If your developer has been careful to test for the cases, and does the compares right, everything works fine across both 0x7FFFFFFF -> 0x80000000 and 0xFFFFFFFF -> 0x00000000. I've never seen Berkeley or Sun TCP source code, but I know for sure that a Sun 386i running SunOS 4.0.1 does not handle the second case right. I know for sure that our TCP does. The wrap case does matter, just leave a system monitor running on a telnet or X connection for a while (depends on what initial sequence number you get at open timethe fiorst time I tried it took a weekend) and use a LAN monitor to watch the Sun ignore acks after the boundary is reached...
