Why TCP_MAX_SACK == 3 ?

2005-03-07 Thread Noritoshi Demizu
In netinet/tcp.h, TCP_MAX_SACK is defined as follows. #define TCP_MAX_SACK3 /* MAX # SACKs sent in any segment */ Shouldn't it be 4? If a peer node does not use TCP timestamps option, four SACK blocks can be sent. For example, if my memory serves correctly, Microsoft Windows does not
