Xeem tag nrho bandwidth uas txhua qhov chaw nres nkoj ntawm qhov hloov pauv tuaj yeem muab tau. Xam cov naj npawb ntawm cov chaw nres nkojQhov sib thooj qhov chaw nres nkoj2 (tag nrho-duplex hom) Yog tias tag nrho bandwidth ≤ nominal backplane bandwidth, ces qhov backplane bandwidth yog linear.
Dab tsi yog qhov rov qab nrawm ntawm qhov hloov pauv?
Lub peev xwm rov qab yuav qhia tias muaj bandwidth ntau npaum li cas rau cov ntaub ntawv ntawm cov modules. Yog li qhov siab tshaj plaws ntawm 8.8 Gbps cov ntaub ntawv tuaj yeem ntws ntawm cov modules / lossis mus rau CPU thiab rov qab. Yog li qhov no yog ib qho ntawm cov khoom cuam tshuam rau kev ua haujlwm ntawm lub cuab yeej.
Dab tsi yog backplane hauv kev hloov?
Ib lub dav hlau rov qab yog lub voj voog uas muab kev sib txuas ntawm cov qauv sib txawv ntawm kev hloov pauv lossis kev hloov khoom siv. … Rau kev saib xyuas thiab kev tswj xyuas lub network, lub peev xwm rov qab (lossis backplane bandwidth) yog lub tswv yim tseem ceeb heev. Backplane muaj peev xwm ua raws li lub hau ntawm qhov siab tshaj plaws ntawm cov khoom siv network.
Yuav hloov bandwidth xam li cas?
The switching peev xwm ntawm qhov hloov=Tus naj npawb ntawm cov chaw nres nkojTus nqi ntawm qhov chaw nres nkoj 2 (full-duplex). Piv txwv li, lub peev xwm hloov ntawm 24-chaw nres nkoj 100M hloov yog=241002=4.8Gbps.
Koj ua li cas xam tus nqi xa mus rau ntawm qhov hloov?
Forwarding Rate =Chaw nres nkoj tus lejChaw nres nkoj Ceev / 10001.488Mpps. 8100/10001.488Mpps=1.2Mpps/S. Yog tias tus nqi xa mus tsawg dua qhov ntawd, qhovhom hloov pauv tsis yog kab nrawm.
