Txhawm rau kuaj xyuas qhov nrawm hauv lub network hauv cheeb tsam, koj tuaj yeem hloov cov ntaub ntawv ntau ntawm ib lub computer mus rau lwm lub. Los ntawm ntsuas ntsuas lub sij hawm xa mus, nws yooj yim los txiav txim qhov nrawm. Txawm li cas los xij, nws zoo dua yog siv cov program tshwj xeeb ntsuas ntsuas nrawm.
Tsim nyog
2 khoos phis tawj, IPERF program
Cov Lus Qhia
Kauj ruam 1
Txhawm rau kuaj qhov LAN ceev uas siv IPERF, koj yuav tsum muaj:
• 2 khoos phis tawj (ib tus neeg rau zaub mov, lwm tus neeg siv khoom siv) txuas nrog lub network thiab nrog tus IP teev kev cai;
• nws tus kheej, iperf (Linux, Windows versions) ntawm txhua lub khoos phis tawm, ntxiv rau, lawv yuav tsum ping;
• txhawm rau ntsuas qhov chaw nres nkoj tshwj xeeb (TCP lossis UDP), koj yuav tsum tau qhib kev nkag mus rau lub pob hlau no.
Kauj ruam 2
Txhawm rau kom raug qhov tseeb ntawm baud tus ntsuas ntsuas ntawm ob lub khoos phis tawm, koj yuav tsum:
• Kaw txhua qhov kev zov me nyuam uas xa cov ntaub ntawv hauv network;
• Kaw tag nrho cov kev pabcuam uas xav tau los muab lub peev xwm xav tau ntawm tus processor thiab lub cim xeeb;
• Teeb cov kev tso cai tsim nyog nyob rau hauv kev teeb tsa hluav taws teeb rau qhov chaw kuaj ntawd;
• Sau txog cov txiaj ntsig tau los.
Kauj ruam 3
Thaum tag nrho cov saum no ua tiav, tom qab ntawd nws tsim nyog pib txoj haujlwm. Ua ntej cov neeg rau zaub mov sab, ces cov neeg siv khoom sab. Rau cov neeg rau zaub mov, pib iperf nrog cov kev ntsuas hauv qab no: iperf -s -p 80 (-s yog lub computer server, -p 80 qhia tias TCP chaw nres nkoj 80 raug sim. Los sim UDP chaw nres nkoj, teeb lub -u chij: iperf -s -u - p 80).
Kauj ruam 4
Ntawm cov neeg siv lub computer, iperf pib nrog cov kev ntsuas hauv qab no: iperf -c 198.168.15.3 -p 80 -t 120 (-c qhia txog tus neeg siv cov feem, 198.168.15.3 yog ip-chaw nyob ntawm lub server server, -t 120 qhia LAN lub sijhawm kuaj thaum lub sijhawm 120 vib nas this (2 feeb)).
Kauj ruam 5
LAN ceev kuaj tuaj yeem ua tiav ntau txoj hauv kev.
Hloov cov ntaub ntawv loj (700MB lossis ntau dua) ntawm FTP lossis HTTP thiab ntsuas lub sijhawm hloov ntaub ntawv, tom qab ntawd faib cov ntawv loj hauv megabytes los ntawm lub sijhawm siv rau kev hloov mus (hauv vib nas this) thiab, raws li, tau txais cov channel ceev ntawm megabytes ib ob,
Kauj Ruam 6
Txhawm rau kuaj qhov ceev ntawm LAN, siv tshwj xeeb. cov kev pab cuam. Piv txwv, cov program yog IPERF (iperf.sourceforge.net). Koj tuaj yeem paub txog nws hauv Is Taws Nem.
