The purpose of Time stamping function is to measure the duration of transaction and request processing.
The Access point modules shall set the Access_ ID_ obtained_ time in the Transaction start_ request message.
For the other modules, time stamping shall be activated and deactivated through time stamping rules. Upon evaluating of the time stamping rules, the RED module shall set the TimeStampingFlag value in the requests to TRUE or FALSE according to the evaluation. Depending on the TimeStampingFlag value in the requests,modules shall either time stamp the ReceivedTime and SendingTime or exclude those elements in the corresponding response.
The RED module shall send the time stamping measurements by responding to the Time_ stamp_ Notification.
The RED module is able to measure following time.
1) transaction processing time
2) request processing time.
When the Time stamping function of each module is activated, the RED module shall measure the fllowing time.
3) module processing time.
The RED module shall measure the transaction processing time by calculating the difference between the time that the RED module received Transaction_ start_ request and the time that Final_ Result_ Notification is sent.
The RED module shall measure the request processing time by recording the sending time of the request and the received time of the response, and calculating the difference between them.
Processing_ response, Store_ response and Retrieve_ response have the information about the received time of the corresponding request and the sending time of the response itself as long as the Time stamping function is activated. By using them, the RED module is able to measure the module processing time. For example, the module processing time of the Processing module for one request from the RED module is measured by the difference between RecievedTime and SendingTime in the corresponding Processing_ response.
