LubTus Neeg Sawv Cev Pob Khoom Hauv Network(NPB), uas suav nrog cov feem ntau siv 1G NPB, 10G NPB, 25G NPB, 40G NPB, 100G NPB, 400G NPB, thiabChaw Nkag Mus Rau Kev Xeem Network (TAP), yog ib lub cuab yeej kho vajtse uas txuas ncaj qha rau hauv lub network cable thiab xa ib daim ntawm kev sib txuas lus network mus rau lwm cov khoom siv.
Cov Network Packet Brokers feem ntau siv rau hauv cov txheej txheem nrhiav kev nkag mus rau hauv network (IDS), cov cuab yeej nrhiav network, thiab cov profilers. Kev sib tham mirroring chaw nres nkoj. Hauv hom shunting, qhov txuas UTP uas tau saib xyuas (qhov txuas tsis muaj lub ntsej muag) raug muab faib ua ob ntu los ntawm lub cuab yeej TAP shunting. Cov ntaub ntawv shunted txuas nrog lub interface sau los sau cov ntaub ntawv rau lub kaw lus saib xyuas kev ruaj ntseg ntawm cov ntaub ntawv hauv Is Taws Nem.
Network Packet Broker (NPB) ua dab tsi rau koj?
Cov Nta Tseem Ceeb:
1. Ywj siab
Nws yog ib daim kho vajtse ywj pheej thiab tsis cuam tshuam rau qhov hnyav ntawm cov khoom siv network uas twb muaj lawm, uas muaj qhov zoo dua li qhov chaw nres nkoj mirroring.
Nws yog ib lub cuab yeej hauv kab, uas tsuas yog txhais tau tias nws yuav tsum tau txuas 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 nws yog lub cuab yeej online, lub network tam sim no yuav tsum tau cuam tshuam thaum lub sijhawm xa tawm, nyob ntawm qhov chaw uas nws tau xa tawm.
2. Pob tshab
Txhais tau tias yog tus taw qhia rau lub network tam sim no. Tom qab nkag mus rau lub network shunt, nws tsis muaj kev cuam tshuam rau txhua lub cuab yeej hauv lub network tam sim no, thiab nws yog qhov pom tseeb rau lawv. Tau kawg, qhov no kuj suav nrog cov tsheb khiav los ntawm lub network shunt mus rau lub cuab yeej saib xyuas, uas kuj yog qhov pom tseeb rau lub network.
Txoj cai ua haujlwm:
Kev faib tsheb khiav (faib tawm) raws li cov ntaub ntawv nkag, rov ua dua, sau ua ke, lim dej, 10G POS cov ntaub ntawv hloov pauv los ntawm kev hloov pauv protocol mus rau kaum tawm megabytes LAN cov ntaub ntawv, raws li cov algorithm tshwj xeeb rau kev sib npaug ntawm qhov tso zis, cov zis tib lub sijhawm kom ntseeg tau tias tag nrho cov pob ntawv ntawm tib lub sijhawm, lossis tib IP tso zis tag nrho cov pob ntawv los ntawm tib tus neeg siv interface.
Cov yam ntxwv ua haujlwm:
1. Kev hloov pauv ntawm cov txheej txheem
Cov kev sib txuas lus hauv Is Taws Nem uas siv los ntawm ISP suav nrog 40G POS, 10G POS/WAN/LAN, 2.5G POS, thiab GE, thaum cov kev sib txuas lus txais cov ntaub ntawv siv los ntawm cov servers application yog GE thiab 10GE LAN interfaces. Yog li ntawd, kev hloov pauv protocol feem ntau hais txog ntawm 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 mus rau 10GE LAN lossis GE, thiab kev sib pauv ob txoj kev ntawm 10GE WAN thiab 10GE LAN thiab GE.
2. Kev sau thiab faib cov ntaub ntawv.
Feem ntau cov ntawv thov sau cov ntaub ntawv feem ntau rho tawm cov tsheb khiav uas lawv txhawj txog thiab pov tseg cov tsheb khiav uas lawv tsis txhawj txog. Cov tsheb khiav ntawm ib qho chaw nyob IP tshwj xeeb, protocol, thiab port yog rho tawm los ntawm tsib-tuple (qhov chaw nyob IP, qhov chaw nyob IP, qhov chaw nres nkoj, qhov chaw nres nkoj, thiab protocol) kev sib sau ua ke. Thaum tso zis, tib qhov chaw, tib qhov chaw thiab qhov sib npaug ntawm cov khoom tso zis raug lees paub raws li HASH algorithm tshwj xeeb.
3. Kev lim cov lej nta
Rau kev sau cov tsheb khiav P2P, lub kaw lus thov tsuas yog tsom mus rau qee qhov kev khiav tsheb tshwj xeeb, xws li streaming media PPStream, BT, Thunderbolt, thiab cov lus tseem ceeb ntawm HTTP xws li GET thiab POST, thiab lwm yam. Txoj kev sib phim cov lej tshwj xeeb tuaj yeem siv rau kev rho tawm thiab kev sib sau ua ke. Lub diverter txhawb nqa kev lim cov lej tshwj xeeb qhov chaw ruaj khov thiab kev lim cov lej tshwj xeeb ntab. Cov lej tshwj xeeb ntab yog qhov offset teev tseg raws li qhov chaw ruaj khov. Nws yog qhov tsim nyog rau cov ntawv thov uas teev cov lej tshwj xeeb kom raug lim, tab sis tsis teev qhov chaw tshwj xeeb ntawm cov lej tshwj xeeb.
4. Kev tswj xyuas kev sib tham
Txheeb xyuas cov tsheb khiav ntawm lub rooj sib tham thiab teeb tsa tus nqi N rau kev xa mus rau lub rooj sib tham (N=1 txog 1024). Qhov ntawd yog, thawj N pob ntawm txhua lub rooj sib tham raug rho tawm thiab xa mus rau lub kaw lus tshuaj xyuas daim ntawv thov tom qab, thiab cov pob tom qab N raug pov tseg, txuag cov peev txheej rau lub platform tshuaj xyuas daim ntawv thov tom qab. Feem ntau, thaum koj siv IDS los saib xyuas cov xwm txheej, koj tsis tas yuav ua tiav tag nrho cov pob ntawm tag nrho lub rooj sib tham; hloov chaw, koj tsuas yog yuav tsum rho tawm thawj N pob ntawm txhua lub rooj sib tham kom ua tiav qhov kev tshuaj xyuas thiab kev saib xyuas cov xwm txheej.
5. Kev sib piv cov ntaub ntawv thiab kev rov ua dua
Lub splitter tuaj yeem paub txog qhov mirroring thiab replication ntawm cov ntaub ntawv ntawm cov zis interface, uas ua kom cov ntaub ntawv nkag mus rau ntau daim ntawv thov systems.
6. Kev nrhiav thiab xa cov ntaub ntawv hauv 3G network
Cov ntaub ntawv sau thiab faib tawm ntawm 3G tes hauj lwm txawv ntawm cov qauv tshuaj xyuas tes hauj lwm ib txwm muaj. Cov pob ntawv ntawm 3G tes hauj lwm raug xa mus rau ntawm cov kev sib txuas rov qab los ntawm ntau txheej ntawm encapsulation. Qhov ntev ntawm pob ntawv thiab hom encapsulation txawv ntawm cov pob ntawv ntawm cov tes hauj lwm sib xws. Lub splitter tuaj yeem txheeb xyuas thiab ua cov txheej txheem tunnel xws li GTP thiab GRE pob ntawv, ntau txheej MPLS pob ntawv, thiab VLAN pob ntawv. Nws tuaj yeem rho tawm IUPS signaling pob ntawv, GTP signaling pob ntawv, thiab Radius pob ntawv mus rau cov chaw nres nkoj tshwj xeeb 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 txhawb nqa rau cov pob ntawv loj (MTU> 1522 Byte) ua tiav, tuaj yeem ua tiav 3G network cov ntaub ntawv sau thiab daim ntawv thov shunt.
Cov Kev Cai Tshwj Xeeb:
- Txhawb kev faib tsheb khiav los ntawm L2-L7 daim ntawv thov protocol.
- Txhawb 5-tuple lim los ntawm qhov chaw nyob IP tseeb, qhov chaw nyob IP, qhov chaw nres nkoj, qhov chaw nres nkoj, thiab protocol thiab nrog lub ntsej muag.
- Txhawb nqa qhov tso zis load balancing thiab cov zis homology thiab homology.
- Txhawb kev lim dej thiab xa mus los ntawm cov cim kab.
- Txhawb kev tswj hwm kev sib tham. Xa mus rau thawj N pob ntawm txhua qhov kev sib tham. Tus nqi ntawm N tuaj yeem teev tseg.
- Kev txhawb nqa rau ntau tus neeg siv. Cov ntaub ntawv pob khoom sib phim tib txoj cai tuaj yeem muab rau tus neeg thib peb tib lub sijhawm, lossis cov ntaub ntawv ntawm qhov tso zis interface tuaj yeem mirrored thiab replicated, kom ntseeg tau tias cov ntaub ntawv nkag mus rau ntau lub tshuab thov.
Kev daws teeb meem kev lag luam nyiaj txiag Kev daws teeb meem Kev daws teeb meem zoo
Nrog rau kev loj hlob sai ntawm kev siv tshuab thev naus laus zis thoob ntiaj teb thiab kev siv tshuab thev naus laus zis ntau ntxiv, qhov loj ntawm lub network lag luam tau nthuav dav maj mam, thiab kev vam khom ntawm ntau yam kev lag luam rau lub kaw lus ntaub ntawv tau nce siab. Tib lub sijhawm, lub network lag luam ntawm kev tawm tsam sab hauv thiab sab nraud, kev tsis sib xws, thiab kev hem thawj rau kev ruaj ntseg ntawm cov ntaub ntawv kuj tseem loj hlob, nrog rau kev tiv thaiv network ntau heev, daim ntawv thov kev saib xyuas kev lag luam tau muab tso rau hauv kev ua haujlwm sib law liag, txhua yam kev saib xyuas kev lag luam, cov khoom siv tiv thaiv kev nyab xeeb tau xa mus thoob plaws hauv lub network, yuav muaj kev pov tseg ntawm cov ntaub ntawv, saib xyuas qhov chaw dig muag, rov ua dua kev saib xyuas, network topology thiab teeb meem tsis sib xws xws li tsis tuaj yeem tau txais cov ntaub ntawv lub hom phiaj zoo, ua rau cov khoom siv saib xyuas ua haujlwm tsis zoo, kev nqis peev ntau, cov nyiaj tau los tsawg, kev txij nkawm lig thiab kev tswj hwm nyuaj, cov ntaub ntawv nyuaj rau tswj.
