[Winpcap-users] acquisition position

[Gianluca Varenni]

The traffic is captured between the IP stack and PPP, although you will also see some PPP-specific packets related to the PPP negotiation).

Hope this helps

                            Hello, 

                             
                            I would to know a which level Wireshark/Winpcap samples the IP packets.
                            I use a mobile phone as a modem (DUN). A flow control permits to adjust the data flow from the PC to the modem.

                            We have a downlink and a uplink data flow.
                            Because of this flow control, we can see that the downlink TCP data are not acknowledge immediately.

                            I would like to know where wireshark samples the data?
                            When the data leave the ipstack or when the data leave the PC?
                            Can I configure wireshark/winpcap to sample the packet a layer 3?
                            (I am affraid it could have some important delay between layer3 -> layer 2 -> layer 1)

                            (stack ip -> PPP -> USB -> modem) 


                            Thanks a lot. 
                            Michel
