<abstract>
<t>The TCP Big Window option discussed in RFC 1106 will not work properly in an Internet environment which has both a high bandwidth * delay product and the possibility of disordering and duplicating packets.  In such networks, the window size must not be increased without a similar increase in the sequence number space.  Therefore, a different approach to big windows should be taken in the Internet.</t></abstract></front>
