| 1. A method of introducing in-band network management packets in a network comprising steps of:
constructing a packet including an IP header field, at least one additional header field, and a packet data field;
inserting a predetermined code in a field of said one additional header field, which code differentiates between a packet
that is an in-band network management packet and a user packet; and
providing the constructed packet to said network.
