Njengomkhiqizo obalulekile wokuxhumana kwedatha,ukushintshwa kwe-Ethernet yezimbonikufanele ivuleke futhi ihambisane nemikhiqizo evela kubakhiqizi abaningi ukuze kuqinisekiswe ukusebenza okuzinzile nokuphephile kwesikhathi eside kohlelo.Uma uthembele kuphela kumkhiqizi othile, ubungozi buphezulu kakhulu.Ngakho-ke, ngokusekelwe ekucabangeni kokulinganisa nokuhambisana, ukucabangela okuphelele kufanele kunikezwe ukuxubaukushintshwa kwe-Ethernet yezimbonikusukela kubakhiqizi abahlukene ukuze bakhe inethiwekhi yendandatho engasasebenzi ukuze kwakhiwe isisekelo esiqinile sokunwetshwa kwenethiwekhi kwesikhathi esizayo.Ngakho-ke, ingabe ukushintshwa kwe-Ethernet yezimboni kusuka kubakhiqizi abahlukene kungakha ainethiwekhi yendandatho engasasebenzi?

Impendulo ithi yebo.Amaswishi e-Industrial Ethernet avela kubakhiqizi abahlukene angaxhumana ngomunye nomunye nge-loop kagesi port kanye ne-optical port.

⑴ Iphrothokholi yokuxhumana

Izindinganiso zikazwelonke ezifanele, izindinganiso zebhizinisi lase-Guodian, kanye namazinga embonini akhiwayo abeka ngokucacile ukuthi “inethiwekhi ingakhiwa ngokuvumelana nezidingo zohlelo lwamandla, futhi iphrothokholi yokuxhumana kufanele yamukele izivumelwano ezijwayelekile zamazwe ngamazwe:RSTP, MSTP, njll.”.Ngakho-ke, ngaphezu kokusekela iphrothokholi yeNdandatho yangasese enamalungelo empahla yobuhlakani ezimele athuthukiswe umkhiqizi ngamunye, ukushintshwa kwe-Ethernet yezimboni kufanele futhi kusekele i-RSTP ne-MSTP amaphrothokholi enethiwekhi yeringi yamazwe ngamazwe ajwayelekile.Uma nje i-RSTP ne-MSTP izimiso ezijwayelekile zenethiwekhi yendandatho yamazwe ngamazwe zamukelwa, amaswishi e-Ethernet yezimboni avela kubakhiqizi abahlukene angakha amanethiwekhi anezakhiwo ze-topological ezifana nenkanyezi, iringi, nesihlahla.

⑵ isendlalelo esibonakalayo

Ayikho inkinga ekuxhumekeni nasekuxhumaneni kwamaswishi avela kubakhiqizi abahlukene ezingeni elibonakalayo, inqobo nje uma amapharamitha emidiya evumelana, njengokuthi ingabe i-industrial-grade optical fiber transceiver iyimodi eyodwa noma imodi eminingi, kanye nobude begagasi. imingcele ye-optical fiber transceiver.Ukufingqa, kungakhathaliseki ukuthi iyiphi iphrothokholi yenethiwekhi noma isendlalelo esibonakalayo, amaswishi avela kubakhiqizi abahlukene angaxhumana lapho enza inethiwekhi yeringi efanayo.
