Sequence # and Next Expected # are the same

[RADIOMEN]

When analyzing the packets I see that a transmission error occurs between two servers when the TCP Sequence Number is the as the TCP Next Expected Seq Number.

What is wrong?
I have never seen this before, any input?

Thanks,
P.

That's just normal behavior in sequnecing tcp segments. The seq. no. represents the (tcp) byte number sent on that circuit. E.g. if a server send an ack without any data the seq np and the next expectet is equal....
hope this helps, who
