Yintoni iPacket Slicing yeNetwork Packet Broker (NPB)?
I-Packet Slicing yinto ebonelelwa ngabaxhasi bepakethe yenethiwekhi (NPBs) ebandakanya ukukhetha ngokukhetha kunye nokudlulisa kuphela inxalenye yomthwalo wepakethi yokuqala, ukulahla idatha eseleyo.Ivumela ukusetyenziswa ngokufanelekileyo kwenethiwekhi kunye nemithombo yokugcina ngokugxila kwiindawo ezibalulekileyo zetrafikhi yenethiwekhi.Luphawu oluxabisekileyo kubathengisi bepakethe yenethiwekhi, evumela ukuphathwa kwedatha okusebenzayo ngakumbi kunye nokujoliswe kuyo, ukuphucula izixhobo zenethiwekhi, kunye nokuququzelela ukubekwa kweliso kwenethiwekhi kunye nokusebenza kokhuseleko.
Nantsi indlela ukusebenza kwePacket Slicing kwiNPB(Network Packet Broker):
1. Packet Capture: I-NPB ifumana itrafikhi yenethiwekhi evela kwimithombo eyahlukeneyo, njengokutshintsha, iitephu, okanye izibuko ze-SPAN.Ibamba iipakethi ezidlula kwinethiwekhi.
2. Uhlalutyo lwePakethi: I-NPB ihlalutya iipakethi ezifakiweyo ukuze ziqinisekise ukuba zeziphi iindawo ezifanelekileyo ekubekweni iliso, ukuhlalutya, okanye iinjongo zokhuseleko.Olu hlalutyo lunokusekelwe kwiikhrayitheriya ezifana nomthombo okanye iidilesi ze-IP, iintlobo zeprotocol, iinombolo ze-port, okanye umxholo othile womvuzo.
3. Uqwalaselo lweSiqwenga: Ngokusekelwe kuhlalutyo, i-NPB ilungiselelwe ukuba igcine ngokukhethiweyo okanye ilahle iinxalenye zomthwalo wepakethe.Ubumbeko luxela ukuba ngawaphi amacandelo epakethi afanele ukusikwa okanye agcinwe, njengeeheader, umvuzo, okanye imihlaba ethile yeprothokholi.
4. Inkqubo yokuSlicing: Ngexesha lenkqubo yokuqhawula, i-NPB iguqula iipakethi ezithathiweyo ngokucwangcisa.Inokunciphisa okanye isuse idatha yomthwalo ongeyomfuneko ngaphaya kobukhulu obuthile okanye i-offset, ihlube iiheader ezithile zeprotocol okanye amasimi, okanye igcine kuphela iindawo ezibalulekileyo zomthwalo wepakethe.
5. Ukuhanjiswa kwePakethi: Emva kwenkqubo yokuqhawula, i-NPB idlulisela phambili iipakethi ezilungisiweyo kwiindawo ezichongiweyo, ezifana nezixhobo zokubeka iliso, iiplatifomu zokuhlalutya, okanye izixhobo zokukhusela.Ezi ndawo zokufikela zifumana iipakethi ezisikiweyo, eziqulethe kuphela izahlulo ezifanelekileyo njengoko kuchaziwe kuqwalaselo.
6. Ukubeka iliso kunye noHlalutyo: Izixhobo zokubeka iliso okanye zokuhlalutya eziqhagamshelwe kwi-NPB zifumana iipakethi ezisikiwe kwaye zenze imisebenzi yazo.Ekubeni idatha engabalulekanga isusiwe, izixhobo zinokugxila kulwazi olubalulekileyo, ukuphucula ukusebenza kwabo kunye nokunciphisa iimfuno zezibonelelo.
Ngokugcina ngokukhetha okanye ukulahla iinxalenye zepakethi yokuhlawula ipakethe, ukunqunyulwa kwepakethe kuvumela i-NPBs ukuba isebenzise izibonelelo zenethiwekhi, ukunciphisa ukusetyenziswa kwe-bandwidth, kunye nokuphucula ukusebenza kwezixhobo zokubeka iliso kunye nokuhlalutya.Ivumela ukuphathwa kwedatha ngokufanelekileyo kunye nokujoliswe kuyo, ukuququzelela ukubeka iliso kwinethiwekhi kunye nokuphucula imisebenzi yokhuseleko lwenethiwekhi.
Ke, kutheni ufuna iPacket Slicing yeNetwork Packet Broker (NPB) yokuJonga iNethiwekhi yakho, uHlalutyi lweNethiwekhi kunye noKhuseleko lweNethiwekhi?
Packet Slicingkwi-Network Packet Broker (NPB) iluncedo kuthungelwano esweni kunye neenjongo zokhuseleko lwenethiwekhi ngenxa yezi zizathu zilandelayo:
1. ITrafikhi yeNethiwekhi eyehlisiwe: I-traffic yenethiwekhi ingaba phezulu kakhulu, kwaye ukubamba kunye nokucubungula zonke iipakethi ngokupheleleyo kunokulayisha ngaphezulu izixhobo zokubeka iliso kunye nokuhlalutya.I-Packet slicing ivumela i-NPBs ukuba ithathe ngokukhethayo kwaye idlulisele kuphela izahlulo ezifanelekileyo zeepakethi, ukunciphisa umthamo wezithuthi zenethiwekhi jikelele.Oku kuqinisekisa ukuba izixhobo zokubeka iliso kunye nokhuseleko zifumana ulwazi oluyimfuneko ngaphandle kokugqithisa izibonelelo zabo.
2. UkuSetyenziswa kweZibonelelo ngokuLungileyo: Ngokulahla idatha yepakethe engadingekile, ukusika ipakethi kukhulisa ukusetyenziswa kwenethiwekhi kunye nezixhobo zokugcina.Inciphisa i-bandwidth efunekayo yokuhambisa iipakethi, ukunciphisa ukuxinana kwenethiwekhi.Ngaphezu koko, ukusika kunciphisa ukusetyenzwa kunye nokugcinwa kweemfuno zokubeka iliso kunye nezixhobo zokhuseleko, ukuphucula ukusebenza kwazo kunye nokulinganisa.
3. Uhlalutyo lwedatha olusebenzayo: Ukusikwa kwepakethi kunceda ukugxila kwidatha ebalulekileyo ngaphakathi kwepakethi yokuhlawula ipakethe, okwenza uhlalutyo olusebenzayo.Ngokugcina ulwazi oluyimfuneko kuphela, izixhobo zokubeka iliso kunye nokhuseleko zinokuqhuba kwaye zihlalutye idatha ngokufanelekileyo, okukhokelela ekubhaqweni ngokukhawuleza kunye nokuphendula kwi-anomalies yenethiwekhi, izoyikiso, okanye imiba yokusebenza.
4. Ubungasese obuphuculweyo kunye nokuThobela: Kwiimeko ezithile, iipakethi zisenokuqulatha ulwazi olunovakalelo okanye olunokuchonga umntu (PII) ekufuneka lukhuselwe ngenxa yabucala kunye nezizathu zokuthotyelwa.Ukunqunyulwa kwepakethi kuvumela ukususwa okanye ukunqunyulwa kwedatha ebuthathaka, ukunciphisa umngcipheko wokuvezwa okungagunyaziswanga.Oku kuqinisekisa ukuthotyelwa kwemigaqo yokhuseleko lwedatha ngelixa kusenza kube lula ukubeka iliso kwinethiwekhi kunye nokusebenza kokhuseleko.
5. I-Scalability kunye nokuguquguquka: Ukunqunyulwa kwepakethi kwenza ii-NPB zikwazi ukuphatha amanethiwekhi amakhulu kunye nokwandisa umthamo wezithuthi ngokufanelekileyo.Ngokunciphisa inani ledatha ehanjiswayo kunye nokucutshungulwa, ii-NPB zinokunyusa imisebenzi yazo ngaphandle kokubeka iliso kakhulu kunye neziseko zokhuseleko.Ibonelela ngokuguquguquka ukuqhelana neemeko zenethiwekhi eziguqukayo kwaye ivumelane neemfuno ezikhulayo ze-bandwidth.
Ngokubanzi, ukucandwa kwepakethi kwii-NPBs kuphucula ukubeka iliso kuthungelwano kunye nokhuseleko lwenethiwekhi ngokulungiselela ukusetyenziswa kobutyebi, ukwenza uhlalutyo olusebenzayo, ukuqinisekisa ubumfihlo kunye nokuthotyelwa, kunye nokuququzelela ukulinganisa.Ivumela imibutho ukuba ibeke iliso ngokufanelekileyo kwaye ikhusele uthungelwano lwabo ngaphandle kokubeka esichengeni ukusebenza okanye ukugqithisela ukubeka iliso kunye neziseko zokhuseleko.
