Ngiyaqiniseka ukuthi uyawazi umshikashika phakathi kwe-Network Tap(Iphoyinti Lokufinyelela Lokuhlola) kanye nesihlaziyi sembobo yokushintsha (imbobo ye-SPAN) ngezinjongo zokuqapha Inethiwekhi. Kokubili kunamandla okubonisa ithrafikhi kunethiwekhi futhi kuyithumele kumathuluzi okuphepha angaphandle kwebhendi njengamasistimu okuthola ukungena, abalogi benethiwekhi, noma abahlaziyi benethiwekhi. Izimbobo ze-span zilungiswa kumaswishi ebhizinisi lenethiwekhi anomsebenzi wokwenza isibuko sembobo. Kuyimbobo enikelwe ekushintsheni ephethwe ethatha ikhophi yesibuko sethrafikhi yenethiwekhi ukusuka ekushintsheni ukuyithumela kumathuluzi okuvikela. I-TAP, ngakolunye uhlangothi, iyisisetshenziswa esabalalisa kancane ithrafikhi yenethiwekhi isuka kunethiwekhi iye ethuluzini lokuvikela. I-TAP ithola ithrafikhi yenethiwekhi kuzo zombili izinkomba ngesikhathi sangempela kanye nesiteshi esihlukile.
Lezi yizinzuzo ezinhlanu eziyinhloko ze-TAP ngembobo ye-SPAN:
1. I-TAP ithwebula iphakethe ngalinye!
I-Span Isusa amaphakethe namaphakethe awonakele amancane kunosayizi omncane. Ngakho-ke, amathuluzi okuphepha awakwazi ukwamukela yonke ithrafikhi ngoba izimbobo ze-span zinikeza okubaluleke kakhulu ithrafikhi yenethiwekhi. Ngaphezu kwalokho, ithrafikhi ye-RX ne-TX ihlanganiswe echwebeni elilodwa, ngakho-ke amaphakethe maningi amathuba okuthi awiswe. I-TAP ithwebula yonke ithrafikhi yezindlela ezimbili endaweni ngayinye eqondiwe, okuhlanganisa namaphutha embobo.
2. Isixazululo se-passive ngokuphelele, akukho ukucushwa kwe-IP noma ukunikezwa kwamandla okudingekayo
I-Passive TAP isetshenziswa ngokuyinhloko kumanethiwekhi e-fiber optic. Ku-TAP yokwenziwa, ithola ithrafikhi kuzo zombili izinkomba zenethiwekhi futhi ihlukanise ukukhanya okungenayo ukuze u-100% wethrafikhi ubonakale ethuluzini lokuqapha. I-Passive TAP ayidingi ukunikezwa kwamandla. Ngenxa yalokho, bangeza ungqimba lokuphinda baphelelwe umsebenzi, badinga ukulungiswa okuncane, futhi banciphise izindleko zizonke. Uma uhlela ukuqapha ithrafikhi ye-Ethernet yethusi, udinga ukusebenzisa i-TAP esebenzayo. I-Active TAP idinga ugesi, kodwa i-Active TAP ye-Niagra ihlanganisa ubuchwepheshe be-bypass obungaphephile obususa ingcuphe yokuphazamiseka kwesevisi uma kwenzeka ugesi ucisha.
3. Ukulahlekelwa kwephakethe le-Zero
I-Network TAP iqapha zombili iziphetho zesixhumanisi ukuze inikeze ukubonakala okungu-100% kwethrafikhi yenethiwekhi yezindlela ezimbili. I-TAP ayiwalahli noma yimaphi amaphakethe, kungakhathaliseki ukuthi i-bandwidth yawo.
4. Ifanele ukusetshenziswa kwenethiwekhi okuphakathi nendawo ukuya phezulu
Imbobo ye-SPAN ayikwazi ukucubungula izixhumanisi zenethiwekhi ezisetshenziswa kakhulu ngaphandle kokulahla amaphakethe. Ngakho-ke, i-TAP yenethiwekhi iyadingeka kulezi zimo. Uma kugeleza ithrafikhi eningi ephuma ku-SPAN kunaleyo etholwayo, imbobo ye-SPAN iba ngokubhaliswa ngokweqile futhi iphoqeleka ukuthi ilahle amaphakethe. Ukuze uthwebule i-10Gb yethrafikhi yezindlela ezimbili, imbobo ye-SPAN idinga u-20Gb womthamo, futhi i-10Gb Network TAP izokwazi ukuthwebula yonke i-10Gb yomthamo.
5. I-TAP Ivumela yonke i-traffic ukuthi idlule, kuhlanganise namathegi e-VLAN
Izimbobo ze-Span ngokuvamile azivumeli amalebula e-VLAN ukuthi adlule, okwenza kube nzima ukuthola izinkinga ze-VLAN nokudala izinkinga mbumbulu. I-TAP igwema izinkinga ezinjalo ngokuvumela yonke ithrafikhi ukuthi idlule.
