Xa isixhobo sokuchongwa kwezinto (i-IDS) sithunyelwe, izibuko ezivelelayo kwiZiko loLwazi lweqela loontanga akwanelanga (umzekelo, isibuko esinye sivumelekile kwezinye izixhobo).
Ngeli xesha, xa singasongezi amazibuko amaninzi, singasebenzisa ukuphindaphinda kwenethiwekhi, ukudityaniswa kunye nokudlulisela isixhobo sokuhambisa inani elifanayo ledatha kwisixhobo sedatha.
Ithini i-Network yenethiwekhi?
Mhlawumbi uqala ukuva i-Tap Switch. Thepha (indawo yokufikelela kwisiphelo), ekwabizwa ngokuba yi-NPB (i-packet yenethiwekhi), okanye icofe i-Agggaredator?
Umsebenzi ophambili wempompo kukuseta phakathi kwezibuko ezivelelayo kwinethiwekhi yemveliso kunye neqela lezixhobo zohlalutyo. Impompo iqokelela itrafikhi ebonisiweyo okanye eyahluliweyo kwisixhobo esinye okanye ngaphezulu semveliso yenethiwekhi kwaye ihambisa itrafikhi kwisixhobo esinye okanye ezingaphezulu.
Inethiwekhi yeNethiwekhi yeNethiwekhi yeNethiwekhi yeNethiwekhi
I-Network ineelebheli ezibonakalayo, ezinje:
Izixhobo ezizimeleyo
Thepha sisiqwenga esahlukileyo esingachaphazeli umthwalo kwizixhobo zenethiwekhi esele ikho, esona sibonelelo sezibuko.
Tshintsha?
I-Network yenethiwekhi?
Inethiwekhi ibonakale
Emva kokuba impompo iqhagamshelwe kwinethiwekhi, zonke ezinye izixhobo kwinethiwekhi azichaphazelekanga. Kubo, impompo ibonakala ngokucacileyo njengomoya, kwaye izixhobo zokubeka iliso zixhunyiwe kwimpompo zibonakale kwinethiwekhi xa iyonke.
I-TAP ifana nje ne-port ebonisa isipili kwi-switch. Ke kutheni hlula itephu eyahlukileyo? Makhe sijonge ezinye umahluko phakathi kwenethiwekhi kunye ne-port yenethiwekhi eguqulelekileyo.
Umahluko 1: Impompo yenethiwekhi kulula ukuyicwangcisa kunezibuko
Izibuko le-port kufuneka zilungiselelwe kwi-switch. Ukuba ukubeka iliso kufuneka kulungiswe, i-switch kufuneka iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde ihlawulwe. Nangona kunjalo, impompo kufuneka ihlengahlengiswe apho iceliwe, engenampembelelo kwizixhobo zenethiwekhi ekhoyo.
Umahluko 2: Impompo yenethiwekhi ayichaphazeli ukusebenza kwenethiwekhi kwi-por port
Isibuko esiguqulelayo kwi-switch esonakele ukwenza intsebenzo yokutshintsha kwaye kuchaphazele amandla okutshintsha. Ngokukodwa, ukuba utshintsho luqhagamshelwe kwinethiwekhi malunga nothotho lwe-inline, ukudlulisela phambili kwenethiwekhi yonke ichaphazelekile. Thepha yi-handore elizimeleyo kwaye ayichaphazeli ukusebenza kwesixhobo ngenxa yokuguqulelwa kwezithuthi. Ke ngoko, ayinampembelelo kumthwalo wezixhobo zenethiwekhi ekhoyo, ezineenzuzo ezinkulu ngaphezulu kwe-port.
Umahluko 3: Impompo yenethiwekhi ibonelela ngenkqubo epheleleyo yezithuthi kune-port yokuguqula iphindaphinde
Izibuko eziguqulelayo azinakuqinisekisa ukuba zonke izithuthi zinokufunyanwa ngenxa yokuba izibuko lokutshintsha liya kucoca iipakethi zemposiso okanye iipakethi ezincinci. Nangona kunjalo, i-tag iqinisekisa ingqibelelo kuba yi "probliction" epheleleyo "kwi-famier yomzimba.
Umahluko 4: Ukulibaziseka kokudlulisela impompo kuncinci kuneso sezibuko
Kwimisitho yokuphela kwesiphelo, isibuko sePort sinokuzisa i-LENCE XA KUKHONA IXESHA LOKUQHUTYELWA KWEENKONZO ZESIFUNDO, KAKHULU KWI-PORS ye-10 / 100m kwi-Giga Ethernet.
Nangona oku kubhalwa ngokubanzi, siyakholelwa ukuba oluhlalutyo lwamaxesha amabini alunamsebenzi omeleleyo kubuchwephesha.
Ke, yeyiphi imeko ngokubanzi, kufuneka sisebenzise impompo yokuhanjiswa kwendlela? Ngokulula, ukuba unazo ezi mfuno zilandelayo, emva koko i-Netlet icop yeyokhetho lwakho olululo.
Itekhnoloji ye-Tep yenethiwekhi
Mamela ezi zinto zingasentla, zive inethiwekhi ye-shist ye-shint sisixhobo somlingo, impompo yangoku impompo isebenzisa indawo yoyilo ephantsi kwezigaba ezintathu:
Fpga
- Ukwenza okuphezulu
-Nzima ukuphuhlisa
-Iindleko eziphezulu
Iingcebiso
-Sebenzisa kwaye ilula
-Unobunzima bokuphuhlisa
- Abathengisi abaphambili beRMI noCavium bayeka uphuhliso kwaye basilela kamva
I-anic
- Ukwenza okuphezulu
-Ukuphuhliswa komsebenzi wokwanda kunzima, ikakhulu ngenxa yokusikelwa komda we-chip quip ngokwayo
-Umuquzeleli kunye neenkcazo zinqunyelwe yi-chip ngokwayo, zikhokelela ekusebenzeni kakubi
Ke ngoko, uxinzelelo oluphezulu kunye nesantya senethiwekhi esiphezulu esibonakalayo kwimarike sinegumbi elininzi lokuphucula ukuguquguquka kokusetyenziswa. Thepha ii-hitters zenethiwekhi zisetyenziselwa ukuguqulwa kweProtocol, ukuqokelelwa kwedatha, ukuqhutywa kwedatha, ukuluguqula kwedatha, kunye nokucoca itrafiki. Iintlobo zePort eziPhezulu ziquka i-100g, i-40g, i-10g, i-2.5g, njl njl. Njl.
