TCP/IP was designed to provide the best-effort service. This puts the designer to difficulty in providing a real-time service solution over TCP/IP. In this paper we propose a protocol to calculate mean time offset of a set of servers with minimal chance of error introduced by the ...
Two security flaws named SegmentSmack and FragmentSmack were recently found in the Linux kernel. A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_col...
