Yintoni iPacket Slicing yeNetwork Packet Broker (NPB)?
I-Packet Slicing luphawu olunikezelwa ngabathengisi beepakethi zenethiwekhi (ii-NPB) olubandakanya ukubamba nokuthumela ngokukhetha inxalenye yomthwalo wokuqala weepakethi, ukulahla idatha eseleyo. Ivumela ukusetyenziswa kakuhle kwezixhobo zenethiwekhi kunye nokugcina ngokugxila kwiindawo ezibalulekileyo zethrafikhi yenethiwekhi. Luphawu oluxabisekileyo kubathengisi beepakethi zenethiwekhi, oluvumela ukuphathwa kwedatha ngokufanelekileyo nangokujoliswe kuyo, ukuphucula izixhobo zenethiwekhi, kunye nokwenza kube lula ukujonga nokukhusela inethiwekhi ngokufanelekileyo.
Nantsi indlela esebenza ngayo iPacket Slicing kwi-NPB (Network Packet Broker):
1. Ukubanjwa kwePakethi: I-NPB ifumana ithrafikhi yenethiwekhi evela kwimithombo eyahlukeneyo, efana neeswitshi, iitaps, okanye iiports ze-SPAN. Ibamba iipakethi ezidlula kwinethiwekhi.
2. Uhlalutyo lwePakethi: I-NPB ihlalutya iipakethi ezibanjiweyo ukuze imisele ukuba zeziphi iindawo ezifanelekileyo ekubekeni esweni, ekuhlalutyeni, okanye kwiinjongo zokhuseleko. Olu hlalutyo lungasekelwa kwiikhrayitheriya ezifana needilesi ze-IP zomthombo okanye indawo ekuyiwa kuyo, iintlobo zeprotocol, iinombolo zezibuko, okanye umxholo othile womthwalo.
3. Uqwalaselo lweSilayi: Ngokusekelwe kuhlalutyo, i-NPB yenzelwe ukugcina okanye ukulahla iinxalenye zomthwalo wepakethi ngokukhetha. Uqwalaselo luchaza ukuba zeziphi iinxalenye zepakethi ekufuneka zisikwe okanye zigcinwe, njengee-headers, umthwalo wepayethi, okanye amasimi athile eprotocol.
4. Inkqubo yokusika: Ngexesha lenkqubo yokusika, i-NPB iguqula iipakethi ezibanjiweyo ngokwendlela ezicwangcisiweyo ngayo. Inganciphisa okanye isuse idatha yomthwalo ongeyomfuneko ngaphaya kobukhulu obuthile okanye ikhuphe idatha, isuse iintloko ezithile zeprotocol okanye amasimi, okanye igcine kuphela iindawo ezibalulekileyo zomthwalo wepakethi.
5. Ukuthunyelwa Kwepakethi: Emva kwenkqubo yokusika, i-NPB ithumela iipakethi ezilungisiweyo kwiindawo ezimiselweyo, njengezixhobo zokubeka esweni, amaqonga okuhlalutya, okanye izixhobo zokhuseleko. Ezi ndawo zifumana iipakethi ezisikiweyo, eziqulathe kuphela iindawo ezifanelekileyo njengoko kuchaziwe kulungiselelo.
6. Ukubeka iliso kunye noHlalutyo: Izixhobo zokubeka esweni okanye zokuhlalutya eziqhagamshelwe kwi-NPB zifumana iipakethi ezisikiweyo kwaye zenze imisebenzi yazo. Ekubeni idatha engafanelekanga isusiwe, ezi zixhobo zinokugxila kulwazi olubalulekileyo, ziphucule ukusebenza kwazo kwaye zinciphise iimfuno zezixhobo.
Ngokugcina okanye ukulahla iinxalenye zomthwalo wepakethi ngokukhetha, ukunqunyulwa kweepakethi kuvumela ii-NPB ukuba ziphucule izixhobo zenethiwekhi, zinciphise ukusetyenziswa kwe-bandwidth, kwaye ziphucule ukusebenza kwezixhobo zokubeka esweni kunye nohlalutyo. Ivumela ukuphathwa kwedatha okusebenzayo nokujoliswe kuko, iququzelela ukujonga inethiwekhi okusebenzayo kunye nokuphucula imisebenzi yokhuseleko lwenethiwekhi.
Kutheni ke ngoko kufuneka iPacket Slicing yeNetwork Packet Broker (NPB) kwiNetwork Monitoring yakho, Network Analytics kunye noKhuseleko lweNetwork?
Ukusikwa kwePakethikwiNetwork Packet Broker (NPB) iluncedo ekubekeni esweni inethiwekhi kunye neenjongo zokhuseleko lwenethiwekhi ngenxa yezi zizathu zilandelayo:
1. Ithrafikhi yeNethiwekhi Encitshisiweyo: Itrafikhi yenethiwekhi inokuba phezulu kakhulu, kwaye ukubamba nokucubungula zonke iipakethi ngokupheleleyo kunokugqithisa izixhobo zokubeka esweni nokuhlaziya. Ukusikwa kweepakethi kuvumela ii-NPB ukuba zibambe kwaye zithumele kuphela iinxalenye ezifanelekileyo zeepakethi, nto leyo enciphisa umthamo wetrafikhi yenethiwekhi iyonke. Oku kuqinisekisa ukuba izixhobo zokubeka esweni nezokhuseleko zifumana ulwazi oluyimfuneko ngaphandle kokugqithisa izixhobo zazo.
2. Ukusetyenziswa kweZixhobo ngendlela efanelekileyo: Ngokulahla idatha yeepakethi engeyomfuneko, ukunqunyulwa kweepakethi kuphucula ukusetyenziswa kwenethiwekhi kunye nezixhobo zokugcina. Kunciphisa i-bandwidth efunekayo yokudlulisa iipakethi, kunciphisa ukuxinana kwenethiwekhi. Ngaphezu koko, ukunqunyulwa kunciphisa iimfuno zokucubungula kunye nokugcinwa kwezixhobo zokubeka esweni kunye nezokhuseleko, kuphucula ukusebenza kwazo kunye nokukhula kwazo.
3. Uhlalutyo lweDatha oluSebenzayo: Ukusikwa kweepakethi kunceda ukugxila kwidatha ebalulekileyo ngaphakathi komthwalo wepakethi, okwenza ukuba uhlalutyo lube nempumelelo ngakumbi. Ngokugcina ulwazi olubalulekileyo kuphela, izixhobo zokubeka esweni nezokhuseleko zinokucubungula kwaye zihlalutye idatha ngempumelelo ngakumbi, nto leyo ekhokelela ekufumaneni ngokukhawuleza kunye nokuphendula kwiingxaki zenethiwekhi, izoyikiso, okanye imiba yokusebenza.
4. Ubumfihlo obuphuculweyo kunye nokuthobela imithetho: Kwiimeko ezithile, iipakethi zinokuba nolwazi oluyimfihlo okanye oluchonga umntu (PII) olufanele lukhuselwe ngenxa yobumfihlo kunye nezizathu zokuthobela imithetho. Ukusikwa kweepakethi kuvumela ukususwa okanye ukunqunyulwa kwedatha eyimfihlo, kunciphisa umngcipheko wokuvezwa okungagunyaziswanga. Oku kuqinisekisa ukuthotyelwa kwemigaqo yokhuseleko lwedatha ngelixa kuvumela ukuba kubekho ukubekwa esweni kwenethiwekhi kunye nemisebenzi yokhuseleko efunekayo.
5. Ukukhula kunye nokuguquguquka: Ukusikwa kweepakethi kwenza ii-NPB zikwazi ukuphatha iinethiwekhi ezinkulu kunye nokwandisa umthamo wezithuthi ngokufanelekileyo. Ngokunciphisa ubungakanani bedatha edluliselwayo necutshungulwayo, ii-NPB zinokwandisa imisebenzi yazo ngaphandle kokubeka esweni kakhulu kunye neziseko zokhuseleko. Ibonelela ngokuguquguquka kokuziqhelanisa neendawo zenethiwekhi ezitshintshayo kunye nokwamkela iimfuno ezikhulayo ze-bandwidth.
Lilonke, ukunqunyulwa kweepakethi kwi-NPBs kuphucula ukujonga inethiwekhi kunye nokhuseleko lwenethiwekhi ngokuphucula ukusetyenziswa kwezixhobo, ukuvumela uhlalutyo olusebenzayo, ukuqinisekisa ubumfihlo kunye nokuthotyelwa kwemithetho, kunye nokwenza kube lula ukukhulisa. Ivumela imibutho ukuba ijonge kwaye ikhusele iinethiwekhi zayo ngempumelelo ngaphandle kokubeka emngciphekweni ukusebenza okanye ukuphazamisa iziseko zayo zokubeka esweni kunye nokhuseleko.
