Ketika kita telah selesai membangun sebuah Network Link, pertanyaan yang kerap muncul adalah bagaimana mengukur performance dari link tersebut, dalam istilah commisioning test network ada muncul istilah – (BERT) A bit error rate tester , nah istilah BERT test ini sering kita dengar dilingkungan ISP, NAP, Network Provider, tools untuk pengujian ini pun bermacam-macam, sebut saja bandwidthtes Mikrotik,Iperf, NetIQ Cheriot,tGEN (traffik Generator), Pathchar, dsb.<\/p>\n

\"\"<\/a>Iperf adalah salah satu tool untuk mengukur troughput bandwidth dalam sebuah link network, agar bisa dilakukan pengukuran diperlukan Iperf yang terinstall point to point, baik disisi server maupun client. Iperf sendiri bisa digunakan untuk mengukur performance link dari sisi TCP maupun UDP. diubuntu bisa menggunakan perintah apt-get install iperf, di FreeBSD bisa menggunakan perintah pkg_add iperf. Untuk ujicoba pastikan bahwa komputer tujuan terinstall dengan baik ipperf dan client testnya.<\/p>\n

<\/a>Syntax yang biasa digunakan adalah sebagai berikut,
\nIperf tests:<\/p>\n

no arg. Default settings<\/em>
\n-b Data format<\/em>
\n-r Bi-directional bandwidth<\/em>
\n-d Simultaneous bi-directional bandwidth<\/em>
\n-w TCP Window size<\/em><\/p>\n
