Inkqubo yokubeka iliso yothungelwano ithatha indawo epheleleyo kwiprojekthi yokhuseleko. Kwi-high-definition network network monitoring system, kuhlala kukho izinto ezifana nokulibaziseka kwemifanekiso kunye nomkhenkce. Kukho izizathu ezininzi zezi ziganeko, kodwa kwiimeko ezininzi, ukucwangciswa kokutshintsha akukho ngqiqweni ngokwaneleyo, kubangele i-bandwidth eyaneleyo. Ukutshintsha sisixhobo esiyimfuneko kuyo yonke inkqubo. Nokuba iqwalaselwe ngokuchanekileyo okanye ayichaphazeli ngokuthe ngqo uzinzo lwamva lwenkqubo yokubeka iliso kuthungelwano.

Xa ukhetha iswitshi, kufuneka ukhethe kwi-bandwidth kunye nereyithi yokuthumela ipakethe. I-backplane bandwidth yimali eninzi yedatha enokuthi iphathwe phakathi kweprosesa ye-switch interface okanye ikhadi le-interface kunye nebhasi yedatha. Iphawula umthamo wotshintshiselwano lwedatha iyonke yokutshintsha, ukuphakama kwebhanwidth ye-backplane, kunamandla amandla okwenza idatha. Izinga lokuthunyelwa kwepakethi likwabizwa ngokuba yi-port throughput, ebhekisa kwisakhono somzila wokudlulisa iipakethi zedatha kwizibuko. Okukhona iphezulu ireyithi yokuthumela ipakethe, kungcono.

Ngokubhekiselele kwi-topology yenethiwekhi, inkqubo yokujonga ividiyo yenethiwekhi ephakathi kunye nephezulu-inkcazo ephezulu kufuneka yamkele i-architecture yenethiwekhi enemigangatho emithathu: umaleko wokufikelela, umaleko wokuhlangana, kunye nomgangatho ongundoqo.

Indlela yokukhethautshintsho umaleko wofikelelo?
Ukutshintshela umaleko wokufikelela ikakhulu kuqhagamshelwe kumnatha wangaphambili wekhamera yenkcazo ephezulu kwaye iqhagamshelwe kwi-aggregation switch. Ngokusekelwe kumzila wekhowudi ye-4M yeekhamera zenethiwekhi ye-1080P, zingaphi iziteshi zeekhamera zenethiwekhi ze-1080P ezinokudibaniswa kwi-100M enye yokufikelela kwi-port?

I-bandwidth yangempela yeenguqu zethu ezisetyenziswa ngokuqhelekileyo yi-50% -70% yexabiso lethiyori, ngoko ke i-bandwidth yangempela ye-100M port yi-50M-70M. 4M * 12 = 48M, ngoko ke kucetyiswa ukuba enye i-100M yokufikelela kwi-switch inokudibanisa kubuninzi beekhamera zenethiwekhi ze-12 1080P. Ngexesha elifanayo, ngokuqwalasela ukuba i-monitor network monitoring ithatha i-encoding eguquguqukayo, ixabiso lencopho yekhowudi yekhamera inokudlula i-4M ye-bandwidth, kunye noyilo lwe-bandwidth redundancy luyaqwalaselwa. Ngoko ke, kungcono xa ukutshintshwa kokufikelela kwe-100M kulawulwa ngaphakathi kweeyunithi ze-8, kwaye ngaphezu kweeyunithi ze-8 zinconywa. Izibuko leGigabit. Kwezinye iinkqubo zokubeka iliso kwinethiwekhi ye-ultra-high-definition, ukwenzela ukuba kuqinisekiswe imifanekiso yevidiyo ephezulu kunye nokuthembeka okuphezulu kokuhanjiswa kwedatha, umgca wokufikelela unokukhetha ngokuthe ngqo ukutshintshwa kwe-Gigabit epheleleyo.

Unokukhetha njani iswitshi yomaleko odityanisiweyo?

Utshintsho lwe-aggregation layer luqhagamshelwe kwi-switch access layer kunye ne-core switch ye-uplink monitoring center. Ukusebenza kuphezulu kunokutshintsha kokufikelela. Ngaphantsi kweemeko eziqhelekileyo, utshintsho lokudibanisa kufuneka lukhethe utshintsho lwe-Layer 2 kunye ne-gigabit upload port. I-100M port ye-switch ixhunyiwe kwi-switch, kwaye i-port ye-Gigabit ixhunyiwe kwi-core switch yeziko lokubeka iliso. Inani lee-interfaces kwi-aggregation switch kufuneka ilawulwe ngaphakathi kwe-30. Kusabalwa ngokusekelwe kwikhowudi ye-4M yomzila weekhamera zenethiwekhi ze-1080P. Utshintsho ngalunye lokufikelela kwinqanaba elingaphambili lineekhamera zenethiwekhi ze-6 1080P, kunye ne-aggregation switch iqhagamshelwe kwi-5 yokufikelela kwi-switch switch. I-bandwidth epheleleyo ye-aggregation switch yi-4M * 6 * 5 = 120M, ngoko i-cascade port ye-aggregation switch kunye ne-core switch kufuneka ibe yi-gigabit port.

Indlela yokukhetha iswitshi engundoqo?

I-core switch switch idityaniswe ikakhulu kunye ne-aggregation layer, iqonga lokubeka iliso levidiyo ye-uplink, iseva yokugcina, i-matrix yedijithali kunye nezinye izixhobo, ezingundoqo kuyo yonke inkqubo yokujonga inethiwekhi ephezulu. kufuneka uqwalasele umthamo we-bandwidth yenkqubo yonke kunye nendlela yokuqwalasela i-core layer switch ngokungafanelekanga, eya kubangela ukuba isikrini sevidiyo singaphumeleli ukubonisa kakuhle.ngoko, iziko lokubeka iliso. icebisa ukuba ukhethe undoqo wegigabit opheleleyo. Ukuba kukho amanqaku amaninzi, iiVLAN kufuneka zihlulwe, kwaye i-switch ye-Gigabit engundoqo enemigangatho emithathu kufuneka ikhethwe. Inkqubo enkulu yokucupha eneekhamera ezingaphezu kwe-150 kufuneka ithathele ingqalelo i-10 ye-Gigabit core switch.

Amanqaku aphambili okhetho lokutshintsha
Xa ukhetha ukutshintshela uhlolo lwevidiyo kwinethiwekhi yendawo yendawo, ngenxa yokuba uxinzelelo oluphambili lukwi-aggregation layer switch, i-aggregation layer switch kufuneka ithwale uxinzelelo lokubeka iliso kunye nokugcinwa kwetrafikhi kunye noxinzelelo lokujonga ixesha lokwenyani kunye nokufowuna. ukubeka esweni. Ke ngoko, kubaluleke kakhulu ukukhetha iswitshi yokudibanisa esebenzayo. Kunconywa ukuba ukhethe i-gigabit elawulwayo yokutshintsha, enokuyilungisa inethiwekhi, ikhulise kwaye ikhulise izinga lokusetyenziswa kwe-bandwidth, kwaye uqinisekise ukuhanjiswa ngokukhawuleza.

Ukulumkela
Ukuba ukhetha ulawulo lokutshintsha olulawulwa kwiWebhu, kuya kuba lula ngakumbi. Kungcono ukhethe ukutshintshwa kokunciphisa isantya, kwaye xa ukhetha ukutshintsha kunye ne-cache enkulu, ngexesha elifanayo, inkqubo yokubeka iliso yenethiwekhi idinga ukuzinza okuphezulu kunye nokusebenza kwexesha langempela, kwaye indawo yokusebenza yezixhobo inzima kwaye inzima, ngoko ke. ukukhuselwa Ukuhanjiswa okuzinzileyo kunye nokusebenzayo kwedatha yenkqubo, kuyacetyiswa ukuba ukhethe iimveliso zokutshintsha kwe-Ethernet yeshishini kunye nokusebenza okuphezulu kweshishini kunye nokuzinza okuhle.
