Were that packets of a cheap embeded device? Sounds like a buggy TCP stack to me.

Thanks! But previously I saw a tcp stream where there are several TCP connections (I mean mutiple SYN-SYN/ACK-ACK handshakes)

Nangergong,

A TCP stream is a single connection between two IP addresses, between the two same ports. If you see the beginning you'll see the SYN-SYN/ACK-ACK handshake, an will also see the sequence numbers increasing. Some protocols like HTTP/1.1 can have multiple higher level conversations on the one connection, so I am not sure that is what you might be seeing?

HI, all:

    In wireshark there is an option "Follow the TCP stream", I'm wondering what does it mean? it seems that in such a TCP stream there are multiple TCP connections.
