Ihinduranya ry'amakuru mu buryo butatu bukurikira

1) Kunyura mu buryo butaziguye:

Guhinduranya Ethernet mu buryo butaziguye bishobora kumvikana nk'ihinduranya rya telefoni rikoresha umurongo umwe rifite aho rihurira hagati y'aho rihurira. Iyo ribonye paki y'amakuru kuri poritiyo y'injira, rigenzura umutwe w'ipaki, rigafata aderesi y'aho rijya, rigatangiza imbonerahamwe y'ishakisha ry'imbere kugira ngo rihindurwemo poritiyo y'isohoka ijyanye nayo, rigahuza aho ishyirwa n'isohoka bihurira, hanyuma rigahita ryohereza paki y'amakuru kuri poritiyo y'isohoka ijyanye nayo. Poritiyo y'amakuru ijyanye nayo ikora akazi ko guhindura.

2) Bika hanyuma ushyire hanze:

Uburyo bwo kubika no kohereza amakuru ni bwo bukoreshwa cyane mu bijyanye n'imiyoboro ya mudasobwa. Bubanza kubika amakuru y'aho umuntu akorera, hanyuma bugakora igenzura rya CRC (Cyclic Redundancy Check). Nyuma yo gutunganya amakosa y'amakuru, bukuraho aderesi y'aho umuntu akorera amakuru y'amakuru, bukayihindura aho umuntu akorera binyuze mu mbonerahamwe yo gushakisha kugira ngo yohereze ayo makuru.

3) Gutandukanya ibice:

Iki ni igisubizo kiri hagati y’ibi bibiri bya mbere. Kigenzura niba uburebure bw’ipaki y’amakuru buhagije kuri byte 64. Iyo iri munsi ya byte 64, bivuze ko ari ipaki y’impimbano, hanyuma ipaki ikajugunywa; iyo irengeje byte 64, ipaki yoherezwa. Ubu buryo ntibutanga kandi kwemeza amakuru. Umuvuduko wayo wo gutunganya amakuru wihuta kurusha kubika no kohereza amakuru, ariko ugenda buhoro kurusha gukata amakuru.
