title="普通线路"></a>普通线路</h3><p>就是普通的出国线路，国内传输由电信163骨干网承载，线路省级/出国/国际骨干节点都以202.97开头，全程没有59.43开头的CN2节点。在出国线路上表现为拥堵，丢包率高。</p>
<h3 id="CN2"><a href="#CN2" class="headerlink" title="CN2"></a>CN2</h3><p>CN2全称为中国电信下一代承载网，英文Chinatelecom Next Carrier Network，缩写为CNCN，进一步缩写为CN2。</p>
<p><strong>CN2又分为CN2 GIA和CN2 GT：</strong></p>
<ul>
<li>CN2 GIA: 全称 Globla Internet Access, 是中国大陆与北美连接速度最快，负载最低的线路，GIA线路在国内省级路由中均介入59.43开头的CN2节点，负载低，质量高，速度快，价格高。</li>
<li>CN2 GT：是电信 CN2 产品线中的 Global Transit（GIS-Global Internet Service）的产品，CN2 GT 到中国国际出口有自己的单独线路，但是进入国内还是使用的 163 出口。省级/出国节点为 202.97 开头（202.97 节点是中国电信的 163 骨干网的节点），国际骨干节点有 2～4 个 59.43 开头的 CN2 节点。</li>
</ul>
<h2 id="一图看懂CN2的区别"><a href="#一图看懂CN2的区别" class="headerlink" title="一图看懂CN2的区别"></a>一图看懂CN2的区别</h2><p>简单说三条线路的区别就是：</p>
<ol>
<li>CN2 GIA是本地骨干有CN2网络的话直接介入59.43不会走202.97。</li>
<li>CN2 GT话就是出口走59.43，国内还是202.97。</li>
<li>普通163线路就是全程202.97</li>
</ol>
