Iindlela zihlelwe ngokweendidi ezintathu: indlela engatshintshiyo, indlela eguqukayo, kunye nendlela ethe ngqo. Kwindlela ye-manual input static routing, ukwenzela ukusombulula ingxaki yomzila we-ip yehlabathi lonke, ibuthathaka kakhulu ngokwenene. Ke, iingcali zicinga ukuvumela i-router ukusuka ekhaya, xelela abakufutshane ...

I-VPN iteknoloji yokufikelela kude, oku kuthetha nje ukusebenzisa ikhonkco yenethiwekhi yoluntu (ngokuqhelekileyo i-Intanethi) ukuseta inethiwekhi yangasese. Ngokomzekelo, ngolunye usuku umphathi uthumela uhambo lwezoshishino kwindawo apho ufuna ukufikelela kwinethiwekhi yangaphakathi yeyunithi, olu kufikelela kukufikelela kude. Ho...

I-Multiprotocol Label Switching (MPLS) yiteknoloji entsha ye-IP ye-backbone network. I-MPLS yazisa ingqikelelo yokutshintsha ileyibhile ejolise kunxibelelwano kwiinethiwekhi ze-IP ezingaxhunywanga, kwaye idibanisa itekhnoloji ye-Layer-3 yomzila kunye ne-Layer-2 yokutshintsha itekhnoloji, inika umdlalo opheleleyo wokuguquguquka kwendlela ye-IP...

Inethiwekhi yokufikelela kwi-Optical (oko kukuthi, uthungelwano lofikelelo olunokukhanya njengendlela yothumelo, endaweni yocingo lobhedu, lusetyenziselwa ukufikelela kusapho ngalunye. Inethiwekhi yokufikelela kwi-Optical) .Uthungelwano lokufikelela kwi-Optical ngokubanzi lunamacandelo amathathu: i-terminal optical line OLT, inethiwekhi yokukhanya. iyunithi ONU, ukuhanjiswa kwamehlo...

Yintoni i-ONU? Namhlanje, i-ONU eneneni ixhaphake kakhulu kubomi bethu. Uqhagamshelo lwenethiwekhi olunikezelwa ngumsebenzisi olufakwe kwikhaya lomntu wonke lubizwa ngokuba yi-Optical Modem, ekwaziwa njengesixhobo se-ONU. Inethiwekhi yomsebenzisi iqhagamshelwe kwisixhobo sokukhanya, kwaye emva koko iqhagamshelwe kwizibuko le-PON ye...

Xa sikhetha imodyuli ye-optical, ngaphezu kokupakishwa okusisiseko, umgama wokudlulisa, kunye nesantya sokudluliselwa, kufuneka sinikele ingqalelo kule miba ilandelayo: 1. Iintlobo zeFiber zohlobo lweFiber zingahlulwa zibe yimodi enye kunye ne-multi-mode. Umbindi wamaza wemowudi yendlela enye...
