Mwaramutse Basomyi, Muri iyi ngingo tugiye kwiga icyo kugenzura amakosa no kugenzura amakosa.
Muburyo bwo kohereza amakuru, bitewe ningaruka zurusaku kumuyoboro, ibimenyetso byerekana ibimenyetso bishobora kugoreka iyo byoherejwe kubakira, bikavamo amakosa yamakuru. Kugirango wuzuze ibisabwa byateganijwe kuri aya makosa, harasabwa kugenzura amakosa. Ihame ryo kugenzura amakosa ni uko nyuma ya K bits yamakuru yoherejwe, hariho R bits yumubare wuzuye mubiciro byimigabane. Amakuru yakiriwe nuwakiriye akoresha algorithm ihuriweho, kandi ibisubizo bigereranwa nibisubizo byohereje. ikosa. Niba uwakiriye azi ko hari ikosa, ariko akaba atazi ikosa icyo aricyo, hanyuma agasaba koherezwa kubohereje, iyi ngamba yitwa ikosa ryo kumenya; niba uwakiriye azi ko hari ikosa kandi azi ikosa icyo aricyo, ingamba zitwa gukosora amakosa.
(2) Kugenzura ibyiciro
Hariho ubwoko bubiri bwikosa ryo kugenzura: amakosa ya biti namakosa. Ikosa rito ni ikosa rito, 1 iba 0, 0 iba 1; hari amakosa atatu ashoboka yibintu: gutakaza, gusubiramo, hamwe no gutondekanya. Niba hari ikosa rifitanye isano, noneho dukeneye gusaba igisubizo kuva data ihuza urwego kuri seriveri yatanzwe numuyoboro. Ihuza ryamakuru ritanga imirimo itatu yibanze kumurongo wurusobe:
1. Nta byemeza kandi nta serivisi ihuza.
2. Emeza ko nta serivisi ihuza.
3. Serivisi zemejwe zihuza serivisi.
Ibyavuzwe haruguru nubusobanuro bwubumenyi bwa "Error Control" bwazanywe na Shenzhen HDV fotoelectric Technology Co., Ltd. Ibicuruzwa byitumanaho byakozwe na sosiyete: Ibyiciro by'amasomo: moderi ya fibre optique, Ethernet, optique fibre transceiver modules, optique ya fibre optique, SSFP optique module, naSFP optique, n'ibindi.
ONUicyiciro: EPON ONU, AC ONU, fibre optique ONU, CATV ONU, GPON ONU, XPON ONU, n'ibindi.
OLTicyiciro: OLT, GPON OLT, EPON OLT, itumanahoOLT, n'ibindi.
Ibicuruzwa byavuzwe haruguru birashobora gutanga inkunga kubintu bitandukanye byurusobe. Itsinda ryumwuga kandi rikomeye R&D rirashobora gufasha abakiriya bafite ibibazo bya tekiniki, kandi itsinda ryubucuruzi ryatekereje kandi ryumwuga rirashobora gufasha abakiriya kubona serivise nziza mugihe cyo kubanza kugisha inama no gukora nyuma yumusaruro. Murakaza neza kuritwandikire kubibazo byose.
