Why are TCP packets out of order?

What Causes Out-of-Order Packets? Multiple Paths: Out-of-order packets can be caused by data streams following multiple paths through a network (such as traffic traveling through the Internet), or via parallel processing paths within network equipment that are not designed to ensure that packet ordering is preserved.

What is out of order segment in TCP?

In computer networking, out-of-order delivery is the delivery of data packets in a different order from which they were sent. One of the functions of TCP is to prevent the out-of-order delivery of data, either by reassembling packets in order or requesting retransmission of out-of-order packets.

Next sequence number is sequence number plus TCP data payload length ACK number tells you what data has been received and what the next received sequence number should be What is a “spurious retransmission”?

How is an analysis done on a TCP capture file?

Analysis is done once for each TCP packet when a capture file is first opened. Packets are processed in the order in which they appear in the packet list. You can enable or disable this feature via the “Analyze TCP sequence numbers” TCP dissector preference.

Is it TCP that delivers data in the right order?

For TCP: Yes, it’s TCP that will deliver data in the right order to the application, which will/can cause delays if you have a lot of out-of-order packets, as TCP must wait until all required segments have arrived. Who will put the packets in a right order?
