Why Is the CAR or GTS Sometimes Incorrect?
The committed access rate (CAR) or generic traffic shaping (GTS) is set by the AR main control board or interface board based on traffic volume. If the CAR or GTS is set by the interface board, the accuracy depends on the granularity of the rate limit. Within a specified granularity range, all CAR or GTS values are correct. In addition, different bearer links may trigger the protocol encapsulation correction.
