Siyini isiphepho sokusakaza?

Isiphepho sokusakaza sisho nje ukuthi lapho idatha yokusakaza ikhukhula inethiwekhi futhi ayikwazi ukucutshungulwa, ithatha inani elikhulu lomkhawulokudonsa wenethiwekhi, okuholela ekungakwazini kwezinsizakalo ezijwayelekile ukusebenza, noma ngisho nokukhubazeka okuphelele, futhi "isiphepho sokusakaza" senzeka.Uhlaka lwedatha noma iphakethe lidluliselwa endaweni ngayinye engxenyeni yenethiwekhi yendawo (echazwe isizinda sokusakaza) iwukusakazwa;ngenxa yezinkinga zokuklama nokuxhumeka kwe-topology yenethiwekhi, noma ezinye izizathu, ukusakazwa kukopishwa ngenani elikhulu ngaphakathi kwengxenye yenethiwekhi, ukusabalalisa uhlaka lwedatha, Lokhu kuholela ekulimazeni kokusebenza kwenethiwekhi ngisho nokukhubazeka kwenethiwekhi, okubizwa ngokuthi. isivunguvungu sokusakaza.  

Iyini indandatho ye-Ethernet?

Iringi ye-Ethernet (evame ukwaziwa ngokuthi inethiwekhi eyindandatho) i-topology eyindandatho ehlanganisa iqembu lamanodi e-Ethernet athobelana ne-IEEE 802.1, inodi ngayinye ixhumana namanye amanodi amabili ngokusebenzisa imbobo yokungena kweMedia Access engu-802.3 (MAC) esekwe ku-802.3.I-Ethernet MAC ingathwalwa obunye ubuchwepheshe bongqimba lwesevisi (obufana ne-SDHVC, i-Ethernet pseudowire ye-MPLS, njll.), futhi wonke ama-node angaxhumana ngokuqondile noma ngokungaqondile.
