Lub Bypass TAP (tseem hu ua lub bypass switch) muab cov chaw nkag mus rau qhov tsis ua haujlwm rau cov khoom siv ruaj ntseg uas nyob hauv lub network xws li IPS thiab cov firewalls tiam tom ntej (NGFWS). Lub bypass switch no raug xa mus rau nruab nrab ntawm cov khoom siv network thiab nyob rau pem hauv ntej ntawm cov cuab yeej ruaj ntseg network kom muab qhov chaw sib cais ntawm lub network thiab txheej kev ruaj ntseg. Lawv coj kev txhawb nqa tag nrho rau cov network thiab cov cuab yeej ruaj ntseg kom tsis txhob muaj kev pheej hmoo ntawm kev tsis ua haujlwm ntawm lub network.
Kev daws teeb meem 1 1 Txuas Bypass Network Tap (Bypass Switch) - Ywj pheej
Daim Ntawv Thov:
Lub Bypass Network Tap (Bypass Switch) txuas rau ob lub cuab yeej network los ntawm Link ports thiab txuas rau lub server thib peb los ntawm Device ports.
Qhov pib ntawm Bypass Network Tap (Bypass Switch) tau teeb tsa rau Ping, uas xa cov lus thov Ping mus rau lub server. Thaum lub server tsis teb rau pings, Bypass Network Tap (Bypass Switch) nkag mus rau hom bypass.
Thaum lub server pib teb dua, Bypass Network Tap (Bypass Switch) hloov rov qab mus rau hom throughput.
Daim ntawv thov no tsuas yog ua haujlwm tau los ntawm ICMP (Ping). Tsis muaj lub plawv dhia pob khoom siv los saib xyuas kev sib txuas ntawm lub server thiab Bypass Network Tap (Bypass Switch).
Kev daws teeb meem 2 Network Packet Broker + Bypass Network Tap (Bypass Switch)
Network Packet Broker (NPB) + Bypass Network Tap (Bypass Switch) -- Qhov xwm txheej ib txwm muaj
Daim Ntawv Thov:
Lub Bypass Network Tap (Bypass Switch) txuas rau ob lub cuab yeej network los ntawm Link ports thiab rau Network Packet Broker (NPB) los ntawm Device ports. Lub server sab nraud txuas rau Network Packet Broker (NPB) siv 2 x 1G tooj liab cables. Network Packet Broker (NPB) xa cov heartbeat packets mus rau lub server los ntawm port #1 thiab xav tau txais lawv dua ntawm port #2.
Tus trigger rau Bypass Network Tap (Bypass Switch) tau teeb tsa rau REST, thiab Network Packet Broker (NPB) khiav daim ntawv thov bypass.
Tsheb khiav hauv hom kev xa khoom:
Cuab Yeej 1 ↔ Hloov Pauv/Kaw ↔ NPB ↔ Server ↔ NPB ↔ Hloov Pauv/Kaw ↔ Cuab Yeej 2
Network Packet Broker (NPB) + Bypass Network Tap (Bypass Switch) -- Software Bypass
Kev piav qhia txog Software Bypass:
Yog tias Network Packet Broker (NPB) tsis pom cov pob ntawv heartbeat, nws yuav ua rau software bypass.
Qhov kev teeb tsa ntawm Network Packet Broker (NPB) raug hloov pauv kom xa cov tsheb khiav rov qab mus rau Bypass Network Tap (Bypass Switch), yog li rov ntxig cov tsheb khiav mus rau hauv qhov txuas nrog qhov poob pob tsawg kawg nkaus.
Lub Bypass Network Tap (Bypass Switch) tsis tas yuav teb txhua vim tias txhua qhov kev bypasses yog ua los ntawm Network Packet Broker (NPB).
Kev khiav tsheb hauv Software Bypass:
Ntaus 1 ↔ Hloov Pauv/Kaw ↔ NPB ↔ Hloov Pauv/Kaw ↔ Ntaus 2
Network Packet Broker (NPB) + Bypass Network Tap (Bypass Switch) -- Kho vajtse bypass
Kev piav qhia txog Kho Vajtse Bypass:
Yog tias Network Packet Broker (NPB) tsis ua haujlwm lossis kev sib txuas ntawm Network Packet Broker (NPB) thiab Bypass Network Tap (Bypass Switch) raug txiav tawm, Bypass Network Tap (Bypass Switch) hloov mus rau hom bypass kom qhov txuas ua haujlwm tiag tiag.
Thaum Bypass Network Tap (Bypass Switch) mus rau hauv hom bypass, Network Packet Broker (NPB) thiab lub server sab nraud raug bypassed thiab tsis tau txais cov tsheb khiav mus txog thaum Bypass Network Tap (Bypass Switch) hloov rov qab mus rau hom throughput.
Lub hom bypass raug qhib thaum Bypass Network Tap (Bypass Switch) tsis txuas nrog lub hwj chim lawm.
Cov khoom siv hluav taws xob tawm ntawm txoj kab tsheb khiav:
Ntaus 1 ↔ Hloov/Kais hla ↔ Ntaus 2
Kev daws teeb meem 3 Ob lub Bypass Network Taps (Bypass Switches) rau txhua qhov txuas
Cov lus qhia txog kev teeb tsa:
Hauv qhov kev teeb tsa no, 1 qhov txuas tooj liab ntawm 2 lub cuab yeej txuas nrog lub server paub raug hla los ntawm ob lub Bypass Network Taps (Bypass Switches). Qhov zoo ntawm qhov no dhau ntawm 1 qhov kev daws teeb meem bypass yog tias thaum kev sib txuas ntawm lub network packet broker (NPB) raug cuam tshuam, lub server tseem yog ib feem ntawm qhov txuas nyob.
2 * Bypass Network Taps (Bypass Switches) ib qhov txuas - Software Bypass
Kev piav qhia txog Software Bypass:
Yog tias Network Packet Broker (NPB) tsis pom cov pob ntawv heartbeat, nws yuav ua rau software bypass. Lub Bypass Network Tap (Bypass Switch) tsis tas yuav teb txhua vim tias txhua qhov bypasses yog ua los ntawm Network Packet Broker (NPB).
Kev khiav tsheb hauv software bypass:
Ntaus 1 ↔ Hloov Pauv/Kais 1 ↔ Tus Neeg Saib Xyuas Pob Khoom Hauv Network (NPB) ↔ Hloov Pauv/Kais 2 ↔ Ntaus 2
2 * Bypass Network Taps (Bypass Switches) ib qhov txuas - Hardware Bypass
Kev piav qhia txog Kho Vajtse Bypass:
Yog tias Network Packet Broker (NPB) tsis ua haujlwm lossis kev sib txuas ntawm Bypass Network Tap (Bypass Switch) thiab Network Packet Broker (NPB) raug txiav tawm, ob qho Bypass Network Taps (Bypass Switches) raug hloov mus rau hom bypass kom tswj tau qhov txuas nquag.
Tsis zoo li qhov chaw teeb tsa "1 Bypass per link", lub server tseem suav nrog hauv qhov txuas nyob.
Cov khoom siv hluav taws xob tawm ntawm txoj kab tsheb khiav:
Ntaus 1 ↔ Hloov Pauv/Kais 1 ↔Server ↔ Hloov Pauv/Kais 2 ↔ Ntaus 2
Kev daws teeb meem 4 Ob lub Bypass Network Taps (Bypass Switches) tau teeb tsa rau txhua qhov txuas ntawm ob qhov chaw
Cov lus qhia teeb tsa:
Yeem xaiv tau: Ob lub Network Packet Brokers (NPBs) siv tau los txuas ob lub chaw sib txawv hla lub GRE tunnel es tsis yog ib lub Network Packet Broker (NPB). Yog tias lub server txuas ob lub chaw tsis ua haujlwm, nws yuav hla lub server thiab cov tsheb khiav uas tuaj yeem faib tawm los ntawm lub GRE tunnel ntawm Network Packet Broker (NPB) (raws li pom hauv cov duab hauv qab no).
