Ii-Mylinking™ Network Bypass TAPs ezineteknoloji ye-heartbeat zibonelela ngokhuseleko lwenethiwekhi ngexesha langempela ngaphandle kokunciphisa ukuthembeka okanye ukufumaneka kwenethiwekhi. Ii-Mylinking™ Network Bypass TAPs ezine-10/40/100G Bypass module zibonelela ngokusebenza okukhawulezayo okufunekayo ukuqhagamshela izixhobo zokhuseleko kunye nokukhusela ithrafikhi yenethiwekhi ngexesha langempela ngaphandle kokulahleka kwepakethe.
Okokuqala, yintoni iBypass?
Ngokubanzi, isixhobo sokhuseleko lwenethiwekhi sisetyenziswa phakathi kweenethiwekhi ezimbini okanye ngaphezulu, njenge-Intranet kunye nenethiwekhi yangaphandle. Inkqubo yesicelo kwisixhobo sokhuseleko lwenethiwekhi ihlalutya iipakethi zenethiwekhi ukuze ibone ukuba kukho izisongelo na, ize ithumele iipakethi ngokwemigaqo ethile yokuhambisa. Ukuba isixhobo sokhuseleko lwenethiwekhi sinesiphako, Umzekelo, emva kokucima kombane okanye ukuphahlazeka, amacandelo enethiwekhi aqhagamshelwe kwisixhobo aya kulahlekelwa kukunxibelelana. Ngeli xesha, ukuba inethiwekhi nganye kufuneka iqhagamshelwe kwenye, kufuneka idlule phambili.
I-Bypas, njengoko igama lisitsho, ngumsebenzi ogqithiweyo, nto leyo ethetha ukuba iinethiwekhi ezimbini zinokudluliselwa ngqo kwinkqubo yesixhobo sokhuseleko senethiwekhi ngemeko ethile yokubangela (ukusilela kombane okanye ukucima). Emva kokuba i-Bypass ivuliwe, xa isixhobo sokhuseleko senethiwekhi singaphumeleli, inethiwekhi eqhagamshelwe kwisixhobo esigqithisileyo inokunxibelelana. Kule meko, isixhobo esigqithisileyo asicubunguli iipakethi kwinethiwekhi.
Okwesibini, udidi lwe-Bypass lusetyenziswa ngeendlela ezilandelayo:
I-Bypass yahlulwe ngokweendlela ezilandelayo: imo yokulawula okanye imo ye-trigger
1. Ivuselelwa ngumbane. Kule meko, umsebenzi we-Bypass uyasebenza xa isixhobo singavulwanga. Xa isixhobo sivuliwe, i-Bypass icinywa ngoko nangoko.
2. Ilawulwa yi-GPIO. Emva kokungena kwi-OS, ungasebenzisa i-GPIO ukusebenzisa amazibuko athile ukulawula iswitshi ye-Bypass.
3, yi-Watchdog control. Olu lolwandiso lweNdlela yesi-2. Ungasebenzisa i-Watchdog ukulawula ukuvulwa kunye nokukhutshazwa kwenkqubo ye-GPIO Bypass, ukuze ulawule imeko ye-Bypass. Ngale ndlela, i-Bypass inokuvulwa yi-Watchdog ukuba iqonga liyawa.
Kwiinkqubo ezisebenzayo, ezi meko zintathu zihlala zikhona ngaxeshanye, ingakumbi iindlela ezimbini 1 kunye no-2. Indlela eqhelekileyo yesicelo yile: Xa isixhobo sivuliwe, i-Bypass ivuliwe. Emva kokuba isixhobo sivuliwe, i-BIOS inokusebenzisa i-Bypass. Emva kokuba i-BIOS ithathe ulawulo lwesixhobo, i-Bypass isavuliwe. I-Bypass icinyiwe ukuze usetyenziso lusebenze. Ngexesha lonke lenkqubo yokuqalisa, phantse akukho kuqhawuka kwenethiwekhi.
Okokugqibela, Uhlalutyo lomgaqo wokusetyenziswa kwe-Bypass
1. Inqanaba lehardware
Kwinqanaba lezixhobo zekhompyutha, i-relay isetyenziswa kakhulu ukwenza i-Bypass. Ezi relay ziqhagamshelwe kakhulu kwiintambo zesignali zezibuko ngalinye lenethiwekhi kwizibuko lenethiwekhi ye-Bypass. Lo mfanekiso ulandelayo usebenzisa intambo yesignali enye ukubonisa indlela yokusebenza kwe-relay.
Umzekelo, thabatha isixhobo sokuqalisa umbane. Kwimeko yokusilela kombane, iswitshi kwi-relay iya kutsibela kwi-1, oko kukuthi, i-Rx kwi-port ye-RJ45 ye-LAN1 inxibelelana ngokuthe ngqo ne-RJ45 Tx ye-LAN2. Xa isixhobo sivuliwe, iswitshi iya kuqhagamshela kwi-2. Kufuneka wenze oko nge-app kwesi sixhobo.
2. Inqanaba leSoftware
Kwindlela yokwahlulahlula i-Bypass, i-GPIO kunye ne-Watchdog zixoxwa ngayo ukulawula nokuqalisa i-Bypass. Enyanisweni, zombini ezi ndlela zisebenza i-GPIO, kwaye i-GPIO ilawula i-relay kwi-hardware ukuze yenze ukutsiba okufanelekileyo. Ngokukodwa, ukuba i-GPIO ehambelanayo imiselwe phezulu, i-relay iya kutsiba kwindawo yoku-1. Ngokwahlukileyo koko, ukuba indebe ye-GPIO imiselwe phantsi, i-relay iya kutsiba kwindawo yesi-2.
Kwi-Watchdog Bypass, eneneni, ngokusekelwe kulawulo lwe-GPIO olungentla, yongeza i-Watchdog control Bypass. Emva kokuba i-watchdog iqalile ukusebenza, setha isenzo sokudlula kwi-BIOS. Inkqubo ivumela umsebenzi we-Watchdog. Emva kokuba i-Watchdog iqalile ukusebenza, i-port yenethiwekhi ehambelanayo i-Bypass iyavulwa, okwenza isixhobo sibe kwimeko ye-Bypass. Enyanisweni, i-Bypass ikwalawulwa yi-GPIO. Kule meko, ukubhala okuphantsi kwi-GPIO kwenziwa yi-Watchdog, kwaye akukho nkqubo yongezelelweyo ifunekayo ukubhala i-GPIO.
Umsebenzi we-hardware Bypass ngumsebenzi oyimfuneko kwiimveliso zokhuseleko lwenethiwekhi. Xa isixhobo sivuliwe okanye siphazamisekile, amazibuko angaphakathi nangaphandle anokuqhagamshelwa ngokwasemzimbeni ukuze enze intambo yenethiwekhi. Ngale ndlela, ithrafikhi yedatha yabasebenzisi inokudlula kwisixhobo ngaphandle kokuchaphazeleka yimeko yangoku yesixhobo.
