Yintoni isaqhwithi sosasazo?

Isivunguvungu sosasazo sithetha nje ukuba xa idatha yosasazo ikhukhula inethiwekhi kwaye ayikwazi ukucutshungulwa, ithatha inani elikhulu le-bandwidth yenethiwekhi, okubangelwa ukungakwazi kweenkonzo eziqhelekileyo ukuqhuba, okanye ukukhubazeka okupheleleyo, kwaye "isaqhwithi sokusasaza" kwenzeka.Isakhelo sedatha okanye ipakethi idluliselwa kwi-node nganye kwicandelo lenethiwekhi yendawo (echazwe yi-domain yosasazo) lusasazo;ngenxa yoyilo kunye neengxaki zoqhagamshelwano lwe-topology yenethiwekhi, okanye ezinye izizathu, usasazo lukhutshelwa inani elikhulu ngaphakathi kwecandelo lothungelwano, lisasaza isakhelo sedatha, Oku kukhokelela ekuthotyweni komsebenzi womnatha kunye nokukhubazeka kwenethiwekhi, ebizwa ngokuba isaqhwithi sosasazo.  

Yintoni umsesane we-Ethernet?

Iringi ye-Ethernet (eyaziwa ngokuba yi-network ye-ring) yi-topology ye-ring equkethe iqela le-IEEE 802.1 ehambelanayo ye-Ethernet nodes, i-node nganye inxibelelana namanye ama-nodes amabini nge-802.3 Media Access Control (MAC) esekelwe kwi-ring port.I-Ethernet MAC inokuthwalwa bubunye ubuchwephesha bomgangatho wenkonzo (njenge-SDHVC, i-Ethernet pseudowire yeMPLS, njl.), kwaye zonke iinodi ziyakwazi ukunxibelelana ngokuthe ngqo okanye ngokungathanga ngqo.
