I-MyLink ™ Netpass edlula ompompi obunobuchwepheshe bezinhliziyo zenhliziyo inikezela ukuphepha kwenethiwekhi yesikhathi sangempela ngaphandle kokudela ukuthembeka kwenethiwekhi noma ukutholakala. I-MyLink ™ Network Bypass ampompi nge-10/40 / 100G ye-Bypass module inikezela ukusebenza okusheshayo okudingekayo ukuxhuma amathuluzi okuphepha nokuvikela ithrafikhi yenethiwekhi ngesikhathi sangempela ngaphandle kokulahleka kwephakethe.
Okokuqala, kunjani?
Ngokuvamile, kusetshenziswa idivaysi yokuphepha kwenethiwekhi phakathi kwamanethiwekhi amabili noma ngaphezulu, njenge-intranet nenethiwekhi yangaphandle. Uhlelo lokufaka isicelo kudivayisi yezokuphepha kwenethiwekhi luhlaziya amaphakethe enethiwekhi ukuthola ukuthi izinsongo zikhona yini, bese zidlulisela amaphakethe ngokuya ngemithetho ethile yomzila. Uma idivaysi yezokuphepha yenethiwekhi inephutha, ngokwesibonelo, ngemuva kokuhluleka kwamandla noma ukuphahlazeka, izingxenye zenethiwekhi ezixhunywe kudivayisi zizolahlekelwa ukuxhumana nomunye. Ngalesi sikhathi, uma inethiwekhi ngayinye idinga ukuxhumeka komunye nomunye, kufanele idlule phambili.
I-BYPAS, njengoba igama lisho, ngumsebenzi owedlule, okusho ukuthi amanethiwekhi amabili angahle ahlolwe ngqo ngohlelo lwedivayisi yezokuphepha yenethiwekhi ngokusebenzisa isimo esithile se-trigger (ukwehluleka kwamandla noma ukuvalwa kwamandla). Ngemuva kokuthi i-Bypass inikwe amandla, lapho idivaysi yezokuphepha yenethiwekhi yehluleka, inethiwekhi exhunywe kwidivaysi ye-Bysspass iyakwazi ukuxhumana nomunye. Kulokhu, idivaysi ye-BytPass ayicubunguli amaphakethe kunethiwekhi.
Okwesibili, ukuhlukaniswa kweBypass kusetshenziswa ngalezi zindlela ezilandelayo:
I-ByPass ihlukaniswe ngezindlela ezilandelayo: Imodi yokulawula noma imodi ye-Trigger
1. Kubangelwa ukunikezwa kwamandla. Kule modi, umsebenzi we-Bypass unikwe amandla lapho ifoni ingasebenzi. Lapho idivaysi inikwa amandla, i-bypass icishiwe ngokushesha.
2. Kulawulwa yi-GPIO. Ngemuva kokungena ngemvume ku-OS, ungasebenzisa i-GPIO ukusebenzisa amachweba athile ukulawula ukushintshwa kweBypass.
3, ngokulawulwa kwe-Watchdog. Lokhu kunwetshwa kwendlela 2 Ngale ndlela, i-Bypass ingavulwa yi-watchdog uma ipulatifomu ishayeka.
Kuzinhlelo zokusebenza ezingokoqobo, lezi zifundazwe ezintathu zivame ukuba khona ngasikhathi sinye, ikakhulukazi izindlela ezimbili 1 no-2. Indlela ejwayelekile yohlelo lokusebenza yilena: Lapho idivaysi inikwa amandla, i-bypass ivuliwe. Ngemuva kokuthi idivaysi inikwe amandla, ama-BIO angasebenza nge-bypass. Ngemuva kokuthi i-BIOS ithatha insiza, i-bypass isekhona. I-Bypass icishiwe ukuze uhlelo lokusebenza lusebenze. Ngeyo yonke inqubo yokuqalisa, cishe akukho ukunqanyulwa kwenethiwekhi.
Okokugcina, ukuhlaziya komgomo wokuqalisa kweBypass
1. Izinga le-Hardware
Ezingeni lehadiwe, i-edluliselwe ngokuyinhloko isetshenziselwa ukuqaphela ukudlula. Lokhu kudluliselwa kuxhumeke kakhulu kwizintambo zesiginali yechweba ngalinye lenethiwekhi ku-Bypass Network Port. Lesi sibalo esilandelayo sisebenzisa ikhebula elilodwa lesiginali ukufanekisa imodi yokusebenza yokudluliselwa.
Thatha i-Trigger Power njengesibonelo. Esimweni sokuhluleka kwamandla, ukushintshwa kokudluliswa kuzogxuma ku-1, okungukuthi, i-RX ethekwini le-RJ45 yeLan1 lixhumana ngqo ne-RJ45 TX ye-LAN2. Lapho idivaysi inikwa amandla, ukushintshwa kuzoxhuma ku-2. Udinga ukwenza lokho ngohlelo lokusebenza kule divayisi.
2. Ileveli yesoftware
Ekuhlukanisweni kwe-bypass, i-GPIO ne-watchdog kuxoxwa ngayo ngokulawula futhi kubangela ukudlula. Eqinisweni, zombili lezi zindlela zisebenza i-GPIO, bese i-GPIO ilawula ukudluliselwa ku-Hardware ukwenza ukugxuma okuhambisanayo. Ngokukhethekile, uma i-GPIO ehambisanayo isethwe ku-High, khona-ke ukudluliswa kuzogxumela esimweni 1. Ngakolunye uhlangothi, uma inkomishi ye-GPIO isethwe ephansi, okudluliselwe kuzogxumela esimweni 2.
Ku-Watchdog bypass, eqinisweni, ngesisekelo sokulawulwa kwe-GPIO engenhla, engeza i-Watchdog Control Bypass. Ngemuva kokuthi i-watchdog iqale ukusebenza, setha isenzo ukudlula kuma-bio. Uhlelo lunika amandla umsebenzi we-watchdog. Ngemuva kokuthi i-watchdog iqale ukusebenza, inethiwekhi ehambisanayo ye-ports bypass inikwe amandla, yenza idivaysi isesimweni se-bypass. Eqinisweni, i-Bypass nayo ilawulwa yi-GPIO. Kulokhu, ukubhala okuphansi kwe-GPIO kwenziwa yi-watchdog, futhi akukho nohlelo olwengeziwe oludingekayo ukubhala i-GPIO.
Umsebenzi we-Hardware Bypass ngumsebenzi odingekayo wemikhiqizo yokuphepha kwenethiwekhi. Lapho idivaysi inikwa amandla noma iphazanyiswa, amachweba angaphakathi nangaphandle angaxhunyaniswa komunye nomunye ukwakha ikhebula lenethiwekhi. Ngale ndlela, ithrafikhi yedatha yabasebenzisi ingadlula kudivayisi ngaphandle kokuthi ithintwe yisimo samanje sedivayisi.
