Iperf網(wǎng)絡(luò)測(cè)試工具

iperf

Iperf是一款基于TCP/IP和UDP/IP的網(wǎng)絡(luò)性能測(cè)試工具，可以用來測(cè)量網(wǎng)絡(luò)帶寬和網(wǎng)絡(luò)質(zhì)量，提供網(wǎng)絡(luò)延遲抖動(dòng)、數(shù)據(jù)包丟失率、最大傳輸單元等統(tǒng)計(jì)信息。

[kmgKMG] Indicates options that support a k,m,g,K,M or G suffix
Lowercase format characters are 10^3 based and uppercase are 2^n based
(e.g. 1k = 1000, 1K = 1024, 1m = 1,000,000 and 1M = 1,048,576)

The TCP window size option can be set by the environment variable
TCP_WINDOW_SIZE. Most other options can be set by an environment variable
IPERF_<long option name>, such as IPERF_BANDWIDTH.
