UStephen Hemminger (injineli yesoftware yeMicrosoft) kutsha nje kucetywe ukususa ikhowudi ulawulo lweprotocol Linux kernel DECnet. Injineli ikholelwa ukuba ayisiyiyo kuphela isoftware ephelelwe lixesha, kodwa iDECnet yeyemyuziyam yembali yeeprothokholi zekhompyuter kwaye hayi kwiLinux kernel.
wakhumbula ukuba I-DECnet ayizange igcinwe ukususela ngo-2010 ubuncinane kwaye ikhonkco kumaxwebhu aku-Sourceforge libonisa ukuba iyekwa apho, kunye nesindululo sayo sinenkxaso eyomeleleyo kwaye ukususwa kwe-DECnet kuya kuyenza ibe khaphukhaphu i-Linux kernel malunga neshumi elinesibini lamawaka emigca yekhowudi.
Kwabo batsha kwi-DECnet, kuya kufuneka uyazi ukuba oku yiseti yeenkqubo zothungelwano eziphuhlisiwe yi-Digital Equipment Corporation (DEC) kunye nenguqulelo yokuqala ekhutshwe ngo-1974.
I-DEC iphuhlise iDECnet yehardware/iimveliso zothungelwano lwesoftware ezalisekisa i-DIGITAL Networking Architecture (DNA), ingqokelela yamaxwebhu aseka iinkcukacha zomaleko ngamnye wolwakhiwo kwaye achaze iiprothokholi ezisebenza kwezo maleko.
Ekuqaleni, yaphuhliswa ukudibanisa ii-microcomputers ezimbini zePDP-11, kodwa ekugqibeleni yaba yenye yoyilo lokuqala lwenethiwekhi yontanga ngeminyaka yoo-1980.
Yathi ke yadityaniswa kwiVMS, Inkqubo yokusebenza yeflagship yeDEC. Oku kungenxa yokuba i-DECnet Phase I yakhululwa ngo-1974 kwaye ixhasa kuphela i-PDP-11s kunye ne-RSX-11 inkqubo yokusebenza, kwaye indlela yonxibelelwano ekhoyo yayiyi-point-to-point. Kwi-1975, iSigaba sesi-II sakhululwa ngenkxaso yee-nodes ze-32 ezinokuphunyezwa okuhlukeneyo komnye nomnye, kubandakanywa ne-TOPS-10, TOPS-20, kunye ne-RSTS. Olu guqulelo lwalune-Row Access Listener yokudluliselwa kwefayile, iProtocol yoFikelelo lweDatha yokufikelela kwifayile ekude, kunye neempawu zolawulo lwenethiwekhi.
Kodwa unxibelelwano phakathi kweeprosesa lwalusakhawulelwe kwiikhonkco ze-point-to-point, iSigaba se-III sakhululwa kwi-1980, kwaye ngeli xesha inkxaso yanyuswa ukuya kwii-nodes ze-255, kunye ne-point-to-point kunye ne-multipoint links kunye ne-adaptive routing feature yaziswa kwaye ngoku. inkqubo inokunxibelelana nezinye iintlobo zothungelwano, ezifana ne-IBM SNA, ngamasango.
Izigaba ze-IV kunye ne-IV + zakhululwa kwi-1982 ngenkxaso ukuya kwii-nodes ze-64 kwaye zibandakanya inkxaso ye-Ethernet LAN njengeyona ndlela iphambili yokudibanisa idatha, ngoko ke. yaqhubeka iminyaka embalwa engakumbi uphuhliso nokuphuculwa kwayo kodwa ukusukela ngoko ikhowudi yeDECnet ihleli iyinxalenye yeLinux kernel.
Kodwa ngoku, kucetywa ukuba le khowudi isuswe kungekudala kwiLinux kernel.
"Iiprothokholi ze-DECnet ziphelelwe lixesha, ukuphunyezwa kwe-Linux kernel sele kuyinkedama isithuba esingaphezulu kweshumi leminyaka, kwaye ikhowudi yeyemyuziyam yembali kune-kernel ephambili," utshilo uHemminger kwiposti kuluhlu lokuposa lwe-Linux kernel. Umphuhlisi weLinux uDavid Laight uphinde wathi, "Yayingaphelelwa lixesha xa ndandibhala abaqhubi be-Ethernet ekuqaleni kweminyaka yoo-1990."
“Kuyothusa ukuba inkxaso yakhelwe kwiLinux kwasekuqaleni,” wongeze watsho. Umlondolozi wokugqibela wekhowudi ye-DECnet yayingu-Red Hat's Christine Caulfield, owaba yintandane ikhowudi ngo-2010. Olu tshintsho alufanele lukhathaze abantu abaninzi: I-VMS yeyokugqibela, nokuba yinto eqhelekileyo, inkqubo yokusebenza yokusebenzisa i-DECnet, kwaye i-VMS ine-TCP / IP ixhaswa ixesha elide. Gcina ukhumbula ukuba nangona ubukho bayo bulibaleke ngokukhawuleza namhlanje, i-TCP/IP ayisiyiyo yodwa iprotocol yenethiwekhi ekhoyo kwaye, phakathi kwiminyaka yee-1990, yayingeyiyo neyona ndlela iphambili yomthetho.
Kuyafaneleka ukukhankanya ukuba akusiyo iprotocol yokuqala okanye yokugqibela ecetywayo ukuba isuswe kwi-Kernel, njengoko sinokukhumbula ukuba i-AppleTalk iye yanqunyanyiswa yi-Mac OS X ukususela kwi-version 10.6 "i-Snow Leopard", ngoko iya kunyamalala ngokukhawuleza.
Okwangoku, ukususwa okucetywayo kweDECnet Ikhowudi yekernel yeLinux isaxoxwa kuluhlu lokuposa. Nangona kunjalo, ngenxa yenkxaso eyonwabelayo, kubheji olukhuselekileyo ukuba le khowudi yenkedama ende iya kususwa ngokukhawuleza emthini.
