(1) I-10G ye-PON yeTekhnoloji yophuhliso Umzila we-EPON olawulwa yi-IEEE, kunye ne-GPON elawulwa yi-ITU zombini ziguqukela kwi-10 GPON isigaba okwangoku kwaye ukucwangciswa okulandelayo yi-100G PON. Kukho iiyantlukwano ezithile kwiindlela ezithile zokuzivelela, kunye ne-evo ehambelanayo...

I-network ebizwa ngokuba yi-PON ineenxalenye ezintathu: i-OLT, i-ODN kunye ne-ONU.Isixhobo se-OLT sifumaneka kwisiseko se-topology yenethiwekhi. Ifikelela kwiinkonzo ezininzi zothungelwano ukuya phezulu kunye neenkonzo zabasebenzisi abaninzi ukuhla nge-ODN. Yindawo ebalulekileyo yenkonzo agg...

Umzila yinkqubo apho i-router ifumana ipakethi kwi-interface enye, iqondise ipakethi ngokwedilesi yayo kwaye iyidlulisele kwenye i-interface. Sisixhobo sokudlulisa ipakethi somaleko wothungelwano olusebenza kumaleko wesithathu we-OSI ireferensi...

I-SONET: i-synchronous optical network, umgangatho wokuhanjiswa kwedijithali, yaziswa e-United States ngo-1988. Inqanaba le-1 yesignali yombane ichazwa njenge-STS-1, kunye nenqanaba le-1 lesignali ye-optical ichazwa njenge-OC-1, enezinga le-51.84Mb. /s. Ngesi siseko, phucula ngokusebenzisa...

Iikhrayitheriya ze-IPv4 zachazwa ekupheleni koo-1970. Ekuqaleni kweminyaka yoo-1990, ukusetyenziswa kweWWW kwakhokelela ekuphuhlisweni okuqhumayo kwe-Intanethi. Ngeentlobo zezicelo ze-Intanethi eziya zisiba nzima kunye nokwahluka kwe-terminal, ubonelelo lwe-indep yehlabathi...

Ngamanye amaxesha, kunokufuneka siphumeze ikhowudi enye amaxesha amaninzi. Ngokubanzi, iinkcazo zenkqubo ziqhutywa ngokulandelelanayo: ingxelo yokuqala kumsebenzi yenzeka kuqala, ilandelwe yingxelo yesibini, njalo njalo. Iilwimi zokuprograma zibonelela ngeendlela ezininzi zolawulo...
