Menene bandwidth na baya-baya da ƙimar isar da fakiti?-01

bandwidth na baya:

Har ila yau ana kiran bandwidth na baya-baya ƙarfin baya, wanda aka bayyana a matsayin matsakaicin adadin bayanai da za a iya sarrafa ta na'urar dubawa, katin dubawa da bas ɗin bayanai na sauyawa.Yana wakiltar iyawar musanyar bayanai gaba ɗaya, a cikin Gbps, wanda ake kira bandwidth mai sauyawa.Yawancin lokaci, bandwidth na baya da za mu iya samun damar jeri daga ƴan Gbps zuwa ƴan Gbps ɗari kaɗan.

Yawan tura fakiti:

Matsakaicin isar da fakiti na maɓalli, wanda kuma aka sani da tashar tashar jiragen ruwa, shine ikon mai canzawa zuwa tura fakiti akan wata tashar jiragen ruwa, yawanci a cikin pps, wanda ake kira fakiti a sakan daya, wanda shine adadin fakitin da ake turawa a cikin daƙiƙa guda.

Ga hanyar sadarwa gama gari: Ana watsa bayanan cibiyar sadarwa ta cikin fakitin bayanai, waɗanda suka ƙunshi bayanan da aka watsa, da manyan kantuna, da gibin firam.Matsakaicin abin da ake buƙata don fakitin bayanai a cikin hanyar sadarwar shine 64 bytes, inda 64 bytes tsarkakakku ne.Ƙara ɓangarorin firam 8-byte da tazarar firam 12-byte, ƙaramin fakiti a cikin hanyar sadarwa shine 84 bytes.

Don haka lokacin da cikakken duplex gigabit interface ya kai saurin layi, ƙimar isar da fakitin shine

=1000Mbps/((64+8+12)* 8bit)

= 1.488Mpps.

Alakar da ke tsakanin su biyu:

Rukunin bandwidth na jirgin baya na juyawa yana wakiltar jimillar ƙarfin musayar bayanai na maɓalli kuma yana da mahimmancin nuni na ƙimar fakitin turawa.Don haka ana iya fahimtar jirgin baya a matsayin motar bas na kwamfuta, kuma idan jirgin baya ya fi girma, ƙarfin sarrafa bayanai yana da ƙarfi, wanda ke nufin haɓaka ƙimar fakitin.
