* 进行Internet编程时则不同,因为Internet上的路由器可能会将MTU设为不同的值. 如果我们假定MTU为1500来发送数据的,而途经的某个网络的MTU值小于1500字节,
* 最大的坏处就是PPPoE导致MTU变小了以太网的MTU是1500，再减去PPP的包头包尾的开销（8Bytes）， 就变成1492 bytes for PPPoE。1450 for PPTP
* connections 又因为UDP数据报的首部8字节,所以UDP数据报的数据区最大长度为1472字节. 这个1472字节就是我们可以使用的字节数。:)
* 那么系统将会使用一系列的机制来调整MTU值,使数据报能够顺利到达目的地,这样就会做许多不必要的操作. 鉴于
* Internet上的标准MTU值为576字节,所以我建议在进行Internet的UDP编程时. 最好将UDP的数据长度控件在540字节 (576-8-20-PPPoE8)以内.
