Guhana ni ijambo rusange ryikoranabuhanga ryohereza amakuru yoherezwa kumurongo uhuye wujuje ibisabwa nibikoresho byintoki cyangwa byikora ukurikije ibisabwa byo kohereza amakuru kumpande zombi zitumanaho.Ukurikije imyanya itandukanye ikora, irashobora kugabanywa mubice bigari byumuyoboro uhuza hamwe nu murongo waho uhuza.Guhindura imiyoboro yagutse ni ubwoko bwibikoresho byuzuza amakuru yo guhanahana amakuru muri sisitemu yitumanaho.None, ni ubuhe buryo bwo kohereza bwa switch?

Uburyo bwo kohereza:

1. Guhinduranya
2. Guhindura ububiko-na-Imbere
3. Guhindura ibice

Byaba ari byoherejwe mu buryo butaziguye cyangwa ububiko-bwohereza ni uburyo bubiri bwo kohereza, kandi ingamba zabo zo kohereza zishingiye ku cyerekezo MAC (DMAC), nta tandukaniro riri hagati yuburyo bubiri bwo kohereza kuri iyi ngingo.
Itandukaniro rinini hagati yabo ni mugihe bakorana no kohereza, ni ukuvuga, uburyo switch ikorana isano iri hagati yo kwakira no kohereza inzira yamakuru.

Ubwoko bwo kohereza:
1. Kata
Guhinduranya-kunyuze kuri Ethernet birashobora kumvikana nkumurongo wa matrix ya terefone ya terefone yambukiranya kandi itambitse hagati ya buri cyambu.Iyo ibonye paki yamakuru kuri port yinjiza, iragenzura umutwe wapaki, ikabona aderesi yerekanwe aho ipaki, igatangira imbonerahamwe yimbere yimbere ikareba hanyuma ikayihindura mubyambu bisohoka, ihuza kumasangano yinjira n'ibisohoka, kandi ihererekanya amakuru yapakiye kuri port ijyanye no kumenya imikorere yo guhinduranya.Kubera ko nta bubiko busabwa, gutinda ni bito cyane kandi guhana byihuta cyane, ninyungu zayo.
Ikibi cyayo nuko kuberako ibikubiye mububiko bwamakuru atabitswe na enterineti ya Ethernet, ntishobora kugenzura niba paki yamakuru yatanzwe atariyo, kandi ntishobora gutanga ubushobozi bwo kumenya amakosa.Kuberako nta buffer, ibyinjira / ibisohoka ibyambu bifite umuvuduko utandukanye ntibishobora guhuzwa neza, kandi paki ziratakara byoroshye.

2. Kubika no Kujya imbere (Ububiko; Imbere)
Uburyo bwo kubika-no-imbere nuburyo bukoreshwa cyane murwego rwimiyoboro ya mudasobwa.Igenzura amakuru yipaki yicyambu cyinjira, ikuramo aderesi yerekanirwamo amakuru yamakuru nyuma yo gutunganya ikosa ryamakosa, ikayihindura icyambu gisohoka kugirango yohereze paki binyuze mumeza yo gushakisha.Kubera iyo mpamvu, uburyo bwo kubika-no-imbere butinda cyane mugutunganya amakuru, aribwo bugaragara, ariko irashobora gukora amakosa yo gutahura kumapaki yamakuru yinjira muri enterineti kandi igateza imbere imikorere yurusobe.Ni ngombwa cyane cyane ko ishobora gushyigikira ihinduka hagati yicyambu cyihuta kandi igakomeza ubufatanye hagati yicyambu cyihuta nicyambu gito.

3. Igice cyubusa
Iki ni igisubizo hagati yabiri yambere.Igenzura niba uburebure bwamakuru paki buhagije kuri 64 bytes, niba butarenze 64 bytes, bivuze ko ari paki yimpimbano, hanyuma ujugunye paki;niba irenze 64 bytes, noneho ohereza paki.Ubu buryo kandi ntabwo butanga igenzura ryamakuru.Umuvuduko wacyo wo gutunganya amakuru yihuta kuruta kubika-no-imbere, ariko gahoro kuruta kugororoka.
Byaba ari ugutumiza mu buryo butaziguye cyangwa kubika ibicuruzwa, ni uburyo bwo kohereza ibice bibiri, kandi ingamba zabo zo kohereza zishingiye ku cyerekezo MAC (DMAC).Nta tandukaniro riri hagati yuburyo bubiri bwo kohereza kuriyi ngingo.Itandukaniro rinini hagati yabo nigihe bakorana no kohereza, ni ukuvuga, uburyo switch ikora isano iri hagati yuburyo bwo kwakira no kohereza inzira yamakuru.
