I-OpenDaylight liqonga lemodyuli elivulekileyo lokuzenzela iinethiwekhi ezinkulu ze-SDN. Inguqulelo yayo yokuqala yavela ngo-2013, eyathi kamva yaba yinxalenye yeSiseko seLinux. NgoMatshi walo nyaka isixhobo, kwaye inani labasebenzisi lidlule ibhiliyoni.
Umlawuli uquka inkqubo yokudala amanethiwekhi angabonakaliyo, isethi yeeplagi zokuxhasa iiprotokholi ezahlukeneyo, kunye nezixhobo zokusebenzisa i-platform ye-SDN epheleleyo. Enkosi kwi-API hlanganisa i-OpenDaylight nabanye abalawuli. Ingundoqo yesisombululo yabhalwa kwiJava, ngoko unokusebenza nayo kuyo nayiphi na inkqubo ene-JVM.
Platform zombini ngendlela yeepakethe zeRPM kunye neendibano zokubini jikelele, kwaye ngokomfanekiso wemifanekiso eqwalaselweyo yoomatshini basekwe kwi-Fedora kunye no-Ubuntu. Unokuzikhuphela kunye namaxwebhu. Abasebenzisi baqaphela ukuba ukusebenza nge-OpenDaylight kunokuba nzima, kodwa Kukho inani elikhulu lezikhokelo zokuseta isixhobo.
Esi sisikhokelo esivulekileyo sokuphuhlisa abalawuli be-SDN. Yi-SDK esekwe kwiqonga le-OpenDaylight. Injongo yeprojekthi yeLighty.io kukwenza lula kunye nokukhawulezisa ukuphuhliswa kwezisombululo ze-SDN kwiJava, iPython kunye neGo.
Isakhelo sinikezela ngenani elikhulu lezixhobo zokulungisa imeko ye-SDN. Ngokukodwa, iLighty.io ikuvumela ukuba ulinganise izixhobo zenethiwekhi kwaye ucwangcise indlela yokuziphatha kwazo. Kukwafanelekile ukuqaphela icandelo - isetyenziselwa ukujonga i-topology yothungelwano.
Fumana isikhokelo ekudaleni izicelo ze-SDN usebenzisa iLighty.io kwi . Ibid. izicelo ezikhoyo kwiqonga elitsha.
Ukufunda ngesihloko kwibhlog yethu yeshishini:
Ngu - ngeseti yezicelo zokulawula iinethiwekhi ze-OpenFlow. Uyilo lwesisombululo luyimodyuli kwaye luxhasa utshintsho oluninzi lwenyani kunye nolwenyama. Isisombululo sele sifumene isicelo ekuphuhlisweni kwenkonzo yokusasaza e-scalable esekelwe kwi-SDN - , kunye nogcino oluchaziweyo lwesoftware .
Ngu ,Isibane sesikhukula sigqwesa i-OpenDaylight kuthungelwano olunomthwalo ophezulu. Kodwa kwiinethiwekhi ezinemithwalo ephantsi kunye nephakathi, i-Floodlight ine-latency ephezulu. Fumana isikhokelo sokuhlohla ngaphakathi .
Iseti yamacandelo esoftware yokumisela iiswitshi ze-OpenFlow. I-OESS inikeza ujongano lwewebhu olulula kubasebenzisi kunye ne-API yeenkonzo zewebhu. Iingenelo zesisombululo zibandakanya ukutshintshela ngokuzenzekelayo kwiitshaneli zokugcina xa kukho ukungaphumeleli kunye nokufumaneka kwezixhobo zokubonisa. I-Cons: Inkxaso kwinani eliqingqiweyo leemodeli zokutshintsha.
Ufakelo lwe-OESS kunye nesikhokelo soqwalaselo kwindawo yokugcina .

Lo ngumlawuli omanqanaba akhe okutsalwa kwenethiwekhi amelwe ngokohlobo lwemibuzo yeSQL. Ziyakwazi ukulawulwa ngomgca womyalelo. Inzuzo yendlela yokuba, ngenxa ye-SQL, imibuzo ithunyelwa ngokukhawuleza. Ukongeza, isixhobo sikuvumela ukuba ulawule iileya ezininzi zokutsalwa ngokusebenzisa i-ochestration yayo ezenzekelayo. Ukungalungi kwesisombululo kubandakanya ukungabikho kokubonwayo kunye nesidingo sokufunda umgca womyalelo.
Isifundo senyathelo ngenyathelo lokusebenza kunye neRavel sinokufumaneka apha iprojekthi. Konke oku kuboniswe kwifomathi efinyeziweyo. .
Isixhobo esichazwe ngeSoftware sokukhusela uthungelwano lwenyani. Yenza ngokuzenzekelayo ukuthunyelwa kwee-firewall, iinkqubo zokuthintela ukungena kunye ne-antiviruses. I-OSC isebenza njengomlamli phakathi komphathi wokhuseleko kunye nemisebenzi eyahlukeneyo yokhuseleko kunye nokusingqongileyo. Kwangaxeshanye, iyakwazi ukusebenza ngemulticloud.
Inzuzo ye-OSC kukuba ayibotshwanga kwisoftware ethile okanye iimveliso zehardware. Nangona kunjalo, isixhobo senzelwe ukusebenza kunye nothungelwano olukhulu lweenkampani. Ngenxa yesi sizathu, akunakwenzeka ukuba ulungele iimfuno zokuqalisa.
Isikhokelo sokuqala esikhawulezayo sinokufunyanwa .
Le yinkqubo yokusebenza yokulawula uthungelwano lwe-SDN kunye namacandelo abo. Ubungcali bayo kukuba idibanisa ukusebenza komlawuli we-SDN, inethiwekhi kunye ne-OS yeseva. Ngombulelo kule ndibaniselwano, isixhobo sikuvumela ukuba ubeke iliso kuyo yonke into eyenzekayo kuthungelwano kwaye wenze lula ukufuduka ukusuka kulwakhiwo lwemveli ukuya kwi-SDN.
"I-bottleneck" yeqonga ingabizwa ngokuba lukhuseleko. Ngoku ka Ngo-2018, i-ONOS inenani lobuthathaka obungabhalwanga. Umzekelo, ukuchaphazeleka kuhlaselo lwe-DoS kunye nokukwazi ukufaka izicelo ngaphandle kokuqinisekiswa. Ezinye zazo sele zipeyishiwe; abaphuhlisi basasebenza kwezinye. Ngokubanzi, ukususela ngo-2015 iqonga inani elikhulu lohlaziyo olonyusa ukhuseleko lokusingqongileyo.
Ungakhuphela isixhobo kwigosa . Kukho kwakhona izikhokelo zokufakela kunye nezinye izifundo.
Le projekthi ibikade ibizwa ngokuba yi-OpenContrail. Kodwa yathiywa ngokutsha emva kokuhamba βphantsi kwephikoβ leSiseko seLinux. I-Tungsten Fabric yiplagi ye-virtualization yenethiwekhi evulekileyo esebenza ngoomatshini ababonakalayo, imithwalo yentsimbi engenanto kunye nezikhongozeli.
Iplagin inokudityaniswa ngokukhawuleza kunye nezixhobo ezidumileyo zomculo: I-Openstack, Kubernetes, Openshift, vCenter. Umzekelo, ukuhambisa i-Tungsten Fabric kwi-Kubernetes Imizuzu eli-15. Isixhobo sikwaxhasa yonke imisebenzi yemveli yabalawuli be-SDN: ulawulo, ukubonwa, ukucwangciswa kwenethiwekhi kunye . Ubuchwephesha sele bukhona isicelo kumaziko edatha kunye namafu, njengenxalenye ye-SDN stacks zokusebenza kunye ne-5G kunye ne-Edge computing.
Tungsten Fabric kakhulu I-OpenDaylight, ngoko ke isisombululo sineengxaki ezifanayo - kunzima ukuqonda ngoko nangoko, ngakumbi xa usebenza nezikhongozeli. Kodwa kulapho imiyalelo iza luncedo. kunye nezinye izinto ezongezelelweyo kwi .
