Ndiyabulisa bafundi bam abathandekayo be-cyber!
Kweli thuba litsha, mabathethe kancinci malunga IiNethiwekhi kunye neSoftware yasimahla ukwenza ukukhankanywa kwesoftware ethembisayo eya iduma ngakumbi kwaye isetyenziswa kwihlabathi liphela yonke imihla, yile I-OpenDayLight.
I-OpenDayLight Yiprojekthi ye Vula Umnikezi (Vula Umnikezi) ejolise ekukhawuleziseni nasekukhuthazeni ukuhanjiswa kwezinto ezintsha kuyilo nasekumiliselweni komgangatho ovulekileyo nosebenza elubala IiNethiwekhi eziChaziweyo zeSoftware (i-RDS), okt I-Software-Defined Networking (SDN). Okwangoku le projekthi inenkxaso yeenkampani ezinkulu nezaziwayo njenge:
- Inethiwekhi,
- ibrocade,
- Cisco,
- ICitrix,
- Nokia,
- IBM,
- Iinethiwekhi zeJuniper,
- IMicrosoft,
- I-NEC,
- redhat,
- VMware
Kutshanje bakhuphe ingxelo yabo yamva nje yenkqubo ebizwa Beryllium.
I-OpenDayLight uzenza ngathi uxelisa ntoni hadoop wenze kwimarike ye I-BigData ke ngoku ntoni OpenStack yenza kwifayile ye- Ukhomyutha yamafu. Ngamanye amagama, ukuba liqonga elivulekileyo elisebenzisa zonke iinkampani, ukuthintela usetyenziso (lobunini) lwezicelo (iinkqubo) ekuthinteleni ukukhula kweemarike kwaye kwangaxeshanye kuncitshiswe iindleko zophuhliso.
La umbono kunye ilifu Kwiminyaka yakutshanje babenobuchwephesha obunobuchwephesha, kodwa ngoku ithuba lelothungelwano, oluhleli luhleli ndawonye kunye nezixhobo ezisekwe kwizixhobo zokusebenza, kude kube ngoku. Eqale ukutshintsha ngokufika kwe- I-Software Defined Networking (i-RDS) -I-Software Defined Networking (i-SDN), ethembisa ukusasazeka okukhulu, ubhetyebhetye, kunye nenkqubo ngokususa uninzi lwenethiwekhi yobukrelekrele itshintshela kunye imizila kwaye uyifaka isoftware esekwe kwisoftware.
I-OpenDayLight uzimisele ukuba yi- iqonga le-SDN eliqhelekileyo nelivulekileyo Ndidibanise indawo ezinje ngeqonga lolawulo okanye iiprotocol zokusetyenziswa kwenethiwekhi, ujongano lomsebenzisi, iswitshi ebonakalayo okanye ujongano lomzimba lwesixhobo.
Olona ncedo luphambili kwesi sicelo kukuba isusa imiqobo yokwamkelwa, njengoko eminye imibutho ingafuni ukuzibophelela kumenzi othile ogcina ethintela ikamva labo. Ukuba liqonga eliqhelekileyo, iinkampani ziya kuba nakho ukukhetha itekhnoloji kubavelisi abohlukeneyo eya kuthi isebenzisane.
Ngokukodwa IiNethiwekhi eziTshintshayo ezinkulu, iBrocade, iCisco, iCitrix, iNokia, IBM, iiNethiwekhi zeJuniper, iMicrosoft, iNEC, iRedHat, kunye neVMware ngamalungu platinum y igolide (abasunguli abaphambili) beprojekthi, ngubani nikela ngesoftware kunye nezixhobo zobunjineli kule Proyect Vula Umnikezi kwaye iya kunceda ukucacisa ukuvula iqonga le-SDN, njengoko kuchaziwe ngokusemthethweni.
Kwiakhawunti ezichazayo I-OpenDayLight Yiyo Umlawuli weOpenFlow, ethi yona ibe ngu umthetho olandelwayo ovumela iserver ukuba ixelele utshintsho lwenethiwekhi apho zithunyelwa khona iipakethi. Kwinethiwekhi nganye yemveli, Iswitshi nganye inesoftware yobunini (yobunini) echaza imigaqo emayilandelwe (into emayenziwe). Con OpenFlow iipakethe izigqibo zokufuduka zibekwe kwindawo enye ukuze uthungelwano lube ishedyuli ezimeleyo kutshintsho lomntu kunye nezixhobo zedatha.
Ukufaka I-OpenDayLight unokukhokelwa yi Isikhokelo esisemthethweni soMvelisi ucofa Apha, kwaye ndithembele koku Ibhlog yeWordPress malunga nesicelo ngokunqakraza Apha.
Kwaye ziyintoni ngokwenene iiNethiwekhi ezichaziweyo zeSoftware?
Las SDN yindlela yokusondela kunxibelelwano apho thatha ulawulo isicelo sesoftware esibizwa ngokuba ngumqhubi kwaye hayi uthungelwano lwenethiwekhi yehardware.
Xa iphakheji ifika kwifayile ye- tshintsha Kwinethiwekhi yemveli, imigaqo edityanisiweyo kwifayile ye- firmware switch yabucala kunye evaliweyo baxela ngokufanayo apho banokuhambisa ipakeji. Inkqubo ye- guqula ithumela ipakethi nganye kwindawo enye ngendlela enye kwaye inyanga zonke iipakethi ngendlela efanayo. Kwinkampani, guqula bulumko (kulawulwa) yenzelwe cizicelo zesekethe ezihlanganisiweyo ezithile (SO C) ezintsonkothile ngokwaneleyo ukuba zinokuqonda iintlobo ezahlukeneyo zeephakeji kwaye uziphathe ngokwahlukileyo, kodwa ezi guqula zinokubiza kakhulu.
Ku SDN, un ISysAdmin (UMlawuli weNethiwekhi) unakho ukumila kwetrafikhi ukusuka kwikhonsoli yolawulo esembindini ngaphandle kokuchukumisa guqula umntu ngamnye. Umlawuli unako tshintsha nawuphi na umthetho we guqula network xa ifuneka, ukunika okanye ukususa okuphambili, okanye ukuthintela iintlobo ezithile zeepakethi ngenqanaba lokulawula elinenkcukacha kakhulu.
Oku kuluncedo ngakumbi kwifayile ye- uyilo olwahlukeneyo (uyilo oluninzi lwabaqeshi) de Ukhomyutha yamafu kuba ivumela umlawuli phatha imithwalo yezithuthi ngokuguquguqukayo nangokufanelekileyo. Ngokusisiseko, oku kuvumela uMlawuli weNethiwekhi Sebenzisa utshintsho oluncinci kunye nexabiso eliphantsi kwaye ube nolawulo ngakumbi kunakuqala ngaphezulu kokuhamba kwetrafikhi yenethiwekhi.
Ku- SDN ngamanye amaxesha kubhekiswa kubo njenge "Umbulali weCisco" kuba ivumela Iinjineli zeNethiwekhi Ukuxhaswa kwendwangu yokutshintsha ngehardware yabathengisi abaninzi kunye nee-ICs zesicelo esithile. Okwangoku eyona nto idumileyo yokudala ifayile ye- SDN ngumgangatho ovulekileyo OpenFlow, njengoko besifundile ngaphambili ivumela KwiSysAdmin ulawulo iitafile zokuhambisa ifom ekude.
