Ama-TAP e-Mylinking™ Network Bypass anobuchwepheshe bokushaya kwenhliziyo ahlinzeka ngokuphepha kwenethiwekhi ngesikhathi sangempela ngaphandle kokunciphisa ukuthembeka noma ukutholakala kwenethiwekhi. Ama-TAP e-Mylinking™ Network Bypass anemojuli ye-10/40/100G Bypass ahlinzeka ngokusebenza kwesivinini esiphezulu okudingekayo ukuxhuma amathuluzi okuphepha nokuvikela ithrafikhi yenethiwekhi ngesikhathi sangempela ngaphandle kokulahleka kwephakethe.
Okokuqala, iyini i-Bypass?
Ngokuvamile, idivayisi yokuphepha kwenethiwekhi isetshenziswa phakathi kwamanethiwekhi amabili noma ngaphezulu, njenge-Intranet kanye nenethiwekhi yangaphandle. Uhlelo lokusebenza kudivayisi yokuphepha kwenethiwekhi luhlaziya amaphakethe enethiwekhi ukuze lunqume ukuthi kukhona yini izinsongo, bese ludlulisela phambili amaphakethe ngokwemithetho ethile yokuqondisa. Uma idivayisi yokuphepha kwenethiwekhi inephutha, Isibonelo, ngemva kokwehluleka kwamandla noma ukuphahlazeka, izingxenye zenethiwekhi ezixhunywe kudivayisi zizolahlekelwa ukuxhumana. Ngalesi sikhathi, uma inethiwekhi ngayinye idinga ukuxhunywa komunye nomunye, kumele idlule phambili.
I-Bypas, njengoba igama lisho, iwumsebenzi odlule, okusho ukuthi amanethiwekhi amabili angahanjiswa ngqo ohlelweni lwedivayisi yokuphepha kwenethiwekhi ngesimo esithile sokubangela (ukwehluleka kwamandla noma ukuvala). Ngemva kokuthi i-Bypass ivuliwe, lapho idivayisi yokuphepha kwenethiwekhi yehluleka, inethiwekhi exhunywe kudivayisi ye-bypass ingakwazi ukuxhumana. Kulokhu, idivayisi ye-bypass ayicubunguli amaphakethe kunethiwekhi.
Okwesibili, ukuhlukaniswa kwe-Bypass kusetshenziswa ngezindlela ezilandelayo:
I-Bypass ihlukaniswe ngezindlela ezilandelayo: imodi yokulawula noma imodi yokuqalisa
1. Kuqalwa ukunikezwa kwamandla. Kule modi, umsebenzi we-Bypass uvulwa uma idivayisi ingavuliwe. Uma idivayisi ivuliwe, i-Bypass icishwa ngokushesha.
2. Kulawulwa yi-GPIO. Ngemva kokungena ngemvume ku-OS, ungasebenzisa i-GPIO ukusebenzisa amachweba athile ukulawula iswishi ye-Bypass.
3, ngokulawula i-Watchdog. Lokhu kuyisandiso seNdlela 2. Ungasebenzisa i-Watchdog ukulawula ukuvulwa nokukhutshazwa kohlelo lwe-GPIO Bypass, ukuze ulawule isimo se-Bypass. Ngale ndlela, i-Bypass ingavulwa yi-Watchdog uma ipulatifomu iphahlazeka.
Ezinhlelweni ezisebenzayo, lezi zimo ezintathu zivame ukuba khona ngesikhathi esisodwa, ikakhulukazi izindlela ezimbili 1 no-2. Indlela ejwayelekile yokufaka isicelo yile: Uma idivayisi icishiwe, i-Bypass ivuliwe. Ngemva kokuthi idivayisi ivuliwe, i-BIOS ingasebenzisa i-Bypass. Ngemva kokuthi i-BIOS ithathe idivayisi, i-Bypass isavuliwe. I-Bypass iyacinywa ukuze uhlelo lokusebenza lusebenze. Phakathi nenqubo yonke yokuqalisa, cishe akukho ukunqanyulwa kwenethiwekhi.
Okokugcina, Ukuhlaziywa kwesimiso sokusetshenziswa kwe-Bypass
1. Izinga lehadiwe
Ezingeni lehadiwe, i-relay isetshenziswa kakhulu ukwenza i-Bypass. Lawa ma-relay axhunywe kakhulu ezintanjeni zesignali ze-port ngayinye yenethiwekhi e-port yenethiwekhi ye-Bypass. Isithombe esilandelayo sisebenzisa ikhebula lesignali elilodwa ukubonisa imodi yokusebenza ye-relay.
Thatha isiqalisi samandla njengesibonelo. Uma kwenzeka ugesi uphela, inkinobho eku-relay izokweqa iye ku-1, okungukuthi, i-Rx echwebeni le-RJ45 le-LAN1 ixhumana ngqo ne-RJ45 Tx ye-LAN2. Uma idivayisi ivuliwe, inkinobho izoxhuma ku-2. Udinga ukwenza lokho ngohlelo lokusebenza olukule divayisi.
2. Izinga lesofthiwe
Ekuhlukanisweni kwe-Bypass, i-GPIO kanye ne-Watchdog kuxoxwa ngazo ukulawula nokuqalisa i-Bypass. Eqinisweni, zombili lezi zindlela zisebenza i-GPIO, bese i-GPIO ilawula i-relay kuhadiwe ukuze yenze ukugxuma okuhambisanayo. Ngokukhethekile, uma i-GPIO ehambisanayo isethwe phezulu, khona-ke i-relay izogxumela endaweni 1. Ngokuphambene nalokho, uma indebe ye-GPIO isethwe phansi, i-relay izogxumela endaweni 2.
Eqinisweni, kwi-Watchdog Bypass, ngokusekelwe kulawulo lwe-GPIO olungenhla, engeza i-Watchdog control Bypass. Ngemva kokuthi i-watchdog iqalile ukusebenza, setha isenzo sokudlula ku-BIOS. Uhlelo luvumela umsebenzi we-Watchdog. Ngemva kokuthi i-Watchdog iqalile ukusebenza, i-port yenethiwekhi ehambisanayo i-Bypass iyasebenza, okwenza idivayisi ibe sesimweni se-Bypass. Eqinisweni, i-Bypass nayo ilawulwa yi-GPIO. Kulokhu, ukubhala okuphansi ku-GPIO kwenziwa yi-Watchdog, futhi akukho zinhlelo ezengeziwe ezidingekayo ukuze kubhalwe i-GPIO.
Umsebenzi we-hardware Bypass uwumsebenzi odingekayo wemikhiqizo yokuphepha kwenethiwekhi. Uma idivayisi icishiwe noma iphazamisekile, ama-port angaphakathi nangaphandle angaxhunywa ngokomzimba ukuze kwakheke ikhebula lenethiwekhi. Ngale ndlela, ithrafikhi yedatha yabasebenzisi ingadlula kudivayisi ngaphandle kokuthintwa yisimo samanje sedivayisi.
