UStephen Hemminger (unjiniyela we-Microsoft software) muva nje kuhlongozwe ukususa ikhodi ukuphathwa kwephrothokholi I-Linux kernel DECnet. Unjiniyela ukholelwa ukuthi akuyona nje isoftware ephelelwe yisikhathi, kodwa i-DECnet ingeyomnyuziyamu womlando wezivumelwano zekhompiyutha hhayi i-Linux kernel.
wakhumbula lokho I-DECnet ayizange inakekelwe kusukela okungenani ngo-2010 futhi isixhumanisi semibhalo eku-Sourceforge sibonisa ukuthi iyekwa lapho, futhi isiphakamiso sayo sinokusekelwa okuqinile futhi ukususwa kwe-DECnet kuzolula i-Linux kernel ngemigqa yekhodi engaba yizinkulungwane eziyishumi nambili.
Kulabo abasha ku-DECnet, kufanele wazi ukuthi lokhu iyisethi yezivumelwano zenethiwekhi ezithuthukisiwe yi-Digital Equipment Corporation (DEC) enenguqulo yokuqala eyakhishwa ngo-1974.
I-DEC ithuthukise i-DECnet yehadiwe/imikhiqizo yenethiwekhi yesofthiwe esebenzisa i-DIGITAL Networking Architecture (DNA), iqoqo lamadokhumenti asungula izincazelo zesendlalelo ngasinye sezakhiwo futhi achaze izivumelwano ezisebenza kulezo zendlalelo.
Ekuqaleni yenzelwe ukuxhuma ama-microcomputer amabili e-PDP-11, kodwa ekugcineni yaba enye yezakhiwo zokuqala zenethiwekhi yontanga ngeminyaka yawo-1980.
Yabe isihlanganiswe ku-VMS, Isistimu yokusebenza ye-flagship ye-DEC. Lokhu kungenxa yokuthi i-DECnet Phase I yakhululwa ngo-1974 futhi yasekela kuphela ama-PDP-11 ngohlelo olusebenzayo lwe-RSX-11, futhi okuwukuphela kwendlela yokuxhumana etholakalayo kwakuyi-point-to-point. Ngo-1975, iSigaba II sakhululwa ngokusekelwa kwamanodi angama-32 ayenokusebenza okuhlukile komunye nomunye, okuhlanganisa i-TOPS-10, TOPS-20, kanye ne-RSTS. Le nguqulo ibinesilaleli Sokufinyelela Komugqa sokudluliselwa kwamafayela, Iphrothokholi Yokufinyelela Idatha yokufinyelela ifayela elikude, nezici zokuphatha inethiwekhi.
Kodwa ukuxhumana phakathi kwamaphrosesa kwakusenomkhawulo ekuxhumaneni okukhomba-kuya-phuzu, iSigaba III sakhululwa ngo-1980, futhi kulokhu ukusekelwa kwandiswe kuma-node angu-255, nge-point-to-point kanye nezixhumanisi zamaphoyinti amaningi kanye nesici somzila oguquguqukayo wethulwa futhi manje. uhlelo lungaxhumana nezinye izinhlobo zamanethiwekhi, njenge-IBM SNA, ngamasango.
Izigaba IV kanye ne-IV+ zakhululwa ngo-1982 ngokwesekwa kwamanodi afinyelela kwangu-64 futhi zifaka ukusekelwa kwe-Ethernet LAN njengenketho eyinhloko yokuxhumanisa idatha, yingakho. waqhubeka iminyaka embalwa eyengeziwe ukuthuthukiswa nokuthuthukiswa kwayo kodwa kusukela lapho ikhodi ye-DECnet ihlale iyingxenye ye-Linux kernel.
Kodwa manje, kuphakanyiswa ukuthi le khodi kufanele isuswe maduze kusuka ku-Linux kernel.
"Izivumelwano ze-DECnet seziphelelwe yisikhathi, ukuqaliswa kwe-Linux kernel sekuyiminyaka engaphezu kweshumi, futhi ikhodi ingeyemnyuziyamu yomlando kune-kernel eyinhloko," kusho uHemminger eposini ohlwini lwamakheli e-Linux kernel. Umthuthukisi we-Linux uDavid Laight uphinde wathi, "Kwakungasasebenzi kahle ngenkathi ngibhala abashayeli be-Ethernet ekuqaleni kwawo-1990."
"Kuyamangaza ukuthi ukwesekwa kwakhelwe kuLinux kwasekuqaleni," engeza. Umnakekeli wokugcina wekhodi ye-DECnet kwakungu-Red Hat's Christine Caulfield, owaba intandane ikhodi ngo-2010. Lolu shintsho akufanele lukhathaze abantu abaningi: I-VMS ingeyokugcina, noma ivamile, isistimu yokusebenza yokusebenzisa i-DECnet, futhi i-VMS ine-TCP/IP kusekelwa isikhathi eside. Khumbula ukuthi nakuba ubukhona bayo bulibaleka ngokushesha namuhla, i-TCP/IP akuyona yodwa iphrothokholi yenethiwekhi ekhona futhi, maphakathi nawo-1990, kwakungeyona ngisho iphrothokholi evelele.
Kuhle ukusho ukuthi akuyona iphrothokholi yokuqala noma yokugcina ehlongozwayo ukuthi isuswe ku-Kernel, njengoba singakhumbula ukuthi i-AppleTalk inqanyulwe yi-Mac OS X kusukela kunguqulo 10.6 "Ingwe Yeqhwa", ngakho izonyamalala maduze.
Okwamanje, ukususwa okuhlongozwayo kwe-DECnet Ikhodi ye-Linux kernel kusaxoxwa ngakho ohlwini lwamakheli. Nokho, uma kubhekwa ukwesekwa ekujabulelayo, kuwukubheja okuphephile ukuthi le khodi eseyizintandane isikhathi eside izokhishwa maduze esihlahleni.
