Ma Mylinking™ Network Bypass TAP okhala ndi ukadaulo wakugunda kwamtima amapereka chitetezo pamanetiweki munthawi yeniyeni popanda kusiya kudalirika kapena kupezeka kwa netiweki. Mylinking™ Network Bypass TAPs yokhala ndi gawo la 10/40/100G Bypass imapereka magwiridwe antchito othamanga kwambiri ofunikira kuti alumikizane ndi zida zachitetezo ndikuteteza kuchuluka kwa maukonde munthawi yeniyeni popanda kutayika kwa paketi.
Choyamba, Bypass ndi chiyani?
Nthawi zambiri, chipangizo chotetezera maukonde chimagwiritsidwa ntchito pakati pa maukonde awiri kapena angapo, monga Intranet ndi netiweki yakunja. Pulogalamu yogwiritsira ntchito pa chipangizo chachitetezo cha netiweki imasanthula mapaketi a netiweki kuti adziwe ngati ziwopsezo zilipo, kenako zimatumiza mapaketiwo molingana ndi malamulo ena oyendetsera. Ngati chipangizo chachitetezo cha maukonde ndi cholakwika, mwachitsanzo, mphamvu ikatha kapena kuwonongeka, magawo a netiweki olumikizidwa ndi chipangizocho adzataya kukhudzana. Panthawiyi, ngati intaneti iliyonse ikufunika kulumikizidwa wina ndi mzake, iyenera kukhala Bypass patsogolo.
Bypas, monga dzina limatanthawuzira, ndi ntchito yolambalalitsidwa, zomwe zikutanthauza kuti maukonde awiri akhoza kuyendetsedwa mwachindunji kudzera mu dongosolo la chitetezo cha intaneti kudzera mumtundu wina woyambitsa (kulephera kwa mphamvu kapena kutseka). Pambuyo poyatsira Bypass, chipangizo chachitetezo cha intaneti chikalephera, maukonde olumikizidwa ndi chipangizo chodutsa amatha kulumikizana wina ndi mnzake. Pankhaniyi, chipangizo cholambalala sichikonza mapaketi pamaneti.
Chachiwiri, gulu la Bypass limagwiritsidwa ntchito motere:
Bypass imagawidwa m'njira zotsatirazi: mode control kapena trigger mode
1. Kuyambitsidwa ndi magetsi. Munjira iyi, ntchito ya Bypass imayatsidwa pomwe chipangizocho sichinayatsidwe. Chipangizocho chikayatsidwa, Bypass imazimitsidwa nthawi yomweyo.
2. Kulamulidwa ndi GPIO. Mukalowa mu OS, mutha kugwiritsa ntchito GPIO kugwiritsa ntchito madoko ena kuti muwongolere kusintha kwa Bypass.
3, ndi Watchdog control. Izi ndizowonjezera Njira 2. Mungagwiritse ntchito Watchdog kuti muyang'ane ndikuletsa pulogalamu ya GPIO Bypass, kuti muwongolere mawonekedwe a Bypass. Mwanjira iyi, Bypass ikhoza kutsegulidwa ndi Watchdog ngati nsanja ikugwa.
Muzogwiritsira ntchito, maiko atatuwa nthawi zambiri amakhalapo nthawi imodzi, makamaka njira ziwiri 1 ndi 2. Njira yogwiritsira ntchito ndi: Pamene chipangizocho chazimitsidwa, Bypass imayatsidwa. Chipangizocho chikayatsidwa, BIOS imatha kugwiritsa ntchito Bypass. BIOS ikatenga chipangizocho, Bypass ikadalipo. Bypass imazimitsidwa kuti pulogalamuyo igwire ntchito. Panthawi yonse yoyambira, palibe kulumikizidwa kwa netiweki.
Pomaliza, Kusanthula kwa mfundo yoyendetsera Bypass
1. Mulingo wa zida
Pamlingo wa Hardware, relay imagwiritsidwa ntchito kwambiri kuzindikira Bypass. Ma relay awa amalumikizidwa makamaka ndi zingwe zolumikizira pa doko lililonse la netiweki pa doko la Bypass network. Chithunzi chotsatirachi chimagwiritsa ntchito chingwe chimodzi cha siginecha kuwonetsa momwe ntchito yolumikizirana imagwirira ntchito.
Tengani choyambitsa mphamvu monga chitsanzo. Pankhani ya kulephera kwa mphamvu, chosinthira mu relay chidzalumphira ku 1, ndiko kuti, Rx mu doko la RJ45 la LAN1 imalankhulana mwachindunji ndi RJ45 Tx ya LAN2. Pamene chipangizochi chikugwiritsidwa ntchito, chosinthira chidzagwirizanitsa ku 2. Muyenera kutero kudzera mu pulogalamu pa chipangizo ichi.
2. Mapulogalamu apamwamba
Pagulu la Bypass, GPIO ndi Watchdog amakambidwa kuti aziwongolera ndikuyambitsa Bypass. M'malo mwake, njira zonsezi zimagwiritsa ntchito GPIO, ndiyeno GPIO imayang'anira kutumizirana ma hardware kuti idumphe. Mwachindunji, ngati GPIO yofananira yayikidwa pamwamba, ndiye kuti relay idzalumphira ku malo 1. Mosiyana ndi zimenezi, ngati chikho cha GPIO chatsitsidwa, relay idzalumphira kumalo a 2.
Kwa Watchdog Bypass, makamaka, pamaziko a GPIO yomwe ili pamwambayi, onjezani Watchdog control Bypass. Woyang'anira akayamba kugwira ntchito, ikani zomwe zichitike kuti zidutse mu BIOS. Dongosolo limathandizira ntchito ya Watchdog. Pambuyo pa Watchdog ikuyamba kugwira ntchito, doko lofananira la netiweki limayatsidwa, ndikupanga chipangizocho kukhala Bypass state. M'malo mwake, Bypass imayendetsedwanso ndi GPIO. Pankhaniyi, kulembera kwapansi kwa GPIO kumachitidwa ndi Watchdog, ndipo palibe mapulogalamu owonjezera omwe amafunikira kuti alembe GPIO.
Ntchito ya Hardware Bypass ndi ntchito yofunikira pazachitetezo chapaintaneti. Chipangizocho chikazimitsidwa kapena kusokonezedwa, madoko amkati ndi akunja amatha kulumikizidwa wina ndi mnzake kuti apange chingwe cha netiweki. Mwanjira iyi, kuchuluka kwa data kwa ogwiritsa ntchito kumatha kudutsa chipangizocho popanda kukhudzidwa ndi momwe chipangizocho chilili.
