Detailed Description

TCP_Packet is an IP packet with additional TCP header fields. Messages of this type are used for communication between TCP sender and receiver (data and ACKs).

The class contains a segment of type TCP_Segment with sequence numbers for begin and end of the segment. This is only used in data packets (i.e. from sender to receiver) while there are also fields containing sequence number for the next expected segment (used to ACK data packets, i.e. from receiver to sender) and for the advertised receiver window.

TCP_Packet has an additional field for the session id which my be compared with the pair (source port, destination port) in a real world TCP/IP packet.

Furthermore, some debug info containing state information for TCP sender or receiver may be attached to the message.
