Kuyini ukushintsha kwenethiwekhi eyindandatho
Ukushintshwa kwenethiwekhi yendandatho kuwuhlobo olukhethekile lokushintshwa, ngoba ukushintshwa kwenethiwekhi yendandatho evamile kuwukushintsha kwezimboni, ngakho ngokuvamile kungabizwa ngokuthi ukushintshwa kwenethiwekhi yendandatho yezimboni, ukushintshwa kwenethiwekhi yendandatho kunezinzuzo eziningi esakhiweni senethiwekhi yendandatho, njengokuphindaphinda, ukwethembeka nokunye. ku. Ukushintsha kwenethiwekhi yokukhala kungakha inethiwekhi yendandatho, iswishi ngayinye inezimbobo ezimbili zeqembu elikhalayo, phakathi kwamaswishi ngesandla ngesandla kwakha i-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.
Okwesibili: indima yokushintsha inethiwekhi yeringi
Kuhlelo lwenethiwekhi yekhompuyutha, ukushintsha kwenethiwekhi yeringi yethulwa ukuze kuhlangatshezwane nobuthakathaka bemodi yokusebenza okwabelwana ngayo. I-Hub imele Imodi yomsebenzi owabiwe, uma ihabhu kumuntu weposi, ngakho-ke umuntu weposi “uyisiwula” —— kuye ukuba alethe, akazi ngokuqondile ngokwekheli elisencwadini eya ku- umamukeli, uzoyisa kuphela incwadi kubo bonke abantu, bese uvumela umamukeli ngokwemininingwane yekheli ukuthi ahlulele ukuthi eyakhe! Iswishi yokukhala iyiposi "ehlakaniphile" —— inkinobho yokukhala inebhasi elibuyela emuva elinomkhawulokudonsa ophezulu kanye ne-matrix yokushintshisana kwangaphakathi. Ukushintsha kwenethiwekhi yokukhala kungakha inethiwekhi yendandatho, iswishi ngayinye inezimbobo ezimbili zeqembu elikhalayo, phakathi kwamaswishi ngesandla ngesandla ukuze kwakhiwe i-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 le-hardware yekhadi lenethiwekhi), futhi ngokushesha idlulisele iphakethe embobeni 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 lenethiwekhi, izothumela ngokushesha incwadi kumamukeli ngokusho kolwazi lwekheli elingenhla kanye "nencwadi yokuhlala unomphela" yomphathi. Uma ikheli lomamukeli lingekho kurejista yasendlini, inkinobho yenethiwekhi yeringi izosabalalisa incwadi kuwo wonke umuntu njengehabhu, bese ithola umamukeli. Ngemva kokuthola umamukeli, ithuba lokushintshaniswa kwenethiwekhi yendandatho lizobhalisa ngokushesha ulwazi lomuntu "kwirejista yasendlini", ukuze ngemva kwenkonzo yamakhasimende, incwadi ingahanjiswa ngokushesha.
Okwesithathu: isisombululo sokushintsha inethiwekhi yeringi
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 ye-intersection kuswishi, bese udlulisela kusendlalelo sokuhlangana kwe-intersection ngembobo yokukhanya. Iswishi yokufinyelela ezimpambanweni zomgwaqo ngayinye ixhunywe ekuhlanganeni komgwaqo ngenethiwekhi yokukhala.
2) Ukuhlangana okuwelayo: inkinobho yenethiwekhi ye-PoE eyimbobo engu-8 ixhunywe kusishintshi sokuhlangana 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.
Imodi yokuxhumana ye-Ethernet ishintsha ngokusebenza kwenethiwekhi eyindandatho ngokuvamile isebenzisa imodi yokuxhuma yomdwebo wesihlahla, izama ukugwema ukwenza inethiwekhi ibe yiluphu.
Okwesine: izinzuzo zokushintshwa kwenethiwekhi yendandatho
Inethiwekhi yokushintsha inethiwekhi yendandatho izinzile futhi isikhathi sokuzilapha sifushane.
Ekwakhiweni kwenethiwekhi yendandatho, lapho i-fiber eyodwa ye-optical ivinjiwe, usebenzisa inkinobho yenethiwekhi yendandatho, ungakwazi ngokuzenzakalelayo ukugxumela kwenye intambo yokubona ukuze uqhubeke nokuxhumana.
Izinsiza zembobo namazinga okusetshenziswa komkhawulokudonsa wesixhumanisi aphezulu
Inethiwekhi ithembeke kakhulu ngemva kokusebenzisa uhlelo lwenethiwekhi yeringi ngokushintsha kwenethiwekhi yeringithoni.
Inethiwekhi ye-Ethernet yokushintsha isihlahla enomsebenzi wenethiwekhi eyindandatho igwema ukuguqulwa kwephrothokholi yokuxhumana futhi isiza ukuphatha.
Iswishi ye-Ethernet enomsebenzi wenethiwekhi eyindandatho ingagwema ngempumelelo isiphepho sokusakaza futhi iqinisekise ukusebenza okuvamile kweswishi.
Inethiwekhi ye-Ethernet yokushintsha isihlahla esinomsebenzi wenethiwekhi yendandatho inezinzuzo zomkhawulokudonsa ophezulu wokudlulisa, ukwakheka kwenethiwekhi okuguquguqukayo, ukunwebeka okulula, ikhono lokusekela izinsiza eziningi, ukugcinwa okulula kanye nokuphikisana okuqinile.
Iswishi ye-Ethernet enomsebenzi wenethiwekhi eyindandatho ingathola ukuvikeleka okungafuneki
