Ii-TAPs (Amanqaku okufikelela kuvavanyo), ekwabizwa ngokuba yiUkuphindaphinda ukucofa, Aggregation Tap, Itephu esebenzayo, Itephu yobhedu, Itephu ye-Ethernet, I-Optical Tap, Impompo yoMzimba, njl njl. Iimpompo yindlela edumileyo yokufumana idatha yenethiwekhi. Banikezela ngokubonakala okubanzi kwi-data yenethiwekhi kunye nokubeka iliso ngokuchanekileyo iingxoxo ze-bidirectional kwisantya esipheleleyo somgca, ngaphandle kokulahleka kwepakethi okanye i-latency. Ukuvela kwee-TAP kuguqule intsimi yokubeka iliso kwinethiwekhi kunye nokucupha, ngokusisiseko ukutshintsha iindlela zokufikelela kwiinkqubo zokubeka iliso kunye nokuhlalutya kunye nokubonelela ngesisombululo esipheleleyo nesiguquguqukayo kuyo yonke inkqubo yokubeka iliso.
Uphuhliso lwangoku lwetekhnoloji luvelise iintlobo ngeentlobo zempompo ezahlukeneyo: iitephu ezidibanisa amakhonkco amaninzi, iimpompo zokuvuselela ezahlula ikhonkco lekhonkco kwiindawo ezininzi, iimpompo ezidlulayo, kunye nokutshintsha kwempompo ye-matrix.
Okwangoku, ii-brand zeTap ezidumileyo kwishishini ziquka i-NetTAP kunye ne-Mylinking, phakathi kwayo i-Mylinking yamkelwa njengeTap egqwesileyo kunye ne-NPB brand kushishino lwaseTshayina, kunye nesabelo esikhulu semarike, ukuzinza kunye nokusebenza kakuhle.
Izinto ezilungileyo zeTAP
1. Thatha i-100% yeepakethi zedatha ngaphandle kokulahlekelwa kwepakethi.
2. Iipakethi zedatha ezingaqhelekanga zinokujongwa, ziququzelele ukuxazulula iingxaki.
3. Izitampu zexesha ezichanekileyo, akukho kulibaziseka kunye nokubuyisela ixesha.
4. Ukufakwa kwexesha elilodwa kwenza kube lula ukudibanisa nokuhambisa i-analyzer.
Ukungalungi kwe-TAP
1. Kufuneka uchithe imali eyongezelelweyo ukuthenga i-TAP eqhekezayo, ebiza kakhulu kwaye ithatha indawo yokubeka.
2. Ikhonkco elinye kuphela elinokujongwa ngexesha.
Usetyenziso oluqhelekileyo lwe-TAP
1. Amakhonkco orhwebo: La makhonkco afuna amaxesha amafutshane kakhulu okusombulula ingxaki. Ngokufakela ii-TAPs kula makhonkco, iinjineli zenethiwekhi zinokukhangela ngokukhawuleza kwaye zixazulule iingxaki ngequbuliso.
2. Ikhonkco okanye i-backbone links. Ezi zinosetyenziso oluphezulu lwe-bandwidth kwaye azikwazi ukuphazamiseka xa udibanisa okanye uhambisa i-analyzer. I-TAP iqinisekisa i-100% yokubanjwa kwedatha ngaphandle kokulahleka kwepakethi, ukubonelela ngesiqinisekiso sokusebenza sohlalutyo oluchanekileyo lwala makhonkco.
3. I-VoIP kunye ne-QoS: Umgangatho we-VoIP wovavanyo lwenkonzo ufuna i-jitter echanekileyo kunye nemilinganiselo yokulahlekelwa kwepakethi. Ii-TAP ziqinisekisa ngokupheleleyo olu mvavanyo, kodwa izibuko ezibonisiweyo zinokuwatshintsha amaxabiso e-jitter kwaye abonelele ngamaxabiso angafanelekanga epakethe yelahleko.
4. Ukusonjululwa kwengxaki: Qinisekisa ukuba iipakethi zedatha ezingekho mgaqweni nezinempazamo ziyabhaqwa. Izibuko ezibonisiweyo ziya kuhluza ezi pakethi, zithintele iinjineli ekuboneleleni ngolwazi olubalulekileyo nolupheleleyo lwedatha yokulungisa ingxaki.
5. Isicelo se-IDS: I-IDS ixhomekeke kulwazi olupheleleyo lwedatha ukuchonga iipatheni zokungena, kwaye i-TAP inokubonelela ngokuthembekileyo kunye nedatha epheleleyo kwiinkqubo zokufumanisa ukungena.
6. Iqela leseva: I-splitter ye-multi-port ingadibanisa i-8/12 izixhumanisi ngexesha elifanayo, ivumela ukutshintshwa okude kunye nokukhululekile, okukulungele ukubeka iliso kunye nokuhlalutya nangaliphi na ixesha.
I-SPAN (Tshintsha Uhlalutyo lwePort)ikwaziwa njengeSibuko esiMirrored okanye iPort Mirror. Ukutshintsha okuphezulu kunokukopa iipakethi zedatha ukusuka kwelinye okanye ngaphezulu kwizibuko elichongiweyo, elibizwa ngokuba yi "mirror port" okanye "indawo yokufikela." Umhlalutyi unokuqhagamshela kwizibuko elibonisiweyo ukuze afumane idatha. Nangona kunjalo, eli nqaku linokuchaphazela ukusebenza kokutshintsha kwaye kubangele ukulahleka kwepakethi xa idatha igcwele kakhulu.
Izinto eziluncedo ze-SPAN
1. Uqoqosho, akukho zixhobo ezongezelelweyo ezifunekayo.
2. Yonke i-traffic kwi-VLAN kwi-switch inokubekwa esweni ngaxeshanye.
3. Omnye umhlalutyi unokubeka iliso amakhonkco amaninzi.
Ukungalungi kwe-SPAN
1. Ukulinganisa i-traffic ukusuka kumazibuko amaninzi ukuya kwelinye i-port kunokubangela ukugqithiswa kwe-cache kunye nokulahlekelwa kwepakethi.
2. Iipakethi zihlaziywa kwakhona njengoko zidlula kwi-cache, okwenza kube nzima ukucacisa ngokuchanekileyo izikali zexesha ezifana ne-jitter, uhlalutyo lwekhefu lepakethi, kunye ne-latency.
3. Ayikwazi ukubeka iliso kwi-OSI layer 1.2 iipakethi zempazamo. Uninzi lwamazibuko okubonisa idatha ahluza iipakethi zedatha ezingaqhelekanga, ezingenako ukubonelela ngolwazi oluneenkcukacha noluluncedo lwedatha yokulungisa ingxaki.
4. Ngenxa yokuba i-traffic ye-port ye-mirrored port inyusa umthwalo we-CPU wokutshintsha, kuya kubangela ukuba ukusebenza kokutshintsha kwehle.
Usetyenziso oluqhelekileyo lwe-SPAN
1. Ukudibanisa kunye ne-bandwidth ephantsi kunye nobuchule obuhle bezibuko, i-mirroring ye-multi-port ingasetyenziselwa uhlalutyo oluguquguqukayo kunye nokubeka iliso.
2. Ukubekw'esweni kwendlela: Xa ukubekwa esweni ngokuchanekileyo kungafuneki, kuphela ziinkcukacha-manani zedatha ezingekho mgaqweni ezaneleyo.
3. Iprotocol kunye nohlalutyo lwesicelo: ulwazi olufanelekileyo lwedatha lunokubonelelwa ngokufanelekileyo kunye noqoqosho olusuka kwisibuko sesibuko
4. Ukujongwa kwe-VLAN yonke: Itekhnoloji ye-Mirroring ye-Multi-port ingasetyenziselwa ukubeka esweni ngokulula yonke i-VLAN ekutshintsheni.
Intshayelelo yeVLAN:
Okokuqala, makhe sazise ingcamango esisiseko yesizinda sosasazo. Oku kubhekiselele kuluhlu apho izakhelo zokusasaza (indawo yokufikela iidilesi ze-MAC zizo zonke i-1) zinokusasazwa, kwaye ngamanye amazwi, uluhlu apho unxibelelwano oluthe ngqo lunokwenzeka. Ukuthetha ngokuthe ngqo, ayizizo izakhelo zokusasaza kuphela, kodwa kunye nezakhelo ezininzi kunye nezakhelo ezingaziwayo zeunicast zinokuhamba ngokukhululekileyo ngaphakathi kwendawo yosasazo efanayo.
Ekuqaleni, iLayer 2 switch inokuseka isizinda esinye sosasazo. KuLuhlu lwesi-2 lokutshintsha ngaphandle kweVLANs eqwalaselweyo, nasiphi na isakhelo sosasazo siyakuthunyelwa kuwo onke amazibuko ngaphandle kwezibuko elifumanayo (isikhukula). Nangona kunjalo, ukusebenzisa iiVLAN kuvumela ukuba inethiwekhi yahlulwe ibe yimimandla emininzi yosasazo. Ii-VLAN zibuchwephesha obusetyenziselwa ukwahlula imimandla yosasazo kwi-Layer 2 switch. Ngokusebenzisa iiVLAN, sinokuyila ngokukhululekileyo ukubunjwa kwemimandla yosasazo, sikhulise ukuguquguquka koyilo lwenethiwekhi.
