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

["Martin Visser" <martinvisser99@xxxxxxxxx>]

jose,

this list is intended to discuss things specifically around wireshark, so you might be better off finding a network help mailing list for this sort of question

that said:-

The IP identification field is basically used to distinguish IP packets when the following other 3 parameters are all the same - source IP, dest IP and protocol. Thus as packets from A to B and A to C will have different dest IP address, you could in fact have the same identification field and still be able to distinguish packets.

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
