Ukukhawuleza nokukhuseleko zimbini zeenzuzo ze-SONET
I-SONET yitheknoloji yocwecwe yocwecwe yendalo yenzelwe ukuthwala iindleko ezinkulu zendlela yokuhamba kwimizila emide kwi- fiber optic cabling . I-SONET yayiyilwe yenziwe yi-American National Standards Institute kwi-Intanethi ye-US yomnxeba woluntu phakathi ne-1980. Lo mgaqo-nkqubo wokunxibelelana kwedatha yedijithali uhambisa iifayile ezininzi kwixesha elifanayo.
Iimpawu zeSonet
I-SONET inempawu eziliqela ezenza ukuba kubonakale, kubandakanywa:
- I-SONET idinga izixhobo ezingaphantsi kweminye iprotocol kwaye inikezela ukunyaniseka kwenethiwekhi.
- I-SONET ichaza imilinganiselo ecacileyo yokusebenzisana phakathi kwemveliso yabathengisi abahlukeneyo.
- I-SONET inokuthwala phantse nayiphi na inkqubo ephakamileyo ye-IP kuquka ne-IP.
- I-SONET ibandakanya ukuxhaswa kwenkxaso ekwenzeni lula ukuphathwa nokugcinwa.
- ISONET isekela zonke iintlobo zezithuthi kuquka ilizwi, idatha kunye nevidiyo.
- I-SONET inikeza ukhuseleko oluphakamileyo kunezinye iiprotoksi.
Ukungahambi kakuhle kweSONET yindleko ephezulu.
I-SONET isetyenziswa ngokubanzi kumanethiwekhi athungathayo. Kufunyenwe kwakhona kwiikampus nakwii-airport.
Ukusebenza
ISONET yenza ngokukhawuleza kakhulu. Kwizinga lokubonisa isiseko, elibizwa ngokuba ngu-STS-1, i-SONET isekela i-51.84 Mbps. Inqanaba elilandelayo leSONET lokubonisa, i-STS-3, isekela kathathu ububanzi bomda, okanye 155.52 Mbps. Amanqanaba aphezulu e-SONET ukusayinisa ukwandisa umda wendlela yokuhamba ngokuphindaphindiweyo kwezine, ukuya kwi-40 Gbps.
Isantya seSONET senze iteknoloji kukhuphiswano kunye nezinye iindlela ezifana ne-Asynchroneous Transfer Mode kunye neGigabit Ethernet iminyaka emininzi. Nangona kunjalo, njengoko imigangatho ye-Ethernet iye yaqhubela phambili kwiminyaka emibini edluleyo, ibe yinto ethandwayo yokutshintshwa kwezibonelelo zakwa-SONET zokuguga.
