1、端口 在Skype的连接属性对话框中可以设置监听的端口号，在安装的时候Skype会随机的选择一个端口作为监听的端口，这一点与HTTP协议等不同，Skype没有默认的服务端口。同时，它还会打开对80和443端口的监听。80是常见的HTTP服务默认端口，而443则是HTTPS服务的默认端口。 2、主机列表(HC，Host Cache) 这里的主机指的是可以提供踏板及广播服务的Super Node(SN)。通常它被存储在注册表里的：HKEY_CURRENT_USER / SOFTWARE / SKYPE / PHONE / LIB / CONNECTION / HOSTCACHE 中.一般情况下，运行两天后，HC中会有约200个机器地址及对应的端口号。
晚上在看Salman A. Baset和Henning Schulzrinne写的《An Analysis of the Skype Peer-to-Peer Internet Telephony Protocol》。因为Skype的通讯协议是不公开的，而且通讯内容是加过密的，这两位完全在实验的基础上对Skype的通讯机制进行分析，分析结果很有参考价值。 通过分析得出的结论主要有三个： 1、Skype的通话质量较MSN和Yahoo的即时通信工具要好； 2、可以无缝的在NATs和防火墙后使用； 3、安装使用起来确实非常简单。
