3.1.7.8 Receive Ping Response

The Receive Ping Response event is triggered when a packet is received on the UDP or SPX port on which the initiator is listening, as described in section 2.1.2. When this occurs, the protocol MUST perform the following actions:

• Let Response be a reference to a Ping Packet (section 2.2.7), initialized to refer to the Ping Response (section 2.1.2) received.

• If the Response.Signature field is not 0x5548, the protocol MUST ignore the packet and take no further action.

• If the Response.Cookie field has a different value from the PingCookie ADM element, the protocol MUST ignore the packet and take no further action.

• If a Send Ping Request (section 3.1.7.6) event is waiting for a Ping Response Timer Event (section 3.1.6.8) as specified in step 8 of section 3.1.7.6, the protocol MUST raise a Ping Response Processed (section 3.1.7.9) event. Otherwise, the protocol MUST ignore the packet and take no further action.
