Mylinking™ Network Bypass TAPs ine moyo wetekinoroji inopa chaiyo-nguva yetiweki chengetedzo pasina kupa kuvimbika kwetiweki kana kuwanikwa. Mylinking™ Network Bypass TAPs ine 10/40/100G Bypass module inopa yakanyanya-kumhanya kuita kunodiwa kubatanidza kuchengetedza maturusi uye kudzivirira network traffic munguva chaiyo pasina kurasikirwa kwepaketi.
Kutanga, chii chinonzi Bypass?
Kazhinji, network yekuchengetedza mudziyo inoshandiswa pakati pematanho maviri kana anopfuura, senge Intranet uye yekunze network. Chirongwa chekushandisa pane network kuchengetedza mudziyo inoongorora mapaketi etiweki kuti ione kana kutyisidzira kuripo, uye yozoendesa mberi mapaketi zvinoenderana nemimwe mitemo yenzira. Kana iyo network yekuchengetedza mudziyo inokanganisa, Semuenzaniso, mushure mekutadza kwemagetsi kana kuparara, zvikamu zvetiweki zvakabatana kune mudziyo zvicharasikirwa nekusangana. Panguva ino, kana network yega yega ichida kubatana kune mumwe nemumwe, inofanira kunge iri Bypass kumberi.
Bypas, sezvinoreva zita, ibasa rakapfuura, izvo zvinoreva kuti network mbiri dzinogona kufambiswa zvakananga kuburikidza netiweki chengetedzo mudziyo system kuburikidza neyakananga trigger mamiriro (simba kutadza kana kudzima). Mushure mekunge Bypass yagoneswa, kana network yekuchengetedza mudziyo ikatadza, network yakabatana neiyo bypass mudziyo inogona kutaurirana. Muchiitiko ichi, iyo bypass mudziyo haigadziri mapaketi pane network.
Chechipiri, iyo Bypass classification inoshandiswa nenzira dzinotevera:
Bypass yakakamurwa kuva anotevera modes: control mode kana trigger mode
1. Yakakonzerwa nemagetsi emagetsi. Mune iyi modhi, iyo Bypass basa inogoneswa kana mudziyo usina simba. Kana mudziyo uchinge wabatidzwa, iyo Bypass inodzima pakarepo.
2. Inodzorwa neGPIO. Mushure mekupinda muOS, unogona kushandisa GPIO kushanda chaiyo madoko kudzora Bypass switch.
3, neWatchdog control. Uku ndiko kuwedzera kweMethod 2. Unogona kushandisa Watchdog kudzora kugonesa uye kudzima chirongwa cheGPIO Bypass, kuitira kuti udzore mamiriro eBypass. Nenzira iyi, iyo Bypass inogona kuvhurwa neWatchdog kana chikuva chaparara.
Mumashandisirwo anoshanda, aya matatu anoti anowanzo kuvepo panguva imwe chete, kunyanya nzira mbiri 1 uye 2. Iyo yakawanda yekushandisa nzira ndeye: Kana mudziyo wakadzimwa, iyo Bypass inobatidzwa. Mushure mekunge mudziyo wabatidzwa, BIOS inogona kushandisa Bypass. Mushure mekunge BIOS yatora mudziyo, iyo Bypass ichiri. Iyo Bypass inodzimwa kuti application ishande. Munguva yese yekutanga maitiro, pane kanenge pasina network kubviswa.
Chekupedzisira, Ongororo yemusimboti weBypass kuita
1. Hardware level
Padanho rehardware, relay inonyanya kushandiswa kuona Bypass. Aya mareyi anonyanya kubatanidzwa kune masaini tambo dzeimwe netiweki port paBypass network port. Nhamba inotevera inoshandisa tambo imwe yechiratidzo kuratidza maitiro ekushanda kweiyo relay.
Tora mutsara wemagetsi semuenzaniso. Muchiitiko chekukundikana kwesimba, shanduko mu relay ichasvetukira ku1, kureva kuti, Rx muRJ45 port yeLAN1 inotaurirana zvakananga neRJ45 Tx yeLAN2. Kana chigadzirwa chacho chichishandiswa, shanduko ichabatana ne 2. Unofanira kuita izvozvo kuburikidza ne-app pane iyi kifaa.
2. Software level
Muchikamu cheBypass, GPIO uye Watchdog inokurukurwa kudzora uye kukonzeresa Bypass. Muchokwadi, nzira mbiri idzi dzinoshanda iyo GPIO, uyezve GPIO inodzora relay pane Hardware kuita kusvetukira kunoenderana. Kunyanya, kana iyo GPIO inoenderana yaiswa kumusoro, ipapo relay ichasvetuka kuenda kune chinzvimbo 1. Ukuwo, kana iyo GPIO kapu yakadzikira, iyo relay inosvetukira kune chinzvimbo 2.
YeWatchdog Bypass, chokwadi, pahwaro hwepamusoro GPIO kutonga, wedzera Watchdog control Bypass. Mushure mekunge watchdog yatanga kushanda, isa chiito chekupfuura muBIOS. Iyo sisitimu inogonesa iyo Watchdog basa. Mushure mekunge Watchdog yatanga kushanda, iyo inoenderana netiweki port Bypass inogoneswa, ichiita chishandiso muBypass state. Muchokwadi, iyo Bypass inodzorwawo neGPIO. Muchiitiko ichi, kunyorwa kwepasi-pasi kuGPIO kunoitwa neWatchdog, uye hapana imwe purogiramu inodiwa kunyora GPIO.
Iyo Hardware Bypass basa ibasa rinodikanwa retiweki kuchengetedza zvigadzirwa. Kana mudziyo uchinge wadzimwa kana kuvhiringwa, madoko emukati neekunze anogona kubatanidzwa kune mumwe nemumwe kugadzira tambo yetiweki. Nenzira iyi, data traffic yevashandisi inogona kupfuura nepamudziyo pasina kukanganiswa nemamiriro azvino echishandiso.
