Okokuqala, masigxininise koku:
Ukutshintsha okungundoqo akulohlobo lokutshintsha,
Lutshintsho olubekwe kumqolo ongundoqo (umqolo womnatha).
1. Yintoni i-core switch
Ngokubanzi, uthungelwano lwamashishini amakhulu kunye neekhefi ze-intanethi kufuneka zithenge iiswitshi ezingundoqo ukuphumeza amandla okwandisa inethiwekhi kunye nokukhusela utyalo-mali olukhoyo. Kuphela xa inani leekhomputha lifikelela kwinqanaba elithile lingasetyenziselwa ukutshintshwa kwengundoqo, ngelixa akukho mfuneko yokutshintsha okungundoqo ngaphantsi kwe-50, kwaye umzila wanele. Into ebizwa ngokuba yi-core switch ibhekiselele kwi-architecture yenethiwekhi. Ukuba inethiwekhi yendawo encinci kunye neekhomputha ezininzi, i-8-port encinci yokutshintsha ingabizwa ngokuba yi-core switch. Iiswitshi ezingundoqo ngokubanzi zibhekisa kuLuleko lwesi-2 okanye kuMaleko wesi-3 wokutshintsha okunemisebenzi yolawulo yothungelwano kunye nokuphuma ngamandla. Kwindawo yothungelwano kunye neekhomputha ezingaphezu kwe-100, utshintsho olungundoqo luyimfuneko ekusebenzeni okuzinzile kunye nesantya esiphezulu.
2. Umahluko phakathi kokutshintsha okungundoqo kunye rhoqo
iiswitshi: Inani lezibuko ngokutshintsha rhoqo ngokuqhelekileyo 24-48, kwaye uninzi lwamazibuko womnatha gigabit Ethernet okanye gigabit Ethernet izibuko. Umsebenzi ophambili kukufikelela kwidatha yomsebenzisi okanye ukuqokelela idatha yokutshintsha ukusuka kwezinye iileya zofikelelo. Olu hlobo lokutshintsha lunokuqwalasela kunye ne-Vlan ye-protocol elula yomzila kunye neminye imisebenzi ye-SNMP elula kakhulu, kwaye i-backplane bandwidth incinci. Kukho inani elikhulu lamazibuko okutshintsha okungundoqo, adla ngokuba yimodyuli kwaye anokudityaniswa ngokukhululekileyo kunye namazibuko okukhanya kunye namazibuko e-gigabit Ethernet. Ngokubanzi, iiswitshi ezingundoqo zizitshixo ezinomaleko amathathu ezinokuseta iiprothokholi ezahlukeneyo zothungelwano eziphambili ezifana neendlela ezilandelwayo/ACL/QoS/ukulinganisa umthwalo. Eyona ngongoma ibalulekileyo kukuba i-backplane bandwidth yokutshintsha okungundoqo iphezulu kakhulu kunokutshintsha okuqhelekileyo, kwaye ngokuqhelekileyo banemodyuli ye-injini eyahlukileyo kwaye yeyokuqala kunye ne-backup. Umahluko phakathi kwabasebenzisi abaqhagamshelayo okanye abafikelela kuthungelwano: Inxalenye yothungelwano ejongene ngqo nabasebenzisi abaqhagamshelayo okanye abafikelela kuthungelwano idla ngokubizwa ngokuba ngumaleko wofikelelo, kwaye inxalenye phakathi komgangatho wofikelelo kunye nenqanaba elingundoqo libizwa ngokuba lusasazo. umaleko okanye umaleko wokudityaniswa. Injongo yoluhlu lokufikelela kukuvumela abasebenzisi bokugqibela ukuba badibanise kwinethiwekhi, ngoko ke ukutshintshiselana komgangatho wokufikelela kuneempawu zeendleko eziphantsi kunye nobuninzi be-port. Ukutshintsha kwe-convergence layer yindawo yokudibanisa yokutshintsha komgangatho wofikelelo oluninzi, ekufuneka ikwazi ukuphatha yonke i-traffic ukusuka kwizixhobo zokufikelela kwi-maleko kunye nokubonelela nge-uplink kwi-core layer. Ke ngoko, iiswitshi zomaleko odityanisiweyo zinokusebenza okuphezulu, ujongano olumbalwa, kunye namazinga aphezulu okutshintsha. Umqolo wothungelwano ubizwa ngokuba ngumaleko ongundoqo, onjongo yawo iphambili kukubonelela ngesakhiwo esiphuculweyo nesithembekileyo sokuhanjiswa komqolo ngonxibelelwano olukhawulezayo lokudlulisa. Ke ngoko, usetyenziso olungundoqo lokutshintsha umaleko lunokuthembeka okuphezulu, ukusebenza, kunye nokugqithisa.
Xa kuthelekiswa nokutshintsha okungundoqo okuqhelekileyo, kufuneka babe neempawu ezifana ne-cache enkulu, umthamo ophezulu, i-virtualization, i-scalability, kunye ne-module redundancy technology. Okwangoku, imarike yokutshintsha ixutywe, kwaye umgangatho wemveliso awulingani. Abasebenzisi banokunikela ingqalelo kwi-CF FIBERLINK ekukhetheni imveliso, kwaye ngokuqinisekileyo kukho utshintsho olungundoqo olufanelekileyo kuwe!
