I have installed Winpcap 3.1 Beta for support in order to capture from a PPP interface. What i do is, I capture from the PPP interface through my LIBPCAP program and send the traffic to another Ethernet interface in my computer. Then i connect this Ethernet Interface to another Ethernet Interface at another computer where i monitor it through Wireshark.</p><p style="margin-top: 0px; margin-right: 0px; margin-bottom: 1em; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; font-size: 14px; vertical-align: baseline; background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; clear: both; word-wrap: break-word; background-position: initial initial; background-repeat: initial initial; ">So in short my PPP-Ethernet Bridge is on computer 1.

But when i use my LIBPCAP program to capture and relay traffic and check the traffic on computer 2 using Wireshark it gives jumps of 0.5seconds delay after some packets. This is quite unexplainable to me. I dont understand how wireshark PPP direct capture on computer 1 does not give delay and LIBPCAP program is giving delay.</p><p style="margin-top: 0px; margin-right: 0px; margin-bottom: 1em; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; font-size: 14px; vertical-align: baseline; background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; clear: both; word-wrap: break-word; background-position: initial initial; background-repeat: initial initial; ">I have checked my bridge for Ethernet to Ethernet relaying and there is no delay like the one i am experiencing in case of PPP-Ethernet. a higher delay between packets is acceptable but such a BIG delay after a couple of packets is unacceptable.
