Ukushintsha kwezimbonizenzelwe ngokukhethekile ukuhlangabezana nezidingo zezinhlelo zokusebenza zezimboni eziguquguqukayo nezishintshayo futhi zinikeze isisombululo sokuxhumana se-Ethernet yezimboni esingabizi.Ukushintsha kwezimboni, njengamadivayisi wethu wehadiwe we-LAN asetshenziswa kabanzi, bekulokhu kujwayelekile kuwo wonke umuntu.Ukuduma kwayo empeleni kungenxa yokusetshenziswa okubanzi kwe-Ethernet, njengemishini yanamuhla ye-Ethernet ejwayelekile, kuzoba khona imishini enjalo cishe kuwo wonke amanethiwekhi endawo.

Ukushintsha kwezimboni amaswishi asekelwe ku-Ethernet ukuze kudluliselwe idatha, futhi i-Ethernet isebenzisa inethiwekhi yendawo yasendaweni eyabelana ngendlela yokudlulisela yohlobo lwebhasi.Isakhiwo seswishi ye-Ethernet ukuthi imbobo ngayinye ixhumeke ngokuqondile kumsingathi, futhi ngokuvamile isebenza ngemodi ye-duplex egcwele.Iswishi ingaxhumeka kumapheya amaningi ezimbobo ngesikhathi esisodwa, ukuze ipheya ngayinye yabasingathi abaxhumanayo bakwazi ukudlulisa idatha ngaphandle kokungqubuzana njengokungathi iyindawo yokuxhumana ekhethekile.Uma ubheka i-topology elandelayo, uzothola ukuthi esimweni sokusebenzisa i-topology yenkanyezi, nakanjani kuyoba khona ukushintshwa ku-Ethernet, ngoba bonke ababungazi baxhumeke ekushintsheni kwezimboni besebenzisa izintambo ukuxhuma komunye nomunye.

Eqinisweni, ku-topology yenkanyezi yokuqala, idivayisi evamile yokuxhuma ikhebula phakathi "yi-HUB (ihabhu)", kodwa ama-hubs anezinkinga ezifana nomkhawulokudonsa okwabiwe, izingxabano phakathi kwamachweba, ngoba wonke umuntu uyazi ukuthi i-Ethernet ejwayelekile "ihabhu".Inethiwekhi yokungqubuzana” isho ukuthi endaweni ebizwa ngokuthi “isizinda sokungqubuzana”, okungenani ama-node amabili angakwazi ukuxhumana.Ngaphezu kwalokho, nakuba ihabhu linamachweba amaningi, isakhiwo sayo sangaphakathi siyilokho okubizwa ngokuthi "isakhiwo sebhasi" se-Ethernet, okusho ukuthi kukhona "umugqa" owodwa ngaphakathi wokuxhumana.Uma usebenzisa idivayisi yehabhu, isibonelo, uma amanodi phakathi kwezimbobo 1 kanye no-2 exhumana, ezinye izimbobo zidinga ukulinda.Isenzakalo esibangelwa ngokuqondile ukuthi, isibonelo, kuthatha imizuzu eyi-10 ukudlulisa idatha phakathi kwama-node axhunywe kumachweba 1 no-2, futhi izindawo lapho amachweba 3 no-4 atholakala ngesikhathi esifanayo nawo aqala ukudlulisa idatha ngale hub, izingxabano. nomunye, okubangela lokho wonke umuntu akudingayo Isikhathi sizoba side, futhi kungathatha imizuzu engama-20 ukuqedela ukudlulisela.Okusho ukuthi, lapho izimbobo eziningi kuhabhu ezixhumana zodwa, kuba bucayi kakhulu ukungqubuzana, futhi kuthatha isikhathi eside ukudlulisa idatha.

Izici ezingokoqobo zokushintsha kwezimboni zibhekisela ezicini zokubukeka, izici zokuxhuma ngokomzimba, ukumiswa kwembobo, uhlobo oluyisisekelo, amandla okunweba, amandla okupakisha kanye nezilungiselelo zenkomba ezinikezwe iswishi, ebonisa isimo esiyisisekelo seswishi.

Ubuchwepheshe bokushintsha umkhiqizo onezici zobulula, intengo ephansi, ukusebenza okuphezulu kanye nokuminyana kwechweba eliphezulu, okuhlanganisa ubuchwepheshe bokushintsha obuyinkimbinkimbi bobuchwepheshe bokubhula ungqimba lwesibili lwemodeli yereferensi ye-OSI.Njengebhuloho, iswishi senza isinqumo esilula sokudlulisa ulwazi ngokwekheli le-MAC ephaketheni ngalinye.Futhi lesi sinqumo sokudlulisa ngokuvamile asicabangi olunye ulwazi olujulile olufihlwe ephaketheni.Umehluko ngamabhuloho ukuthi ukubambezeleka kokudlulisela iswishi kuncane kakhulu, kuseduze nokusebenza kwe-LAN eyodwa, futhi kudlula kude ukusebenza kokudlulisela phakathi kwamanethiwekhi avamile okuxhumana ahlanganisiwe.

Ukushintsha ubuchwepheshe kuvumela ukulungiswa komkhawulokudonsa kumasegimenti e-LAN okwabelwana ngawo nazinikele ukuze kuncishiswe izingqinamba ekuhambeni kolwazi phakathi kwama-LAN.Kunemikhiqizo eshintshayo ye-Ethernet, Fast Ethernet, FDDI kanye nobuchwepheshe be-ATM.

Ukusetshenziswa kwamasekhethi adidiyelwe aklanywe ngokukhethekile kwenza ukushintshwa kudlulise ulwazi ngokufana kuwo wonke amachweba ngesilinganiso somugqa, kunikeze ukusebenza okuphezulu kakhulu kunamabhuloho endabuko.Ubuchwepheshe besekethe obukhethekile bohlelo lokusebenza buvumela ukushintshwa ukuthi kusebenze ngokusebenza okukhulunywe ngenhla esimweni samachweba amaningi, futhi izindleko zayo zembobo ziphansi kunalezo zebhuloho lendabuko.

Amaswishi ezimboni asetshenziswa kakhulu.Mayelana nezicelo zemboni, zisetshenziswa kakhulu kulokhu: ukuphepha kwezimayini zamalahle, ezokuthutha ngololiwe, ezishintshayo zasembonini, izinhlelo zokuhlanza amanzi, ezokuphepha zasemadolobheni, njll.
