Okokuqala, ake sigxile kulokhu:
Ukushintshwa okuyisisekelo akulona uhlobo lokushintshwa,
Kuyiswishi ebekwe kungqimba oluwumgogodla (umgogodla wenethiwekhi).
1. Iyini i-core switch
Ngokuvamile, amanethiwekhi amabhizinisi amakhulu namakhefi e-inthanethi adinga ukuthenga amaswishi abalulekile ukuze kuzuzwe amakhono aqinile okunweba inethiwekhi nokuvikela ukutshalwa kwezimali okukhona. Kuphela uma inani lamakhompiyutha lifinyelela izinga elithile kungasetshenziswa ukushintsha okuyisisekelo, kuyilapho ngokuyisisekelo asikho isidingo sokushintshwa okuyisisekelo ngaphansi kuka-50, futhi umzila wanele. Okubizwa ngokuthi i-core switch ibhekisela ekwakhiweni kwenethiwekhi. Uma kuyinethiwekhi yendawo encane enamakhompuyutha amaningana, inkinobho encane enembobo engu-8 ingabizwa ngokuthi i-core switch. Ukushintsha okuyisisekelo ngokuvamile kubhekisela ekushintsheni Kwesendlalelo 2 noma Kwesendlalelo 3 anakho kokubili imisebenzi yokuphatha inethiwekhi nokuphuma okuqinile. Endaweni yenethiwekhi enamakhompyutha angaphezu kwe-100, ukushintshwa okuyisisekelo kubalulekile ekusebenzeni okuzinzile nokushesha kakhulu.
2. Umehluko phakathi kokushintsha okuyisisekelo nokujwayelekile
amaswishi: Inani lezimbobo ekushintsheni okujwayelekile ngokuvamile lingu-24-48, futhi iningi lamachweba enethiwekhi amachweba we-gigabit Ethernet noma we-gigabit Ethernet. Umsebenzi oyinhloko ukufinyelela idatha yomsebenzisi noma ukuqoqa idatha yokushintsha kwezinye izendlalelo zokufinyelela. Lolu hlobo lokushintsha lungalungiselelwa ngephrothokholi yomzila elula ye-Vlan neminye imisebenzi elula ye-SNMP kakhulu, futhi umkhawulokudonsa ongemuva mncane uma kuqhathaniswa. Kunenombolo enkulu yezimbobo zokushintshela eziyinhloko, ezivame ukuba yi-modular futhi zingamataniswa ngokukhululekile nezimbobo zokubona kanye nezimbobo ze-gigabit Ethernet. Ngokuvamile, ukushintshwa okuyinhloko kuwukushintsha kwezendlalelo ezintathu okungasetha izimiso zenethiwekhi ezithuthukisiwe ezihlukahlukene njengezivumelwano zomzila/ACL/QoS/load balancing. Iphuzu elibaluleke kakhulu ukuthi umkhawulokudonsa ongemuva we-backplane wokushintsha okuyisisekelo uphakeme kakhulu kunalowo wokushintsha okujwayelekile, futhi ngokuvamile anamamojula enjini ahlukene futhi ayisisekelo nesipele. Umehluko phakathi kwabasebenzisi abaxhumayo noma abafinyelela kunethiwekhi: Ingxenye yenethiwekhi ebheke ngqo abasebenzisi abaxhumayo noma abafinyelela kunethiwekhi ngokuvamile ibizwa ngokuthi isendlalelo sokufinyelela, futhi ingxenye ephakathi kwesendlalelo sokufinyelela nesendlalelo esiyinhloko sibizwa ngokuthi ukusatshalaliswa. isendlalelo noma isendlalelo sokuhlanganisa. Injongo yesendlalelo sokufinyelela iwukuvumela abasebenzisi bokugcina ukuthi baxhume kunethiwekhi, ngakho-ke iswishi yesendlalelo sokufinyelela inezici zezindleko eziphansi kanye nokuminyana kwembobo ephezulu. Iswishi yesendlalelo sokuhlangana iyindawo yokuhlangana yokushintsha kwesendlalelo sokufinyelela okuningi, okumele ikwazi ukuphatha yonke i-traffic kusuka kumadivayisi wesendlalelo sokufinyelela futhi inikeze i-uplink kuya kusendlalelo esiyinhloko. Ngakho-ke, ukushintshwa kwesendlalelo sokuhlanganisa kunokusebenza okuphezulu, ukuxhumana okumbalwa, namazinga okushintsha aphezulu. Umgogodla wenethiwekhi ubizwa ngokuthi ungqimba oluyinhloko, inhloso yalo enkulu ukuhlinzeka ngesakhiwo sokudlulisa umgogodla esithuthukisiwe nesithembekile ngokusebenzisa ukuxhumana kokudlulisela phambili ngesivinini esikhulu. Ngakho-ke, uhlelo lokusebenza lokushintsha ungqimba oluyisisekelo lunokwethenjelwa okuphezulu, ukusebenza, kanye nokusebenza.
Uma kuqhathaniswa nokushintsha okuyisisekelo okujwayelekile, badinga ukuba nezici ezifana nenqolobane enkulu, umthamo omkhulu, ukwenziwa kwezinto ezibonakalayo, ukuqina, nobuchwepheshe bokuphindaphinda kwemojuli. Njengamanje, imakethe yokushintsha ixubile, futhi ikhwalithi yomkhiqizo ayilingani. Abasebenzisi banganaka i-CF FIBERLINK ekukhetheni umkhiqizo, futhi kuneswishi eyodwa ewumongo elungele wena!
