3.2.4 Outbound Proxy Details

This section gives details specific to an implementation of an outbound proxy. The state machine in the following diagram specifies the states and the transitions between them for the outbound proxy. Which event causes which transition is specified in section 3.2.4.5.

Figure 28: Outbound proxy state machine

The outbound proxy state machine is used when the outbound proxy is processing messages and PDUs coming from the network. When the state machine transitions to "Use Matching Channel State Machine", this means the state machine execution for this state machine stops and the current event (OUT_R1/A3 with Cookie Match) is interpreted as OUT_R2/A3 event for the state machine of the matching IN channel as specified in section 3.2.4.5.6.
