Tayoyin Mylinking™ Network Bypass tare da fasahar bugun zuciya suna ba da tsaron cibiyar sadarwa na ainihin lokaci ba tare da yin watsi da amincin hanyar sadarwa ko samuwa ba. Tayoyin Mylinking™ Network Bypass tare da module na 10/40/100G Bypass suna ba da babban aikin da ake buƙata don haɗa kayan aikin tsaro da kare zirga-zirgar hanyar sadarwa a ainihin lokaci ba tare da asarar fakiti ba.
Da farko, menene Bypass?
Gabaɗaya, ana amfani da na'urar tsaro ta hanyar sadarwa tsakanin hanyoyin sadarwa biyu ko fiye, kamar Intanet da hanyar sadarwa ta waje. Shirin aikace-aikacen da ke kan na'urar tsaro ta hanyar sadarwa yana nazarin fakitin hanyar sadarwa don tantance ko akwai barazanar, sannan ya tura fakitin bisa ga wasu ƙa'idodin hanya. Idan na'urar tsaro ta hanyar sadarwa ta lalace, Misali, bayan gazawar wutar lantarki ko faɗuwa, sassan hanyar sadarwa da aka haɗa da na'urar za su rasa hulɗa da juna. A wannan lokacin, idan kowace hanyar sadarwa tana buƙatar haɗawa da juna, dole ne ta kasance gaba gaba.
Kamar yadda sunan ya nuna, Bypas aiki ne da aka yi wa katanga, wanda ke nufin cewa ana iya tura hanyoyin sadarwa guda biyu kai tsaye ta hanyar tsarin na'urar tsaron cibiyar sadarwa ta hanyar wani takamaiman yanayin kunna (kashe wutar lantarki ko kashewa). Bayan an kunna Bypass, lokacin da na'urar tsaron cibiyar sadarwa ta gaza, hanyar sadarwar da aka haɗa da na'urar bypass za ta iya sadarwa da juna. A wannan yanayin, na'urar bypass ba ta sarrafa fakiti a kan hanyar sadarwa.
Na biyu, ana amfani da rarraba Bypass ta hanyoyi kamar haka:
An raba kewaye zuwa waɗannan hanyoyi: yanayin sarrafawa ko yanayin jawowa
1. Wutar lantarki ce ke haifar da ita. A wannan yanayin, ana kunna aikin wucewa idan na'urar ba ta kunna ba. Idan na'urar ta kunna, nan take za a kashe hanyar wucewa.
2. Ana sarrafa shi ta hanyar GPIO. Bayan shiga cikin tsarin aiki, zaka iya amfani da GPIO don sarrafa takamaiman tashoshin jiragen ruwa don sarrafa maɓallin wucewa.
3, ta hanyar sarrafa Watchdog. Wannan ƙari ne na Hanyar 2. Kuna iya amfani da Watchdog don sarrafa kunnawa da kashe shirin GPIO Bypass, don sarrafa matsayin Bypass. Ta wannan hanyar, Watchdog zai iya buɗe Bypass idan dandamalin ya faɗi.
A aikace-aikacen aikace-aikace, waɗannan yanayi uku galibi suna wanzuwa a lokaci guda, musamman hanyoyi biyu na 1 da 2. Hanyar aikace-aikacen gabaɗaya ita ce: Lokacin da na'urar ta kashe, ana kunna Bypass. Bayan an kunna na'urar, BIOS zai iya sarrafa Bypass. Bayan BIOS ta karɓi na'urar, Bypass har yanzu yana kunne. Ana kashe Bypass don aikace-aikacen ya yi aiki. A duk lokacin fara aiki, kusan babu katsewar hanyar sadarwa.
A ƙarshe, Nazari kan ƙa'idar aiwatar da Bypass
1. Matakan kayan aiki
A matakin kayan aiki, ana amfani da relay galibi don cimma Bypass. Waɗannan relay galibi suna haɗuwa da kebul na sigina na kowace tashar sadarwa a tashar hanyar sadarwa ta Bypass. Hoto mai zuwa yana amfani da kebul na sigina ɗaya don nuna yanayin aikin relay.
A matsayin misali, idan aka sami matsalar wutar lantarki, maɓallin da ke cikin relay zai tashi zuwa 1, wato, Rx da ke cikin tashar RJ45 ta LAN1 yana sadarwa kai tsaye da RJ45 Tx na LAN2. Lokacin da aka kunna na'urar, maɓallin zai haɗu zuwa 2. Kuna buƙatar yin hakan ta hanyar app ɗin da ke kan wannan na'urar.
2. Matakan Software
A cikin rarrabuwar Bypass, an tattauna GPIO da Watchdog don sarrafawa da kuma haifar da Bypass. A zahiri, waɗannan hanyoyi guda biyu suna aiki da GPIO, sannan GPIO yana sarrafa relay akan kayan aikin don yin tsalle mai dacewa. Musamman, idan an saita GPIO mai dacewa zuwa sama, to relay zai tsalle zuwa matsayi na 1. Akasin haka, idan an saita kofin GPIO zuwa ƙasa, relay zai tsalle zuwa matsayi na 2.
A zahiri, ga Watchdog Bypass, bisa ga ikon sarrafa GPIO da ke sama, ƙara Watchdog control Bypass. Bayan mai lura ya fara aiki, saita aikin don wucewa a cikin BIOS. Tsarin yana ba da damar aikin Watchdog. Bayan Watchdog ya fara aiki, tashar hanyar sadarwa mai dacewa ta Bypass za ta kunna, wanda hakan ke sa na'urar ta kasance a cikin yanayin Bypass. A zahiri, GPIO kuma ke sarrafa Bypass. A wannan yanayin, Watchdog ne ke yin rubutu mai ƙarancin mataki zuwa GPIO, kuma ba a buƙatar ƙarin shirye-shirye don rubuta GPIO.
Aikin Kewaya Kayan Aiki (hardware Bypass) aiki ne mai mahimmanci na kayayyakin tsaro na cibiyar sadarwa. Idan na'urar ta kashe ko ta katse, za a iya haɗa tashoshin jiragen ruwa na ciki da na waje da juna don samar da kebul na cibiyar sadarwa. Ta wannan hanyar, zirga-zirgar bayanai na masu amfani za su iya wucewa ta na'urar ba tare da tasirin yanayin na'urar a yanzu ba.
