Kuyini Ukusikwa Kwephakethe Lomthengisi Wepakethe Yenethiwekhi (NPB)?
I-Packet Slicing iyisici esinikezwa ngabathengisi bepakethe benethiwekhi (ama-NPB) esihilela ukubamba nokudlulisa ngokukhetha ingxenye yomthwalo wepakethe wokuqala, ukulahla idatha esele. Ivumela ukusetshenziswa kahle kwezinsiza zenethiwekhi nesitoreji ngokugxila ezingxenyeni ezibalulekile zethrafikhi yenethiwekhi. Kuyisici esibalulekile kubathengisi bepakethe benethiwekhi, okuvumela ukuphathwa kwedatha okusebenzayo nokuqondiswe kakhudlwana, ukwenza ngcono izinsiza zenethiwekhi, kanye nokwenza lula ukuqapha kwenethiwekhi nokusebenza kokuphepha okuphumelelayo.
Nansi indlela i-Packet Slicing esebenza ngayo ku-NPB (Network Packet Broker):
1. Ukuthwebula Iphakethe: I-NPB ithola ithrafikhi yenethiwekhi evela emithonjeni ehlukahlukene, njengezishintshi, ama-tap, noma ama-port e-SPAN. Ibamba amaphakethe adlula kunethiwekhi.
2. Ukuhlaziywa Kwephakethe: I-NPB ihlaziya amaphakethe athwetshuliwe ukuze inqume ukuthi yiziphi izingxenye ezifanele ukuqapha, ukuhlaziya, noma izinjongo zokuphepha. Lokhu kuhlaziya kungasekelwa ezindinganisweni ezifana namakheli e-IP omthombo noma indawo oya kuyo, izinhlobo zephrothokholi, izinombolo zechweba, noma okuqukethwe okuthile komthwalo.
3. Ukucushwa Kwesilayi: Ngokusekelwe ekuhlaziyweni, i-NPB ilungiselelwe ukugcina noma ukulahla izingxenye zomthwalo wephakethe ngokukhetha. Ukucushwa kucacisa ukuthi yiziphi izingxenye zephakethe okufanele zisikwe noma zigcinwe, njengezinhloko, umthwalo wenkokhelo, noma izinkambu ezithile zephrothokholi.
4. Inqubo Yokusika: Ngesikhathi senqubo yokusika, i-NPB iguqula amaphakethe athwetshuliwe ngokuya ngokucushwa. Inganciphisa noma isuse idatha yomthwalo ongadingekile ngale kosayizi othile noma isuse, isuse izihloko noma amasimu athile ephrothokholi, noma igcine izingxenye ezibalulekile zomthwalo womthwalo wephakethe kuphela.
5. Ukudluliselwa Kwephakethe: Ngemva kwenqubo yokusika, i-NPB idlulisela amaphakethe aguquliwe ezindaweni ezikhethiwe, njengamathuluzi okuqapha, amapulatifomu okuhlaziya, noma izinto zokuphepha. Lezi zindawo zithola amaphakethe aqoshiwe, aqukethe izingxenye ezifanele kuphela njengoba kuchaziwe ekucushweni.
6. Ukuqapha Nokuhlaziya: Amathuluzi okuqapha noma okuhlaziya axhunywe ku-NPB athola amaphakethe asikiwe futhi enze imisebenzi yawo. Njengoba idatha engabalulekile isusiwe, amathuluzi angagxila olwazini olubalulekile, athuthukise ukusebenza kwawo kahle futhi anciphise izidingo zezinsizakusebenza.
Ngokugcina noma ukulahla izingxenye zomthwalo wephakethe ngokukhetha, ukunqunywa kwephakethe kuvumela ama-NPB ukuthi athuthukise izinsiza zenethiwekhi, anciphise ukusetshenziswa kwe-bandwidth, futhi athuthukise ukusebenza kwamathuluzi okuqapha nokuhlaziya. Kwenza kube lula ukuphatha idatha ngendlela ephumelelayo neqondile, kusiza ukuqapha inethiwekhi ngempumelelo kanye nokuthuthukisa imisebenzi yokuphepha kwenethiwekhi.
Pho-ke, kungani udinga i-Packet Slicing of Network Packet Broker (NPB) yokuqapha inethiwekhi yakho, i-Network Analytics kanye nokuphepha kwenethiwekhi?
Ukusikwa KwephaketheKu-Network Packet Broker (NPB) kuyasiza ekuqapheni inethiwekhi kanye nezinjongo zokuphepha kwenethiwekhi ngenxa yezizathu ezilandelayo:
1. Ithrafikhi Yenethiwekhi Encishisiwe: Ithrafikhi yenethiwekhi ingaba phezulu kakhulu, futhi ukubamba nokucubungula wonke amaphakethe ngokuphelele kungalayisha kakhulu amathuluzi okuqapha nokuhlaziya. Ukusikwa kwamaphakethe kuvumela ama-NPB ukuthi abambe futhi adlulisele ngokukhetha izingxenye ezifanele zamaphakethe kuphela, okunciphisa ivolumu yethrafikhi yenethiwekhi iyonke. Lokhu kuqinisekisa ukuthi amathuluzi okuqapha nokuphepha athola ulwazi oludingekayo ngaphandle kokucindezela izinsiza zawo.
2. Ukusetshenziswa Kwezinsiza Okuhle Kakhulu: Ngokulahla idatha yephakethe engadingekile, ukunqunywa kwephakethe kuthuthukisa ukusetshenziswa kwenethiwekhi kanye nezinsiza zokugcina. Kunciphisa i-bandwidth edingekayo yokudlulisa amaphakethe, kunciphisa ukuminyana kwenethiwekhi. Ngaphezu kwalokho, ukunqunywa kunciphisa izidingo zokucubungula kanye nokugcina amathuluzi okuqapha kanye nokuphepha, kuthuthukisa ukusebenza kwawo kanye nokukhula kwawo.
3. Ukuhlaziywa Kwedatha Okusebenzayo: Ukusikwa kwephakethe kusiza ukugxila kudatha ebalulekile ngaphakathi komthwalo wephakethe, okwenza kube lula ukuhlaziya okusebenzayo. Ngokugcina ulwazi olubalulekile kuphela, amathuluzi okuqapha kanye nokuphepha angacubungula futhi ahlaziye idatha ngempumelelo, okuholela ekutholakaleni okusheshayo kanye nokuphendula ezinkingeni zenethiwekhi, izinsongo, noma izinkinga zokusebenza.
4. Ubumfihlo Obuthuthukisiwe Nokuthobela Imithetho: Ezimweni ezithile, amaphakethe angase aqukathe ulwazi olubucayi noma oluhlonza umuntu (PII) okufanele luvikelwe ngezizathu zobumfihlo kanye nokuthobela imithetho. Ukusikwa kwamaphakethe kuvumela ukususwa noma ukunqunywa kwedatha ebucayi, kunciphisa ingozi yokudalulwa okungagunyaziwe. Lokhu kuqinisekisa ukuhambisana nemithethonqubo yokuvikela idatha ngenkathi kusavumela ukuqapha kwenethiwekhi kanye nokusebenza kokuphepha okudingekayo.
5. Ukukhula Nokuguquguquka: Ukusikwa kwamaphakethe kwenza ama-NPB akwazi ukuphatha amanethiwekhi amakhulu nokwandisa inani lethrafikhi ngendlela ephumelelayo. Ngokunciphisa inani ledatha edluliselwayo necutshungulwayo, ama-NPB angakhulisa imisebenzi yawo ngaphandle kokucindezela ingqalasizinda yokuqapha kanye nokuphepha. Kunikeza ukuguquguquka kokuzivumelanisa nezimo zenethiwekhi ezishintshashintshayo nokwamukela izidingo ze-bandwidth ezikhulayo.
Sekukonke, ukunqunywa kwamaphakethe kuma-NPB kuthuthukisa ukuqapha kwenethiwekhi kanye nokuphepha kwenethiwekhi ngokwenza ngcono ukusetshenziswa kwezinsizakusebenza, kuvumela ukuhlaziywa okusebenzayo, ukuqinisekisa ubumfihlo kanye nokuthobela imithetho, kanye nokwenza kube lula ukukhulisa. Kuvumela izinhlangano ukuthi ziqaphe futhi zivikele amanethiwekhi azo ngempumelelo ngaphandle kokubeka engcupheni ukusebenza noma ukucindezela ingqalasizinda yazo yokuqapha kanye nokuphepha.
