Ulayini lwesakhelo ngqamaniso lwekhonkco lwedatha, iteknoloji yenethiwekhi yokuguqulela ipakethe yokuguqulela idijithali eyenzelwe ukudibanisa iInternet Area Networks (LANs) kunye nokudlulisa idatha kwiWide Area Networks (WANs) . I-Frame Relay ikwabelana ngenye inyeknoloji efana ne- X.25 kwaye iphumelele ukuthandwa kwi-United States njengesixhobo esisezantsi seenkonzo ze-Digital Digital Network (ISDN) iinkonzo ezithengiswa kubathengi bezorhwebo.
Ilayini yeReferensi isebenza njani
I-Relay Framework isekela ukuxilongwa kwetrato kwiindawo ezinxibelelwano ezininzi kwikhonkco ekwabelwana ngayo ngokusebenzisa i-hardware eneenjongo ezizodwa ezibandakanya i-routers, i-bridges kunye nokutshintshela okufakela idatha kwimilayezo yeRe Frame Relay. Ikhonkco nganye isebenzisa isishumi (10) seNgcaciso soNxibelelwano lweNxulumano lweDatha (DLCI) kwi-channel ekhethekileyo yokuthetha. Iintlobo ezimbini zokuxhamla zikhona:
- Ii-Circuits eziqhelekileyo ezingapheliyo (i-PVC) - ukudibanisa okuqhubekayo okujoliswe ukuba kugcinwe ixesha elide nangona akukho datha ihanjiswa
- Ukutshintshela ii-Circuits Virtual (SVC) - ukudibanisa kwexeshana ezihlala kuphela kwithuba leseshoni enye
I-Relay Reef iphumelele ukusebenza kangcono kunokuba i-X.25 ngexabiso eliphantsi ngokukodwa ayinakwenza nayiphi na impazamo yokulungiswa (oko kunokuba ilayishwe kwezinye iinqununu zenethiwekhi), ukunciphisa kakhulu i- latency yenethiwekhi . Ikwaxhasa ubukhulu beepakethi yobude bezinto eziguquguqukayo zokusetyenziswa ngokufanelekileyo kwee- bandwidth zenethiwekhi .
I-Relay Framework isebenza ngaphezu kwe- fiber optic okanye i-SDN imigca kwaye inokuxhasa iinkqubo ezahlukeneyo zeenethwekhi zenqanaba eliphezulu kuquka iProsoft Protocol (IP) .
UkuSebenza koLwakhelo lweSakhelo
I-Relay Relay isekela ixabiso leedata ze- T1 kunye ne-T3 imigca- 1.544 Mbps kunye ne-45 Mbps, ngokulandelanayo, ngokuxhunywa komntu ngamnye ukuya kwi-56 Kbps. Ikwaxhasana nefayibha yokufikelela kwi-2.4 Gbps.
Ikhonkco nganye inokuqwalaselwa nge- Committed Information Rate (CIR) ukuba umgaqo-nkqubo ugcina ungagqibekanga. I-CIR ibhekiselele kwisilinganiso esincinci seenkcukacha ukuba uxhumo lufanele ulindele ukufumana phantsi kweemeko zesigaba (kunye kwaye lunokugqithiswa xa unxibelelwano olubonakalayo lunezakhono ezaneleyo zokwenza inkxaso). I-Frame Relay ayiyikukhawulelana nokusebenza okugqithisileyo kwi-CIR kodwa iphinde ivumele i-traffic burst, apho uxhumano lunokwenziwa okwesikhashana (ngokuqhelekileyo ukuya kumasekhondi a-2) lugqithise i-CIR yalo.
Imiba enesigxina seRelay
I-Frame Relay ngokuqhelekileyo inikezela ngendlela echanekileyo yenkampani yee-telecommunications ukuba idlulise idatha kumgama omde. Le teknoloji incitshiswe ekuthandeni njengoko iinkampani zihamba ngokufudula zifudula izithuthi zazo kwezinye izicwangciso ze-Intanethi (IP) .
Kwiminyaka edlulileyo, abaninzi babecinga indlela yokuTshintshiselwa kweAnchronous (ATM) kunye neReflay Relay njengabaphiswano ngqo. I-teknoloji ye-ATM ihluke kakhulu kwi-Frame Relay, nangona kunjalo-usebenzisa ubude obude kunokuba iipakethi zendawo eguquguqukayo kwaye idinga i-hardware ebiza kakhulu ukuyisebenzisa.
I-Frame Relay ekugqibeleni ijongene nokhuphiswano olunamandla ngakumbi kwi-MPLS-I-Multi-Protocol I-Label Switch. Amacandelo e-MPLS asetyenziswe ngokubanzi kwii-routers kwi-Intanethi ukwenza iisisombululo ezibonakalayo ezizimeleyo ze-Intellectual Private Network (VPN) ezidlulileyo ngaphambili ezazifuna iRe Frame Relay okanye izisombululo ezifanayo.
