Kuti uongorore traffic trett, inodikanwa kutumira iyo Network packet kuenda kuNtow / nprobe kana kunze-kwe-bhendi network nekuchengetedzeka network. Pane mhinduro mbiri kune iri dambudziko:
Portunganidza(zvakare anozivikanwa sepasina
Network tap.
Usati watsanangura mutsauko pakati pemhinduro mbiri (port girazi uye network tap), zvakakosha kuti unzwisise kuti Ehernet inoshanda sei. At 100Mmbit uye pamusoro, host hols kazhinji totaura mune yakazara duplex, zvichireva kuti mumwe mugamuchiri anogona kutumira (TX) uye gamuchira (rx) panguva imwe chete. Izvi zvinoreva kuti pane 100 Mbit Cable yakabatana kune imwe host, iyo huwandu hwenhandare yetiweki iyo imwe inobata inogona kutumira / gamuchira (TX / RX) ndeye 2 × 100 MBIT = 200 MBIT.
Iyo port corming iri kushanda packet replication, zvinoreva kuti iyo network mudziyo mumuviri une mutoro wekutevedzera packet kune chiteshi chegirazi.
Izvi zvinoreva kuti mudziyo unofanirwa kuita iri basa nekushandisa rimwe sosi (senge cpu), uye zvese zvevatungamiriri zvemigwagwa zvichadzokororwa kuchiteshi chimwe chete. Sezvambotaurwa, mune yakazara Duplex link, izvi zvinoreva kuti
A -> B uye B -> A
Uwandu hwehucha usingapfuure iyo network yekumhanyisa isati yarasikirwa paPaketi yekupera. Izvi zvinodaro nekuti pane nzvimbo yemuviri isina nzvimbo yekutevedzera mapaketi. Zvinozoitika kuti chiteshi chechitima chikuru chehunyanzvi sezvazvinogona kuitwa neyakawoneka. Kwete kutaura kuti Packet girazi ingangoda kuchinjanisa switches zviwanikwa, izvo zvinogona kutakura mudziyo uye kukonzera kushandurwa kuita kushatisa. Ziva kuti iwe unogona kubatanidza 1 chiteshi chimwe nechiteshi chimwe, kana 1 vlan kune chimwe chiteshi, asi iwe kazhinji haugone kutevedzera manyorisi mazhinji kusvika 1. (Saka segirazi rePaketi) isipo.
Iyo Tap Tap (Terminal Access Point)ishandare yakakwana yechigaro, iyo inogona kungobata traffic pane network. Zvinowanzojairwa kutarisa traffic pakati pemapepa maviri mune network. Kana iyo network pakati peiyi mapoinzi maviri ane tambo yemuviri, tapeti network inogona kunge iri nzira yakanaka yekubata traffic.
Iyo teti network ine kanenge katatu zviteshi: chiteshi, ye0 chiteshi, uye chiteshi chechiteshi. Kuti uise tapuriti pakati pemativi A uye B, iyo network network pakati pekunongedza neyakaitwa nembongoro, imwe ichiputira piteshi, imwe yacho inoenda kuTap's B Port. Iyo tap inopfuudza traffic yese pakati pematanho maviri network, saka ivo vakabatana kune mumwe nemumwe. Iyo tap iyo zvakare inoteedzera traffic kune yayo yekutarisa chiteshi, nekudaro ichigonesa chishandiso chekuongorora kuti titeerere.
Network Taps inowanzo shandiswa nekutarisa uye kuunganidza midziyo yakadai seAPS. Matipi anogona zvakare kushandiswa mune yekuchengetedza mashandiro nekuti ivo havasvike pane network, vanogona kubata neine yakazara-dura-dura-kuburikidza neyekupaza traffic kunyangwe iyo tapu ichimira kushanda kana kurasa simba.
Sezvo network taps zviteshi hazvigamuchire asi kuendesa chete, iyo switch haina chirevo icho chakagara kuseri kwemachira. Mhedzisiro ndeyekuti iyo yakaparadzira mapaketi kumachiteshi ese. Naizvozvo, kana iwe ukabatanidza yako yekutarisa mudziyo kune switch, dhizaini yakadaro ichagamuchira mapaketi ese. Ziva kuti iyi mechanism inoshanda kana mudziyo wekutarisa usingatumire chero mapaketi kusvika pakuchinjika; Zvikasadaro, switch ichafungidzira kuti mapaketi akamhara haasi emhando yakadaro. Kuti uzadzise izvo, unogona kushandisa network netambo iyo iwe yausina kubatanidza waya yeTX, kana kushandisa ip-shoma (uye DHCP-zvishoma) network interface isingaendere mapaketi zvachose. Pakupedzisira ita kuti kana iwe uchida kushandisa tap yekusaita mapaketi, saka usingashandise mafambiro kana switm
Saka, sei kubata network network? Network Taps vs switch purts girazi
1- Easy Kugadziriswa: Network Tap> Port Mirror
2- Network Performance Property: Network Tap <Port Mirror
3- Tora, Kudzokorora, Aggregation, Kuendesa Kugona: Network Tap> Port Girazi
4- traffic yekutumira latency: network tap <port girazi
5- traffic preprocessing capacity: network tap> port girazi
