Kwintsimi yeenethiwekhi ezibanzi, iitekhnoloji ezimbini ezibalaseleyo ziye zezona ndawo zikhuphisana ziphambili ekuboneleleni ngeenkonzo ze-Intanethi eziphakamileyo: i-ENon kunye neGEN. Ngelixa zombini zibonisa ukusebenza okufanayo, zineempawu ezikhethekileyo ezikufanele zikufanele ukuhlola amandla abo kwaye zithathe isigqibo sokuba yeyiphi eyona ilungele iimfuno zakho.
I-ENON . Bayinxalenye yenethiwekhi ye-PON) yoSapho (i-PN) yeTekhnoloji; Nangona kunjalo, bahluke ngoyilo kunye nokusebenza.
Umahluko ophambili phakathi kwe-Eonnion kunye ne-GNONS lulawulo lwemithombo yolawulo lweendaba (i-MAC). I-ENINE isebenzisa i-Ethernet, itekhnoloji efanayo esetyenziswa kwinethiwekhi yendawo yengingqi (i-LAN) kunye neeNethiwekhi zeNdawo (i-Wan). Ngokuqesha i-Ethernet e-Ethernet, i-ENTE ibonelela ngokuhambelana neenkqubo ezisekwe kwi-EEERNet, zenza ukhetho oluqhelekileyo lokusebenza kwenethiwekhi.GpnKwelinye icala, isebenzisa itekhnoloji yokudluliselwa kwe-ATMNGRANNOUS Inzuzo yokusebenzisa i-ATM kwinethiwekhi ye-GNT kukuba ikwazi ukubonelela ngeenkonzo zokudlala kathathu (izwi, ividiyo kunye nedatha) kwiqonga le-Bhwist eQhelekileyo, ngaloo ndlela kuqinisekisa ukusetyenziswa ngokukodwa kwebhendi.
Olunye umahluko obaluleke kakhulu kukwenza isantya sokudluliselwa kwesantya esincinci kunye nesantya sokutshintsha. Ngokwesiqhelo i-ENTE inikezela ngesantya se-symmetrical, okhutshelweyo okhutshelweyo kunye nezantya zesantya ziyafana. Ngokwahlukileyo koko, i-GNNNP isebenzisa ukuseta indawo ye-asymmetric evumela ukwenziwa okuphezulu okwenziweyo kunye nezantya ezisezantsi. Eli nqaku lenza ukuba i-Gan ilungele izicelo ezifuna izicelo zokukhuphela ngokukhawuleza ngesantya, njengokusasazwa kwevidiyo kunye nokudluliselwa kwefayile enkulu. Ngokwahlukileyo, isantya se-entem somminzi senze ukuba ilungele ukusetyenziswa kwezicelo ezixhomekeke kakhulu kusulelo lwedatha ye-Symetrical, njengeenkomfa zevidiyo kunye neenkonzo zefu.
Nangona zombini i-eon kunye ne-GNON ixhasa iziseko zophuhliso ezifanayo, i-olt yazo (i-termical yomgca) kunye ne-ont (i-ont terminal) yetekhnoloji ye-terminal) itekhnoloji ye-terminal yenethiwekhi yahlukile. I-GNON inokuxhasa inani elikhulu lee-OES nge-olt nganye, esenza ukhetho lokuqala xa ukonakala yinkxalabo. Ngapha koko, kunelinye icala, inabasebenzi abavumela abaqhubi beenethiwekhi ukongeza ukuqhagamshelwa ngakumbi kwi-ofisi ye-ofisi ye-ofisi ye-ofisi ye-ofisi okanye kwindawo yokuhambisa. Eli nqaku lenza ukuba i-ENINE iluncedo ekugubungele iindawo ezinkulu zendawo.
Ukusuka kwimbono yeendleko, i-ENUon kunye neGon yahluka ngokwemirhumo yokuqala yokuseta. Ngenxa yoyilo lwayo olusekwe kwi-ATM, GEN ifuna ukuba izixhobo ezinzima nezibizi kakhulu. Ngokwahlukileyo koko, i-imeyile isebenzisa itekhnoloji ye-Ethernet, eyamkelwe ngokubanzi kwaye ingabizi kakhulu. Nangona kunjalo, kufanelekile ukuba ukuthoba ukuba njengetekhnoloji iphucule kwaye abathengisi abaninzi bafaka imakethi, umsantsa weendleko phakathi kwezi ndlela zimbini zinciphile.
Isishwankathelo, zombini i-eon kunye ne-GNON zizinto ezinokwenzeka zokubonelela nge-Intanethi ye-Intanethi. Ukuhambelana kwe-ethernet kunye ne-Symmetrical Symmetrical yenze ukuba ibonakale ishishini kunye nezicelo zokuhlala ezifuna usulelo lwedatha olulinganayo. Kwelinye icala, ukusetyenziswa kwe-GNNN kunye nezantya ze-ATMMMMMMMMMMETCric kwenza ukhetho lokuqala lwezicelo ezifuna izicelo zokukhuphela ngokukhawuleza isantya. Ukuqonda umahluko phakathi kwe-Eonnion kunye neGon kuya kunceda abaqhubi benethiwekhi kunye nabasebenzisi bokuphela benza izigqibo ezinolwazi xa bekhetha itekhnoloji efanelekile iimfuno zabo ezifanelekileyo.
