ukuhlanganisa isitchi

Ukuhlanza kwezikhithi kuchaza ukusebenzisa izikhithi ezimbili noma ngaphezulu njengokunye okulungile. Lokhu kuvumela abasebenzisi ukuphatha izikhithi ngokunye ngokusebenzisa umkhiqizo ohlangene, okwenza ukuphathwa kwekhilomu kude kusemthetheni futhi ukuhleke kakhulu. Kule nkqubo, izikhithi zihlotshaniswa ngokuhlangana nokusetshenziswa kwamapothi noma amakhebula ehlobene, ukudala umugqa olula neyodwa. Incamelo ishukuma ekhethe isikhithi esisodwa ukuba yinkosi, eyona ontrola yonke into kanye nokuxhumana phakathi kwazo zonke izikhithi. Teknolojhi le ihlinzekisa izinhloso ezifanayo ezijwayelekile, ukubuyekeza okuzenzekelayo komlilo, futhi ukusebenza ngendlela ethintekayo. Ukuhlanza kwezikhithi kuvumela ukusebenzisa kakhulu kanye nokuthuthukiswa kwekhilomu, ukunikeza ukuthuthukiswa kusuku kuya phezulu kwezikhithi ezimbili kuya phezulu kwezinye izinhlobo. Teknolojhi le isebenza ngemindleko evelayo yokwahlula indawo neyodwa, ukuyigcina ukusebenza kakhulu kwekhilomu. Nenxenye yezinhloso ezinjengo- cross-stack link aggregation kunoma iyiphi engaphandle yezinhloso (QoS) teknolojhi le ihlinzekisa ukuxazululo ngokuphelele kwekhilomu yesikhathi samanje.

Ukusebenza kwezityekisi kunezimboniso eziningi ezingcono ezingaba yindlela esingcono dlayo kweqile ukusebenza kwamanethiwekhi edlule. Okokuqala, kwenza ukusebenzelwa komkhankaso ngokuphelele ngeke abasebenzisi bakwazi ukuseta nokulandela izityekisi ezimbini njengenyani efanayo, lokhu kwenza ukusebenza okuncane nezikhathi ezidingekayo. Le ndlela yokuphathwa kwenza ukuthi kube khona ukusebenzisa amanethiwekhi futhi amasethingi aphumelelwe ngokugcwele kuwo wonke ama-unity ezityekiswayo ngasese. Le theknoloji ikunentetho yokuthi kunezifanekelo eziphambene nezifanekelo zokusebenza ngokuzenzakalelayo, lokhu kwenza ukuthi manethiwekhi isebenze ngaphansi kokusebenza kahle noma lapho i-izityekisi ezimbili lihlathekile. Ngenxa yokuthi kungaphelekiwe, ukusebenza kwezityekisi kunika amakhiyamo ukuthi abasebenzisi bakwazi ukwanda kwekapasithi yamanethiwekhi ngokwengeza izityekisi ezintsha kwi-stack noma kungenzeka ukuthi kubekwe amagugu amakhulu. Le sithemba inkxenye yezifano ezininzi ezineshadi elisha, njengokuthi kuhlanganise amanye amakhona, lokhu kwenza ukuthi kube khona ukuthuthukiswa kwe-bandwidth futhi kunebanga lokusebenza okuningi lapho manethiwekhi isebenze. Ukothmele kwezimali kunye nendlela enconele kakhulu, ngenxa yokuthi ukusebenza kwezityekisi kungena inkinobodlo lekuthi kudingeka ukuphatha amanyongo alandelwayo futhi kungena inkinobodlo lekuthi kudingeka ukubalwa kwe-IP addresses oluningi lapho kusebenzwa umkhankaso wamanethiwekhi. Le theknoloji ikunentetho yokuthi kungcono ukulungisa imiphatlalo futhi kusebenze ngokushesha, ngenxa yokuthi abasebenzisi bakwazi ukuthola futhi ukulungisa imiphatlalo ephansi kwezinye zonke izityekisi ezityekiswayo kusukela ekwakheni elilodwa lokuphatha. Ngokudla, ukusebenza kwezityekisi kunikela amagatshana amaningi asetshenziswa kakhulu futhi akunika amagama okuthi kusetshenziselwa ngokulinganisa kuwo wonke ama-unity ezityekiswayo, lokhu kwenza ukuthi kube khona ukusebenza kwe-manethiwekhi futhi kunebonga lokuthi kusetshenziselwa ngokulinganisa.

Ukuphathwa nokukhawuleza okuhlangene

Ukubeka amaphoyinti ngokwesikweletu kwenza uhlangano lwemibandela ngekusebenzisa imininingo yokuqasha ngokunye. Le ndawo ibindlela amaphoyinti angaphezu kweyodwa ngumuntu oyisilungu, kulokho kube kuvumela abasebenzisi ukwenza iziguquko ezikulokothi, ukuvuselela nokugcina amavisiso ngokudala isandiso esisodwa. Imithambo ivumele ukusanibonakalayo okuphephile kuzo zonke izinyathelo eziphileni, ukuze kuhlanjelwe ukusebenzela izimiso neempilo zokusebenza kuzo konke indawo. Le ndlela yokuxhasa ngokunye ikancise inzima nezindlela ondinga ukwenza ukulungiswa nokulungisa izinkinga. Iphoyinti evelayo iyaziwa ngokuzenzekelayo ukuguqula izinto ezikulokothi kuzo zonke amagumbi aphindele, ukuthiwa akudingeki ukuguqula ngokwayebhale kwezinye iziphoyinti futhi ukunciphisa amathiphu afaiswa abantu. Le mininingo yokuphepha ngokudala isandiso kuyinhloso ngokukodwa endabeni elikhulu lomkhombandlela lapho kudingeka ukube nemigomo ehambisana nezinye iindlevo ukulethu emsakeni wefomu futhi ukujikeleza.

Ukubaluleka Okuphakathiweyo kunye nokudityaniswa

Izixhobo zokudityaniswa ezifakwe kwiqondo lokugcina le-switching zinika inkqubo yonikezelo eliphezulu kunye nokulawula isicelo. Inkqubo iyasebenzisa i-mechanism efanayo yokuguqulela indawo ngokuzenzekelayo apho intambo ye-stack ingenelanga ngeengxaki. Le mekanismi efanelekileyo yokuguqulela indawo inika inkqubo yokusebenza ngaphandle kokuchithwa, even if there is hardware failure or maintenance activities. I-stack iyahlala inquma ezininzi zedatha ebalulekileyo phakathi kweenkqubo ezahlukeneyo, zinika ukuphela kwe data kunye nokukhupha ngokushesha. Ngokonge, lo technology uwukwazi wezivumo ezahlukeneyo zokudityaniswa kunye nezixhobo zokwahlula ubunzima obuqhelekileyo apho bahlula indawo yokusebenza ngokuhambelana nezindlela zazo zizonke, ukuvelisa iperfomansi kunye nokuvimba izindawo eziphambene. Lo qhawekayo wokubaluleka lwenkqubo inyathelo elidekileyo kwiimeko eziphethekileyo zonikezelo apho ikhomshi ayikwazi ukungena.

Ukukhula kwaye ukuyahlula ngokuzenzekelayo

Ukubeka amaswithi kungenhla ukuvutha okukhulu kwemibandela yokuthutha engqondweni ukuthutha ngezimali zokuthutha. Le teknoloji ikhipha ukudibanisa amaswithi amasha emsindeni, kuvumela ukuthutha ngokwengeza engqondweni yasele ithinte imisebenzi yayo. Le mibandela yokuthutha ivumela izinkampani ukuthi qale ngendawo encane kanye nokuthutha njengoba kubekezelwe, kuvuma ukuthutha okunemali. Teknoloji yokubeka amaswithi emsindeni nakho ikhipha imibandela ephambene eyona ngokuhamba kwesikhathi, iqukethe inkqubo yokuphatha ubude bendawo bokuxhumana ne-routing yokulayisha iqhaza, kunezindlela zokugcina ukuthi le ndawo iyasebenza ngokushesha. Ukuvikela phambi kwesikhathi kuvumelwa ngokuthutha ngezimali ezintsha ze-intanethi, kuvuma ukuthi le ndawo ibe yasekelwe kanye nokuthi inake ukuthutha okunguqukthe ngokushesha. Inhloso yokuthi usebenzisa amamodeli we-switch angalingani endabeni elijwayelekileyo avumela ukuthola ukuguqula kanye nokuphila kwe-engqondweni yasele.
