Ezokuxhumana, igama le- uplink libhekisela ekuxhumaneni okungenantambo okwenziwe kusuka emhlabathini kuya kwisitatimende se-satellites yokuxhumana emhlabeni. Igama elifanayo ngezinye izikhathi lisetshenziselwa ukuxhumana ngekhompiyutha futhi libhekisela kwinethiwekhi ( yocingo noma engenantambo) kusuka kunethiwekhi yendawo (LAN) kuya kunethiwekhi enkulu yendawo (WAN) .
I-Uplink ne-Downlink
I- downlink ixhumano olwenziwe ngendlela ehlukile ye-uplink, kusuka esiteshini kuya emhlabathini noma kusuka kwinethiwekhi yangaphandle ibe inethiwekhi yendawo. Ukulandwa kwe-Inthanethi, isibonelo, hamba phezu kwe-downlink kudivayisi yokulanda ngenkathi ukulayishwa kwe-Inthanethi kuhamba ngokuxhumana kwe-uplink.
Ama-Uplink asetshenziselwa ukuxhumana nge-satellites ukuze asakaze umsakazo we-satellite nethelevishini. Abasakazo bathumela izimpahla zabo zesignali kusuka eziteshini zasemhlabeni kuya kwi-satellite ejikelezayo, inqubo eyaziwa ngokuthi uplink satellite .
Izihlinzeki zezinsizakalo nezinye izinsizakalo ze-broadband zibuye zibheke emgwaqweni wokuxhumana ophezulu wamanethiwekhi abo njengokudluliswa kwe-uplink . Lezi uplink zingase zithwale imiyalezo, ukulayishwa kwefayela le-intanethi kanye nedatha ethile ethunyelwe kwinethiwekhi yomhlinzeki.
Ama-Uplink Amaports ku-Computer Networks
Ezinye i-hardware yenethiwekhi yekhompuyutha inezindawo ze-uplink ezenzelwe ukufaka izintambo zenethiwekhi . Lawa machweba avumela inethiwekhi ukuthi ixhumane namanye amanethiwekhi angaphandle. Amapayipi ase-Uplink e-routers ekhaya, isibonelo, vumela ukuxhumeka kumamodemu we-broadband ne-intanethi.
Ama- hubs e- Ethernet , ama- switches , kanye nama- router ngokuvamile aqoka elinye lamaports abo e- Ethernet njengoxhumano lwe-uplink olubekwe uphawu ngokukhethekile kwiyunithi ngamagama kanye / noma umbala. Ama- routers asekhaya asekhaya aselebulale leli port "WAN" o r "Inthanethi" kunokuthi "uplink," kodwa umqondo nomsebenzi kuyafana.
Ukuxhumeka kwe-Uplink kungasetshenziswa
- Ukuxhuma i-modem ye-broadband kumzila wekhaya wokufinyelela kwe-intanethi .
- Ukuxhuma idivayisi eyodwa ye-uplink (router, switch, hub) kwenye. Xhuma i-port uplink ye-switch eyodwa, isibonelo, endaweni ejwayelekile yesinye ishintshi ukuze wandise usayizi wenethiwekhi.
Ngakolunye uhlangothi, ukuxhumeka kwe-uplink akufanele kusetshenziselwe
- Ixhuma amabhuloho amabili e-uplink komunye nomunye
- Ukuxhuma ikhompyutha kwi-port uplink
Qaphela ukuthi, kumanethiwekhi wamanethiwekhi wamanje, ukuxhumeka kuyi- bi-directional. Ngisho nokuxhumeka kwichwethi le-uplink, ikhebula elifanayo noma isixhumanisi esingenantambo singadlulisa idatha kokubili nakumadivayisi ekupheleni kunokuba "kuphela" noma "phansi" kuphela. Imigomo uplink ne-downlink lapha isebenza ekupheleni kokuxhumana kuqala ukudluliswa kwedatha.
Izingosi zokuxhumana zingase zikhomba ukuthi ikhebula le- Ethernet crossover lingasetshenziselwa ukuxhuma ikhompuyutha ku-port uplink noma ukuxhuma amabhuloho amabili e-uplink komunye nomunye. Ngenkathi iqondiswe kahle, ukusebenziseka kwalezi zinhlobo zokuxhumeka kunqunyelwe.
Ama-Double-Purpose kanye nama-Uplink Amaports
Umbhalo wendabuko we-hardware we-port uplink isekela kuphela amadivayisi we-uplink enethiwekhi. Noma kunjalo, ama-router amaningi ase-home broadband router anikeza ichweba elizinhloso ezimbili, esikhundleni esisodwa, esingasebenza njenge-uplink noma i-port ejwayelekile kuye ngokuthi uhlobo lwedivayisi oluxhunywe kuyo.
Ngaphambi kokungathandwa kwamapayipi amabili, amanye amashrikhi enethiwekhi asebekhulile ahlela ichweba elijwayelekile eduze kwe-uplink futhi axhuma lababili ndawonye njengombhangqwana. Ngokuqondile, ilogi yehadiwe yale mikhiqizo isekela ukuxhumeka ku-port uplink, noma i-port ehlanganyelwe ejwayelekile, kodwa hhayi kokubili. Ukuxhuma amadivaysi kokubili amarekhodi wesdivaysi ephathekayo ephathekayo iyeka leyunithi ekusebenzeni kahle.
