2.6.4 Pending Answer Timer

Pending Answer Timers specify the amount of time the DSR waits for an Answer after sending a Request to a Peer Node. DSR allows for the specification of up to16 pending answer timers that can be associated with the transactions/peers. This allows for different peers to respond to answers with different response times.

This feature addresses the ability to configure the Pending Answer Timer in the DSR which can then be optionally associated to a diameter transaction in several ways (in precedence order):

• If the Transaction Configuration Group is select on the ingress peer node configuration object, then the transaction configuration group is used and the longest/strongest match criteria is applied for request message parameters to compare and if a match is found, then the PAT assigned to the transaction set defined under this group.
• The PAT from the ROS assigned to the ingress peer node is used.
• The PAT assigned to the egress peer node is used.
• The PAT assigned to the default TCG is used.
• The System default PAT is used.
