Ukuhunyushwa kwalesi sihloko kulungiselelwe ngokukhethekile abafundi bezifundo "Unjiniyela Wenethiwekhi". Ukubhalisela izifundo manje sekuvuliwe.

BUYELA ESIKHATHINI ESIKHATHINI ESIYODWA 10MB/S ETHERNET - U-PETER JONES, ETHERNET ALLIANCE KANYE NE-CISCO

Kungase kube nzima ukukukholelwa, kodwa i-10Mbps Ethernet isiphinde yaba isihloko esidume kakhulu embonini yethu. Abantu bayangibuza: “Kungani sibuyela emuva ngawo-1980?” Kunempendulo elula, futhi kithina esasisebenza embonini ngaleso sikhathi, ijwayelekile. Ngaleso sikhathi, ngaphambi kokuba i-Ethernet ibe yonke indawo, ukuxhumana kwenethiwekhi kwakufana nentshonalanga yasendle. Ngayinye yayinezimiso zayo eziyisisekelo, izendlalelo ezibonakalayo, izixhumi, njll. Kodwa-ke, i-IT kusukela ngaleso sikhathi igxilise isethi ewumongo yobuchwepheshe ku-Ethernet, ehlinzeka ngokuxhumana okungenazihibe ezigidini zezigidi zabantu.

Uma ngibheka usilingi ehhovisi lami, ngibona izindawo zokufinyelela ezingenantambo ezixhumeka ku-Ethernet. Ngizophinde ngibone izinkomba, izinzwa zokushisa, amadivaysi e-HVAC, ukukhanya kokuphuma kanye nezinye izinhlobo eziningi zamadivayisi nazo ezingakwenzi lokhu. Izwe "Lobuchwepheshe Bokusebenza" libukeka njenge-IT ngeminyaka yama-90s, linohlu olubanzi lwezendlalelo ezingokwenyama nezimiso eziyisisekelo kangangokuthi kubonakala sengathi wonke umuntu uzenzele owakhe (nakhu ukuxhumana).

I-10 Mbps Single Pair Ethernet (10SPE) yagunyazwa yi-IEEE ngoNovemba 2019, yengeza izicaciso ezimbili zesendlalelo esibonakalayo ukuze kusekelwe idatha namandla angaphezu kuka-1000 m wentambo yethusi ephothiwe eyodwa ephothiwe, kanye nokuxhunywa kwezixhumanisi eziningi ezinamanodi angu-8 angaphezu kuka-25. m ikhebula.. Lezi zibaluli ziyenza ifaneleke ngokukhethekile ukunika amandla i-Ethernet ngaphakathi kwezakhiwo namanethiwekhi ezishintshayo zezimboni. Iphrojekthi ye-Advanced Physical Layer (APL) isuselwe ku-10SPE yezinhlelo zokusebenza zendawo eziyingozi.

I-10SPE yathuthukiswa ukuze ihlangabezane nezidingo zabasebenzisi emkhakheni wokwakha ezishintshayo nezishintshayo zezimboni nokwenza lula nokusheshisa ukushintshela ku-Ethernet. Lokhu kwenza ukwamukelwa kwezivumelwano ezikhona zenethiwekhi namasevisi kube inkinga elula ukuyixazulula, okuvumela umhlaba we-OT ukuthi uzuze eminyakeni engama-30 yokuqanjwa kabusha kwe-IT. Imboni manje isinethuba lokwakha ingqalasizinda yenethiwekhi eyodwa, ejwayelekile yezinsiza.

Njengoba i-Ethernet iba neminyaka engama-40, bengijabule ngesivinini kusukela ezinsukwini zakuqala.

I-ETHERNET: I-GLOBAL CONNECTIVITY TECHNOLOGY - NATHAN TRACY, ETHERNET ALLIANCE AND TE CONNECTIVITY

U-2020 uzoletha esinye isinyathelo sokuziphendukela kwemvelo ekukhuleni nasekubuseni kwe-Ethernet njengobuchwepheshe bezokuxhumana bomhlaba wonke. Ubuchwepheshe obufanayo obuyisisekelo obunikeze ukuxhumana kwe-LAN okungabizi kakhulu emkhakheni wehhovisi eminyakeni engu-40 edlule iyaqhubeka nokuthola indlela eya ezimakethe ezintsha njengoba wonke umuntu efuna ukuzuza ezindlekweni, ekusebenzeni nasekuguquguqukeni okunikezwa yi-Ethernet.

Izinhlelo zokusebenza ezintsha ezizoveza izixazululo ze-Ethernet ngo-2020 zifaka amanethiwekhi e-Ethernet anezintambo ezimotweni zokuhlala nezentengiso ngesivinini esingaphezu kwe-10 Gbps, kanye nokuthuthukiswa kwamanethiwekhi okukhanya e-Ethernet embonini yezokuthutha. Iningi seliyazi ngokwakhiwa kwezimoto ezizimele kanye nezidingo zazo. Kodwa-ke, izinzwa, amakhamera kanye nezinhlelo zokulawula ezizokwenza isimangaliso esinjalo sobunjiniyela kuzodinga futhi inethiwekhi ye-Ethernet esebenza kahle ukuvikela abahlali, okungase futhi kunikeze zonke izinzuzo zenethiwekhi zokulawula isimo sezulu ngasinye kanye nokuzijabulisa okulalelwayo nevidiyo okuhlukile. Ngesikhathi esifanayo, inethiwekhi kufanele iqinisekise ukuthi ithrafikhi ehlobene nokuvikeleka ibekwa phambili ngaphezu kwethrafikhi ehlobene nokuzijabulisa..

Mayelana nezicelo zezimboni, ezentengiselwano, ezezimoto nezasekhaya, sizobona ukwanda ekusebenzeni okushiwo kwe-Power over Ethernet (PoE) njengoba izinketho ezintsha ze-PoE zibhalwa phansi futhi zilethwe ezimakethe ngezinhlelo eziningi ezihlukene zezinhlelo zokusebenza nezinhlelo - kusukela ezakhiweni ezihlakaniphile kuye kuye. izinto zikagesi kanye Ne-inthanethi Yezinto, izinzwa nezilawuli. Ukuqinisekisa ukuthi imikhiqizo ye-PoE ekhangiswa njengoba ihlangabezana nalawa mazinga okusebenza ihlolwe amalabhorethri ezinkampani zangaphandle eziqinisekisiwe, i-Ethernet Alliance izokwethula isigaba esilandelayo sohlelo lwayo lwesitifiketi se-PoE. Enye indawo yokwamukelwa ngokushesha kobuchwepheshe obusha be-Ethernet isezinhlelweni zokuxhuma amakhaya ethu namabhizinisi kunethiwekhi eyinhloko ngokuthuthukiswa kobuchwepheshe besizukulwane esilandelayo sePassive Optical Network (PON), obuzoletha isivinini esihlanganisiwe esingu-50 Gbps kuwo wonke amanethiwekhi. ukufika okungenani ku-50 km.

Amanani amasha aphezulu edatha ye-Ethernet azophinde eze emakethe ukuze ahlangabezane nezidingo zezinhlelo zokusebenza ezintsha ezidinga amavidiyo afinyeleleka ngamanethiwekhi amafu. Ukuze kufaniswe amanani edatha afana no-100 Gbps, 200 Gbps kanye no-400 Gbps, ochwepheshe bathuthukisa izinto ezintsha nezakhiwo ezintsha ezizovumela lezi zivinini ukuthi zidlule kulokho obekungenzeki ngaphambili. Sisebenzisa amathuluzi okumodela anamandla nokwakha kokuhlangenwe nakho okudlule, kodwa ngezinto ezintsha, sizobona imishini ye-Ethernet, amamojula optical, izixhumi nezintambo ezivumela i-hyperscale noma ama-opharetha esikhungo sedatha yamafu ukuthi akhuphukele kumazinga amasha okusebenza futhi alethe izinsizakalo ezintsha.

Ngempela, u-2020 ngeke nje kube unyaka we-IEEE 802.3 eguqula iminyaka engama-40, kodwa futhi unyaka wokunwetshwa okuqhubekayo nokukhula kwezinhlelo zokusebenza ze-Ethernet zesizukulwane esilandelayo, ukusebenza, namazinga edatha.

I-ETHERNET IYAQHUBEKA NENWEBE EZEMAKETHENI EZINTSHA - U-JIM THEODORAS, ETHERNET ALLIANCE KANYE NO-HG GENUINE USA

Ngo-2020, i-Ethernet izoqhubeka nokunwebeka ibe izimakethe ezintsha nezinhlelo zokusebenza. I-Ethernet kancane kancane ithatha indawo yezivumelwano eziningi ezikhethekile ngenxa yezinzuzo zayo eziningi nezinga lokonga. Futhi njengoba izidingo zomkhawulokudonsa ziqhubeka zikhula kakhulu, i-Ethernet akudingekile nje ukuthi isheshe, kodwa futhi iqhubekele kumafomethi wokumodeshithi ayinkimbinkimbi kanye nokufana okukhulu. Esikhundleni samabhithi ngomzuzwana, manje sikhuluma ngezinga le-baud; amashaneli e-serial manje asengamashaneli e-N-serial anezimpawu zozimele ezakhelwe ngaphakathi ukuze kuqinisekiswe ukuqondana. Uma sibuyela emuva futhi sibheka isithombe esikhulu, i-Ethernet iguqukile isuka kusixhumanisi sokuxhumana sephoyinti ukuya endaweni yaya esisekelweni samanethiwekhi ekhompyutha asabalalisiwe yonke indawo..

Ngemininingwane eyengeziwe, u-2020 uzoba esinye ingqopha-mlando ku-Ethernet ngokwethulwa komugqa womkhiqizo we-112 Gbps. Nakuba i-100 Gigabit Ethernet ingeyona into entsha, ukufeza leli jubane kuma-serial links akwenzi kutholakale isizukulwane sesithathu semikhiqizo ye-100 Gigabit Ethernet ethuthukisiwe, kodwa futhi kwenza isizukulwane sesibili sama-400 Gigabit Ethernet kanye ne-800 Gigabit yokuqala ngomzuzwana. Ku-ecosystem ye-Ethernet, yonke into kuyodingeka igxumele phambili ukuze isebenze ngokushesha, ngobubanzi, nangamafomethi okumodeshithi ayinkimbinkimbi kakhulu. Isizukulwane sokuqala sama-400-Gigabit ama-transceiver optical weklayenti asekelwe ku-8x28Gbaud PAM4 sizoqala ukuthunyelwa. Ngesikhathi esifanayo, amaklayenti okuqala angu-800 Gigabit/s azoboniswa ku-8x100 Gigabit Ethernet kanye ne-2x400 Gigabit Ethernet. Isithembiso sezixhumanisi ze-serial ezishibhile ngendlela ye-400G-ZR ekugcineni sesizofezeka.

Njengoba ama-transceiver amaningi optical kanye nezintambo ezibonakalayo ezisebenzayo zisetshenziswa kumanethiwekhi endawo, kunengqondo kuphela ukunciphisa phezulu nokuxhuma ngokuqondile ama-optical kuma-silicon ICs ngaphakathi kwale micu. Ama-optics ahlanganiswe ngokuhlanganisiwe asekude nokulungele ukukhiqizwa, kodwa ngo-2020, umsebenzi obalulekile uzobe usenzeka ngemuva kwezigcawu njengoba imboni ye-Ethernet ishintsha imisipha yayo yobuchwepheshe kanye nezimali zentuthuko ekuhlanganiseni ukuxhumana okubonakalayo ngqo ku-silicon die.

UKUFUNDA KWE-ETHERNET ECOSYSTEM KANYE NE-CLOUD MACHINE - ROB STONE, ETHERNET ALLIANCE KANYE NE-BROADCOM

Ukukhula komthamo wenethiwekhi yomhlaba wonke kuyo yonke imikhakha bekulokhu kuqhutshwa izinto ezimbili ezibalulekile; ukwengeza abasebenzisi nokungeza izinhlelo zokusebenza ezintsha. Ngenkathi inani labasebenzisi liqhubeka nokukhula, liyancipha ngenxa yezidingo zomkhawulokudonsa eziqhutshwa izinhlelo zokusebenza ezintsha ezidinga ukusetshenziswa kobuchwepheshe obusha benethiwekhi ukuze kuhlangatshezwane nesidingo. Isigaba esisodwa esinjalo sohlelo esithuthukisa ukukhula okukhulu eminyakeni yamuva nje ubuhlakani bokwenziwa nokufunda komshini (ML), ikakhulukazi amanethiwekhi ajulile we-neural.

Ukukhipha uhlelo lwe-ML kubandakanya izigaba ezimbili. Okokuqala, amamodeli enethiwekhi ye-neural adinga ukuqeqeshwa kusetshenziswa idathasethi yokuqeqeshwa. Uma amamodeli aqeqeshiwe etholakala enembe ngokwanele, adluliselwa ezinjinini zokucatshangelwa, lapho izinhlelo zokusebenza zokugcina zingasebenzisa imodeli eqeqeshiwe ukuze zibikezele (noma "i-infer") imiphumela uma kubhekwa ukuhlukaniswa kwedatha yangaphandle noma imibuzo..

Ukuze kusheshiswe inqubo yokuqeqeshwa kwe-ML, ukufanisa kusetshenziswa okubandakanya izindawo ezimbalwa zokuqeqesha ezihlukene. Lokhu kubangela izimfuneko zenethiwekhi eziqinile zokusabalalisa idatha yokuqeqeshwa phakathi kwama-node, kanye naphakathi nenqubo yokuqeqesha eyalandela njengoba imingcele ishintshaniswa phakathi kwama-node ukuze kuthuthukiswe ukunemba kwemodeli. Ngesikhathi sokucatshangelwa, uhlelo lokusebenza lokugcina lugcizelela ukubuyisela umphumela ngokushesha ukuze kuncishiswe ukubambezeleka okubonakalayo kumsebenzisi wokugcina, ngakho-ke ukubambezeleka okuphansi kubalulekile. Ngenxa yalezi zizathu, bonke opharetha abakhulu be-hyperscale manje sebekhiphe ihadiwe yabo ye-ML, futhi abanye banikela nge-cloud ML njengesevisi yezinhlelo zokusebenza zabasebenzisi bokugcina. Ukuncintisana phakathi kwezinsizakalo ezahlukene zamafu e-ML kuphoqa opharetha ukuthi baqhubeke nokutshala imali ekuthuthukisweni kwengqalasizinda yenethiwekhi ukuze bahlale bencintisana, okubuye kuqhubekisele phambili umphakathi we-Ethernet ukuthi uphendule kubuchwepheshe obusekela izidingo ezikhulayo zomkhawulokudonsa nezinselele zokugcina amandla amukelekayo kanye nephrofayili yezindleko.

Nokho, lezi zinhlelo zangaphakathi ze-ML azinamsebenzi ngaphandle uma idatha yokokufaka ingaqoqwa futhi ithunyelwe ezinjinini zokucabanga ukuze kwenziwe izibikezelo. Amadivayisi afana nezimoto ezizimele, i-IoT yezimboni kanye namakhaya ahlakaniphile, amahhovisi namadolobha asebenzisa isethi ehlukahlukene yobuchwepheshe bokuxhuma, okungenantambo (amanethiwekhi endawo yomuntu siqu kanye namanethiwekhi endawo noma i-WiFi), anezintambo ezihlanganisa ukusetshenziswa kobuchwepheshe baMandla phezu kwe-Ethernet, namaselula. (LTE kanye ne-5G). Bonke lobu buchwepheshe busebenzisa i-Ethernet ecosystem ukudala izixazululo ezingabizi, ezisebenzisana kakhulu.
