This changed principle is: Normally the circumstance falls, the number with acquiescent TCP/IP accepts the size of buffer to be 576 byte according to transmitting unit, if set the size of this buffer more greatly, once a certain TCP/IP in group when data happening is wrong, all cent inter block in buffer of so whole data is allowed, will be lost and undertake; undertakes transmission afresh ceaselessly apparently conveying afresh, can affect ADSL to transmit the efficiency of data greatly.

这个更改的原理是：通常情况下，TCP/IP默认的数据传输单元接受缓冲区的大小为576字节，要是将这个缓冲区的大小设置得比较大的话，一旦某个TCP/IP分组数据发生错误时，那么整个数据缓冲区中的所有分组内容，都将被丢失并且进行重新传送；显然不断地重新进行传输，会大大影响ADSL传输数据的效率。
