I-CF FIBERLINK Imikhiqizo yochungechunge lokushintsha kwezimboni yethule amamodeli wemikhiqizo angaphezu kuka-60, ngesikhathi esifanayo ocwaningweni oluqhubekayo nokuthuthukiswa kanye nokwandiswa kwesikali somugqa womkhiqizo. I-CF FIBERLINK I-Industrial switch yamukela izingxenye ze-industrial-grade kanye ne-hardware design, ukufakwa kwe-rack yokusekela, ukufakwa kwesitimela sekhadi, ukufakwa odongeni, ifomu lomkhiqizo lihlanganisa izingqimba ezintathu zokuphatha, ukuphathwa kwezingqimba ezimbili, ukungaphathwa, kungasetshenziswa kabanzi ohlelweni lwenethiwekhi. izimo zezimboni ezahlukahlukene kunethiwekhi yezimboni ye-Ethernet.
Phakathi kwazo, ekushintsheni kwezimboni, kufanele sikhulume ngokushintsha kwenethiwekhi yendandatho, kungase kube abangani bethu abaningi bokuphepha, ekushintsheni kwenethiwekhi yendandatho noma ulwazi oluncane, namuhla kanye ne-CF FIBERLINK ndawonye ukuze sikufunde!
1: ithini iswishi yenethiwekhi yendandatho
Ukushintsha kwenethiwekhi yendandatho kuwuhlobo olukhethekile lokushintshwa, ngoba ukushintshwa kwenethiwekhi yendandatho evamile kuwukushintsha kwezimboni, ngakho-ke kungabizwa ngokuvamile ngokuthi ukushintshwa kwenethiwekhi yebanga lezimboni, ukushintshwa kwenethiwekhi yendandatho kunezinzuzo eziningi esakhiweni senethiwekhi yendandatho, njengokungafuneki, ukwethembeka kanye njalonjalo. Ukushintsha kwenethiwekhi yokukhala kungakha inethiwekhi yeringi, iswishi ngayinye inezimbobo ezimbili zeqembu elikhalayo, phakathi kwamaswishi ngesandla esisesandleni se-topology yenethiwekhi eyindandatho. Inzuzo yokusungulwa kwayo ukuthi lapho isixhumanisi esithile kunethiwekhi yendandatho sinqanyuliwe, ngeke kuthinte ukuthunyelwa kwedatha kunethiwekhi, ngakho-ke ukushintshwa kwenethiwekhi yendandatho yethulwa emikhakheni eminingi yokuxhumana yezimboni. Ukushintsha kwenethiwekhi yeringi kusebenzisa ubuchwepheshe obukhethekile ukugwema ukukhiqizwa kwesiphepho sokusakaza futhi ubone ukwethembeka kwenethiwekhi yokukhala.
2: umsebenzi wokushintsha inethiwekhi yeringithoni
Kuhlelo lwenethiwekhi yekhompuyutha, ukushintsha kwenethiwekhi yeringi yethulwa ukuze kuhlangatshezwane nobuthakathaka bemodi yokusebenza okwabelwana ngayo. Ihabhu lingummeleli wemodi yomsebenzi owabiwe, uma ihabhu kumuntu weposi, ngakho-ke othumela iposi “uyisiwula” esingaziwa —— kuye ukuba alethe, akazi ngokuqondile ngokwekheli elisencwadini eya encwadini eya umamukeli, uzoyisa kuphela incwadi kubo bonke abantu, bese evumela umamukeli ngokwemininingwane yekheli ukuthi anqume eyakhe! Iswishi yokukhala iyiposi “ehlakaniphile” —— inkinobho yokukhala inebhasi elibuyela emuva elinomkhawulokudonsa ophezulu kanye ne-matrix yokushintshisana kwangaphakathi.
Ukushintsha kwenethiwekhi yokukhala kungakha inethiwekhi yeringi, iswishi ngayinye inezimbobo ezimbili zeqembu elikhalayo, phakathi kwamaswishi ngesandla esisesandleni se-topology yenethiwekhi eyindandatho. Inzuzo yokusungulwa kwayo ukuthi lapho isixhumanisi esithile kunethiwekhi yendandatho sinqanyuliwe, ngeke kuthinte ukuthunyelwa kwedatha kunethiwekhi, ngakho-ke ukushintshwa kwenethiwekhi yendandatho yethulwa emikhakheni eminingi yokuxhumana yezimboni. Ukushintsha kwenethiwekhi yeringi kusebenzisa ubuchwepheshe obukhethekile ukugwema ukukhiqizwa kwesiphepho sokusakaza futhi ubone ukwethembeka kwenethiwekhi yokukhala. Wonke amachweba okushintsha kwenethiwekhi yeringi alengiswa ebhasini elingemuva. Lapho isifunda sokulawula sithola iphakethe, imbobo yokucubungula izothola ithebula lokulawula ikheli enkumbulweni ukuze inqume i-NIC (ikhadi lenethiwekhi) yendawo okuyiwa kuyo i-MAC (ikheli lehadiwe lekhadi lenethiwekhi), futhi ngokushesha idlulisele iphakethe ethekwini okuyiwa kuyo. ngokusebenzisa i-matrix yokushintshanisa kwangaphakathi. Uma i-MAC ingekho, iswishi yenethiwekhi yokukhala isakaza kuzo zonke izimbobo. Ngemva kokuthola impendulo yembobo, ithuba "lokufunda" ikheli elisha futhi ulingeze kuthebula lekheli langaphakathi. Kungabonakala ukuthi lapho inkinobho yenethiwekhi yendandatho ithola "incwadi" ethunyelwe ikhadi elithile lenethiwekhi, izothumela ngokushesha incwadi kumamukeli ngokusho kolwazi lwekheli elingenhla kanye "nencwadi yokuhlala unomphela" yomninikhaya. Uma ikheli lomamukeli lingekho kurejista yasendlini, inkinobho yenethiwekhi yeringi izosabalalisa incwadi kuwo wonke umuntu njengehabhu, bese ithola umamukeli. Ngemva kokuthola umamukeli, ithuba lokushintshana kwenethiwekhi yendandatho lizobhalisa ngokushesha ulwazi lomuntu “kwirejista yasendlini”, ukuze ngemva kwenkonzo yamakhasimende, incwadi ihanjiswe ngokushesha.
3: isixazululo sokushintsha inethiwekhi yeringi
a）Iswishi yenethiwekhi yeringi yebanga lethrafikhi yebanga lezimboni
Isixazululo senethiwekhi
Lolu hlelo lwamukela uhlaka lwe-topology yenethiwekhi ye-hybrid enezingqimba ezintathu, ehlukaniswe izingxenye eziningana: ukufinyelela ezimpambanweni zomgwaqo, ukuhlangana kwe-intersection kanye nesikhungo sokuqapha.
1) ukufinyelela ezimpambanweni zomgwaqo: sebenzisa iswishi yenethiwekhi yendandatho ye-POE enezimbobo ezi-4 ukuze uxhume ikhamera ephambanayo neswishi, bese uyidlulisela kusendlalelo sokuhlangana komgwaqo ngokusebenzisa imbobo yokukhanya. Iswishi ngayinye yokufinyelela empambanweni yomgwaqo ixhunywe ekuhlanganeni kwempambanomgwaqo ngenethiwekhi yokukhala.
2) Ukuhlangana okuwelayo: Iswishi yenethiwekhi ye-PoE eyimbobo engu-8 ixhunywe kuswishi yokuhlangana kwe-intersection, bese idluliselwa esikhungweni sokuqapha ngembobo yokubona. Ngesikhathi esifanayo, ukuhlangana okuningi kwe-convergence kuxhunyiwe futhi kudluliselwe esikhungweni sokuqapha ngenethiwekhi yendandatho.
3) Isikhungo sokuqapha: sebenzisa ama-switch gigabit angu-24 anezingqimba ezintathu ukuze uqoqe futhi udlulisele umgwaqo ngamunye kusiwishi esimaphakathi, futhi ufinyelele kumaseva amaphakathi nemishini yokugcina.
b)Iswishi ye-Ethernet enomsebenzi wenethiwekhi eyindandatho
Imodi yenethiwekhi yokushintsha kwe-Ethernet ngomsebenzi wenethiwekhi yendandatho ngokuvamile isebenzisa imodi yokuxhuma yomdwebo wesihlahla, izama ukugwema ukwenza inethiwekhi ibe yiluphu.
4: izinzuzo zokushintshwa kwenethiwekhi yendandatho
a) Iswishi yenethiwekhi yeringi yezinga lezimboni Izinzuzo zokuxhumanisa amaringi
1)Inethiwekhi yokushintsha inethiwekhi yendandatho izinzile futhi isikhathi sokuzilapha sifushane.
2) Ekwakhiweni kwenethiwekhi yendandatho, lapho i-fiber eyodwa yokukhanya ivinjiwe, usebenzisa inkinobho yenethiwekhi yendandatho, ungakwazi ngokuzenzakalelayo ukugxumela kwenye intambo yokubona ukuze uqhubeke nokuxhumana.
3) Izinsiza zembobo namazinga okusetshenziswa komkhawulokudonsa wesixhumanisi aphezulu
4)Inethiwekhi ithembeke kakhulu ngemva kokusebenzisa uhlelo lwenethiwekhi yeringi ngokushintsha kwenethiwekhi yeringithoni.
b)Iswishi yenethiwekhi yeringi yezinga lemboni Ubuhle bokuxhumana okumise okwesihlahla
1)I-Ethernet shintsha inethiwekhi yesihlahla enomsebenzi wenethiwekhi eyindandatho igwema ukuguqulwa kwephrothokholi yokuxhumana futhi yenza kube lula ukuphatha.
2)Iswishi ye-Ethernet enomsebenzi wenethiwekhi eyindandatho ingagwema ngempumelelo isiphepho sokusakaza futhi iqinisekise ukusebenza okuvamile kweswishi.
3)Inethiwekhi yesihlahla sokushintsha i-Ethernet enomsebenzi wenethiwekhi yendandatho inezinzuzo zomkhawulokudonsa ophezulu wokudlulisa, ukwakheka kwenethiwekhi okuguquguqukayo, ukunwebeka okulula, ikhono lokusekela izinsiza eziningi, ukugcinwa okulula kanye nekhono eliqinile lokulwa nokuphazamiseka.
4)Iswishi ye-Ethernet enomsebenzi wenethiwekhi eyindandatho ingathola ukuvikeleka okungafuneki
