Wireshark · Wireshark-users: [Wireshark-users] Transmission time and a doubt

[jose john <jose.john@xxxxxxxxx>]

Hi There,
     What is this transmission parameter in the frame really means?

     Suppose I have a network like
     lapA-----R1-----R2-----lapB
                           |-------lapC
                                               
    I am doing a tracert to B and C from A.           
    Is there any possibility that a frame from A to B and another frame from A to C can have same IP identification field. Or what all are the possible scenarios where in which we can have the IP Identification number of two frames can be same?

Thanks,
Jose John
