Sun RPC: attālinātais procedrūru izsaukums, ko mums jāapraksta vispirms. 

Klientu programmām nav jādara nekas īpašs, lai lietotu NFS. Kodols noskaidro, ka fails, kuram klienta programma cenšas piekļūt, ir uz NFS servera un automātiski ģenerē RPC izsaukumu, lai piekļūtu šim failam. 

Mūsu interese par NFS nav visas failu piekļuves nianses, bet šī mehānisma lietojums Interneta protokolos, it īpaši UDP.
