Esimweni sanamuhla esivela ngokushesha esimbonini, isidingo samanethiwekhi okuxhumana athembekile futhi asebenza kahle abaluleke kakhulu kunangaphambili.Ukushintshwa kwe-ethernet kwe-ethernetDlala indima ebalulekile ekuqinisekiseni ukuhanjiswa kwedatha okungenamswalo kanye nokuxhumeka kwenethiwekhi ezindaweni zezimboni. Phakathi kwezinhlobo ezahlukahlukene zokushintshwa kwe-Ethernet zezimboni, ukushintshwa okuphethwe kuvelele izici zazo ezithuthukile nokusebenza. Kulesi sihloko, sizobhekisisa izinzuzo zokushintshwa kwe-ethernet yezezimboni eziphathwayo nokuthi kungani zigxeka izicelo zesimanje zezimboni.
Ukushintshwa kwe-Ethernet okuphathelene nezimboni kunikeza izinga eliphakeme lokulawula nokwenza ngokwezifiso ukwedlula ukushintshwa okungafanele. Ngokushintshwa okulawulwa, abaphathi benethiwekhi bangahlelela futhi baphathe izilungiselelo zokushintsha, babeke phambili ithrafikhi, baqaphe ukusebenza kwenethiwekhi, futhi basebenzise izindlela zokuphepha. Leli zinga lokulawula libalulekile ezindaweni zezimboni lapho ukuthembeka kanye nokuphepha kwenethiwekhi kubaluleke kakhulu.
Enye yezinzuzo eziphambili zokuphathwaukushintshwa kwe-ethernet kwe-ethernetIkhono labo lokusekela izici zekhwalithi yensizakalo (QOS). Ama-Qos avumela ithrafikhi ebalulekile yedatha ukuthi ibekwe phambili, uqinisekise ukuthi imininingwane ebucayi yesikhathi efana nezimpawu zokulawula noma idatha yokuqapha yesikhathi sangempela ibeka phambili kwithrafikhi engabalulekile. Lokhu kwakwazi okubaluleke kakhulu ezinhlelweni zezezimboni ze-automation kanye nokulawula, lapho ukuxhumana kwesikhathi sangempela kubalulekile ukuze kugcinwe ukusebenza kahle nokuphepha.
Ngaphezu kwalokho, ukushintshwa okuphethwe kuhlinzeka ngezinto zokuphepha zenethiwekhi ezithuthukisiwe, kufaka phakathi uhlu lokulawula ukufinyelela, ukuphepha ethekwini, kanye nokuxhaswa kwe-Virtual Lan (VLAN). Lezi zinyathelo zokuphepha zisiza ukuvikela amanethiwekhi wezimboni ekufinyeleleni okungagunyaziwe, ukuphazamiseka kanye nezinsongo ze-cyber ezingaba khona. Esikhathini esenyukayo esenyukayo ye-cyberattacks, izici zokuphepha eziqinile ezinikezwe ukushintshwa okulawulwa zibalulekile ekuvikeleni ingqalasizinda ebucayi kanye nedatha ebucayi.
Enye inzuzo yokushintshwa kwezimboni ethernet ukushintshwa kokusekelwa kwamaphrothokholi wokuphatha athuthukile njenge-protocol elula ukuphathwa kwenethiwekhi (i-SNMP) nokuqapha okukude (i-RMMM). Lezi protocol zinika amandla ukuqapha kwenethiwekhi okusebenzayo, ukusebenza kahle kokusebenza, kanye nokuxazulula inkinga, okuvumela abaphathi ukuthi bakwazi ukubona futhi baxazulule izingqinamba ezingaba khona ngaphambi kokuba bathinte imisebenzi. Amandla okubheka kude futhi aphathe amanethiwekhi wezimboni azuzisa kakhulu izikhungo ezinkulu zezimboni nezinhlelo ezisatshalaliswa.
Ngaphezu kwalokho, ukushintshwa okuphethwe kuhlinzeka ngokuguquguquka okukhulu kanye nokulinganisa, okuvumela ukudalwa kwama-topologies abumba amanethiwekhi kanye nokuhlanganiswa kwamadivayisi ahlukahlukene wezimboni nezinqubomgomo. Noma ngabe ukuxhuma ama-PLCs, HMIS, izinzwa noma eminye imishini yezimboni, ukushintshwa okuphethwe kunikeza ukusebenza okudingekayo ukuze uhlangabezane nezidingo zenethiwekhi ezahlukahlukene. Ngokwengeziwe, amandla okuhlanganyela inethiwekhi esebenzisa amaVlans anika amandla ukuphathwa kwethrafikhi efanelekile nokuhlukaniswa kwamadivayisi abucayi noma ama-subsystems ahlukahlukene.
Ngamafuphi, izinzuzo zokuphathwaukushintshwa kwe-ethernet kwe-ethernetkucacile. Ukusuka ekuphathweni okuthuthukile kanye nokuphepha kumandla wokuphatha athuthukile kanye nokuguquguquka, ukushintshwa okuphethwe kubalulekile ezinhlelweni zesimanje zezimboni. Njengoba amanethiwekhi wezimboni ayaqhubeka nokuvela futhi anwebe, indima yokushintshwa okulawulwa ekuqinisekiseni ingqalasizinda yezokuxhumana ethembekile futhi esebenza kahle izoba abaluleke kakhulu. Ngokuqonda ukushintshwa kwezimboni ze-Ethernet eziphathwayo, amabhizinisi angenza izinqumo ezinolwazi lapho esebenzisa amanethiwekhi wezimboni aqinile futhi aqine.
