Uninzi lwee-routers zasekhaya basebenzisa iteknoloji ye-asymmetric
Ngomnatha womnatha wekhomputha, zonke iifowuni zithumela kwaye zifumana idatha ngokulinganayo. Amanethiwekhi angama-asymmetric, ngakolunye uhlangothi, axhasa ngokungafaniyo umda wobubanzi bomda ngaphaya kolunye.
Isizathu sokukhetha ukulinganisa kwi-Tech Symmetric
Ngenxa yokwanda kweefilimu zokusasaza kunye nemiboniso yethelevishini, i-router yasekhaya iyacelwa ukuba ilande inani elithe xaxa leenkcukacha ngendlela yokuhambisa ividiyo ngaphandle kwentsapho iyakwazi ukuyilayisha. Le yilapho iteknoloji ye-asymmetric ifumaneka ngokufanelekileyo. Uninzi lwee routers zasekhaya lusekwe ukujongana nokungafani phakathi kwemali yedatha ekhutshiwe kunye nedatha elayishiwe. Kwiimeko ezininzi, i-cable okanye inkampani ye-satellite ngokwayo inikeza umlinganiselo omkhulu wokukhuphela kunokuba ulayishe ngesivinini esinye isizathu.
Ngokomzekelo, ubugcisa be- Digital Subscriber Line (DSL) bukhona kwiifom zombini ezilinganayo kunye neendlela eziqhelekileyo. I-DSL ye-Asymmetric (ADSL) inikeza amaninzi omda wokulandelwa ngokukhupha i-bandwidth ekhoyo yokulayishwa. Ngakolunye uhlangothi, i-DSL ehambelanayo isekela umda wokulinganisa olinganayo kwimiba mibini. Iinkonzo ze-intanethi ngokusetyenziswa kwekhaya zixhase i-ADSL kuba abasebenzisi be-intanethi baqhele ukukhuphela idatha engaphezulu kunokuba balayishe. Amanethiwekhi amaninzi asetyenziswa ngokubanzi nge-SDSL.
I-Symmetric vs. Asymmetric kwi-Networking
I-Symmetry kunye ne-asymmetry nayo isebenza kwindlela yokucwangciswa kwenethiwekhi ngeendlela eziqhelekileyo. Uluhlu lwenethiwekhi oluhambelanayo lunikeza zonke izixhobo ukufikelela ngokulinganayo kwizixhobo, kanti amanethiwekhi amaninzi ahlukanisa ukufikelela kwizixhobo ezingafaniyo. Ngokomzekelo, "amanqatha" angama- P2P anamaxhomekeke kumaseva angundoqo ahambelana, ngelixa amanye amanxibelelwano e-P2P anqamle.
Ekugqibeleni, ekukhuselekeni kwenethiwekhi , zombini iifom ye-symmetric kunye ne-asymmetric yokubethela. Iinkqubo zokubethela i-Symmetric zikwabelana ngeefayile zokubhala ngokufanayo phakathi kokuphela kokuphela koxhulumaniso lwenethiwekhi. Iinkqubo zokubethelwa kwe-Asymmetric zisebenzisa izitshixo ezahlukeneyo zokubhala-ezifana noluntu kunye nolwangasese-kumxholo wokugqibela wokunxibelelana.
