HOI I KA LA ANA ME KA 10MB/S ETHERNET - PETER JONES, ETHERNET ALLIANCE a me CISCO.
He paʻakikī paha ke manaʻoʻiʻo, akā ua lilo hou ʻo 10Mbps Ethernet i kumuhana kaulana loa i kā mākou ʻoihana. Nīnau mai ka poʻe iaʻu: "No ke aha mākou e hoʻi ai i ka makahiki 1980?" He pane maʻalahi, a no mākou i hana i ka ʻoihana i kēlā manawa, he pane maʻamau. I kēlā au, ma mua o ka lilo ʻana o Ethernet i nā wahi āpau, ua like ka pūnaewele me ke komohana ʻāhiu. Ua loaʻa i kēlā me kēia me kāna mau protocols, nā papa kino, nā mea hoʻohui, a me nā mea ʻē aʻe. Eia naʻe, ua hoʻokumu ʻo IT i ka pūʻulu kumu o nā ʻenehana i Ethernet, e hāʻawi ana i nā kamaʻilio maʻemaʻe no nā piliona kānaka.
ʻO Peter Jones, ʻenehana hanohano, Cisco
Ua ʻae ʻia ʻo 10 Mbps Single Pair Ethernet (10SPE) e ka IEEE i Nowemapa 2019, me ka hoʻohui ʻana i ʻelua mau kikoʻī papa kino hou e kākoʻo i ka ʻikepili a me ka mana ma luna o 1000 m o ke kaula keleawe ʻelua wili hoʻokahi, a me ka hoʻopili ʻana i nā loulou multi-link me 8 nodes ma luna o 25. m uwea. . Hoʻohālikelike kēia mau hiʻohiʻona no ka ʻae ʻana iā Ethernet i loko o nā hale a me nā ʻoihana ʻenehana. Hoʻokumu ʻia ka papahana Advanced Physical Layer (APL) ma 10SPE no nā noi wahi pilikia.
Ua hoʻomohala ʻia ʻo 10SPE e hoʻokō i nā pono o nā mea hoʻohana ma ke kahua o ke kūkulu ʻana i ka automation a me ka ʻenehana ʻoihana a maʻalahi a hoʻolōʻihi i ka hoʻololi ʻana i Ethernet. Hana kēia i ka hoʻohana ʻana i nā protocol network a me nā lawelawe i kahi pilikia maʻalahi e hoʻoponopono, e ʻae ana i ka honua OT e pōmaikaʻi mai 30 mau makahiki o ka hana hou ʻana o IT. Loaʻa i ka ʻoihana i kēia manawa ka manawa e kūkulu ai i hoʻokahi, ʻoihana pūnaewele maʻamau no nā lako.
Ke huli nei ʻo Ethernet i 40, hauʻoli wau i ka wikiwiki mai nā lā mua.

No nā ʻoihana ʻoihana, ʻoihana, automotive a me nā noi home, e ʻike mākou i ka hoʻonui ʻana i ka hana i ʻōlelo ʻia o Power over Ethernet (PoE) ʻoiai ua kākau ʻia nā koho PoE hou a lawe ʻia i ka mākeke no kahi ākea o nā noi a me nā ʻōnaehana hou - mai nā hale akamai a hiki i nā mea hana a me ka Pūnaewele o nā Mea, nā mea ʻike a me nā mana. No ka hōʻoia ʻana i nā huahana PoE i kūʻai ʻia e like me ka hoʻokō ʻana i kēia mau pae hana i hoʻāʻo ʻia e nā laboratories ʻaoʻao ʻekolu i hōʻoia ʻia, e ʻōwili ʻia ka Ethernet Alliance i ka pae aʻe o kāna papahana hōʻoia PoE. ʻO kekahi wahi ʻē aʻe o ka hoʻokomo wikiwiki ʻana i ka ʻenehana Ethernet hou i nā noi e hoʻopili i ko mākou mau home a me nā ʻoihana i ka ʻoihana koʻikoʻi ma o ka hoʻomohala ʻana i ka ʻenehana Passive Optical Network (PON), e hāʻawi i ka wikiwiki o 50 Gbps ma waena o nā pūnaewele. hiki aku ma kahi o 50 km.
E hele mai ana ka nui o ka ikepili Ethernet kiʻekiʻe i ka mākeke no ka hoʻokō ʻana i nā pono o nā noi wikiō hou i hiki ke loaʻa ma o nā ʻoihana kapua. No ka hoʻohālikelike ʻana i nā helu ʻikepili e like me 100 Gbps, 200 Gbps a me 400 Gbps, ke hoʻomohala nei nā mea ʻenehana i nā mea hou a me nā hale hana hou e hiki ai i kēia mau wikiwiki ke hele ma mua o ka mea hiki ʻole i ka wā ma mua. Ke hoʻohana nei i nā mea hana hoʻohālike ikaika a me ke kūkulu ʻana i ka ʻike i hala, akā me nā mea hou, e ʻike mākou i nā lako Ethernet, nā modula optical, nā mea hoʻohui a me nā kaula e hiki ai i nā mea hoʻohana kikowaena data hyperscale a i ʻole ke ao ke piʻi i nā pae hou o ka hana a hāʻawi i nā lawelawe hou.
ʻOiaʻiʻo, ʻaʻole ʻo 2020 wale nō ka makahiki IEEE 802.3 i 40, akā ʻo ka makahiki hoʻi o ka hoʻonui ʻana a me ka ulu ʻana i nā noi Ethernet e hiki mai ana, ka hana, a me nā helu data.

ʻO Jim Theodoras, Hope Pelekikena o ka noiʻi a me ka hoʻomohala ʻana, HG Genuine USA
Ma nā kikoʻī hou aku, ʻo 2020 kahi milestone hou no Ethernet me ka hoʻokomo ʻana i ka laina huahana 112 Gbps. ʻOiai ʻaʻole he mea hou ka 100 Gigabit Ethernet, ʻo ka loaʻa ʻana o kēia wikiwiki ma nā loulou serial ʻaʻole wale e hoʻolako i ke kolu o ka hanauna o nā huahana 100 Gigabit Ethernet i hoʻonui ʻia, akā hiki nō hoʻi i ka lua o ka hanauna o 400 Gigabit Ethernet a me ka 800 Gigabit Ethernet mua i kekona. I loko o ka Ethernet kaiaola, pono nā mea a pau e lele i mua e hana wikiwiki, ākea, a ma nā ʻano modulation paʻakikī. ʻO ka hanauna mua o 400-Gigabit client optical transceivers ma muli o 8x28Gbaud PAM4 e hoʻomaka i ka hoʻouna. Ma ka manawa like, e hōʻike ʻia nā mea kūʻai mua 800 Gigabit/s ma 8x100 Gigabit Ethernet a me 2x400 Gigabit Ethernet. ʻO ka ʻōlelo hoʻohiki o nā loulou serial liʻiliʻi ma ke ʻano o ka 400G-ZR ua kokoke e hoʻokō ʻia.
Ma muli o ka pau ʻana o ka hapa nui o nā transceivers optical a me nā kaula optical ikaika i nā ʻoihana kūloko, kūpono wale ke hoʻemi ʻana i luna a hoʻopili pololei i nā optics i nā IC silicon i loko o kēia mau fiber. ʻAʻole mamao loa nā optics co-packaged mai ka hoʻomākaukau ʻana, akā ma ka 2020, e hana ʻia nā hana koʻikoʻi ma hope o nā hiʻohiʻona i ka wā e hoʻololi ai ka ʻoihana Ethernet i kona ʻenehana loea a me nā kālā hoʻomohala i ka hoʻohui ʻana i nā kamaʻilio optical pololei i ka make silika.

ʻO ka ulu ʻana o ka hiki o ka pūnaewele puni honua ma nā ʻāpana āpau i alakaʻi ʻia e nā kumu nui ʻelua; hoʻohui i nā mea hoʻohana a hoʻohui i nā noi hou. ʻOiai ke hoʻomau nei ka nui o nā mea hoʻohana, ua liʻiliʻi ia e nā koi bandwidth i alakaʻi ʻia e nā noi hou e koi ai i ka hoʻohana ʻana i nā ʻenehana pūnaewele hou e hoʻokō i ka noi. ʻO kekahi o ia papa noi e hoʻoikaika nei i ka ulu nui i nā makahiki i hala iho nei, ʻo ia ka naʻauao artificial a me ke aʻo ʻana i ka mīkini (ML), ʻo ia hoʻi nā convolutional deep neural network.
ʻO Rob Stone, ʻenehana hanohano, Broadcom
No ka wikiwiki i ke kaʻina hoʻomaʻamaʻa ML, hoʻohana ʻia ka parallelization e pili ana i kekahi mau node aʻo ʻokoʻa. Loaʻa kēia i nā koi ʻoihana paʻa no ka puʻunaue ʻana i ka ʻikepili aʻo ma waena o nā nodes, a i ka wā o ke kaʻina aʻo hope e hoʻololi ʻia nā ʻāpana ma waena o nā nodes e hoʻomaikaʻi i ka pololei o ke kumu hoʻohālike. I ka wā o ka manaʻo, hoʻoikaika ka palapala hoʻopau i ka hoʻihoʻi koke ʻana i ka hopena e hōʻemi i ka latency i ʻike ʻia e ka mea hoʻohana hope, a no laila he mea koʻikoʻi ka latency haʻahaʻa. No kēia mau kumu, ua kau nā mea hoʻohana hyperscale nui i kā lākou lako ponoʻī ML, a hāʻawi kekahi i ke ao ML ma ke ʻano he lawelawe no nā noi mea hoʻohana hope. ʻO ka hoʻokūkū ma waena o nā lawelawe kapuaʻi ML ʻokoʻa ke koi nei i nā mea hoʻohana e hoʻomau i ka hoʻopukapuka ʻana i ka hoʻomaikaʻi ʻana i ka ʻoihana pūnaewele e hoʻomau i ka hoʻokūkū, ʻo ia hoʻi ke alakaʻi nei i ke kaiāulu Ethernet e pane i nā ʻenehana e kākoʻo ana i ka hoʻonui ʻana i nā koi bandwidth me nā pilikia o ka mālama ʻana i ka mana kūpono a me ke kumu kūʻai.
Eia naʻe, ʻaʻole pono kēia mau ʻōnaehana ML i loko ke ʻole hiki ke hōʻiliʻili ʻia ka ʻikepili hoʻokomo a hoʻouna ʻia i nā ʻenekini inference e hana i nā wānana. Hoʻohana nā mea like me nā kaʻa ʻokoʻa, IoT ʻenehana a me nā home akamai, nā keʻena a me nā kūlanakauhale i nā ʻenehana hoʻohui like ʻole, ka uila (nā ʻenehana wahi pilikino a me nā pūnaewele wahi kūloko a i ʻole WiFi), i hoʻohana ʻia me ka hoʻohana ʻana i nā ʻenehana Power over Ethernet, a me ke kelepona. (LTE a me 5G). Hoʻohana kēia mau ʻenehana āpau i ka kaiaola Ethernet no ka hana ʻana i nā hopena maikaʻi loa.
Ke lawelawe nei ʻo Nathan Tracy ma ka papa alakaʻi o ka Ethernet Alliance a ua komo ikaika ʻo ia i ka hui no nā makahiki i hala. He mea ʻenehana ʻo ia i ka hui System Architecture a me ka Industry Standards Lead for the Data and Devices business unit ma TE Connectivity, kuleana no ka hoʻomohala ʻana i nā maʻamau a me ka hana pū ʻana me nā mea kūʻai nui e hana i nā ʻōnaehana ʻōnaehana hou. He lālā ikaika ʻo Nathan no kekahi mau hui ʻoihana, e lawelawe ana i kēia manawa ma ke ʻano he Pelekikena a he lālā o ka Papa o OIF a ke hele mau nei a hāʻawi i ka IEEE 802.3 a me COBO.
He lālā ʻo Jim Theodoras o ka papa alakaʻi o Ethernet a me ka hope pelekikena o ka noiʻi a me ka hoʻomohala ʻana ma HG Genuine USA.

Loaʻa iā ia ma luna o 30 mau makahiki o ka ʻike ma ka ʻoihana uila a me ka ʻoihana optics, e uhi ana i kahi ākea o nā kumuhana like ʻole. ʻO Jim ka pelekikena mua o ka Ethernet Alliance a me ka mea hoʻoponopono kamaʻilio optical mua no IEEE Communications Magazine. Loaʻa iā ia nā patent 20 ma ke kahua kelepona a he mea hāʻawi pinepine i nā paʻi ʻoihana.
ʻO Rob Stone, ka Papa Hoʻokele ʻo Ethernet Alliance, he ʻenekini hanohano ma ka hui ʻo Switch Architecture o Broadcom, ʻoihana loea i nā kikowaena kikowaena data, protocol a me ka hoʻolālā awa. He mea komo ikaika ʻo ia i kekahi mau hui ʻoihana, me ka IEEE 802.3, COBO a me nā modula MSA ʻē aʻe, a ua alakaʻi ʻo ia i ka MSA RCx a me 25G Ethernet Technical Working Group. Ua ʻoi aku ʻo Rob ma mua o 18 mau makahiki o ka ʻoihana e lawe mai i ka ʻenehana kamaʻilio i ka mākeke.
