Facebook's Terragraph tekinoroji inofamba kubva kumiyedzo kuenda pakushandiswa kwekutengesa

Seti yezvirongwa inobvumira mapoka ezviteshi zvidiki zvisina waya anoshanda pa60 GHz frequency kutaurirana.

Wireless World: Technicians muMikebud, Hungary vanoisa zviteshi zvidiki zveTerragraph kuti zviedze zvakatanga muna Chivabvu 2018.

Facebook yapedza makore ichigadzira tekinoroji yekuvandudza kurongeka kwedata uye kutapurirana kwayo pamhepo isina waya. Iyi tekinoroji yave kubatanidzwa mune inotengeswa diki fomati 60 GHz base zviteshi. Uye kana vanopa telecom vanobatanidzwa, zvinogona kubatsira nekukurumidza kubatanidza dzimba nemabhizinesi pasi rese zvisina waya kuInternet.

Tekinoroji yeFacebook, inodaidzwa kuti Terragraph, inobvumira zviteshi zvepasi kuti zviunganidzwe pamwechete, kuendesa ku60 GHz uye kuzvitonga nekuzvitonga uye kugovera traffic pakati pavo. Kana imwe base station ikamira kushanda, imwe ipapo inotora mabasa ayo - uye vanogona kushanda pamwechete kutsvaga nzira inoshanda kwazvo yekuti ruzivo rwupfuure.

Vatova vagadziri vemidziyo vakati wandei, kusanganisira Cambium Networks, Common Networks, Nokia и Qualcomm, yakabvuma kugadzira michina yekutengeserana inobatanidza Terragraph. Mharidzo yaro ichangoburwa yakaitika muna Kukadzi pakuratidzira kwekutengeserana MWC muBarcelona. Kana tekinoroji ichigona kushanda sezvakarongwa, Terragraph ichaita kuti Internet isvike nekukurumidza uye nekuchipa munzvimbo dzekutumirwa.

Zvichiwedzera, Broadband Internet, yakambogoverwa pamusoro petambo dzefiber-optic dzinodhura dzakavigwa muvhu, iri kuuya kudzimba nemabhizinesi pamusoro pemhepo. Kuti uite izvi, vatakuri vari kutarisa mabhendi e-high-frequency, ayo ane bandwidth yakakwirira kupfuura iyo yakabatikana yakaderera mafrequency ayo akashandiswa kwenguva refu kumagetsi evatengi.

Facebook inofarira V-bhendi, iyo inowanzodaidzwa kungoti 60 GHz, kunyangwe kutaura kwehunyanzvi inotambanudza kubva pa40 kusvika 75 GHz. Munyika dzakawanda haigarwi nemunhu, zvinoreva kuti yakasununguka kushandisa.

Kunyangwe midziyo yemukati inotsigira 60 GHz seimwe nzira yeWiFi yave iripo kwenguva yakareba, zviteshi zvekunze zvave kungoonekwa. MaISP mazhinji ari kufunga nezve kushandisa 60 GHz kuvhara mukaha pakati pezvivakwa zviripo nenzvimbo nyowani dzavanoda kusvika, kana kuwedzera huwandu hwenzvimbo dzakavharwa kare.

“Zvinonakidza zvechokwadi,” anodaro Shwetank Kumar Saha, shamwari yekutsvagisa uye mukwikwidzi wePhD mune sainzi yekombuta paYunivhesiti kuBuffalo (New York), kudzidza kushanda zvakanaka kwe60 GHz mutengi wemidziyo yekuisa mukati memba. -Vanhu vazhinji vasangana nematambudziko nekutengesa kwe60 GHz. Paive nehurukuro dzakawanda pamusoro penyaya iyi. "

Rimwe dambudziko nderekuti mamillimeter wavelength masiginecha (30 kusvika 300 GHz) haafambe kusvika pazasi masaini masiginecha, anotorwa nyore nemvura nemashizha, uye haapindi mumadziro nemahwindo.

Kuti utenderere matambudziko aya, vanopa vanowanzo shandisa yakagadziriswa isina waya network, umo zviteshi zvepasi zvinotumira chiratidzo kune yakagadziriswa inogamuchira iri kunze kwechivako. Uye kubva ipapo iyo data yatoenda kuburikidza neEthernet tambo.

Gore rakapera, Facebook yakabatana nayo Deutsche Telekom kuyedza iyo Terragraph system mumisha miviri yeHungary. Mumuedzo wekutanga ma technicians akabatanidza dzimba 100 kune network. Terragraph yakabvumira vagari kushandisa Indaneti paavhareji yekumhanya ye500 Mbps, panzvimbo ye5-10 Mbps yakagamuchirwa kuburikidza neDSL. Facebook parizvino iri kupedza miedzo nevashandisi muBrazil, Greece, Hungary, Indonesia, Malaysia neUnited States.

Iyo tekinoroji ine seti yesoftware yakavakirwa pa IEEE 802.11ay, uye inosanganisira zvinhu zvakaita sekupatsanura nguva kwakawanda kuwana, iyo inokamura chiteshi kuita nguva panguva iyo mabhesi akasiyana anogona kutumira masaini nekukurumidza kutevedzana. Muchikamu chinomwe OSI network modhi Terragraph inoshanda padanho rechitatu, ichipfuura ruzivo pakati pekero dzeIP.

MuTerragraph system, Facebook yakatora ruzivo rwayo kuendesa data pamusoro peiyo fiber optic chiteshi ndokuishandisa kune isina waya network, anodaro. Chetan Hebbala, Senior Director kuCambium. Iyo purojekiti yakauya yakazara denderedzwa muna 2017 apo Facebook yakagadzira iyo yakadzika routing software yemahara. Chirongwa ichi, Vhura/R, pakutanga yaiitirwa Terragraph, asi iko zvino yave kushandiswa kuendesa ruzivo pakati pe Facebook data centers.

Tekinoroji ichine miganhu yayo. Imwe neimwe base station inogona kufambisa chiratidzo pamusoro pechinhambwe chinosvika 250 m, uye kutapurirana kwese kunofanirwa kuitwa pamutsetse wekuona usinga dziviswa nemashizha, madziro kana zvimwe zvipingamupinyi. Anuj Madan, maneja wechigadzirwa paFacebook, anoti kambani yakaedza Terragraph mumvura nemuchando, uye kuti mamiriro ekunze "haasati aunza dambudziko" pakumhanya kwekuita. Asi Hebbala inotaura kuti, kana zvikaitika, dzakawanda 60 GHz zviteshi zvakagadzirirwa kushandura kwenguva pfupi kune yakajairwa WiFi frequency ye5 GHz kana 2,4 GHz kana kurasikirwa kukaitika.

Mutauriri weSprint akati kambani inoronga kuyedza Terragraph michina uye iri kutarisa nyaya dzine chekuita ne60 GHz spectrum kune network yayo. Mutauriri weAT&T akati kambani iyi iri kuita bvunzo dzemurabhoritari dze60 GHz frequency, asi haina hurongwa hwekusanganisira iyi nhanho mumatanho ayo aripo.

Saha, paYunivhesiti kuBuffalo, ane tarisiro pamusoro pemikana yeTerragraph yekubuda munyika. "Pakupera kwezuva, makambani achatarisa mutengo wehunyanzvi, uye kana iri shoma pane fiber, ivo vanozoishandisa," anodaro.

Hebbala anoti kambani yake yekutanga Terragraph-enabled base station parizvino iri mu "budiriro uye dhizaini chikamu" uye ingangosvika gare gare gore rino. Chinangwa chekambani ndechekupa Terragraph senge software iri nyore kugonesa kana kugadzirisa zvakare kure. "Ndinovimba, kana tataura mumwedzi mitanhatu, ndichakwanisa kutaura nezvevatyairi vendege uye kuyedza kutumira nevatengi vekutanga," anodaro.
