TAPs (Test Access Points), inozivikanwawo se inozivikanwawo seReplication Tap, Aggregation Tap, Active Tap, Copper Tap, Ethernet Tap, Optical Tap, Physical Tap, etc. Matepi inzira yakakurumbira yekutora network data. Ivo vanopa kuoneka kwakazara mukati metiweki data inoyerera uye kunyatso tarisa bidirectional nhaurirano nekuzara mutsetse kumhanya, pasina kurasikirwa kwepaketi kana latency. Kubuda kweTAPs kwakasandura ndima yekutarisa nekutarisa network, zvakanyanya kushandura nzira dzekuwana dzekutarisa nekuongorora masisitimu uye nekupa yakakwana uye inochinjika mhinduro kune yese yekutarisa system.
Ikozvino budiriro yetekinoroji yakagadzira mhando dzakasiyana dzemapombi: matepi anounganidza akawanda malink, matepi ekuvandudza anotsemura traffic yekubatanidza muzvikamu zvakati wandei, bypass tap, uye matrix tap switch.
Parizvino, iwo anonyanya kufarirwa mabhureki eTap muindastiri anosanganisira NetTAP uye Mylinking, pakati payo Mylinking inozivikanwa seyakanakisa Tap uye NPB mhando muindasitiri yeChinese, ine yakakwira musika mugove, kugadzikana uye kuita kwakanaka.
Zvakanakira zveTAP
1. Bata 100% yemapakiti e data pasina kurasikirwa kwepakiti.
2. Irregular data packets inogona kuongororwa, kufambisa kugadzirisa matambudziko.
3. Chaiyo timestamps, hapana kunonoka uye retiming.
4. Kuiswa kwekamwe-nguva kunoita kuti zvive nyore kubatanidza uye kufambisa analyzer.
Zvakaipa zveTAP
1. Unoda kushandisa mari yakawedzerwa kutenga splitter TAP, iyo inodhura uye inotora nzvimbo ye rack.
2. Chibatanidza chimwe chete chinogona kutariswa panguva.
Mashandisirwo Akajairika eTAP
1. Commercial links: Izvi zvinongedzo zvinoda nguva pfupi yekupedza matambudziko. Nekuisa maTAP mune izvi zvinongedzo, mainjiniya etiweki anogona kukurumidza kutsvaga uye kugadzirisa matambudziko kamwe kamwe.
2. Core kana backbone links. Aya ane mashandisirwo akakwira bandwidth uye haagone kukanganiswa kana uchibatanidza kana kufambisa analyzer. TAP inovimbisa 100% data kutorwa pasina kurasikirwa kwepaketi, ichipa vimbiso yekushanda kwekuongorora kwakaringana kweizvi zvinongedzo.
3. VoIP neQoS: VoIP yehutano hwekuongororwa kwebasa inoda jitter yakarurama uye zviyero zvekurasikirwa kwepakiti. MaTAP anovimbisa zvizere bvunzo idzi, asi magirazi echiteshi anogona kushandura jitter maitiro uye kupa zvisingaite packet kurasikirwa mitengo.
4. Kugadzirisa dambudziko: Ita shuwa kuti zvisizvo uye zvisiri izvo data packets zvakaonekwa. Mirrored ports inosefa kunze aya mapaketi, kudzivirira mainjiniya kubva pakupa yakakosha uye yakazara data ruzivo rwekugadzirisa matambudziko.
5. IDS application: IDS inovimba neruzivo rwakakwana rwe data kuti ione maitiro ekupinda, uye TAP inogona kupa yakavimbika uye yakazara data hova kune intrusion yekuona system.
6. Server cluster: Iyo yakawanda-port splitter inogona kubatanidza 8/12 links panguva imwe chete, ichigonesa kure uye yakasununguka switching, izvo zviri nyore kutarisa uye kuongorora chero nguva.
SPAN (Chinja Port Analysis)inozivikanwawo seMirrored Port kana Port Mirror. Kuchinja kwepamusoro kunogona kukopa mapepa e data kubva kune imwe kana kupfuura kune imwe nzvimbo yakasarudzwa, inonzi "mirror port" kana "chiteshi chekuenda." Analyzer inogona kubatana kune yakamisikidzwa chiteshi kuti igamuchire data. Nekudaro, iyi ficha inogona kukanganisa chinja mashandiro uye kukonzera kurasikirwa kwepaketi kana data yaremerwa.
Zvakanakira zveSPAN
1. Economical, hapana imwe midziyo inodiwa.
2. Yese traffic paVLAN pane switch inogona kutariswa panguva imwe chete.
3. Imwe analyzer inogona kutarisa akawanda ma link.
Zvakaipa zveSPAN
1. Mirroring traffic kubva kune dzakawanda zviteshi kuenda kune imwe chiteshi kunogona kukonzera cache kuwandisa uye kurasikirwa kwepaketi.
2. Mapakiti anodzokororwa sezvaanopfuura nepakati, zvichiita kuti zvisakwanise kunyatsoona zviyero zvenguva sejitter, packet interval analysis, uye latency.
3. Haikwanise kutarisa OSI layer 1.2 kukanganisa mapaketi. Mazhinji data mirroring ports anosefa kunze zvisina kujairika data pakiti, izvo zvisingakwanise kupa yakadzama uye inobatsira data ruzivo rwekugadzirisa matambudziko.
4. Nekuti traffic yechiteshi chemiratidzo inowedzera CPU mutoro wekuchinja, zvinokonzeresa kuti shanduko iite kudzikira.
Yakajairika Mashandisirwo eSPAN
1. Kune zvinongedzo zvine yakaderera bandwidth uye yakanaka girazi kugona, multi-port mirroring inogona kushandiswa kuchinjika kuongorora uye kutarisa.
2. Trend monitoring: Kana kunyatsotarisisa kusingade, chete zvisina kujairika data statistics inokwana.
3. Protocol uye kuongororwa kwemashandisirwo: ruzivo rwe data rwakakodzera runogona kupihwa zviri nyore uye zvine hupfumi kubva pagirazi chiteshi
4. Yese VLAN monitoring: Multi-port mirroring tekinoroji inogona kushandiswa kutarisa nyore VLAN yese pane switch.
Nhanganyaya kuVLAN:
Chekutanga, ngatizivise iyo yakakosha pfungwa yenhepfenyuro. Izvi zvinoreva huwandu huri mukati meiyo nhepfenyuro mafuremu (ekuenda MAC kero ese ari 1) anogona kufambiswa, uye nemamwe mazwi, chiyero mukati umo kutaurirana kwakananga kunogoneka. Kunyatsotaura, kwete chete nhepfenyuro mafuremu, asiwo multicast mafuremu uye isingazivikanwe unicast mafuremu anogona kufamba akasununguka mukati meiyo imwechete nhepfenyuro.
Pakutanga, Layer 2 switch yaingokwanisa kumisa imwechete nhepfenyuro. PaLayer 2 switch isina chero maVLAN akagadziriswa, chero nhepfenyuro yaizoendeswa kune ese madoko kunze kwechiteshi chekugamuchira (mafashamo). Nekudaro, kushandisa maVLAN kunobvumira network kuti igovane mumatunhu akawanda ekutepfenyura. VLANs ndiyo tekinoroji inoshandiswa kupatsanura nhepfenyuro paLayer 2 switch. Nekushandisa maVLAN, tinokwanisa kugadzira zvakasununguka kuumbwa kwemasitepfenyuro, tichiwedzera kuchinjika kwekugadzira network.
