Namuhla silungiselele abafundi bethu ukukhethwa kwezilawuli ze-SDN ezisekelwa ngenkuthalo abasebenzisi be-GitHub nezisekelo ezinkulu zemithombo evulekile njenge-Linux Foundation.

I-OpenDaylight iyinkundla evulekile eyimojuli yokuzenzela amanethiwekhi amakhulu e-SDN. Inguqulo yayo yokuqala yavela ngo-2013, okwathi kamuva yaba yingxenye ye-Linux Foundation. NgoNdasa walo nyaka ithuluzi, futhi inani labasebenzisi lidlule ibhiliyoni.
Isilawuli sihlanganisa isistimu yokudala amanethiwekhi abonakalayo, isethi yama-plugin asekela amaphrothokholi ahlukahlukene, kanye nezinsiza zokuphakela inkundla ye-SDN egcwele isici. Siyabonga ku-API hlanganisa i-OpenDaylight nezinye izilawuli. Umnyombo wesixazululo wawubhalwe ku-Java, ngakho-ke ungakwazi ukusebenza nawo kunoma iyiphi isistimu ene-JVM.
Platform kokubili ngendlela yamaphakheji e-RPM kanye nemihlangano kanambambili yendawo yonke, futhi ngesimo sezithombe ezilungiselelwe ngaphambilini zemishini ebonakalayo esekelwe ku-Fedora no-Ubuntu. Ungazilanda kanye nemibhalo. Abasebenzisi bayaqaphela ukuthi ukusebenza nge-OpenDaylight kungaba nzima, kodwa Kunenombolo enkulu yeziqondiso zokusetha ithuluzi.
Lolu wuhlaka oluvulekile lokuthuthukisa izilawuli ze-SDN. Kuyi-SDK esekelwe kuplathifomu ye-OpenDaylight. Umgomo wephrojekthi ye-Lighty.io ukwenza lula nokusheshisa ukuthuthukiswa kwezixazululo ze-SDN ku-Java, i-Python ne-Go.
Uhlaka lunikeza inani elikhulu lamathuluzi okulungisa isimo se-SDN. Ikakhulukazi, i-Lighty.io ikuvumela ukuthi ulingise amadivayisi enethiwekhi futhi uhlele ukuziphatha kwawo. Kuyafaneleka futhi ukuphawula ingxenye - isetshenziselwa ukubona ngeso lengqondo i-topology yamanethiwekhi.
Thola umhlahlandlela wokudala izinhlelo zokusebenza ze-SDN usebenzisa i-Lighty.io in . Ibid. izinhlelo zokusebenza ezikhona endaweni entsha.
Ukufunda ngesihloko kubhulogi yethu yebhizinisi:
Ku - ngesethi yezinhlelo zokusebenza zokuphatha amanethiwekhi e-OpenFlow. I-architecture yesisombululo i-modular futhi isekela ukushintshwa okubonakalayo nokubonakalayo okuningi. Isixazululo sesivele sitholile isicelo ekuthuthukisweni kwensizakalo yokusakaza e-scalable esekelwe ku-SDN - , kanye nesitoreji esichazwe nge-software .
Ngu ,I-Floodlight idlula i-OpenDaylight kumanethiwekhi anomthwalo omkhulu. Kodwa kumanethiwekhi anemithwalo ephansi nephakathi, i-Floodlight inokubambezeleka okuphezulu. Thola umhlahlandlela wokufaka ku .
Isethi yezingxenye zesofthiwe yokulungiselela amaswishi e-OpenFlow. I-OESS inikeza isixhumi esibonakalayo sewebhu sabasebenzisi kanye ne-API yamasevisi ewebhu. Izinzuzo zesixazululo zihlanganisa ukushintshela ngokuzenzekelayo eziteshini eziyisipele uma kwenzeka ukwehluleka kanye nokuba khona kwamathuluzi okubuka ngeso lengqondo. Ububi: Usekelo lwenani elilinganiselwe lamamodeli wokushintsha.
Igayidi yokufaka neyokumisa ye-OESS isendaweni yokugcina .

Lesi isilawuli amaleveli aso okukhipha inethiwekhi amelwe ngendlela yemibuzo ye-SQL. Angalawulwa ngomugqa womyalo. Inzuzo yale ndlela ukuthi, ngenxa ye-SQL, imibuzo ithunyelwa ngokushesha. Ngaphezu kwalokho, ithuluzi likuvumela ukuthi ulawule izendlalelo eziningi zokufinyezwa ngesici salo se-orchestration esizenzakalelayo. Ububi besixazululo buhlanganisa ukuntula ukubona ngeso lengqondo nesidingo sokutadisha umugqa womyalo.
Isifundo sesinyathelo nesinyathelo sokusebenza neRavel singatholakala kokuthi iphrojekthi. Konke lokhu kwethulwe ngefomethi efingqiwe. .
Ithuluzi elichazwe ngesoftware lokuvikela amanethiwekhi abonakalayo. Isebenzisa ngokuzenzakalelayo ukuthunyelwa kwezibhulamlilo, amasistimu okuvimbela ukungena kanye nama-antivirus. I-OSC isebenza njengomxhumanisi phakathi komphathi wezokuphepha kanye nemisebenzi ehlukahlukene yezokuphepha nezimo. Ngesikhathi esifanayo, iyakwazi ukusebenza nge-multicloud.
Inzuzo ye-OSC ukuthi ayiboshelwe kwisoftware ethile noma imikhiqizo yehadiwe. Kodwa-ke, ithuluzi lenzelwe ukusebenza namanethiwekhi amakhulu ezinkampani. Ngenxa yalesi sizathu, akunakwenzeka ukuthi ifaneleke izidingo zokuqalisa.
Umhlahlandlela wokuqala osheshayo ungatholakala .
Lolu uhlelo lokusebenza lokuphatha amanethiwekhi e-SDN nezingxenye zawo. Okuhlukile kwayo ukuthi ihlanganisa ukusebenza kwesilawuli se-SDN, inethiwekhi ne-OS yeseva. Ngenxa yale nhlanganisela, ithuluzi likuvumela ukuthi uqaphe yonke into eyenzekayo kumanethiwekhi futhi lenze kube lula ukufuduka kusuka ekwakhiweni kwendabuko kuya ku-SDN.
"Ibhodlela" lesiteji lingabizwa ngokuthi ukuphepha. Ngokuvumelana ne 2018, i-ONOS inenani lobungozi obungavaliwe. Isibonelo, ukuba sengozini yokuhlaselwa kwe-DoS kanye nekhono lokufaka izinhlelo zokusebenza ngaphandle kokuqinisekisa. Ezinye zazo sezivele zicishiwe; onjiniyela basasebenza kokunye. Sekukonke, kusukela ngo-2015 yesikhulumi inani elikhulu lezibuyekezo ezikhulisa ukuphepha kwemvelo.
Ungalanda ithuluzi esemthethweni . Kukhona nemihlahlandlela yokufaka nezinye izifundo.
Le phrojekthi phambilini ibibizwa nge-OpenContrail. Kepha yaqanjwa kabusha ngemuva kokuhamba βngaphansi kwephikoβ le-Linux Foundation. I-Tungsten Fabric iyi-plugin ye-virtualization yenethiwekhi evulekile esebenza ngemishini ebonakalayo, imithwalo yensimbi engenalutho neziqukathi.
I-plugin ingahlanganiswa ngokushesha namathuluzi e-orchestration adumile: i-Openstack, i-Kubernetes, i-Openshift, i-vCenter. Isibonelo, ukusebenzisa i-Tungsten Fabric e-Kubernetes Imizuzu engu-15. Ithuluzi futhi lisekela yonke imisebenzi yendabuko yabalawuli be-SDN: ukuphatha, ukubona ngeso, ukucushwa kwenethiwekhi kanye . Ubuchwepheshe sebuvele bukhona uhlelo lokusebenza ezikhungweni zedatha namafu, njengengxenye yezitaki ze-SDN zokusebenza nge-5G ne-Edge computing.
I-Tungsten Fabric ibaluleke kakhulu I-OpenDaylight, ngakho-ke isixazululo sinezinkinga ezifanayo - kunzima ukukuqonda ngaso leso sikhathi, ikakhulukazi lapho usebenza neziqukathi. Kodwa kulapho iziyalezo zisiza khona. nezinye izinto ezengeziwe ku .
