Yintoni iswitshi yenethiwekhi yeringi
Umnatha womnatha wokutshintsha luhlobo olukhethekileyo lokutshintshela, kuba iswitsha yenethiwekhi yekhonkco yesiqhelo iyiswitsha yeshishini, ngoko ke inokubizwa ngokuba yitshintshi yenethiwekhi yomsesane weshishini, iswitsha yenethiwekhi yomsesane ineenzuzo ezininzi kwisakhiwo sothungelwano lweringi, njengokungafuneki, ukuthembeka kunye nokunye. kwi. Iiswitshi womnatha Ring unokwenza inethiwekhi ring, iswitsha nganye inezibuko ezimbini kwiqela ring, phakathi kokutshintsha ngesandla ngesandla ukwenza topology ring womnatha. Inzuzo yokusekwa kwayo kukuba xa ikhonkco elithile kuthungelwano lwendandatho luqhawulwe, aluyi kuchaphazela ukuthunyelwa kwedatha kuthungelwano, ngoko ke umnxibelelwano womnatha uqaliswa kwiindawo ezininzi zonxibelelwano lwezoshishino. Ukutshintsha kwenethiwekhi yeringi kwamkela ubugcisa obukhethekileyo bokunqanda ukuveliswa kwesaqhwithi sosasazo kunye nokuqonda ukuthembeka kwenethiwekhi yeringi.
Ezimbini: indima yokutshintsha inethiwekhi yeringi
Kwinkqubo yenethiwekhi yekhompyuter, iswitshi yenethiwekhi yeringi yaziswa ukuhlangabezana nobuthathaka bendlela yokusebenza ekwabelwana ngayo. I-Hub ngummeli we-Shared work mode, ukuba i-hub kwi-postman, ngoko unoposi "usisidenge" -- kuye ukuhambisa, akazi ngokuthe ngqo ngokwedilesi kwileta eya kwileta umamkeli, uya kuthatha kuphela ileta kubo bonke abantu, kwaye ke umamkeli ngokweenkcukacha idilesi ukuba agwebe ukuba eyakhe! Ukutshintsha kweringi ngumntu weposi "ohlakaniphileyo" —— iswitshi yeringi inebhasi ephezulu yokubuyela umva kunye ne-matrix yotshintshiselwano lwangaphakathi. Utshintsho womnatha weringi unokwenza uthungelwano lwendandatho, iswitshi nganye inamazibuko amabini kwiqela le-ring, phakathi kokutshintsha ngesandla kwifomu yesandla ukwenza i-topology yenethiwekhi yeringi. Inzuzo yokusekwa kwayo kukuba xa ikhonkco elithile kuthungelwano lwendandatho luqhawulwe, aluyi kuchaphazela ukuthunyelwa kwedatha kuthungelwano, ngoko ke umnxibelelwano womnatha uqaliswa kwiindawo ezininzi zonxibelelwano lwezoshishino. Ukutshintsha kwenethiwekhi yeringi kwamkela ubugcisa obukhethekileyo bokunqanda ukuveliswa kwesaqhwithi sosasazo kunye nokuqonda ukuthembeka kwenethiwekhi yeringi. Onke amazibuko okutshintsha kwenethiwekhi yeringi axhonywe kwibhasi engasemva. Xa isiphaluka solawulo sifumana ipakethi, i-port yokucubungula iya kufumana itafile yokulawula idilesi kwimemori ukumisela i-NIC (ikhadi lenethiwekhi) yendawo ekuyiyo i-MAC (idilesi ye-hardware yekhadi lomnatha), kwaye ngokukhawuleza uthumele ipakethi kwi-port yendawo i-matrix yotshintshiselwano lwangaphakathi. Ukuba iMAC ayikho, iswitshi yenethiwekhi yeringi isasaza kuwo onke amazibuko. Emva kokufumana impendulo yechweba, ithuba "lokufunda" idilesi entsha kwaye uyongeze kwitafile yedilesi yangaphakathi. Ingabonwa ukuba xa iswitshi yomnatha wendandatho ifumana "ileta" ethunyelwe ngekhadi lomnatha, iya kuthumela ngokukhawuleza ileta kumamkeli ngokweenkcukacha zedilesi engentla kunye "nencwadi yokuhlala esisigxina" yomninimzi. Ukuba idilesi yomamkeli ayikho kwirejista yendlu, iswitshi yenethiwekhi yeringi iya kusasaza ileta kumntu wonke njenge hub, kwaye emva koko ufumane ummkeli. Emva kokufumana ummkeli, ithuba lokutshintshiselana kwenethiwekhi yekhonkco liya kubhalisa ngokukhawuleza ulwazi lomntu "kwirejista yendlu", ukwenzela ukuba emva kwenkonzo yabathengi, ileta inokuhanjiswa ngokukhawuleza.
Ezintathu: isisombululo sokutshintsha inethiwekhi yeringi
Esi sikimu samkela isakhelo se-topology yothungelwano olunemigangatho emithathu, eyahlulahlulwe yangamacandelo aliqela: ukufikelela kwi-intersection, i-intersection convergence kunye neziko lokubeka iliso.
I-1) ukufikelela kwi-intersection: sebenzisa i-4-port ye-POE ring network switch ukudibanisa ikhamera ye-intersection kwi-switch, kwaye emva koko udlulisele kwi-intersection convergence layer ngokusebenzisa i-port yokukhanya. Ukutshintsha kofikelelo kwisiphambuka ngasinye siqhagamshelwe kwi-convergence ye-intersection ngenethiwekhi yeringi.
I-2) Ukuwela ukudibanisa: i-8-port ye-PoE ring network switch ixhunyiwe kwi-intersection convergence switch, kwaye emva koko idluliselwe kwiziko lokubeka iliso nge-port optical. Ngexesha elifanayo, iindlela ezininzi zokuhlangana zixhunyiwe kwaye zithunyelwa kwiziko lokubeka iliso ngokusebenzisa inethiwekhi yendandatho.
I-3) Iziko lokubeka iliso: sebenzisa i-gigabit ye-24-layer-layer switches ukuqokelela kunye nokudlulisa i-intersection nganye kwi-switch central, kwaye ufikelele kwiiseva eziphambili kunye nezixhobo zokugcina.
Imowudi yothungelwano ye-Ethernet itshintsha kunye nomsebenzi womnatha womsesane ngokuqhelekileyo usebenzisa imowudi yoqhagamshelo lomzobo womthi, uzama ukuphepha ukwenza inethiwekhi ibe yiluphu.
Isine: iingenelo zokutshintsha kwenethiwekhi yeringi
Umnatha womnatha wokutshintsha inethiwekhi uzinzile kwaye ixesha lokuziphilisa lifutshane.
Kulwakhiwo lothungelwano lwendandatho, xa ifayibha enye ivaliwe, usebenzisa iswitsha yenethiwekhi yeringi, ungatsibela ngokuzenzekelayo kwenye intambo yokubona ukuqhubeka nonxibelelwano.
Izixhobo zePort kunye namazinga okusetyenziswa kwe-bandwidth yekhonkco aphezulu
Uthungelwano luthembeke ngakumbi emva kokusebenzisa iskimu senethiwekhi yeringi kunye neswitshi yenethiwekhi yeringi.
I-Ethernet yokutshintsha umnatha womthi kunye nomsebenzi womnatha womnxeba uthintela ukuguqulwa kweprotocol yonxibelelwano kwaye iququzelele ulawulo.
Ukutshintsha kwe-Ethernet kunye nomsebenzi womnatha womnatha unokuphepha ngokufanelekileyo isaqhwithi sosasazo kunye nokuqinisekisa ukusebenza okuqhelekileyo kokutshintsha.
Uthungelwano lomthi wokutshintsha kwe-Ethernet kunye nomsebenzi womnatha womnatha uneenzuzo ze-bandwidth ephezulu yokudluliselwa, isakhiwo senethiwekhi eguquguqukayo, kulula ukwandisa, ubuchule benkxaso yeenkonzo ezininzi, ukugcinwa lula kunye nokuphazamiseka okunamandla okuchasayo.
Ukutshintsha kwe-Ethernet kunye nomsebenzi womnatha womsesane unokuqonda ukhuseleko olungafunekiyo
