TusNetwork Packet Broker(NPB), uas suav nrog cov neeg siv 1g feem ntau, 10g NPB, 25G NPB, 40g NPB, 100g NPB, 400G NPB, thiabNetwork qhov chaw nkag mus kuaj (Kais), yog cov khoom siv kho vajtse uas ntsaws ncaj qha rau hauv lub network cable thiab xa ib daig ntawm kev sib txuas lus hauv kev sib txuas lus rau lwm cov khoom siv.
Network pob ntawv broket cov brokers muaj feem ntau siv hauv kev tsim kho network intution tshuab (ID), cov neeg kuaj tes haujlwm network, thiab cov profilers. Chaw nres nkoj mecking kev sib ntsib. Nyob rau hauv hom shunting, tus saib xyuas utp txuas (unmasked txuas (unmasked txuas) tau muab faib ua ob ntu los ntawm cov kais dej. Cov ntaub ntawv shunted tau txuas nrog kev sib sau sib txuas los sau cov ntaub ntawv rau Internet cov ntaub ntawv kev saib xyuas cov ntaub ntawv.
Network cov pob ntawv pob khoom lag luam (NPB) ua rau koj?
Cov Nta Tseem Ceeb:
1. Muaj kev ywj pheej
Nws yog ib qho kev ywj pheej ntawm cov kho vajtse thiab tsis cuam tshuam rau cov khoom siv ntawm cov khoom siv network uas twb muaj lawm, uas muaj txiaj ntsig zoo dua chaw nres nkoj moring.
Nws yog ib qho khoom siv hauv-kab, uas tsuas txhais tau tias nws yuav tsum tau xaim rau hauv lub network. Txawm li cas los xij, qhov no kuj muaj qhov tsis zoo ntawm kev qhia txog qhov tsis ua tiav, thiab vim tias nws yog lub sijhawm online yuav tsum tau cuam tshuam rau lub sijhawm xa tawm, nyob ntawm seb qhov twg nws tau siv.
2. Pob tshab
Pob tshab txhais tau tias tus taw tes rau lub network tam sim no. Tom qab nkag mus rau lub network shunt, nws tsis muaj kev cuam tshuam rau txhua cov khoom siv hauv cov network tam sim no, thiab yog pob tshab rau lawv. Ntawm chav kawm, qhov no tseem suav nrog cov tsheb xa los ntawm lub network shunt rau cov ntaus ntawv saib xyuas, uas yog cov pob tshab mus rau lub network.
Ua haujlwm ua haujlwm:
Cov kev khiav dej (faib tawm) raws li cov ntaub ntawv nkag, sib sau ua ke kom paub meej txog kev hloov pauv ntawm tib lub sijhawm, lossis cov khoom siv IP tib yam li cov neeg siv sib cuam tshuam.
Muaj nuj nqi nta:
1. Kev hloov pauv kev hloov pauv
Cov ntaub ntawv hauv Internet tseem ceeb siv los ntawm ISPS suav nrog cov ntaub ntawv uas tau siv los ntawm cov ntaub ntawv thov cov ntaub ntawv yog ge thiab 10ge interfaces. Yog li ntawd, cov txheej txheem hloov dua siab tshiab feem ntau tau hais txog kev sib txuas hauv Is Taws Nem tsuas yog hais txog hloov dua siab tshiab ntawm 40ge Wan thiab 10ge lan thiab ge.
2. Cov ntaub ntawv sau thiab xa tawm.
Feem ntau cov ntaub ntawv sau cov ntaub ntawv yuav tsum rho tawm cov tsheb uas lawv tau saib xyuas thiab muab pov tseg cov tsheb uas lawv tsis quav ntsej txog. Cov ntaub ntawv tsheb ntawm cov chaw nyob IP tshwj xeeb, raws tu qauv, thiab chaw nres nkoj tus IP, chaw nres nkoj, thiab cov qauv ua haujlwm, thiab kev sib koom ua ke) kev sib hloov. Thaum tso zis, tib qhov chaw, tib qho chaw thiab thauj khoom sib npaug tawm tau zoo raws li Hashorithm tshwj xeeb.
3. Cov lej lim
Rau p2p kev sib sau ua ke, daim ntawv thov yuav tsuas yog tsom rau qee cov tsheb sib txawv, thiab cov ntsiab lus streaming, thiab lwm yam. Lub diverter txhawb nqa cov lej ua haujlwm feature feature code lim thiab ntab feation code lim. Lub khob ntab feating feater code yog kev pabcuam tshwj xeeb rau ntawm lub hauv paus ntawm qhov chaw nyob ruaj khov. Nws yog qhov tsim nyog rau cov ntawv thov uas qhia meej qhov kev cai tshwj xeeb kom tau lim, tab sis tsis qhia meej qhov chaw ntawm lub cim tshwj xeeb.
4. Kev Sib Tham
Qhia txog kev sib ntsib tsheb thiab hloov tau teeb tsa kev sib kho rau kev sib kho N tus nqi (n = 1 txog 1024). Ntawd yog, thawj n pob ntawv ntawm txhua ntu yog rho tawm thiab xa mus rau qhov chaw thov rov qab, thiab pob ntawv tom qab, txuag tau cov nyiaj siv nyiaj siv rau cov dej hauv qis. Feem ntau, thaum koj siv tus lej ID los saib xyuas cov xwm txheej, koj tsis tas yuav txheej txheem txhua lub pob ntawv ntawm tag nrho cov kev sib ntsib; Hloov chaw, koj tsuas yog yuav tsum tau rho tawm thawj N pob ntawv ntawm txhua ntu kom tiav cov kev txheeb xyuas thiab tshuaj xyuas.
5. Cov ntaub ntawv tsom iav thiab replication
Lub splitter tuaj yeem paub cov tsom iav thiab rov ua dua ntawm cov ntaub ntawv ntawm cov zis interface, uas ua kom cov ntaub ntawv nkag tau ntawm cov ntawv thov cov ntawv thov.
6. 3G Network cov ntaub ntawv tau txais thiab xa mus
Cov ntaub ntawv sau thiab faib tawm ntawm 3G tes hauj lwm sib txawv ntawm cov qauv tsom xam network. Pob ntawv ntawm 3G cov tes hauj lwm tau kis ntawm kab nraub qaum los ntawm ntau txheej ntawm encapsulation. Pob ntawv ntev thiab encapsulation hom yog txawv ntawm cov pob ntawv ntawm cov network sib txuas. Lub splitter tuaj yeem txheeb xyuas qhov tseeb thiab cov txheej txheem ua kom nruj xws li GTP thiab GE pob ntawv, thiab VLAN pob ntawv. Nws tuaj yeem rho tawm iups signaling pob ntawv, GTP cov paib kos npe rau cov pob kws ua haujlwm raws li cov pob khoom raws li cov pob ntawv. Ib qho ntxiv, nws tuaj yeem faib cov pob ntawv raws li tus IP chaw nyob sab hauv. Kev them nyiaj yug rau cov pob khoom oversized (MTU> 1522 byte) ua, tuaj yeem txig tau paub 3G network cov ntaub ntawv sau thiab shunt daim ntawv thov.
Cov yam ntxwv muaj:
- Txhawb cov tsheb xa khoom los ntawm L2-L7 daim ntawv thov raws tu qauv.
- Txhawb 5-tuple lim los ntawm cov chaw nyob IP chaw nyob, chaw nres tsheb IP chaw nres nkoj, chaw nres nkoj qhov chaw, thiab kev cai thiab nrog daim npog ntsej muag.
- Txhawb cov tso zis thauj khoom ntsuas thiab tawm ntawm cov neeg tuaj ntawm lub tsev thiab homology.
- Txhawb kev lim thiab xa cov hlua khi.
- Txhawb kev sib ntsib. Xa mus rau thawj zaug N Pob Ntawv ntawm txhua ntu. Tus nqi ntawm n tuaj yeem sau tau.
- Txhawb kom muaj ntau tus neeg siv. Cov ntaub ntawv ntim cov ntaub ntawv txuas tib txoj cai tuaj yeem muab rau lwm lub sijhawm, lossis cov ntaub ntawv ntawm Outpect Interface tuaj yeem yog cov tshuaj matched thiab replicated, ua kom cov ntaub ntawv nkag ntawm ntau cov ntawv thov.
Kev Lag Luam Kev Lag Luam Cov Ntsiab Lus daws cov tshuaj haum
Nrog rau kev txhim kho sai ntawm cov ntaub ntawv thoob ntiaj teb thiab cov sib zog ntawm cov lag luam tau nthuav dav, thiab kev vam khom ntawm ntau yam kev lag luam ntawm cov ntaub ntawv hauv cov ntaub ntawv tau dhau los ua kev nce qib siab. Nyob rau tib lub sijhawm, cov lag luam lag luam sab hauv thiab sab nraud tiv thaiv, txhua yam kev saib xyuas cov ntaub ntawv, thiab tsis muaj peev xwm ua lag luam kev lag luam, thiab cov ntaub ntawv kev lag luam tsis txaus siab, thiab kev saib xyuas cov ntaub ntawv loj, thiab cov ntaub ntawv tsis muaj peev xwm loj hlob, txhua yam kev lag luam kev ruaj ntseg, thiab kev saib xyuas cov ntaub ntawv loj, Kev ua hauj lwm zoo, kev nqis peev siab, cov nyiaj tau los tsawg, kev saib xyuas lig thiab kev tswj xyuas nyuaj, cov ntaub ntawv cov ntaub ntawv yog qhov nyuaj los tswj.
