Iyini i-Packet Slicing ye-Network Packet Broker(NPB)?
I-Packet Slicing isici esihlinzekwe abathengisi bephakethe lenethiwekhi (NPBs) esihilela ukukhetha nokudlulisa kuphela ingxenye yomthwalo wephakethe loqobo, ukulahla idatha esele. Ivumela ukusetshenziswa ngokuphumelelayo kwezinsiza zenethiwekhi nesitoreji ngokugxila ezingxenyeni ezibalulekile zethrafikhi yenethiwekhi. Kuyisici esibalulekile kubadayisi bephakethe benethiwekhi, evumela ukuphathwa kwedatha okusebenza kahle kakhulu nokuqondisiwe, ukuthuthukisa izinsiza zenethiwekhi, nokwenza lula ukuqapha kwenethiwekhi nokusebenza okuphephile.
Nansi indlela I-Packet Slicing esebenza ngayo ku-NPB(Network Packet Broker):
1. Iphakethe Capture: I-NPB ithola ithrafikhi yenethiwekhi evela emithonjeni ehlukahlukene, efana nokushintsha, ompompi, noma izimbobo ze-SPAN. Ithwebula amaphakethe adlula kunethiwekhi.
2. Ukuhlaziywa Kwephakethe: I-NPB ihlaziya amaphakethe athathiwe ukuze inqume ukuthi yiziphi izingxenye ezifanelekile ekuqaphelweni, ekuhlaziyeni, noma ezinjongo zokuphepha. Lokhu kuhlaziya kungase kusekelwe kumibandela efana namakheli e-IP omthombo noma endawo, izinhlobo zephrothokholi, izinombolo zembobo, noma okuqukethwe okuthile okukhokhelwayo.
3. Ukucushwa Kwesiqephu: Ngokusekelwe ekuhlaziyweni, i-NPB ilungiselelwe ukuthi igcine ngokukhetha noma ilahle izingxenye zokulayisha kwephakethe. Ukulungiselelwa kucacisa ukuthi yiziphi izigaba zephakethe okufanele zisikwe noma zigcinwe, njengezihloko, umthwalo okhokhelwayo, noma izinkambu zephrothokholi ethile.
4. Inqubo yokusika: Phakathi nenqubo yokusika, i-NPB iguqula amaphakethe athunjiwe ngokuvumelana nokucushwa. Inganciphisa noma isuse idatha yokulayisha okungadingekile ngaphezu kosayizi othize noma i-offset, ihlubule izihloko zephrothokholi ethile noma izinkambu, noma igcine izingxenye ezibalulekile kuphela zomthwalo okhokhelwayo wephakethe.
5. Ukudlulisa Iphakethe: Ngemva kwenqubo yokusika, i-NPB idlulisela amaphakethe ashintshiwe ezindaweni ezikhethiwe, njengamathuluzi okuqapha, izinkundla zokuhlaziya, noma izinto zikagesi zokuphepha. Lezi zindawo zithola amaphakethe asikiwe, aqukethe kuphela izingxenye ezifanele njengoba kucaciswe ekucushweni.
6. Ukuqapha Nokuhlaziya: Amathuluzi okuqapha noma okuhlaziya axhunywe ku-NPB athola amaphakethe asikiwe futhi enze imisebenzi yawo ngokulandelana kwawo. Njengoba idatha engabalulekile isusiwe, amathuluzi angagxila olwazini olubalulekile, athuthukise ukusebenza kahle kwawo futhi ehlise izidingo zensiza.
Ngokugcina ngokukhetha noma ukulahla izingxenye zokukhokhelwa kwephakethe, ukusika iphakethe kuvumela ama-NPB ukuthi athuthukise izinsiza zenethiwekhi, anciphise ukusetshenziswa komkhawulokudonsa, futhi athuthukise ukusebenza kwamathuluzi okuqapha nokuhlaziya. Inika amandla ukuphathwa kwedatha okusebenza kahle kakhulu nokuhlosiwe, kusiza ukuqapha kwenethiwekhi okuphumelelayo kanye nokuthuthukisa imisebenzi yokuphepha kwenethiwekhi.
Manje-ke, kungani udinga i-Packet Slicing of Network Packet Broker(NPB) yokuqapha Inethiwekhi yakho, i-Network Analytics kanye Nokuphepha Kwenethiwekhi?
Ukusika iphaketheku-Network Packet Broker (NPB) inenzuzo yokuqapha inethiwekhi nezinjongo zokuphepha zenethiwekhi ngenxa yezizathu ezilandelayo:
1. I-Traffic Yenethiwekhi Eyehlisiwe: Ithrafikhi yenethiwekhi ingaba phezulu kakhulu, futhi ukuthwebula nokucubungula wonke amaphakethe ewonke kungalayisha kakhulu amathuluzi okuqapha nawokuhlaziya. Ukusikwa kwephakethe kuvumela ama-NPB ukuthi athwebule ngokukhetha futhi adlulisele izingxenye ezifanele zamaphakethe kuphela, kunciphisa ivolumu yethrafikhi yenethiwekhi iyonke. Lokhu kuqinisekisa ukuthi amathuluzi okuqapha nawokuvikela athola ulwazi oludingekayo ngaphandle kokugcwala izinsiza zawo.
2. Ukusetshenziswa Kwensiza Okulungile: Ngokulahla idatha yephakethe engadingekile, ukusika iphakethe kuthuthukisa ukusetshenziswa kwenethiwekhi nezinsiza zokulondoloza. Inciphisa umkhawulokudonsa odingekayo ekuthumeleni amaphakethe, inciphisa ukuminyana kwenethiwekhi. Ngaphezu kwalokho, ukusika kunciphisa izidingo zokucubungula nokugcinwa kwamathuluzi okuqapha nokuphepha, ukuthuthukisa ukusebenza kwawo kanye nokulinganisa.
3. Ukuhlaziywa Kwedatha Okuphumelelayo: Ukusikwa kwephakethe kusiza ukugxila kudatha ebalulekile ngaphakathi kokukhokhelwa kwephakethe, okuvumela ukuhlaziya okusebenza kahle kakhudlwana. Ngokugcina ulwazi olubalulekile kuphela, amathuluzi okuqapha nawokuvikela angacubungula futhi ahlaziye idatha ngempumelelo kakhudlwana, okuholela ekutholakaleni okusheshayo nokusabela kokudidayo kwenethiwekhi, izinsongo, noma izinkinga zokusebenza.
4. Ubumfihlo Nokuthobelana Okuthuthukisiwe: Kwezinye izimo, amaphakethe angaqukatha ulwazi olubucayi noma oluhlonza umuntu siqu (i-PII) okufanele luvikelwe ngenxa yezizathu zobumfihlo nokuhambisana. Ukusika iphakethe kuvumela ukususwa noma ukuncishiswa kwedatha ebucayi, kunciphisa ubungozi bokuchayeka okungagunyaziwe. Lokhu kuqinisekisa ukuthotshelwa kwemithetho yokuvikela idatha kuyilapho kusavumela ukuqapha kwenethiwekhi nokusebenza kokuphepha okudingekayo.
5. I-Scalability kanye Nokuvumelana nezimo: Ukusikwa kwephakethe kwenza ama-NPB akwazi ukuphatha amanethiwekhi amakhulu futhi akhuphule amanani ethrafikhi ngempumelelo. Ngokunciphisa inani ledatha edluliswayo necutshungulwayo, ama-NPB angakwazi ukukala imisebenzi yawo ngaphandle kwengqalasizinda yokuqapha nokuvikeleka okukhulu. Inikeza ukuguquguquka kokuzivumelanisa nezimo zenethiwekhi eziguqukayo futhi yamukele izidingo ezikhulayo zomkhawulokudonsa.
Sekukonke, ukusikwa kwephakethe kuma-NPB kuthuthukisa ukuqapha kwenethiwekhi nokuphepha kwenethiwekhi ngokuthuthukisa ukusetshenziswa kwensiza, ukunika amandla ukuhlaziya okuphumelelayo, ukuqinisekisa ubumfihlo nokuhambisana, kanye nokwenza lula ukukala. Ivumela izinhlangano ukuthi ziqaphe ngempumelelo futhi zivikele amanethiwekhi azo ngaphandle kokuphazamisa ukusebenza noma ukweqa ingqalasizinda yazo yokuqapha nokuvikeleka.
