Uyazi ukuthi yiziphi izimbobo ezizinikezele zokushintsha phezulu naphansi?
Iswishi iyidivayisi yokudlulisa idatha yenethiwekhi, futhi izimbobo zokuxhuma phakathi kwamadivayisi akhuphukayo nomfula axhumeka kuwo abizwa ngokuthi izimbobo ezixhuma phezulu neziphansi.Ekuqaleni, kwakukhona incazelo eqinile yokuthi iyiphi imbobo ekushintsheni.Manje, awukho umehluko oqinile onjalo phakathi kokuthi iyiphi imbobo ekushintsheni, njengakudala, bekunezindawo eziningi zokusebenzelana nezimbobo ekushintsheni.Manje, isibonelo, i-switch ye-16 way, uma uyitholile, ungabona ngokuqondile ukuthi inamachweba angu-16.
Amaswishi asezingeni eliphezulu kuphela ahlinzeka ngezimbobo ezimbalwa ezizinikezele ze-uplink ne-downlink, futhi ngokuvamile isivinini sokuxhuma sezimbobo ezizinikezele ze-uplink ne-downlink siyashesha kakhulu kunezinye izimbobo.Isibonelo, ukushintshwa kwezimbobo okuthuthukisiwe okungu-26 kuhlanganisa izimbobo ezingu-24 100 Mbps nezimbobo ezingu-2 1000 Mbps.I-100 Mbps isetshenziselwa ukuxhuma amakhompyutha, amarutha, amakhamera enethiwekhi, futhi 1000 Mbps asetshenziselwa ukuxhuma amaswishi.
Izindlela ezintathu zokuxhuma zokushintshwa: i-cascading, stacking, kanye nokuhlanganisa
I-Switch cascading: Ngokuvamile, indlela yokuxhuma esetshenziswa kakhulu i-cascading.I-Cascading ingahlukaniswa ngokusetshenziswa kwezimbobo ezivamile zokukhipha kanye nokusebenzisa izimbobo ze-Uplink ukuze kukhishwe.Vele uxhume amachweba avamile ngezintambo zenethiwekhi.
I-Uplink port cascading iyisixhumi esibonakalayo esikhethekile esinikezwe iswishi ukuze siyixhume embobeni evamile kwenye iswishi.Kufanele kuqashelwe ukuthi akukhona ukuxhumana phakathi kwamachweba amabili we-Uplink.
Ukushintsha ukunqwabelanisa: Le ndlela yokuxhuma ivamise ukusetshenziswa kumanethiwekhi amakhulu naphakathi nendawo, kodwa akuwona wonke amaswishi asekela ukunqwabelana.I-Stacking inezimbobo zokupakisha ezizinikele, ezingabhekwa njengeswishi yonke yokuphatha nokusetshenziswa ngemva kokuxhumeka.Umkhawulokudonsa wokushintsha okustakiwe uphindwe amashumi ejubane lembobo yokushintsha eyodwa.
Kodwa-ke, ukulinganiselwa kwalokhu kuxhumana kubonakala futhi, njengoba kungenakuqoqwa ezindaweni ezide, amaswishi kuphela axhunywe ndawonye angabekwa.
Shintsha iqoqo: Abakhiqizi abahlukene banezinhlelo zokuqalisa ezihlukene zeqoqo, futhi ngokuvamile abakhiqizi basebenzisa izivumelwano zobunikazi ukuze basebenzise iqoqo.Lokhu kunquma ukuthi ubuchwepheshe be-cluster bunemikhawulo yabo.Ukushintsha okuvela kubakhiqizi abahlukene kungenziwa nge-cascade, kodwa akukwazi ukuqoqwa.
Ngakho-ke, indlela ye-cascading ye-switch ilula ukuyisebenzisa, kuphela ipheya elilodwa elisontekile elidingekayo, elingagcini nje ngokusindisa izindleko kodwa ngokuyisisekelo alikhawulelwe ngebanga.Indlela yokunqwabelanisa idinga ukutshalwa kwezimali okukhulu futhi ingaxhunywa kuphela ngebanga elifushane, okwenza kube nzima ukuyisebenzisa.Kodwa indlela yokupakisha inokusebenza okungcono kunendlela ye-cascading, futhi isignali ayiqedi kalula.Ngaphezu kwalokho, ngokusebenzisa indlela yokunqwabelanisa, ukushintsha okuningi kungaphathwa endaweni eyodwa, kube lula kakhulu umthwalo wokuphatha.
