Niba dukoresheje imvugo ngereranyo ikunze kugaragara, imikorere ya switch ni ukugabanya icyambu cyumuyoboro mubyambu byinshi kugirango wohereze amakuru, kimwe no kuvoma amazi kumuyoboro umwe wamazi akajya mumiyoboro myinshi yabantu benshi bakoresha.
"Amazi atemba" yanduzwa murusobe ni data, agizwe nudupapuro twihariye.Guhindura bigomba gutunganya buri paki, bityo umurongo mugari wa switch backplane nubushobozi ntarengwa bwo guhanahana amakuru, kandi igipimo cyo kohereza paki nubushobozi bwo gutunganya kwakira amakuru hanyuma ukayohereza.
Ninini agaciro ka switch backplane bandwidth hamwe na packet yohereza imbere, niko imbaraga zogutunganya amakuru, hamwe nigiciro cyinshi cya switch.
Umuyoboro mugari:
Umuyoboro mugari nanone witwa ubushobozi bwinyuma, bisobanurwa nkumubare ntarengwa wamakuru ashobora gukoreshwa nigikoresho cyo gutunganya, ikarita yimbere hamwe na bisi ya data ya switch.Yerekana muri rusange ubushobozi bwo guhanahana amakuru yo guhinduranya, muri Gbps, bita guhinduranya umurongo.Mubisanzwe, umugongo winyuma dushobora kubona intera kuva kuri Gbps nkeya kugeza kuri Gbps magana.
Igipimo cyo kohereza paki:
Igipimo cyo kohereza igipimo cya switch, kizwi kandi nk'icyambu cyinjira, ni ubushobozi bwo guhinduranya ujya imbere udupaki ku cyambu runaka, ubusanzwe muri pps, bita paki ku isegonda, niwo mubare w'ipaki yoherejwe ku isegonda.
Hano hari urusobe rusanzwe: Urusobe rwamakuru rwoherezwa binyuze mumapaki yamakuru, agizwe namakuru yoherejwe, imitwe yimitwe, hamwe nicyuho.Ibisabwa byibuze kuri paki yamakuru murusobe ni 64 bytes, aho 64 bytes namakuru meza.Ongeraho 8-byte ikadiri yumutwe hamwe na 12-byte ikadiri, paki ntoya murusobe ni 84 bytes.
Iyo rero duplex yuzuye ya gigabit igera kumurongo wihuta, igipimo cyo kohereza ni
= 1000Mbps / ((64 + 8 + 12) * 8bit)
= 1.488Mpps.
Isano iri hagati yombi:
Umuyoboro mugari wa switch backplane yerekana ubushobozi bwuzuye bwo guhanahana amakuru ya switch kandi ni nacyo kimenyetso cyerekana igipimo cyo kohereza ibicuruzwa.Indege yinyuma rero irashobora kumvikana nka bisi ya mudasobwa, kandi hejuru yindege, niko imbaraga zayo zo gutunganya amakuru, bivuze ko igipimo cyo kohereza ibicuruzwa kiri hejuru.
