Iyo Spanning protocol protocol, dzimwe nguva ingotaurwa seyenzeri yemuti, ndiyo iwe kana mapquest yemazuva ano ethernet network, nzira yepamoyo yakanyanya kunaka zvichienderana nemamiriro ezvinhu chaiwo.
Zvichienderana neAlgorithm yakagadzirwa neAmerican Computer Scientist Radia Perlman painenge ichishandira muti weDhijitari (Dec) muLitting Yokudzima maChinakanidza uye kutevedza nzira dzekutaurirana mune dzakaomarara network. Sechikamu chechipiri, muti wekupfura unogona nzira dzekutenderera dzakatenderedza matambudziko ekutangisa kuti uone kuti kutaurirana kunokwanisa kumhepo kuburikidza network inogona kunge ichisangana nezvakaipa.
Spanning Tree topology vs. mhete topology
Masangano paakangotanga kusevha makomputa avo muma1980, imwe yeiyo gadziriro yakanyanya kuzivikanwa yaive iyo mhete network. Semuenzaniso, IBM yakaunza chiratidzo charo chepfungwa chekureva mhete muna 1985.
Mune ring network network topology, imwe neimwe node inobatanidza nevamwe vaviri, iyo inogara pamberi payo pane mhete uye imwe yakamiswa kumashure kwayo. Zvikwangwani zvinongofamba zvakatenderedza chindori mune imwe nzira, ine imwe neimwe node munzira yekubvisa chero uye mackets ese akatenderedza kutenderedza rin'i.
Ndichiri nyore mhete network inoshanda zvakanaka kana paine mashoma emakomputa, mhete dzinova zvisina kukodzera kana mazana kana zviuru zvemidziyo zvinowedzerwa kune network. Komputa ingangoda kutumira mapaketi kuburikidza nemazana emamapepa ekungogovana ruzivo neimwe imwe system mune yepedyo imba. Bandwidth uye kuendesa zvakare dambudziko apo traffic kana traffic chete inogona kuyerera nenzira imwe, pasina chirongwa chekudzosera kumashure kana node munzira ichipunzika kana kunyorwa.
Muma 90s, seEthnet akawana nekukurumidza (100Mmbit / sec. Mhete yakakurumidza kupera.
Mashandiro emuti anoshanda sei
Spanning Muti ndiko kuendesa protocol ye data mapaketi. Ndiwo chikamu chimwe chikamu chekutevera cop uye chikamu chimwe chete cheinjiniya yemijiniya yemigwagwa yenzvimbo iyo data inofamba kuburikidza. Iyo inogara paLayer 2 (Data Blank Layer), saka inongova neyekufambisa mapaketi ekuenda kune yavo yekuenda, kwete mhando yemapaketi adzorerwa, kana iyo data yavari.
Spanning Muti watove wakadaro ubiquitous kuti kushandiswa kwayo kunotsanangurwa muIeee 802.1d Networking Standard. Sezvinotsanangurwa muyero, imwe chete inoshanda nzira inogona kuvapo pakati pemamwe maviri endpoints kana zviteshi kuitira kuti vazive nemazvo.
Miti Yakatarwa Yakagadzirirwa Kubvisa mukana wekuti data iri kupfuura pakati pematareji emakonzo ichabatirira mune chiuno. Muzhinji, loops inovhiringidza iyo Algorithm algorithm yakaiswa mumidziyo yeNetwork, ichiita kuti chishandiso chichazomboziva kuti kutumira kupi kutumira mapaketi. Izvi zvinogona kuguma nekudzokorora kwemapuranga kana kuendesa kwekudzokorora mapaketi kune dzakawanda dzekuenda. Mameseji anogona kudzokororwa. Kukurukurirana kunogona kusvetukira kumashure kune anotumira. Inogona kunyange kupaza network kana zvakawandisa zvishwe zvinotanga kuitika, kudya bandwidth pasina chero mukana wekutadza uchizadza imwe isina kutaridzika traffic kubva mukufamba.
Iyo yekupfura protocol protocolinomira zvishwe kubva pakugadziraNekuvhara zvese asi imwe nzira inogona kuitika kune imwe neimwe data packet. Switches pane network shandisa muti wekunyepedzera kuti utsanangure midzi nzira uye mabhiriji uko data inogona kufamba, uye inovhara iyo isingashande uye isingagoneki nepo nzira yekutanga iripo.
Mhedzisiro yacho ndeyekuti kutaurirana network kunoyerera kusanzwisisiki zvisinei nekuti yakakura sei kana yakakura network inova. Nenzira, muti unopfeka unogadzira nzira imwechete kuburikidza network yedata kuti ifambe uchishandisa software imwe chete iyo mainjiniya akashandisa marefu pane yekare loop network.
Kuwedzera Kubatsirwa kweMuti Wekutanga
Chikonzero chekutanga chechikutuka muti unoshandiswa kubvisa mukana wekutora zvishwe mukati me network. Asi pane zvimwe zvakanakira zvakare.
Nekuti muti unopfeka uchigara uchitsvaga uye uchitsanangura ndedzipi nzira dzekutengesa dziripo dzemapaketi ekufamba-famba, zvinogona kuwona kana node yakagara pamwe neimwe yeiyo nzira dzekutanga dzakaremara. Izvi zvinogona kuitika nekuda kwezvikonzero zvakasiyana siyana zvinobva pakutadza kweHardware kune iyo itsva network yekugadziriswa. Inogona kunyange kuve mamiriro enguva pfupi zvichienderana neBandwidth kana zvimwe zvinhu.
Kana miti yekupfura ichiona iyo nzira yekutanga haisisiri kushanda, inogona kukurumidza kuvhura imwe nzira yaive yakambovharwa. Inogona kuendesa data yakatenderedza nzvimbo yenhamo, pakupedzisira ichisarudza iyo detour seye mutsva wekutanga nzira, kana kutumira mapaketi kumashure kune yekutanga bhiriji inofanira kuwanikwa zvakare.
Nepo iyo yekutanga spanning muti nekukurumidza mukukasira mukukanganisika kuti zvibvumirano zvitsva sezvazvinodiwa, muna 2001 Theeee vakaunza iyo yekukurumidza kupunzika muti protocol (rstp). Zvakare zvinonzi 8802.1W vhesi ye protocol, rstp yakagadzirirwa kupa zvakanyanya kupora nekukurumidza mukupindura network shanduko, kutadza kwenguva pfupi kana kutadza chaiko kwezvinhu.
Uye nepo RSSSTP iyo nzira nyowani convergence maitiro uye Bridge port zvimiti zvekusimudzira maitiro, zvakagadzirirwawo kuve zvakazara zvidzoreredzo zvinoenderana nemuti wekutanga wekupfura. Saka zvinokwanisika kuti zvishandiso zvine shanduro mbiri dzeProtocol kuti ishandire pamwe chete pane imwe network.
Kupfupika kwemuti wekupfura
Nepo miti yakatanga ichinge yava ubiquitic pamusoro pemakore mazhinji ichitevera sumo, kune avo vanopokana kuti ndizvonguva yasvika. Chipo chikuru chemuti wekupfura ndewekuti unobvisa zvishwe zvisingagoneki mukati me network nekuvhara pasi nzira dzinogona kufamba. Mune chero netiweki yakapihwa uchishandisa muti wekupfura, anenge 40% yenzira dzinogona kuvharwa kune data.
Mune zvakanyanyisa kuomarara nharaunda, senge izvo zvinowanikwa mukati me data nzvimbo, kugona kukwira nekukurumidza kusangana nechikumbiro chakanyanya kuderera. Pasina zviyero zvakaiswa nemuti wekupfura, nzvimbo dze data dzinogona kuvhura yakawanda bandwidth isina kudiwa kwekuwedzera networking hardware. Urwu ndirwo rudzi rwemamiriro ekunze, nekuti nzvimbo dzakaomarara network ndedzipi nzira dzinotenderera dzakagadzirwa. Uye zvino chidziviriro chakapihwa ne protocol prothing looping iri, nenzira, akabata nharaunda idzodzo kubva pakukwanisa kwavo kuzere.
Shanduro yakanatswa yeiyo protocol inonzi Muenzaniso Muenzaniso Muenzaniso (MSTP) yakagadziriswa kuti ishandise nzira dzeViramba uye righese Nzira dzeNetwork kuti dziwedzere panguva imwe chete, uchiri kudzivirira zvishwe kuti uzviumbire. Asi kunyangwe neyeMSTP, mashoma mashoma maitiro maitiro anoramba akavharwa pane chero yakapihwa network uchishandisa iyo protocol.
Pave paine akawanda asina-akaenzana, akazvimiririra kuedza kuvandudza kurambidzwa kweBandwidth yemuti wekupfura mumakore apfuura. Ivo vagadziri vevamwe vavo vakati kubudirira mune yavo yekuedza, vazhinji havana kunyatsoenderana neyekuita protocol, masangano anofanirwa kushandisa shanduko dzisina kujairika pane zvese zvishandiso zvadzo kana kuwana imwe nzira yekuvatendera kuvapo Switch inomhanya yakajairwa stranningt muti. Muzhinji, mitengo yekuchengetedza uye kutsigira magetsi mazhinji emuti wekupfura haana kukodzera kuedza.
Muti unopfura ucharamba uri mune ramangwana here?
Kunze kweinogumira muBandwidth nekuda kwekutanga kwekuvhara nzira yekuvhara nzira nzira, hapana pfungwa yakawanda kana kushanda nesimba kuiswa kutsiva iyo protocol. Kunyangwe ieee dzimwe nguva kuburitsa zvinyorwa kuti uedze uye kuita kuti zvinyatsobudirira, zvinogara zvichisimba zvichikosheswa nemhando dziripo dze protocol.
Mupfungwa yakati, muti unopotera unotevera mutemo we "kana usina kutyorwa, usazvigadzirisa." Spanning Muti wakazvimirira kumashure kwemashure ekumashure kuti uchengetedze traffic kuyerera, uye kufambisa traffic zvakapoteredzwa kuti vashandisi vamboziva kana nzvimbo yavo yekoneti yekuvhiringidza kwenguva pfupi seyakaenzana neyakaenzana. Mashandiro ezuva. Zvichakadaro, pane iyo backend, maneja anogona kuwedzera midziyo mitsva kune yavo network ndisina kufunga nezve kana kuti kwete kuti ivo vachakwanisa kutaurirana nedzimwe network kana nyika yekunze.
Nekuda kwezvose izvo, zvinogona kuti muti wekutanga unoramba uchishandiswa kwemakore mazhinji kuti uuye. Panogona kunge paine zvidiki zvidiki nguva nenguva, asi iyo yepakati protocol protocol uye zvese zvezvinhu zvinorema zvinoita kuti zvingangove pano kuti ugare pano.
