First, I wanna calculate the one-way delay by time_stamp in TCP Acks; ie, rcv_tsval & rvc_tsecr in tcp_input.c. But I am not quite sure in which functions, ex. tcp_rcv_established, the two values (rcv_tsval & rvc_tsecr) are what I want. Second, I want to use ECN as an indicator and add some conditions. But I really cannot figure out what is going on in tcp_input.c. Could anyone give me some hints please? Thanks. YuZen
