Figure 1 below illustrates an extract of the signaling messages which has been captured a tool from the link between Host A and Host B. Study the diagram carefully and answer the questions, with appropriate justifications. Host A INIT INIT ACK COOKIE ECHO INVITE 200 OK ACK RTP RTP ASCONF ASCONF ACK RTP RTP BYE SHUTDOWN SHUTDOWN ACK Host B New IP 10.20.0.8 acquired Figure 1: Signalling trace of a link between two core nodes Question 1 i. What are the signalling technologies which can be identified from the above extract? ii. Discuss whether the signaling technologies identified in the above part i, are capable of handling IP packets. Question 2 List down any missing signalling messages in the above capture, compared to the standard signaling flows defined in the relevant signaling techniques.
