iswitshi se-intanethi yefayibha

Isithungisi se-intanethi yasephetho sisebenza njengesikhombisi esibalulekile sokuxhumana okungenisela ukuthunyelwa nokuphatha kwezinhlangano zokuxhumana ezintathelene nezepetho. Le theknolojhi elibangelweni isebenza njengenqanawe entsha, ekuvumeleni ukuthunyelwa okulula kwedatha phakathi kwezilima eziningi ngemuva nokuphepha isendvolo esiphakeme kanye nesekhudzu esingcono esinazo izepetho. Le theknolojhi inezinto ezahlukene ezifana ne-suporta ye-VLAN, ukuphatha ubungo bendawo (QoS), nezindlela zokuhlanganisa amaporti, ekugciniselwa kubona kube lula ukusebenza kwenethiwekhi. Izithungisi zamanje ze-intanethi yasephetho zinesendvolo ekuhlaleni kusukela ku-1Gbps usuku ku-100Gbps, lokhu kuvumela ukuthi kusetshenziswe yisemakhaya kunoma kusemozweni. Lezi zikhombisi zinezimali zase-SFP ezivumela ukusetshenziswa kwezinhlobo eziningi zezithungisi sephetho, ekuvumela ukuthi ikhwekhwelethwa lenethiwekhi libe lula ukongena. Isistimu yokuphatha intshitshi yesithungisi iyabonga amaphethini edatha, ekuchazeni ukuthintana kwenethiwekhi futhi ekuphepheni isendvolo esijwayelekile phezu kwoxhumano onke. Ngaphezulu, izinhlobo ezingu-nga-ma model zinamathuluzi amakhubalo angempela, afakele ukuphepha kwezimali, uhlelo lokondisa ukufinyelela, nokuphepha umoya, ekugcineni lenethiwekhi leso kufa nokufinyelelwa akuvumelekile kanye nezindleko ezinjalo.

Imigcina ye-fiber internet inikeza amatholiso amaningi okwenza yena engavunyelwe kuzo zokuxhumana ngemisebenzi yam today. Okokuqala, aza nika amaspeedi nama-bandwidth amakhulu, ekuvumela abasebenzisa ukuthumela amathatha amakhulu wodatha ngaphansi komehluko. Imigcina le-fiber enemaphasi amancane ekuxhumeni asimise amathimele aphakeme kuzo zokusebenza ngokushesha, njengokubhejwa kovidiyo, ukudlala kwezinethi, nokusebenzisa izinkundla zasekhaya. Lezi mgcina uyahlula ukugcinwa kweyisalyo (signal integrity) phakade emakathini amade, okwenza yena ngokwehlisa ukusebenziswa kwezinethi ezikhulu kuzo zonke izindawo. Imigcina le-fiber enezinhlobo zokubuyela futhi inezinto ongavuselela ukuthi izinethi zingasekudliwe, ekuvumela ukuthi izinkampani zisebenze ngokuvamile. Ukusebenzisa amandla amancane yinto ehlukene, ngoba lezi mgcina isebenza ngamandla amancane ukulingana nezifakwe ngemali edlule ngaphandle kokunikeza iziphumo ezinhle. Le mgcina ikhuthaza ukwahlukaniswa kwezinethi, ekuvumela ukulayisha izindlela nezokuphepha ngokuvamile ngokwahlukanisa izinethi ezikhoyo. Ukuthambeka kwayo kuzo zonke izinethi eziphakelwe kudala kwenza ukuthi ukusebenzisa kudala kube lula, futhi ukuthambeka kwayo kuzo zonke izinto ezingenakudliwa kuvumela ukuthi kubekwe ngaphezulu. Imigcina le-fiber inezinhlobo zokuphatha izinethi ezikhulu, ezinikeza amatholiso amaningi kuzo zonke izinto ezingenakudliwa, ekuvumela ukuphathwa kwezinethi kude kakhulu. Futhi, lezi mgcina inikeza ukuvikela kakhulu kuma-interference amagijelelekithi, okwenza yena ukuthi kube yimali kuzo zonke izimo ezinezinga eliphezulu lomoya.

Inkampani yokuphatha intonga

Inkampani yokuphatha intonga enobuhle obukhulu esitimbeni se-intanethi iswitch yasekhethi ibonisa ukuthuthuka kwe-optimization wenkqubo. Le nkampani isebenzisa amathithi amathini ukuze analise futhuza izinhlobo zedatha ngokushesha, uyinikezela ukuthi izisebenziso eziphambene ngebandwidth bese kuyimelwe inkqubo yonke yenkqubo iyilapha. Isakhiwo sokugcina okuningi kuvumela ukusebenza ngokwesibonelo datha eziningi ngokulandelana, kubangela ubuncinciso obukhulu lokuqala futhuza amaphuzu. Inqubo inezinto ezibalulekile ezingavunyelwa ukwakhiwa ngokwemigomo yesikrini, kuvumela abasebenzisi ukuthayelela izisebenziso eziphambene ngaphezulu kwalezi ezifanele. Le nkampani yokuphatha amathini nezindlela zokukhombisa ezinezinkinga ezinhle, ezinikezela imbono encane ngendawo yokusebenza yenkqubo, kuvumela ukwenza amakheli phambi kokungcola nokuxazulula izinkinga ngokushesha.

Inkampani yokuphepha enhlukaneneyo

Isithuthi seyisekwe ngekephupheni le fiber internet switches esematheni kuyindlela ezinhlanu ukulungiselela kakhulu ngokuxhumana nokwenene. Le ndlela enkulu yeseyikhi ihlanganisa izimo eziphambili njengo-802.1X authentication, MAC address filtering, ne-port security, okwenzela ngokwehlisa ukufinyelela okungalungileyo. Isicelo se-storm control senzelwa ukulungisa i-broadcast, i-multicast, nezinye i-unknown unicast storms engenakho ukugcina isethi yekhowudi. Ngokongezwe, le sithuthi seyisekwe inikeza inkxubelo ye-private VLAN, ekuvumela ukwahlukaniswa kwekhodi nokuhlukahluka komlando oqukethwe. Lo mbhalo ongeneza nezimiso zokuphepha ezihlangothini, ekunikeza ukusebenza okusekwe kwi-switch ngokujwayele. Izibuyekezo ezingcono zenkulandlela ziphethe iseyikhi xa kuhlanga nezixhobo ezingcono.

Ukuqokelela Kwesivumelwano Sokwandisa

Ukucwangcwa okuthuthukisa kwezithombe zokuxhumana se-fiber internet kuyindlela ethulwa phambili yokwenza umphakathi wenethiwekhi. Le ndlela yokudizayini incwadi yezinto ezitholakalayo nezokuthuthukiswa okungenkulungelo kubonelela ukuthuthuka ngendlela elula ngenkathi ithuthukisa inkampani. Ukucwangcwa kusekela izinhlobo ezahlukene zepholthi nezilava, kulolu balela ukuthuthukiswa ngokuzuzwe engenza ukuthi kufanele kube khona isisindo esikhulu sokuguqula sonke esifanekiso. Inkcukacha yokuphatha i-stack iyivumela amathitha angama-eshiya ukusebenza njengesiqephu esodwa, leyo edlula ukuchazwa futhi ikhulisa indawo yenethiwekhi. Le ndawo yokuthuthukiswa incwadi isekela inkxwelo ezahlukene zezixhumi zokuxhumana, kusukela e-single-mode kuze kwa-multi-mode fiber, ibonelela ukuthuthuka okuhlukahlukene kwamanexha. Ukucwangcwa kancane ukunemba okulula kwezinye iziphakamiso zenethiwekhi futhi kusekela ukuthuthuka komnikelo ongenele.
