			<content:encoded><![CDATA[<div id="cgDn">    价绍五个实用的,流行的,能从应用层和网络层用来进行网络测试或网络排错或进行衡量TCP/IP网络性的一些工具.</div>
<div> </div>
<div>一.测量网络性能的五项指标是：</div>
<div>
<ul>
<li>可用性（availability）</li>
<li>响应时间（response time）</li>
<li>网络利用率（network utilization）</li>
<li>网络吞吐量（network throughput）</li>
<li>网络带宽容量（network bandwidth capacity</li>
</ul>
</div>
<div>更多了解,请参考IBM <a href="http://www.ibm.com/developerworks/cn">developerWorks 中国</a><span>   </span><a href="http://www.ibm.com/developerworks/cn/linux/l-netperf/">netperf 与网络性能测量</a></div>
<div>
<p>这里特别推荐一个带宽测试工具 <a href="http://code.google.com/p/xjperf/">xjperf</a>  和一个用测试网络丢包率,响应时间,路由稳定性,的工具<a href="http://www.bitwizard.nl/mtr/">MTR</a></p>
<p> </p>
<p><strong>以下内容参考<a href="http://compnetworking.about.com/od/networkperformance/TCPIP_Network_Performance_Benchmarks_and_Tools.htm">这里</a></strong></p>
<p><strong> </strong></p>
<p><strong><a href="http://www.netperf.org/">Netperf</a></strong><br />
      An engineer at Hewlett-Packard developed Netperf to help the Unix network benchmarking community many years ago, and this benchmarking tool remains popular in Unix / Linux environments today.</p>
<p><strong><a href="http://clk.about.com/?zi=1/XJ/Ya&amp;sdn=compnetworking&amp;cdn=compute&amp;tm=1811&amp;gps=50_299_1252_829&amp;f=00&amp;tt=14&amp;bt=0&amp;bts=0&amp;zu=http%3A//clk.about.com/%3Fzi%3D1/XJ/Ya%26sdn%3Dcompnetworking%26cdn%3Dcompute%26tm%3D19%26gps%3D31_296_1252_829%26f%3D00%26tt%3D14%26bt%3D0%26bts%3D0%26zu%3Dhttp%253A//www.ittc.ku.edu/netspec/">NetSpec</a></strong><br />
      NetSpec strives to implement more realistic network performance testing scenarios than the standard utilities by acocunting for variable traffic flows. NetSpec is an academic research project that includes source code.</p>
<p><a href="http://dsd.lbl.gov/~boverhof/nettest.html"><strong>Nettest</strong><br />
</a>     Nettest is a simple latency and bendwidth performance benchmark for point-to-point TCP connections on Solaris and Linux.</p>
<p><strong><a href="http://www.pcausa.com/Utilities/pcattcp.htm">TTCP</a></strong><br />
      The Test TCP (TTCP) Benchmarking Tool measures network performance at the TCP and UDP level. Originally developed for Unix, TTCP has also been ported to Windows and other operating systems.</p>
<p><a href="http://www.ai3.net/products/dbs/"><strong>DBS - Distributed Benchmark System</strong><br />
</a>      The Distributed Benchmark System (DBS) is a performance benchmark tool for TCP/IP networks that attempts to expand on the capability of other tools in this category. DBS supports retransmission control and congestion avoidance performance evaluation across multiple dynamic connections.</p>
