Mylinking™ Network Bypass TAPs hamwe n'ikoranabuhanga rya heartbeat ritanga umutekano wa network mu gihe nyacyo ritabangamiye ubwizigirwa cyangwa uburyo bwo kuboneka kwa network. Mylinking™ Network Bypass TAPs hamwe na module ya 10/40/100G Bypass itanga imikorere yihuta cyane ikenewe kugira ngo uhuze ibikoresho by'umutekano kandi urinde urujya n'uruza rw'itumanaho mu gihe nyacyo nta gutakaza paki.
Ubwa mbere, Bypass ni iki?
Muri rusange, igikoresho cy’umutekano w’umuyoboro gikoreshwa hagati y’imiyoboro ibiri cyangwa myinshi, nka Intranet n’umuyoboro wo hanze. Porogaramu y’ibikorwa ku gikoresho cy’umutekano w’umuyoboro isesengura paki z’umuyoboro kugira ngo imenye niba hari ibibazo, hanyuma yohereza paki hakurikijwe amategeko amwe n’amwe agenga inzira. Iyo igikoresho cy’umutekano w’umuyoboro gifite ikibazo, Urugero, nyuma y’ibura ry’amashanyarazi cyangwa impanuka, ibice by’umuyoboro bihujwe n’igikoresho bizabura aho bihurira. Muri iki gihe, niba buri muyoboro ukeneye guhuzwa, ugomba kuba unyura imbere.
Bypas, nk'uko izina ribisobanura, ni imikorere ya bypassed, bivuze ko imiyoboro ibiri ishobora kunyuzwa mu buryo butaziguye muri sisitemu y'igikoresho cy'umutekano w'umuyoboro binyuze mu buryo bwihariye bwo gutera (gucika kw'amashanyarazi cyangwa kuzimya). Nyuma y'uko Bypass ifunguye, iyo igikoresho cy'umutekano w'umuyoboro kinaniwe, umuyoboro uhujwe n'igikoresho cya bypass ushobora kuvugana. Muri iki gihe, igikoresho cya bypass ntigitunganya amapaki kuri urubuga.
Icya kabiri, ishyirwa mu byiciro rya Bypass rikoreshwa muri ubu buryo bukurikira:
Uburyo bwo gucishamo (Bypass) bugabanyijemo uburyo bukurikira: uburyo bwo kugenzura cyangwa uburyo bwo gutangira
1. Biterwa n'amashanyarazi. Muri ubu buryo, imikorere ya Bypass irafunguka iyo igikoresho kidafunguye. Iyo igikoresho gifunguye, Bypass ihita izimwa.
2. Igenzurwa na GPIO. Nyuma yo kwinjira muri OS, ushobora gukoresha GPIO kugira ngo ukoreshe imiyoboro yihariye kugira ngo ugenzure switch ya Bypass.
3, hakoreshejwe uburyo bwa Watchdog. Ubu ni uburyo bwo kongeramo uburyo bwa 2. Ushobora gukoresha Watchdog kugira ngo ugenzure uburyo bwo gufungura no gufunga porogaramu ya GPIO Bypass, kugira ngo ugenzure uburyo bwa Bypass. Muri ubu buryo, Bypass ishobora gufungurwa na Watchdog mu gihe urubuga rwangiritse.
Mu bikorwa bifatika, izi mimerere itatu zikunze kubaho icyarimwe, cyane cyane inzira ebyiri za 1 na 2. Uburyo rusange bwo gukoresha ni ubu: Iyo igikoresho kizimye, Bypass iba ifunguye. Iyo igikoresho kimaze gufunguka, BIOS ishobora gukoresha Bypass. Iyo BIOS imaze gufata igikoresho, Bypass iba ikomeje gufunguka. Bypass irazimye kugira ngo porogaramu ibashe gukora. Mu gihe cyose cyo gutangira, nta gusiba umuyoboro wa interineti bibaho.
Icya nyuma, Isesengura ry'ihame ryo gushyira mu bikorwa Bypass
1. Urwego rw'ibikoresho
Ku rwego rw'ibikoresho, relay ikoreshwa cyane cyane mu gukora Bypass. Izi relay zihujwe cyane cyane n'insinga z'ibimenyetso za buri muyoboro w'itumanaho kuri Bypass network port. Ishusho ikurikira ikoresha insinga imwe y'ibimenyetso kugira ngo igaragaze uburyo relay ikora.
Fata urugero rw'ingufu z'amashanyarazi. Mu gihe umuriro wabuze, switch iri muri relay izagera kuri 1, ni ukuvuga ko Rx iri muri port ya RJ45 ya LAN1 ikorana na RJ45 Tx ya LAN2. Iyo igikoresho gifunguye, switch izahuza na 2. Ugomba kubikora ukoresheje porogaramu iri kuri iki gikoresho.
2. Urwego rwa porogaramu
Mu gushyira mu byiciro Bypass, GPIO na Watchdog biraganirwaho kugira ngo bigenzure kandi bitere Bypass. Mu by'ukuri, ubu buryo bwombi bukoresha GPIO, hanyuma GPIO ikagenzura relay iri ku bikoresho kugira ngo ikore gusimbuka bihuye. By'umwihariko, niba GPIO ijyanye nayo ishyizwe hejuru, relay izasimbuka ijya ku mwanya wa 1. Ku rundi ruhande, niba igikombe cya GPIO gishyizwe hasi, relay izasimbuka ijya ku mwanya wa 2.
Kuri Watchdog Bypass, mu by'ukuri, hashingiwe ku igenzura rya GPIO ryavuzwe haruguru, ongeramo Watchdog control Bypass. Nyuma yuko watchdog itangiye gukora, shyira igikorwa cyo kunyura muri BIOS. Sisitemu ituma Watchdog ikora. Nyuma yuko Watchdog itangiye gukora, umuyoboro wa interineti ujyanye na Bypass urafunguka, bigatuma igikoresho kiba muri Bypass. Mu by'ukuri, Bypass nayo igenzurwa na GPIO. Muri iki gihe, kwandika GPIO ku rwego rwo hasi bikorwa na Watchdog, kandi nta porogaramu y'inyongera isabwa kugira ngo wandike GPIO.
Igikorwa cya "hardware Bypass" ni imikorere ikenewe ku bikoresho by'umutekano wa interineti. Iyo igikoresho kizimye cyangwa gihagaritswe, imiyoboro y'imbere n'iy'inyuma ishobora guhuzwa mu buryo bufatika kugira ngo habeho insinga y'itumanaho. Muri ubu buryo, urujya n'uruza rw'amakuru rw'abakoresha rushobora kunyura muri igikoresho nta ngaruka bigira ku miterere y'igikoresho ubu.
