I-Mylinking™ Network Bypass TAPs ezinobuchwepheshe bokubetha kwentliziyo zibonelela ngokhuseleko lwenethiwekhi ngexesha lokwenyani ngaphandle kokuncama ukuthembeka okanye ukufumaneka kwenethiwekhi. I-Mylinking™ Network Bypass TAPs ene-10/40/100G imodyuli ye-Bypass ibonelela ngesantya esiphezulu sokusebenza esifunekayo ukudibanisa izixhobo zokhuseleko kunye nokukhusela itrafikhi yenethiwekhi ngexesha lokwenyani ngaphandle kokulahleka kwepakethi.
Okokuqala, yintoni i-Bypass?
Ngokubanzi, isixhobo sokhuseleko sothungelwano sisetyenziswa phakathi kweenethiwekhi ezimbini okanye ngaphezulu, njenge-Intranet kunye nenethiwekhi yangaphandle. Inkqubo yesicelo kwisixhobo sokhuseleko sothungelwano ihlalutya iipakethi zenethwekhi ukumisela ukuba ingaba izoyikiso zikhona na, ize ke ithumele iipakethi ngokwemigaqo ethile yomzila. Ukuba isixhobo sokhuseleko senethiwekhi sinempazamo, Umzekelo, emva kokusilela kombane okanye ukuphazamiseka, iisegmenti zenethiwekhi eziqhagamshelwe kwisixhobo ziya kuphulukana nonxibelelwano. Ngeli xesha, ukuba inethiwekhi nganye kufuneka idityaniswe enye kwenye, kufuneka ibe yi-Bypass phambili.
I-Bypas, njengoko igama libonisa, ngumsebenzi ogqithisiweyo, okuthetha ukuba uthungelwano ezimbini zinokuhanjiswa ngokwasemzimbeni ngokuthe ngqo ngenkqubo yesixhobo sokhuseleko sothungelwano ngemeko ethile yokuqalisa (ukusilela kwamandla okanye ukuvala). Emva kokuba i-Bypass ivuliwe, xa isixhobo sokhuseleko senethiwekhi singaphumeleli, inethiwekhi eqhagamshelwe kwisixhobo sokugqitha inokunxibelelana omnye nomnye. Kule meko, isixhobo sokudlula asiqhubeki iipakethi kwinethiwekhi.
Okwesibini, ulwahlulo lwe-Bypass lusetyenziswa ngezi ndlela zilandelayo:
I-Bypass yahlulwe ngezi ndlela zilandelayo: imo yokulawula okanye imodi yokuqalisa
1. Ukuqhutywa ngumbane. Kule mowudi, umsebenzi we-Bypass uyenziwa xa isixhobo singaqhutywanga. Xa isixhobo sisebenza, i-Bypass icinyiwe ngoko nangoko.
2. Ilawulwa yiGPIO. Emva kokungena kwi-OS, ungasebenzisa i-GPIO ukusebenzisa izibuko ezithile ukulawula iswitshi ye-Bypass.
I-3, ngolawulo lwe-Watchdog. Olu lulwandiso lweNdlela yesi-2. Ungasebenzisa i-Watchdog ukulawula ukusebenza kunye nokukhubaza inkqubo ye-GPIO Bypass, ukuze ulawule ubume be-Bypass. Ngale ndlela, i-Bypass ingavulwa yi-Watchdog ukuba iqonga liyaphazamiseka.
Kwizicelo ezisebenzayo, la mazwe mathathu ahlala ekhona ngexesha elinye, ngakumbi iindlela ezimbini ze-1 kunye ne-2. Indlela yesicelo ngokubanzi yile: Xa isixhobo sicinyiwe, i-Bypass ivuliwe. Emva kokuba isixhobo sinikwe amandla, i-BIOS inokusebenzisa i-Bypass. Emva kokuba i-BIOS ithatha isixhobo, i-Bypass isasebenza. I-Bypass icinyiwe ukuze usetyenziso lusebenze. Ngexesha layo yonke inkqubo yokuqalisa, phantse akukho luqhawulo lwenethiwekhi.
Okokugqibela, Uhlalutyo lomgaqo wokuphunyezwa kwe-Bypass
1. Inqanaba le-Hardware
Kwinqanaba le-hardware, i-relay isetyenziselwa ukuqaphela i-Bypass. Ezi zikhuseli ziqhagamshelwe ikakhulu kwiintambo zomqondiso zezibuko ngalinye lothungelwano kwizibuko lothungelwano lwe-Bypass. Lo mfanekiso ulandelayo usebenzisa ikhebula lomqondiso omnye ukubonisa indlela yokusebenza yerelay.
Thatha i-trigger yamandla njengomzekelo. Kwimeko yokungaphumeleli kwamandla, ukutshintshela kwi-relay kuya kuxhuma kwi-1, oko kukuthi, i-Rx kwi-port ye-RJ45 ye-LAN1 inxibelelana ngokuthe ngqo ne-RJ45 Tx ye-LAN2. Xa isixhobo sivuliwe, umtshintshi uya kuxhuma kwi-2. Kufuneka wenze oko nge-app kule sixhobo.
2. Inqanaba leSoftware
Kuluhlu lwe-Bypass, i-GPIO kunye ne-Watchdog zixutyushwa ukuze zilawule kwaye ziqalise i-Bypass. Enyanisweni, zombini ezi ndlela zisebenza i-GPIO, kwaye ke i-GPIO ilawula i-relay kwi-hardware ukwenza i-jump ehambelanayo. Ngokukodwa, ukuba i-GPIO ehambelanayo isetelwe phezulu, i-relay iya kuxhuma kwindawo ye-1. Ngokuchaseneyo, ukuba indebe ye-GPIO ibekwe phantsi, i-relay iya kuxhuma kwindawo yesi-2.
Kwi-Watchdog Bypass, eqinisweni, ngesiseko solawulo lwe-GPIO olungentla, yongeza i-Bypass yokulawula i-Watchdog. Emva kokuba i-watchdog isebenze, setha isenzo sokudlula kwi-BIOS. Inkqubo yenza umsebenzi we-Watchdog. Emva kokuba i-Watchdog iqala ukusebenza, i-port yenethiwekhi ehambelanayo ye-Bypass inikwe amandla, yenza isixhobo kwi-Bypass state. Enyanisweni, i-Bypass ilawulwa yi-GPIO. Kule meko, ukubhala okuphantsi kwe-GPIO kwenziwa yi-Watchdog, kwaye akukho nkqubo eyongezelelweyo ifunekayo ukubhala i-GPIO.
Umsebenzi we-Hardware Bypass ngumsebenzi oyimfuneko weemveliso zokhuseleko lwenethiwekhi. Xa isixhobo sicinyiwe okanye siphazamisekile, izibuko zangaphakathi nangaphandle zinokudityaniswa ngokwasemzimbeni ukuze zenze intambo yenethiwekhi. Ngale ndlela, ukugcwala kwedatha yabasebenzisi kunokudlula kwisixhobo ngaphandle kokuchatshazelwa yimeko yangoku yesixhobo.
