Amaswishi endabuko athuthukiswe esuka emabhulohweni futhi ayengowesendlalelo sesibili se-OSI, okokusebenza kongqimba lwedatha.Ikhuluma ngokwekheli le-MAC, ikhetha umzila ngetafula lesiteshi, futhi ukusungulwa nokugcinwa kwetafula lesiteshi kwenziwa ngokuzenzakalelayo amaswishi eCISCO Cisco.I-router ingeyesendlalelo sesithathu se-OSI, okungukuthi, idivayisi yesendlalelo senethiwekhi.Ikhuluma ngokwekheli le-IP futhi ikhiqizwa ngephrothokholi yomzila wethebula lomzila.Inzuzo enkulu yokushintshwa kwe-Gigabit enezingqimba ezintathu kuyashesha.Ngoba iswishi idinga kuphela ukukhomba ikheli le-MAC kuhlaka, ikhiqiza ngokuqondile futhi ikhethe i-algorithm yembobo yokudlulisela ngokusekelwe ekhelini le-MAC.I-algorithm ilula futhi kulula ukuyisebenzisa nge-ASIC, ngakho-ke ijubane lokudlulisela liphezulu kakhulu.Kodwa indlela yokusebenza ye-switch nayo iletha izinkinga ezithile.
1. Iluphu: Ngokusho kwe-Huanet shintsha ikheli lokufunda kanye ne-algorithm yokusungulwa kwetafula lesiteshi, amalophu awavunyelwe phakathi kokushintsha.Uma sekukhona iluphu, i-algorithm yesihlahla esinwebekayo kufanele iqalwe ukuze kuvinjwe imbobo ekhiqiza iluphu.Iphrothokholi yomzila yerutha ayinayo le nkinga.Kungaba khona izindlela eziningi phakathi kwamarutha ukuze kulinganiswe umthwalo futhi kuthuthukiswe ukwethembeka.
2. Ukugxiliswa komthwalo:Kungaba nesiteshi esisodwa kuphela phakathi kokushintshwa kwe-Huanet, ukuze ulwazi lugxile kusixhumanisi esisodwa sokuxhumana, futhi ukusabalalisa okunamandla akunakwenzeka ukulinganisa umthwalo.I-algorithm yephrothokholi yomzila womzila ingakugwema lokhu.I-algorithm ye-OSPF yomzila wephrothokholi ayikwazi nje ukukhiqiza imizila eminingi, kodwa futhi ikhethe imizila engcono kakhulu yezinhlelo zokusebenza ezahlukene zenethiwekhi.
3. Ukulawula ukusakaza:Ukushintsha kwe-Huanet kunganciphisa kuphela isizinda sokungqubuzana, kodwa hhayi isizinda sokusakaza.Yonke inethiwekhi eshintshiwe iyisizinda esikhulu sokusakaza, futhi imilayezo esakazwayo isakazwa kuyo yonke inethiwekhi eshintshiwe.Irutha ingahlukanisa isizinda sokusakaza, futhi amaphakethe okusakaza awakwazi ukuqhubeka nokusakaza ngomzila.
