noma imodeli yereferensi ye-OSI, iswishi isebenza kungqimba lwesibili lwale modeli, isendlalelo sesixhumanisi sedatha.Njengoba kuboniswe emfanekisweni olandelayo, ukushintshwa kunamachweba ayisishiyagalombili.Uma idivayisi ixhunywe kuswishi nge-RJ45, i-chip eyinhloko yeswishi izohlonza izimbobo ezixhunywe kukhebuli yenethiwekhi, futhi ukuxhumeka kuba yimpumelelo.Ikheli le-mac ledivayisi exhunyiwe lihambisana nembobo.Uma zonke izimbobo eziyisishiyagalombili zixhunyiwe, okuyinhloko kwangaphakathi kungakha ithebula le-MAC elinazo zonke izimbobo.Ekuxhumaneni kwembobo okulandelayo, lapho idivayisi idlulisela ulwazi, izokhipha iphakethe ledatha elinomthombo we-mac kanye ne-mac eqondiwe.Ngemuva kokuthi iphakethe ledatha lifinyelela ku-master control, lingathumela ngokushesha iphakethe ledatha kudivayisi enekheli le-mac elihambisana nethebula le-mac elimisiwe, ukuze kuzuzwe ukuxhumana phakathi kwamadivaysi.Ngaphezu kwalokho, amaphakethe athunyelwe ekhelini le-MAC azothunyelwa kuphela ezimbobeni zawo ezihambisanayo, hhayi zonke izimbobo.Ngakho-ke, ukushintshwa kungasetshenziswa ukuhlukanisa ukusakazwa kwesendlalelo sesixhumanisi sedatha, okungukuthi, isizinda sokungqubuzana, kodwa asikwazi ukuhlukanisa ukusakazwa kwesendlalelo senethiwekhi, okungukuthi, isizinda sokusakaza.
Tushintsha unebhasi elibuyela emuva elinomkhawulokudonsa ophezulu kanye ne-matrix yokushintsha yangaphakathi.Zonke izimbobo zokushintsha zinamathiselwe kuleli bhasi elibuyela emuva.Ngemuva kokuthi isifunda sokulawula sithole iphakethe ledatha, imbobo yokucubungula izobheka ithebula lokuqhathanisa ikheli kumemori ukuze inqume ukuthi iyiphi imbobo i-NIC (ikhadi lenethiwekhi) yendawo okuyiwa kuyo i-MAC (ikheli le-hardware yekhadi lenethiwekhi) enamathiselwe kuyo.Iphakethe ledatha lizodluliselwa ngokushesha endaweni okuyiwa kuyo nge-matrix yokushintshisana yangaphakathi.Uma i-MAC okuyiwa kuyo ingekho, izosakazwa kuwo wonke amachweba, Ngemva kokuthola impendulo yechweba, ukushintshaniswa "kuzofunda" ikheli elisha le-MAC futhi lilengeze kuthebula lekheli langaphakathi le-MAC.Iswishi ingase futhi "ihlukanise" inethiwekhi.Iswishi ivumela kuphela ithrafikhi yenethiwekhi edingekayo ukuthi idlule ekushintsheni ngokuyiqhathanisa nethebula lekheli le-IP.Ngokuhlunga nokudluliswa kweswishi, isizinda sokungqubuzana singancishiswa sibe usayizi olawulekayo.
Okungenhla kuyincazelo yesimiso sokusebenza sokushintsha okuhlinzekwe nguI-Shenzhen HDV Phoelectron Technology Co., Ltd.ngethemba ukuthi lesi sihloko singakusiza ukukhulisa ulwazi lwakho.Ngaphandle kwalesi sihloko uma ufuna inkampani enhle yabakhiqizi bemishini yokuxhumana ye-fiber ongase uyicabangeleMayelana NATHI.
