MaTAP eMylinking™ Network Bypass ane tekinoroji yekurova kwemoyo anopa kuchengetedzeka kwenetwork panguva chaiyo pasina kukanganisa kuvimbika kwenetwork kana kuwanikwa kwayo. MaTAP eMylinking™ Network Bypass ane 10/40/100G Bypass module anopa mashandiro ekumhanya anodiwa kubatanidza maturusi ekuchengetedza uye kudzivirira traffic yenetwork munguva chaiyo pasina kurasikirwa nemapaketi.
Kutanga, chii chinonzi Bypass?
Kazhinji, mudziyo wekuchengetedza network unoshandiswa pakati pema network maviri kana anopfuura, akadai seIntranet ne network yekunze. Chirongwa chekushandisa pa network security device chinoongorora mapaketi e network kuti chione kana paine njodzi, uye chobva chatumira mapaketi zvichienderana nemitemo ye routing. Kana network security device isina kunaka, Semuenzaniso, mushure mekukundikana kwemagetsi kana kudonha, network segments dzakabatana ne device dzicharasikirwa nekubatana. Panguva ino, kana network yega yega ichida kubatana, inofanira kupfuudzwa mberi.
Bypas, sezvinoreva zita racho, ibasa rakapfuurwa, zvinoreva kuti ma network maviri anogona kufambiswa zvakananga kuburikidza nesystem ye network security device kuburikidza nemamiriro chaiwo e trigger (kukundikana kwemagetsi kana kudzima). Mushure mekunge Bypass yavhurwa, kana network security device yakundikana, network yakabatana ne bypass device inogona kutaurirana. Muchiitiko ichi, bypass device haigadzirise mapaketi pa network.
Chechipiri, kupatsanurwa kweBypass kunoshandiswa nenzira dzinotevera:
Bypass yakakamurwa kuita nzira dzinotevera: control mode kana trigger mode
1. Inokonzerwa nemagetsi. Mumuitiro uyu, basa reBypass rinobatidzwa kana mudziyo usina kubatidzwa. Kana mudziyo wabatidzwa, Bypass inodzimwa ipapo ipapo.
2. Inodzorwa neGPIO. Mushure mekupinda muOS, unogona kushandisa GPIO kushandisa maports chaiwo kudzora switch yeBypass.
3, neWatchdog control. Iyi ikuwedzera kweMethod 2. Unogona kushandisa Watchdog kudzora kubvumira uye kudzima chirongwa cheGPIO Bypass, kuitira kudzora mamiriro eBypass. Nenzira iyi, Bypass inogona kuvhurwa neWatchdog kana puratifomu ikadonha.
Mumashandisirwo anoitwa, mamiriro matatu aya anowanzovapo panguva imwe chete, kunyanya nzira mbiri 1 ne2. Nzira yekushandisa yakawanda ndeiyi: Kana mudziyo wadzimwa, Bypass inenge yabatidzwa. Kana mudziyo wabatidzwa, BIOS inogona kushandisa Bypass. Mushure mekunge BIOS yatora mudziyo, Bypass inenge ichiri kushanda. Bypass inodzimwa kuitira kuti application ikwanise kushanda. Munguva yekutanga kwese, hapana kana network inodzima.
Chekupedzisira, Kuongorora musimboti wekushandiswa kweBypass
1. Dhigirii remidziyo
Padanho rehardware, relay inonyanya kushandiswa kugadzira Bypass. Marelay aya anonyanya kubatanidzwa kutambo dzesignal dzenetwork port yega yega paBypass network port. Mufananidzo unotevera unoshandisa tambo imwe chete yesignal kuratidza mashandiro erelay.
Semuenzaniso, tora power trigger. Kana simba rikatadza kushanda, switch iri mu relay ichasvika pa 1, kureva kuti, Rx iri muRJ45 port yeLAN1 inosangana zvakananga neRJ45 Tx yeLAN2. Kana mudziyo wabatidzwa, switch yacho ichabatana ne2. Unofanira kuita izvozvo uchishandisa app iri pamudziyo uyu.
2. Chikamu cheSoftware
Muchikamu cheBypass, GPIO neWatchdog zvinokurukurwa kuti zvidzore uye zvitange Bypass. Kutaura zvazviri, nzira idzi dzese dzinoshandisa GPIO, uye GPIO inodzora relay iri pahardware kuti iite kusvetuka kwakakodzera. Kunyanya, kana GPIO inoenderana yakaiswa pakakwirira, relay ichasvetuka kuenda panzvimbo 1. Kusiyana neizvi, kana GPIO cup yakaiswa pakaderera, relay ichasvetuka kuenda panzvimbo 2.
Kune Watchdog Bypass, kutaura chokwadi, zvichibva pane zviri pamusoro apa GPIO control, wedzera Watchdog control Bypass. Mushure mekunge watchdog yatanga kushanda, isa chiito chekupfuura muBIOS. Sisitimu iyi inogonesa Watchdog function. Mushure mekunge Watchdog yatanga kushanda, network port Bypass inoenderana inogoneswa, zvichiita kuti mudziyo uve muBypass state. Kutaura chokwadi, Bypass inodzorwawo neGPIO. Muchiitiko ichi, kunyora kwakaderera kuGPIO kunoitwa neWatchdog, uye hapana imwe programming inodiwa kuti unyore GPIO.
Basa reHardware Bypass ibasa rinodiwa pazvigadzirwa zvekuchengetedza network. Kana mudziyo wadzimwa kana kukanganiswa, maports emukati neekunze anogona kubatanidzwa kuti agadzire network cable. Nenzira iyi, data traffic yevashandisi inogona kupfuura nemumudziyo pasina kukanganiswa nemamiriro aripo emudziyo.
