Utshintshiselwano lutshintsha ngeendlela ezintathu ezilandelayo

1) Ngokuthe ngqo:

Ukutshintsha kwe-Ethernet ngokuthe ngqo kunokuqondwa njengomgca wefowuni ye-matrix yefowuni kunye ne-crossover phakathi kwamazibuko.Xa ibona ipakethe yedatha kwizibuko logalelo, ijonga iheader yepakethe yepakethi, ifumana idilesi yendawo yokufikela yepakethi, iqala itafile yokukhangela eguquguqukayo yangaphakathi ukuyiguqulela kwizibuko lemveliso ehambelanayo, idibanisa kwindawo yokuhlangana yegalelo kwaye imveliso, kwaye igqithisa ipakethe yedata ngqo kwi Izibuko ehambelanayo iqonda umsebenzi wokutshintsha.

2) Gcina nangaphambili:

Indlela yogcino-phambili yeyona ndlela isetyenziswa kakhulu kwindawo yothungelwano lwekhompyuter.Igcina kuqala iipakethi zedatha ye-port yongeniso, kwaye yenza i-CRC (Cyclic Redundancy Check) khangela.Emva kokucubungula iipakethi zempazamo, ithatha idilesi yendawo yepakethi yedatha, kwaye iyiguqulele kwi-port yemveliso ngokusebenzisa itafile yokujonga ukuthumela ipakethi.

3) Ukwahlulwa kweqhekeza:

Esi sisisombululo phakathi kwezi zibini zokuqala.Ijonga ukuba ubude bepakethi yedatha yanele ukuya kuma-bytes angama-64.Ukuba ingaphantsi kwe-64 bytes, ithetha ukuba yipakethi yobuxoki, kwaye ipakethi ilahlwe;ukuba ingaphezulu kwe-64 bytes, ipakethi iyathunyelwa.Le ndlela nayo ayinikezeli ukuqinisekiswa kwedatha.Isantya sokucwangcisa idatha sikhawuleza kunokugcina-kunye-phambili, kodwa sicotha kunokusika.
