WebProtocols such as HTTP or TLS are likely to span multiple TCP segments. The TCP protocol preference “Allow subdissector to reassemble TCP streams” (enabled by default) makes it possible for Wireshark to collect a contiguous sequence of TCP segments and hand them over to the higher-level protocol (for example, to reconstruct a full HTTP message). WebIf that delta is less than the initial round-trip time (or less than 3 ms when the 3-way-handshake was not captured), it is considered an out-of-order packet. So in the case above, the proper order for packets from X to arrive would have been: You could say that only frame 12 was received out-of-order, the rest was fine.
