Rov qab mus rau yav tom ntej nrog ib leeg-pair 10MB / S ETHERNET - PETER JONES, ETHERNET Alliance thiab CISCO

Tej zaum nws yuav nyuaj rau ntseeg, tab sis 10Mbps Ethernet tau dhau los ua ib lub ntsiab lus nrov heev hauv peb txoj kev lag luam. Cov neeg nug kuv tias: "Vim li cas peb rov qab mus rau xyoo 1980?" Muaj cov lus teb yooj yim, thiab rau peb cov neeg ua haujlwm hauv kev lag luam thaum lub sijhawm, nws paub zoo heev. Nyob rau lub sijhawm ntawd, ua ntej Ethernet tau dhau los ua thoob plaws, kev sib txuas lus zoo li sab hnub poob qus. Txhua tus muaj nws tus kheej cov txheej txheem, cov txheej txheem lub cev, cov khoom sib txuas, thiab lwm yam. Txawm li cas los xij, txij li thaum IT tau tsom mus rau cov txheej txheem tseem ceeb ntawm Ethernet, uas muab kev sib txuas lus tsis sib haum xeeb rau ntau lab tus tib neeg.

Yog tias kuv saib lub qab nthab hauv kuv qhov chaw ua haujlwm, kuv pom cov ntsiab lus nkag wireless uas txuas rau Ethernet. Kuv tseem yuav pom cov ntsuas ntsuas, ntsuas ntsuas kub, HVAC cov khoom siv, tawm teeb pom kev zoo thiab ntau lwm yam khoom siv uas tsis ua qhov no. Lub ntiaj teb ntawm "Operational Technology" zoo li IT nyob rau hauv lub 90s, nrog xws li ib tug ntau yam ntawm lub cev khaubncaws sab nraud povtseg thiab raws tu qauv uas zoo li yog hais tias txhua leej txhua tus tau invented lawv tus kheej (ntawm no yog qhov kev sib txuas)..

Hauv kev nthuav dav ntxiv, 2020 yuav yog lwm qhov tseem ceeb rau Ethernet nrog kev qhia txog 112 Gbps cov khoom kab. Txawm hais tias 100 Gigabit Ethernet tsis yog tshiab, kev ua tiav qhov nrawm ntawm cov kab txuas txuas tsis tsuas yog ua rau muaj lub cim thib peb ntawm cov nqi-zoo 100 Gigabit Ethernet cov khoom, tab sis kuj ua rau tiam thib ob ntawm 400 Gigabit Ethernet thiab thawj 800 Gigabit ib ob. Hauv Ethernet ecosystem, txhua yam yuav tsum tau dhia mus rau tom ntej kom ua haujlwm sai dua, dav dua, thiab hauv ntau hom kev hloov kho. Thawj tiam ntawm 400-Gigabit tus neeg siv khoom kho qhov muag transceivers raws li 8x28Gbaud PAM4 yuav pib xa khoom. Nyob rau tib lub sijhawm, thawj 800 Gigabit / s cov neeg siv khoom yuav raug pom hauv 8x100 Gigabit Ethernet thiab 2x400 Gigabit Ethernet. Cov lus cog tseg ntawm pheej yig dua serial txuas nyob rau hauv daim ntawv ntawm 400G-ZR yog thaum kawg yuav tsum tau paub.

Txij li feem ntau optical transceivers thiab active optical cables tau noj nyob rau hauv cov cheeb tsam hauv zos tes hauj lwm, nws tsuas ua rau kev txiav txim siab kom txo cov nyiaj siv ua haujlwm thiab ncaj qha txuas cov optics rau silicon ICs hauv cov fibers. Co-packaged optics nyob deb ntawm kev tsim khoom-npaj, tab sis los ntawm 2020, kev ua haujlwm tseem ceeb yuav tshwm sim tom qab qhov xwm txheej vim tias Ethernet kev lag luam hloov nws cov leeg kev ua haujlwm nrog rau kev txhim kho nyiaj txiag rau kev sib txuas lus kho qhov muag ncaj qha mus rau silicon tuag.

Kev loj hlob nyob rau hauv lub ntiaj teb no network muaj peev xwm nyob rau hauv tag nrho cov sectors muaj ib txwm tau tsav los ntawm ob yam tseem ceeb; ntxiv cov neeg siv thiab ntxiv cov ntawv thov tshiab. Thaum tus naj npawb ntawm cov neeg siv txuas ntxiv zuj zus, nws yog dwarfed los ntawm bandwidth xav tau tsav los ntawm cov ntawv thov tshiab uas thaum kawg yuav tsum tau siv cov thev naus laus zis tshiab kom tau raws li qhov xav tau. Ib qho xws li chav kawm ntawm daim ntawv thov uas yog tsav kev loj hlob exponential nyob rau hauv xyoo tas los no yog kev txawj ntse thiab kev kawm tshuab (ML), tshwj xeeb hauv kev sib sib zog nqus neural networks.

Kev xa tawm ML system muaj ob theem. Ua ntej, cov qauv neural network yuav tsum tau cob qhia siv cov ntaub ntawv qhia. Thaum cov qauv kev cob qhia pom tau tias muaj tseeb txaus, lawv raug xa mus rau cov cav tov, qhov kawg daim ntawv thov tuaj yeem siv cov qauv kev cob qhia los kwv yees (lossis "infer") cov txiaj ntsig tau muab faib rau cov ntaub ntawv sab nraud lossis cov lus nug..

Txhawm rau ua kom cov txheej txheem kev cob qhia ML, kev sib piv yog siv nrog ntau qhov kev cob qhia cais. Qhov no ua rau cov kev xav tau ntawm lub network nruj heev rau kev faib cov ntaub ntawv kev cob qhia ntawm cov nodes, nrog rau cov txheej txheem kev cob qhia tom ntej raws li qhov tsis sib xws ntawm cov nodes los txhim kho cov qauv raug. Thaum lub sij hawm inference, daim ntawv thov kawg hais txog kev rov qab cov txiaj ntsig sai kom txo qis latency pom rau tus neeg siv kawg, thiab yog li ntawd qis latency yog qhov tseem ceeb. Rau cov laj thawj no, txhua tus tswv lag luam loj loj tau tam sim no siv lawv tus kheej ML kho vajtse, thiab qee qhov muab huab ML ua qhov kev pabcuam rau cov neeg siv kawg. Kev sib tw ntawm cov kev pabcuam huab sib txawv ntawm ML yog yuam cov neeg ua haujlwm txuas ntxiv mus nqis peev hauv kev txhim kho kev lag luam hauv network kom muaj kev sib tw, uas nyob rau hauv lem yog tsav Ethernet zej zog los teb rau cov thev naus laus zis uas txhawb nqa cov kev xav tau bandwidth ntxiv nrog cov teeb meem ntawm kev tswj hwm lub zog thiab tus nqi profile.

Txawm li cas los xij, cov tshuab ML sab hauv no tsis muaj txiaj ntsig tshwj tsis yog tias cov ntaub ntawv tawm tswv yim tuaj yeem sau thiab xa mus rau inference cav los ua kev kwv yees. Cov cuab yeej siv xws li tsheb tsav tsheb, kev lag luam IoT thiab cov tsev ntse, chaw ua haujlwm thiab cov nroog siv ntau hom kev sib txuas ntawm cov thev naus laus zis, wireless (tus kheej hauv cheeb tsam nrog rau hauv cheeb tsam network lossis WiFi), xaim nrog rau kev siv fais fab dhau Ethernet technologies, thiab cellular. (LTE thiab 5G). Tag nrho cov thev naus laus zis no siv Ethernet ecosystem los tsim kom muaj txiaj ntsig zoo, muaj txiaj ntsig zoo sib xws.
