Ama-routers amaningi asekhaya asebenzisa ubuchwepheshe obunamaphesenti
Kuxhumano lwekhompiyutha olulinganiselwe, wonke amadivaysi adlulisa futhi athola idatha ngamanani alinganayo. Amanethiwekhi angama-asymmetric, ngakolunye uhlangothi, asekela umkhawulokudonsa ngokungahambisani nakakhulu kunoma iyiphi enye.
Isizathu Sokukhetha Ukungahambisani Ne-Tech Symmetric
Ngokusakazwa kwama-movie we-streaming nemiboniso yethelevishini ku-intanethi, i-router yasekhaya evame ukucelwa ukuthi ilande inani elikhulu ledatha ngendlela yokusakaza ividiyo kunomndeni ozokwazi ukulayisha. Lapha lapho ubuchwepheshe be-asymmetric bufika kahle. Ama-routers amaningi asekhaya asethelwe ukubhekana nalokhu kungavumelani phakathi kwenani lokulandwa kwedatha nokulayishwa kwedatha. Ezimweni eziningi, ikhamera noma inkampani ye-satellite ngokwayo inikeza ngesivinini esikhulu sokulanda kunesivinini sokulayishwa ngesizathu esifanayo.
Isibonelo, ubuchwepheshe be- Digital Subscriber Line (DSL) bukhona emafomu womabili kanye namasymmetric. I-DSL ye-Asymmetric (i-ADSL) inikeza ukuhamba komkhawulo okuningi okulandwayo ngokulandelana komkhawulokudonsa okutholakala ukulayishwa. Ngakolunye uhlangothi, i-DSL ye-symmetric isekela umkhawulokudonsa ofanayo kuzo zombili izinkomba. Izinsizakalo ze-inthanethi zokusetshenziswa kwekhaya zivame ukusekela i-ADSL ngoba abasebenzisi abasebenzisa i-intanethi bavame ukulanda idatha engaphezulu kunalokho abayilayishayo. Amanethiwekhi eBhizinisi asebenzisa kakhulu i-SDSL.
I-Symmetric vs. i-Asymmetric ku-Networking
I-Symmetry ne-asymmetry nayo isebenza kumklamo wenethiwekhi ngezindlela ezijwayelekile. Umklamo wenethiwekhi olinganiselwe unikeza wonke amadivayisi ukufinyelela okulinganayo ezinsizeni, kanti amanethiwekhi asymmetric ahlukanisa ukufinyelela kwemithombo ngokungalingani. Isibonelo, amanethiwekhi "ahlanzekile" we- P2P angathembeki kumaseva angaphakathi ayingqayizivele, kanti amanye amanethiwekhi we-P2P ajwayelekile.
Okokugcina, ekuvikeleni kwenethiwekhi , kokubili ama-symmetric nezinhlobo ezingafani zokubethelwa zikhona. Amasistimu wokubethela we-Symmetric ahlanganyela okhiye bokubhala ngokufanayo phakathi kokubili kokuphela kokuxhumana kwenethiwekhi. Amasistimu wokubethela okungafaniyo asebenzisa izinkinobho zokubethela ezahlukene-ezifana zomphakathi nezangasese-ekupheleni kokuphela kokuxhumana.
