The following figure shows the successful cases of transition between the applicable logical states of MPTY. The state changes are caused by actions of the service provider.
Note that error cases are not shown in the diagram as they normally do not cause a state change. Additionally, some successful requests may not cause a state change. Hence they are not shown in the diagram.
