This paper proposes a "Step-Function" method to detect network attackers from using a long connection chain to hide their identities when they launch attacks. The objective of the method is to estimate the length of a connection chain based on the changes in packet round trip times. The key point to compute the round trip time of a connection chain is to match a Send and its corresponding Echo packet. The paper propose a conservative and a greedy matching algorithm to match TCP/IP packets in real-time. The first algorithm matches fewer packets but the quality of the matching is high. The second one matches more packets with some uncertainty on the correctness.
