Phakathi kwezinkomba eziningi zokusebenza zokushintshwa kwezimboni, sivame ukubona inkomba "eguquguqukayo".Kusho ukuthini?

Ukuzijwayeza kuphinde kubizwe ngokuthi ukufanisa okuzenzakalelayo kanye nokuxoxisana okuzenzakalelayo.Ngemuva kokuthi ubuchwepheshe be-Ethernet buthuthuke bafinyelela ku-100M isivinini, kunenkinga yokuthi ungahambisana kanjani nemishini yokuqala ye-10M Ethernet.Ubuchwepheshe be-auto-negotiation bakhelwe ukuxazulula le nkinga.

Umsebenzi we-auto-negotiation uvumela idivayisi yenethiwekhi ukuthi idlulisele ulwazi lwemodi yokusebenza elusekelayo iye kolunye uhlangothi lwenethiwekhi futhi yamukele ulwazi oluhambisanayo olungadluliswa olunye uhlangothi.Umsebenzi we-auto-negotiation wenziwa ngokuphelele ukwakheka kwe-chip yesendlalelo esibonakalayo, ngakho-ke ayisebenzisi imilayezo yedatha ezinikele noma ilethe noma iyiphi iphrothokholi yezinga eliphezulu phezulu.

Uma isixhumanisi siqaliswa, iphrothokholi yezingxoxo ezizenzakalelayo ithumela amaphakethe angu-16-bit kudivayisi kontanga futhi ithola amaphakethe afanayo kusukela kudivayisi yontanga.Okuqukethwe kwe-auto-negotiation ikakhulukazi kufaka phakathi isivinini, i-duplex, ukulawula ukugeleza nokunye.Ngakolunye uhlangothi, yazisa indlela yokusebenza yedivayisi yontanga ngokwayo, futhi ngakolunye uhlangothi, ithola indlela yokusebenza yedivayisi yontanga kumlayezo othunyelwe untanga.Izinguquko zezimboni ze-Ru Feichang Technology ziyizinga lokudlulisa elingu-10/100/1000M eliguquguqukayo, kungakhathaliseki ukuthi hlobo luni lwekhadi lenethiwekhi elixhunyiwe, lingasetshenziswa ngokujwayelekile.
