Draw a sequence diagram for the following scenario. In a network, two nodes communicate with each other. These are the sequence. 1) Node J sends ping message to Node L 2) Node L sends ICMP echo reply to node L. Now Node A is having the MAC address of Node L. 3) Node J starts TCP handshake with Node L by sending SYN message. 4) Node L sends (SYN+ACK) back to node J. 5) Node J sends the ACK to Node L.
