CovNetwork Packet Broker(NPB), uas suav nrog 1G NPB, 10G NPB, 25G NPB, 40G NPB, 100G NPB, 400G NPB, thiabNetwork Test Access Port (TAP), yog ib qho khoom siv kho vajtse uas txuas ncaj qha rau hauv lub network cable thiab xa ib qho kev sib txuas lus hauv network mus rau lwm yam khoom siv.
Network Packet Brokers feem ntau yog siv hauv network intrusion detection systems (IDS), network detectors, thiab profilers. Chaw nres nkoj mirroring ntu. Hauv hom shunting, saib UTP txuas (tsis muaj qhov txuas tsis pom) tau muab faib ua ob ntu los ntawm TAP shunting ntaus ntawv. Cov ntaub ntawv shunted txuas nrog rau kev sib sau ua ke los sau cov ntaub ntawv rau Internet cov ntaub ntawv kev ruaj ntseg saib xyuas qhov system.
Network Packet Broker (NPB) ua dab tsi rau koj?
Cov yam ntxwv tseem ceeb:
1. Kev ywj pheej
Nws yog ib qho kev ywj pheej ntawm kev kho vajtse thiab tsis cuam tshuam rau kev thauj khoom ntawm cov khoom siv network uas twb muaj lawm, uas muaj txiaj ntsig zoo tshaj qhov chaw nres nkoj mirroring.
Nws yog ib qho khoom siv hauv kab, uas tsuas yog txhais tau tias nws yuav tsum tau xaim mus rau hauv lub network. Txawm li cas los xij, qhov no kuj muaj qhov tsis zoo ntawm kev qhia txog qhov tsis ua haujlwm, thiab vim tias nws yog ib qho khoom siv hauv online, lub network tam sim no yuav tsum tau cuam tshuam rau lub sijhawm xa mus, nyob ntawm seb nws tau xa mus rau qhov twg.
2. Pob tshab
Transparent 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 tag nrho cov khoom siv hauv lub network tam sim no, thiab pob tshab tag rau lawv. Tau kawg, qhov no kuj suav nrog kev xa mus los ntawm lub network shunt mus rau cov cuab yeej saib xyuas, uas tseem yog pob tshab rau lub network.
Txoj haujlwm ua haujlwm:
Lub tsheb shunting (kev faib tawm) raws li cov ntaub ntawv tawm tswv yim, rov ua dua, sib sau ua ke, lim, 10G POS cov ntaub ntawv hloov pauv los ntawm kev hloov pauv raws tu qauv rau kaum tawm megabytes LAN cov ntaub ntawv, raws li cov txheej txheem tshwj xeeb rau cov khoom sib npaug, cov zis tawm tib lub sijhawm los xyuas kom meej tias tag nrho cov pob ntawv ntawm tib qhov kev sib tham, lossis tib tus IP tso tawm tag nrho cov pob ntawv los ntawm tib tus neeg siv interface.
Functional Nta:
1. Kev hloov dua siab tshiab
Cov kev sib txuas lus hauv Is Taws Nem tseem ceeb siv los ntawm ISPs suav nrog 40G POS, 10G POS / WAN / LAN, 2.5G POS, thiab GE, thaum cov ntaub ntawv tau txais kev cuam tshuam siv los ntawm daim ntawv thov servers yog GE thiab 10GE LAN interfaces. Yog li ntawd, kev hloov pauv raws tu qauv feem ntau hais txog kev sib txuas lus hauv Is Taws Nem feem ntau yog hais txog kev hloov pauv ntawm 40G POS, 10G POS, thiab 2.5G POS rau 10GE LAN lossis GE, thiab kev sib txuas ntawm ob sab ntawm 10GE WAN thiab 10GE LAN thiab GE.
2. Kev sau thiab kev faib tawm cov ntaub ntawv.
Feem ntau daim ntawv thov sau cov ntaub ntawv pib rho tawm cov tsheb uas lawv saib xyuas thiab pov tseg cov tsheb uas lawv tsis quav ntsej txog. Cov ntaub ntawv khiav ntawm ib qho IP chaw nyob, raws tu qauv, thiab chaw nres nkoj yog muab rho tawm los ntawm tsib-tuple (qhov chaw IP chaw nyob, qhov chaw nyob IP chaw nyob, qhov chaw nres nkoj, chaw nres nkoj, thiab raws tu qauv) convergence. Thaum tso zis, tib qhov chaw, tib qhov chaw thiab cov khoom sib npaug ntawm cov zis tau ua kom ntseeg tau raws li qhov tshwj xeeb HASH algorithm.
3. Feature code filtering
Rau P2P tsheb thauj mus los, daim ntawv thov kaw lus tsuas yog tsom rau qee qhov kev khiav tsheb tshwj xeeb, xws li streaming media PPStream, BT, Thunderbolt, thiab cov ntsiab lus tseem ceeb ntawm HTTP xws li GET thiab POST, thiab lwm yam. Cov txheej txheem kev sib tw feature tuaj yeem siv rau kev rho tawm. thiab convergence. Lub diverter txhawb kev ruaj ntseg feature code filtering thiab floating feature code filtering. Ib tug floating feature code yog ib qho offset teev nyob rau hauv lub hauv paus ntawm ib tug ruaj qhov chaw feature code. Nws yog qhov tsim nyog rau cov ntawv thov uas qhia meej cov lej cim kom raug lim, tab sis tsis qhia meej qhov chaw tshwj xeeb ntawm tus lej cim.
4. Kev tswj hwm kev sib tham
Txheeb xyuas qhov kev sib kho tsheb thiab hloov kho qhov kev sib kho xa mus N tus nqi (N = 1 txog 1024). Ntawd yog, thawj N pob ntawv ntawm txhua qhov kev sib tham tau muab rho tawm thiab xa mus rau qhov rov qab-kawg daim ntawv thov kev txheeb xyuas, thiab cov pob ntawv tom qab N raug muab pov tseg, txuag cov peev txheej nyiaj siv ua haujlwm rau cov ntawv thov kev txheeb xyuas hauv qab. Feem ntau, thaum koj siv IDS los saib xyuas cov xwm txheej, koj tsis tas yuav ua txhua pob ntawv ntawm tag nrho cov kev sib tham; Hloov chaw, koj tsuas yog yuav tsum tau rho tawm thawj N pob ntawv ntawm txhua qhov kev sib tham kom ua tiav qhov xwm txheej tsom xam thiab saib xyuas.
5. Cov ntaub ntawv mirroring thiab replication
Lub splitter tuaj yeem paub qhov mirroring thiab replication ntawm cov ntaub ntawv ntawm cov zis interface, uas ua kom cov ntaub ntawv nkag tau ntawm ntau daim ntawv thov.
6. 3G network cov ntaub ntawv tau txais thiab xa mus
Cov ntaub ntawv sau thiab xa tawm ntawm 3G tes hauj lwm sib txawv ntawm cov qauv kev tshuaj xyuas network ib txwm muaj. Cov pob ntawv ntawm 3G tes hauj lwm raug xa mus rau ntawm cov pob txha caj qaum los ntawm ntau txheej txheej encapsulation. Pob ntawv ntev thiab encapsulation hom ntawv txawv ntawm cov pob ntawv ntawm cov tes hauj lwm sib xws. Lub splitter tuaj yeem txheeb xyuas qhov tseeb thiab ua tiav cov txheej txheem tunnels xws li GTP thiab GRE pob ntawv, pob ntawv MPLS multilayer, thiab pob ntawv VLAN. Nws tuaj yeem rho tawm IUPS signaling pob ntawv, GTP signaling packets, thiab Radius packets mus teev cov chaw nres nkoj raws li cov yam ntxwv ntawm pob ntawv. Tsis tas li ntawd, nws tuaj yeem faib cov pob ntawv raws li qhov chaw nyob IP sab hauv. Kev them nyiaj yug rau cov pob khoom loj (MTU> 1522 Byte) ua tiav, tuaj yeem paub zoo txog 3G network cov ntaub ntawv sau thiab shunt daim ntawv thov.
Feature Requirements:
- Txhawb kev faib tsheb khiav los ntawm L2-L7 daim ntawv thov raws tu qauv.
- Txhawb 5-tuple filtering los ntawm qhov tseeb qhov chaw nyob IP, chaw nyob IP chaw nyob, qhov chaw nres nkoj, chaw nres nkoj chaw, thiab raws tu qauv thiab nrog lub npog ntsej muag.
- Txhawb cov zis load ntsuas thiab tso zis homology thiab homology.
- Txhawb kev lim thiab xa tawm los ntawm cov kab cim.
- Txhawb kev tswj kev sib tham. Xa mus rau thawj N pob ntawv ntawm txhua qhov kev sib tham. Tus nqi ntawm N tuaj yeem teev tau.
- Txhawb rau ntau tus neeg siv. Cov ntawv ntim cov ntaub ntawv sib piv rau tib txoj cai tuaj yeem muab rau lwm tus neeg sab nrauv tib lub sijhawm, lossis cov ntaub ntawv ntawm cov khoom siv tawm tuaj yeem ua kom pom thiab rov ua dua, ua kom cov ntaub ntawv nkag mus ntawm ntau lub tshuab siv.
Kev Lag Luam Kev Lag Luam Nyiaj Txiag Kev daws teeb meem Advantage Solution
Nrog rau txoj kev loj hlob sai ntawm thoob ntiaj teb cov ntaub ntawv thev naus laus zis thiab kev sib sib zog nqus ntawm cov ntaub ntawv xov xwm, qhov ntsuas ntawm kev lag luam network tau maj mam nthuav dav, thiab kev vam khom ntawm ntau yam kev lag luam ntawm cov ntaub ntawv xov xwm tau nce siab. Nyob rau tib lub sijhawm, kev lag luam network ntawm kev tawm tsam sab hauv thiab sab nraud, kev tsis sib xws, thiab cov ntaub ntawv kev nyab xeeb kev hem thawj kuj tseem loj hlob, nrog rau ntau qhov kev tiv thaiv network, daim ntawv thov kev lag luam saib xyuas kev lag luam tau muab tso rau hauv kev ua lag luam, txhua yam kev soj ntsuam kev lag luam, cov cuab yeej tiv thaiv kev nyab xeeb. xa mus thoob plaws hauv lub network, yuav muaj cov ntaub ntawv pov tseg, saib xyuas qhov muag tsis pom kev, rov xyuas dua, network topology thiab teeb meem tsis zoo xws li tsis tuaj yeem tau txais cov ntaub ntawv lub hom phiaj zoo, ua rau kev soj ntsuam cov cuab yeej ua haujlwm qis. efficiency, siab peev, tsis tshua muaj nyiaj khwv tau los, lub lig txij nkawm thiab kev tswj kev nyuaj, cov ntaub ntawv kev pab yog nyuaj rau tswj.
