Hello there, for example, N0---N1---N2, PingAgents on N0 and N2. Before Agent on N0 send ping-packet -----"send(pkt,0)" , the pkt->uid_ is 3; when Agent on N2 receive that ping-packet, the pkt->uid_ is -5, when it send reply message, the pkt->uid_ is 7; when Agent on N0 receive the reply-packet, the pkt->uid_ is -9.
