I-NetBIOS ivumela izinhlelo zokusebenza namakhompyutha ukuba axhumane phezu kwe-LAN
Ngamafuphi, i-NetBIOS inikeza amasevisi wokuxhumana kumanethiwekhi wendawo. Isebenzisa iprotocol ebizwa ngokuthi i-NetBIOS Frames (NBF) evumela izinhlelo zokusebenza namakhompyutha kunethiwekhi yendawo (LAN) ukuxhumana ne- hardware yenethiwekhi nokudlulisa idatha yonkana kunethiwekhi.
I-NetBIOS, isifinyezo se-Network Basic Input / Output System, iyinhlangano yezimboni zokuxhumana. Yadalwa ngo-1983 ngu-Sytek futhi isetshenziswa kaningi nge-NetBIOS ngaphezu kwe-TCP / IP (NBT) protocol. Noma kunjalo, lisetshenziselwa amanethiwekhi we- Token Ring , kanye ne-Microsoft Windows.
Qaphela: I- NetBIOS ne-NetBEUI zihlukile kwezobuchwepheshe obuhlobene. I-NetBEUI inikeze ukuqaliswa kokuqala kwe-NetBIOS ngamakhono okuxhumana okungeziwe.
Indlela i-NetBIOS isebenza ngayo nezicelo
Izinhlelo zokusebenza ze-inethiwekhi kunethiwekhi ye-NetBIOS thola futhi zibonane ngamagama abo we-NetBIOS. Ku-Windows, igama le-NetBIOS lihlukile kwegama lekhompyutha futhi lingaba izinhlamvu ezingu-16 ubude.
Izicelo kwamanye amakhompyutha ukufinyelela kwamagama we-NetBIOS ngaphezu kwe- UDP , i- OSI elula yokulandelwa kwendlela yokuthutha yezinhlelo zokusebenza zetlayenti / iseva ezisekelwe ku- Inthanethi Protocol (IP) , nge-port 137 (ku-NBT).
Ukubhalisa igama le-NetBIOS liyadingeka ngohlelo lokusebenza kodwa alusekelwa yi-Microsoft ye- IPv6 . I-octet yokugcina ngokuvamile i-NetBIOS Suffix echaza ukuthi yiziphi izinsizakalo uhlelo olutholakalayo.
I- Windows Internet Naming Service (i-WINS) inikeza amasevisi wokuxazulula igama nge-NetBIOS.
Izicelo ezimbili ziqala iseshini ye-NetBIOS uma iklayenti ithumela umyalo wokuthi "shayela" elinye iklayenti (iseva) ngaphezu kwechweba le- TCP 139. Lokhu kubizwa ngokuthi imodi yeseshini, lapho izinhlangothi zombili ziphuma khona "zithumela" futhi "zamukela" imiyalo yokuletha imiyalezo kuzo zombili izinkomba. Umyalo we-"hang-up" unqamula iseshini ye-NetBIOS.
I-NetBIOS iphinde isekele ukuxhumana okungaxhunyiwe ku-UDP. Izicelo zilalele ku-port ye-UDP 138 ukuthola ama-datagrams we-NetBIOS. Isevisi ye-datagram ingathumela futhi yamukele amadathamitha nokudlulisa amadathamitha.
Ulwazi olungaphezulu ku-NetBIOS
Ukulandela kungenye yezinketho igama lensizakalo elivunyelwe ukuthumela nge-NetBIOS:
- Engeza igama ukuze ubhalise igama le-NetBIOS
- Engeza igama leqembu lifana kodwa ubhalisa igama leqembu le-NetBIOS
- Igama lokususa ukubhalisa igama le-NetBIOS, kungakhathaliseki ukuthi liyigama noma iqembu
- Thola igama ukubuka igama le-NetBIOS kwinethiwekhi
Izinsizakalo zeseshini zivumela lezi zimbangi:
- Shayela ukuqala iseshini ngegama le-NetBIOS
- Lalela uzobona uma kungenziwa umzamo wokuvula iseshini
- I-Hang Up isetshenziselwa ukuvala iseshini
- Thumela kuzothumela iphakhethi phezu kweseshini
- Thumela i-Ack ayifani nokuthumela kepha ayidingi ukuvuma ukuthi ithunyelwe phakathi neseshini
- Thola ukulinda kwepakethe engenayo
Uma kumodi ye-datagram, lawa ma-primitives asekelwa:
- Thumela i-Datagram izothumela i-datagram ngegama le-NetBIOS
- Thumela ukusakaza i-Datagram ngukuthumela i-datagram kuwo wonke amagama obhalisiwe we-NetBIOS kwinethiwekhi
- Thola i-Datagram ilinda iphakethe le-Send Datagram
- Thola i-Broadcast Datagram ilinde iphakethe le-Send Broadcast
