Nakuba zombili zisetshenziselwa ukushintsha inethiwekhi, kunomehluko ekusebenzeni.

Umehluko 1:Umthwalo kanye ne-subnetting kuhlukile.Kungaba khona indlela eyodwa kuphela phakathi kwamaswishi e-Ethernet, ukuze ulwazi lugxile kusixhumanisi esisodwa sokuxhumana futhi alukwazi ukwabiwa ngamandla ukuze kulinganiswe umthwalo.I-algorithm yephrothokholi yomzila womzila ingakugwema lokhu.I-algorithm ye-OSPF yomzila wephrothokholi ayikwazi nje ukukhiqiza imizila eminingi, kodwa futhi ikhethe imizila ehlukene efanele yezinhlelo zokusebenza zenethiwekhi ezahlukene.Kungabonakala ukuthi umthwalo we-router mkhulu kakhulu kunowokushintsha kwe-Ethernet.Amaswishi e-Ethernet angabona kuphela amakheli e-MAC.Amakheli e-MAC angamakheli wendawo futhi anesakhiwo sekheli eliyisicaba, ngakho-ke i-subnetting ayikwazi ukusekelwe kumakheli e-MAC.I-router ikhomba ikheli le-IP, elinikezwa umlawuli wenethiwekhi.Ikheli elinengqondo futhi ikheli le-IP linesakhiwo sokulandelana.Ihlukaniswe ngezinombolo zenethiwekhi nezinombolo zokusingatha, ezingasetshenziswa kalula ukuhlukanisa ama-subnet.Umsebenzi oyinhloko we-router ukusebenzisa ukuxhuma kumanethiwekhi ahlukene

Umehluko 2:Ukulawulwa kwemidiya nokusakaza kuhlukile.Ukushintsha kwe-Ethernet kunganciphisa kuphela isizinda sokushayisana, kodwa hhayi isizinda sokusakaza.Yonke inethiwekhi eshintshiwe iyisizinda esikhulu sokusakaza, futhi amaphakethe okusakaza asatshalaliswa kuyo yonke inethiwekhi eshintshiwe.Irutha ingakwazi ukuhlukanisa isizinda sokusakaza, futhi amaphakethe okusakaza awakwazi ukuqhubeka nokusakaza ngomzila.Kungabonakala ukuthi ububanzi bokulawulwa kokusakaza kwama-switch e-Ethernet bukhulu kakhulu kunama-routers, futhi ububanzi bokulawulwa kokusakaza kwama-routers busencane uma kuqhathaniswa.Njengedivayisi yokuvala ibhuloho, ukushintshwa kwe-Ethernet kungaphinda kuqedele ukuguqulwa phakathi kwezingqimba zesixhumanisi ezihlukene nezendlalelo ezibonakalayo, kodwa le nqubo yokuguqula iyinkimbinkimbi futhi ayifanele ukuqaliswa kwe-ASIC, okuzonciphisa nakanjani isivinini sokudlulisela iswishi.
