Lero takonzera owerenga athu mitundu yosiyanasiyana ya owongolera a SDN omwe amathandizidwa ndi ogwiritsa ntchito GitHub ndi mabungwe akuluakulu otseguka monga Linux Foundation.

OpenDaylight ndi nsanja yotseguka, yokhazikika yogwiritsira ntchito ma netiweki akuluakulu a SDN. Mtundu wake woyamba unatulutsidwa mu 2013 ndipo pambuyo pake unakhala gawo la Linux Foundation. Mu Marichi chaka chino, chida, ndipo chiwerengero cha ogwiritsa ntchito chadutsa biliyoni.
Woyang'anira akuphatikizapo dongosolo lopangira maukonde enieni, mapulagini othandizira ma protocol osiyanasiyana, ndi zofunikira zogwiritsira ntchito nsanja ya SDN yodzaza. Zikomo API kuphatikiza OpenDaylight ndi olamulira ena. Pachimake yankholo linalembedwa mu Java, kotero mutha kugwira nawo ntchito pamakina aliwonse omwe ali ndi JVM.
Platform zonse mu mawonekedwe a ma phukusi a RPM ndi ma binary builds onse, komanso zithunzi za makina owonera zomwe zakonzedwa kale kutengera Fedora ndi UbuntuMukhoza kuzitsitsa. pamodzi ndi zolemba. Ogwiritsa ntchito amadziwa kuti kugwira ntchito ndi OpenDaylight kungakhale kovuta, koma Pali maupangiri ambiri opangira chida.
Ichi ndi chimango chotseguka chopangira owongolera a SDN. Ndi SDK kutengera OpenDaylight nsanja. Cholinga cha pulojekiti ya Lighty.io ndikufewetsa ndikufulumizitsa chitukuko cha mayankho a SDN ku Java, Python ndi Go.
Chimangochi chimapereka zida zambiri zochepetsera malo a SDN. Makamaka, Lighty.io imakupatsani mwayi wotsanzira zida zapaintaneti ndikuwongolera machitidwe awo. Ndikoyeneranso kuzindikira chigawocho - imagwiritsidwa ntchito kuwonetsa ma topology a network.
Pezani kalozera pakupanga mapulogalamu a SDN pogwiritsa ntchito Lighty.io in . Ibid. mapulogalamu omwe alipo papulatifomu yatsopano.
Kuwerenga pamutuwu patsamba lathu lamakampani:
Iwo - ndi gulu la mapulogalamu oyang'anira OpenFlow network. Zomangamanga zamakina ndizokhazikika ndipo zimathandizira masiwichi angapo owoneka ndi thupi. Yankho lapeza kale ntchito pakupanga ntchito yosinthira yokhazikika yozikidwa pa SDN - , komanso kusungirako komwe kumatanthauzidwa ndi mapulogalamu .
Ndi ,Floodlight imaposa OpenDaylight pamanetiweki odzaza kwambiri. Koma pamanetiweki okhala ndi katundu wochepa komanso wapakati, Floodlight imakhala ndi latency yayikulu. Pezani kalozera woyikamo .
Seti yazinthu zamapulogalamu zosinthira ma switch a OpenFlow. OESS imapereka mawonekedwe osavuta a intaneti kwa ogwiritsa ntchito komanso API yamawebusayiti. Ubwino wa yankho ndikusinthiratu kumayendedwe osunga zosunga zobwezeretsera pakalephera komanso kupezeka kwa zida zowonera. Zoipa: Thandizo la chiwerengero chochepa cha mitundu yosinthira.
Kuyika kwa OESS ndi kalozera wamasinthidwe ali munkhokwe .

Uyu ndi wowongolera yemwe milingo yake yotsatiridwa pa netiweki imayimiriridwa ngati mafunso a SQL. Atha kuwongoleredwa kudzera pamzere wolamula. Ubwino wa njirayo ndikuti, chifukwa cha SQL, mafunso amatumizidwa mwachangu. Kuphatikiza apo, chidachi chimakuthandizani kuti muzitha kuwongolera magawo angapo azinthu zotsatiridwa kudzera pakuyimba kwake. Kuipa kwa yankho kumaphatikizapo kusowa kwa maonekedwe ndi kufunikira kophunzira mzere wolamula.
Maphunziro a pang'onopang'ono ogwirira ntchito ndi Ravel angapezeke pa polojekiti. Izi zonse zimaperekedwa mu mawonekedwe ofupikitsidwa. .
Chida chofotokozedwa ndi mapulogalamu poteteza maukonde enieni. Imayendetsa kutumizidwa kwa ma firewall, machitidwe oletsa kulowerera ndi ma antivayirasi. OSC imagwira ntchito ngati mkhalapakati pakati pa woyang'anira chitetezo ndi ntchito zosiyanasiyana zachitetezo ndi malo. Nthawi yomweyo, imatha kugwira ntchito ndi multicloud.
Ubwino wa OSC ndikuti sichimangiriridwa ndi mapulogalamu enaake kapena zinthu za Hardware. Komabe, chidacho chidapangidwa kuti chizigwira ntchito ndi ma network akuluakulu amakampani. Pachifukwa ichi, sizingatheke kuti zigwirizane ndi zosowa zoyambira.
Kalozera woyambira mwachangu angapezeke .
Iyi ndi njira yoyendetsera ma network a SDN ndi zigawo zake. Chodabwitsa chake ndikuti chimaphatikiza magwiridwe antchito a SDN controller, network ndi seva OS. Chifukwa cha kuphatikiza uku, chidachi chimakupatsani mwayi wowunika zonse zomwe zimachitika pamanetiweki ndikuthandizira kusamuka kuchokera ku zomangamanga kupita ku SDN.
"Bottleneck" wa nsanja angatchedwe chitetezo. Malinga ndi 2018, ONOS ili ndi zovuta zingapo zosasinthika. Mwachitsanzo, kukhala pachiwopsezo cha DoS ndikutha kuyika mapulogalamu popanda kutsimikizika. Zina mwa izo zidasinthidwa kale; opanga akugwirabe ntchito zina. Ponseponse, kuyambira 2015 nsanja zosintha zambiri zomwe zimawonjezera chitetezo cha chilengedwe.
Mukhoza kukopera chida pa boma . Palinso maupangiri oyika ndi maphunziro ena.
Ntchitoyi kale inkatchedwa OpenContrail. Koma idasinthidwa dzina pambuyo poti idatengedwa ndi Linux Maziko. Tungsten Fabric ndi pulogalamu yowonjezera yogwiritsira ntchito ma network yomwe imagwira ntchito ndi makina enieni, ntchito zopanda zitsulo, ndi zotengera.
Pulagiyi imatha kuphatikizidwa mwachangu ndi zida zoimbira zodziwika bwino: Openstack, Kubernetes, Openshift, vCenter. Mwachitsanzo, kutumiza Tungsten Fabric ku Kubernetes Mphindi 15. Chidachi chimathandiziranso ntchito zonse zachikhalidwe za olamulira a SDN: kasamalidwe, mawonekedwe, kasinthidwe ka netiweki ndi . Ukadaulo uli kale ntchito m'malo opangira data ndi mitambo, monga gawo la SDN stacks yogwira ntchito ndi 5G ndi Edge computing.
Nsalu ya Tungsten ndiyabwino kwambiri OpenDaylight, kotero yankho liri ndi zovuta zomwezo - ndizovuta kudziwa nthawi yomweyo, makamaka pogwira ntchito ndi zotengera. Koma apa ndi pamene malangizo amakhala othandiza. ndi zinthu zina zowonjezera mu .
