Nkag siab Backplane Bandwidth
Backplane bandwidth, tseem hu ua switching peev, yog qhov siab tshaj plaws cov ntaub ntawv los ntawm kev hloov lub interface processor thiab cov ntaub ntawv tsheb npav. Xav txog nws raws li tag nrho cov kab ntawm txoj kab hla hla-ntau txoj kab txhais tau tias muaj tsheb khiav ntau dua. Muab hais tias tag nrho cov chaw nres nkoj sib txuas lus dhau los ntawm lub dav hlau rov qab, qhov bandwidth no feem ntau ua raws li lub hwj chim thaum lub sij hawm muaj tsheb ntau. Qhov bandwidth ntau dua, cov ntaub ntawv ntau tuaj yeem ua haujlwm ib txhij, ua rau cov ntaub ntawv sib pauv sai. Hloov pauv, txwv bandwidth yuav ua rau cov ntaub ntawv ua haujlwm qeeb.
Cov qauv tseem ceeb:
Backplane Bandwidth = Tus naj npawb ntawm cov chaw nres nkoj × Chaw nres nkoj tus nqi × 2
Piv txwv li, ib qho kev hloov nruab nrog 24 chaw nres nkoj ua haujlwm ntawm 1 Gbps yuav muaj lub dav hlau rov qab bandwidth ntawm 48 Gbps.
Packet Forwarding nqi rau txheej 2 thiab txheej 3
Cov ntaub ntawv hauv lub network muaj ntau cov pob ntawv, txhua qhov xav tau kev pab rau kev ua haujlwm. Tus nqi xa mus (throughput) qhia tias muaj pes tsawg pob ntawv tuaj yeem ua haujlwm hauv ib lub sijhawm tshwj xeeb, tsis suav nrog pob ntawv poob. Qhov kev ntsuas no zoo ib yam li kev khiav tsheb khiav ntawm tus choj thiab yog qhov kev ntsuas kev ua haujlwm tseem ceeb rau txheej 3 keyboards.
Qhov tseem ceeb ntawm Kab-Speed Switching:
Txhawm rau tshem tawm cov kev tsis sib haum xeeb hauv lub network, cov keyboards yuav tsum ua tiav txoj kab-ceev hloov pauv, txhais tau tias lawv qhov kev hloov pauv hloov pauv qhov sib kis ntawm cov ntaub ntawv tawm.
Overput Calculation:
Throughput (Mpps) = Number of 10 Gbps Ports × 14.88 Mpps + Number of 1 Gbps Ports × 1.488 Mpps + Number of 100 Mbps Ports × 0.1488 Mpps.
Ib qho kev hloov pauv nrog 24 1 Gbps cov chaw nres nkoj yuav tsum ncav cuag qhov tsawg kawg nkaus ntawm 35.71 Mpps los pab txhawb kev sib pauv pob ntawv tsis muaj kev cuam tshuam.
Scalability: Npaj rau yav tom ntej
Scalability suav nrog ob qhov loj me:
Txheej 4 Hloov: Txhim kho Network Kev Ua Haujlwm
Txheej 4 kev hloov pauv nrawm nkag mus rau cov kev pabcuam network los ntawm kev ntsuas tsis yog MAC chaw nyob lossis IP chaw nyob, tab sis kuj tseem TCP / UDP daim ntawv thov chaw nres nkoj. Tsim tshwj xeeb rau cov ntawv thov kev kub ceev Intranet, txheej 4 hloov pauv tsis yog tsuas yog thauj khoom sib npaug xwb tab sis kuj muab kev tswj raws li hom ntawv thov thiab tus neeg siv ID. Qhov no ua haujlwm txheej 4 hloov ua qhov zoo tshaj plaws kev nyab xeeb nets tiv thaiv tsis tau tso cai nkag mus rau cov servers rhiab heev.
Module Redundancy: Ua kom ntseeg tau
Redundancy yog qhov tseem ceeb rau kev tswj xyuas lub network zoo. Cov khoom siv hauv network, suav nrog cov hloov pauv tseem ceeb, yuav tsum muaj peev xwm rov ua dua kom txo qis qis qis thaum ua tsis tiav. Cov khoom tseem ceeb, xws li kev tswj hwm thiab fais fab modules, yuav tsum muaj kev xaiv tsis ua haujlwm los xyuas kom muaj kev ruaj ntseg network.
Routing Redundancy: Boosting Network Stability
Ua raws li HSRP thiab VRRP raws tu qauv tau lees tias muaj txiaj ntsig zoo ntawm kev sib npaug thiab cov thaub qab kub rau cov khoom siv tseem ceeb. Nyob rau hauv qhov kev tshwm sim ntawm ib tug hloov tsis ua hauj lwm nyob rau hauv ib tug tseem ceeb los yog dual aggregation hloov teeb, lub kaw lus yuav sai sai hloov mus rau backup ntsuas, kom ntseeg tau seamless redundancy thiab tswj tag nrho cov kev ncaj ncees network.
Xaus
Kev koom ua ke cov kev hloov pauv tseem ceeb no rau hauv koj lub network engineering repertoire tuaj yeem txhim kho koj txoj haujlwm ua haujlwm tau zoo thiab ua haujlwm tau zoo hauv kev tswj hwm kev lag luam hauv network. Los ntawm kev nkag siab cov ntsiab lus xws li backplane bandwidth, pob ntawv xa mus rau tus nqi, scalability, txheej 4 hloov, redundancy, thiab routing raws tu qauv, koj tso koj tus kheej ua ntej ntawm qhov nkhaus hauv lub ntiaj teb cov ntaub ntawv nce ntxiv.
