Kukurumidza uye kuchengeteka ndezvipi zvezvikomborero zveSONET
SONET inyanzvi yehutachiona yakagadzirirwa kutakura zvinhu zvakawanda zvemigwagwa pamusoro pemakiromita akareba pane fiber optic cabling . SONET pakutanga yakagadzirwa neAmerican National Standards Institute yeUnited States network network pakati pe1980. Izvi zvakagadziriswa digital digital communication protocol inotumira zvinhu zvakasiyana-siyana zvemashoko panguva imwe chete.
Sonet Characteristics
SONET ane zviitiko zvakasiyana siyana zvinoita kuti zvifadze, kusanganisira:
- SONET inoda zviduku zvishoma kudarika mamwe maitiro uye inopa kuwedzera kwenzvimbo kuvimbika.
- SONET inotsanangura zvakajeka kushandiswa kwemitemo pakati pevatengesi vakasiyana-siyana.
- SONET inogona kutakura chero chero ipi zvayo yepamusoro-protocol inosanganisira IP.
- SONET inosanganisira yakagadzirirwa mukati-mutsotsi pakusununguka kwekutarisira nekugadzirisa.
- SONET inotsigira marudzi ose emigwagwa kusanganisira izwi, data, uye video.
- SONET inopa kuchengeteka kwakakwirira kudarika mamwe maitiro.
Izvo zvakagutsikana kuti hazvina kunaka zveSONET ndezvayo mari yakakwirira.
SONET inowanzoshandiswa mumagetsi ekutakura nhare. Inowanikawo pamisasa uye mumakwikwi.
Performance
SONET inoita zvakanyanya kwazvo. Pachigadziko chekuisa pasi, chinonzi STS-1, SONET inotsigira 51.84 Mbps. Nhamba inotevera yeSONET kuisa chiratidzo, STS-3, inotsigira katatu bhetwidth, kana 155.52 Mbps. Nhamba dzakakwirira dzeSONET kuratidza kuwedzera bandwidth muzvidimbu zvinopfurikidza zvevana, kusvika kusvika 40 Gbps.
Nhanho yeSONET yakaita kuti teknolojia ipikisane nemamwe nzira dzakadaro seAsynchronous Transfer Mode uye Gigabit Ethernet kwemakore mazhinji. Zvisinei, sezvo mitemo yeEthernet yave ichipfuurira mberi kwemakumi maviri emakore adarika, yakashandurwa pakuzivikanwa kwekukwegura kweSONET infrastructure.
