The client generates random sequential numbers initially and sends them to the server. The initial
sequential numbers are synchronized with the clock and increments the counter every 4 msec.
The Server responds with an acknowledgement that increments the initial sequential number by one. The
ACK bit number is also changed to a "1" value. The "SYN" can have and identical "ACK" response for each
packet, thus, the server and the client can establish a connection.
