Abstract

A method for measuring network throughput is provided. The method comprises the following steps: exchanging messages with a time synchronization protocol server in compliance with a time synchronization protocol, synchronizing a slave clock with a master clock of the time synchronization protocol server according to time information related to the messages, and calculating at least one network throughput according to the time information and size information related to the messages.

Claims

1. A method at a time synchronization protocol slave device, the method comprising:

exchanging a plurality of messages with a time synchronization protocol server in compliance with a time synchronization protocol;

synchronizing a slave clock with a master clock of the time synchronization protocol server according to time information related to the plurality of messages;

calculating at least one network throughput according to the time information and size information related to the plurality of messages; and

reducing a radio frequency transmission power when the at least one network throughput is insufficient.

2. The method according to claim 1, wherein the step of calculating the at least one network throughput according to the time information and the size information related to the plurality of messages comprises:

calculating a network downlink throughput according to time information and size information related to a plurality of received messages of the plurality of messages, wherein the plurality of received messages comprise at least 100 received messages.

3. The method according to claim 1, wherein the step of calculating the at least one network throughput according to the time information and the size information related to the plurality of messages comprises:

calculating a network uplink throughput according to time information and size information related to a plurality of transmitted messages of the plurality of messages, wherein the plurality of transmitted messages comprise at least 100 transmitted messages.

4. The method according to claim 1, wherein the method is executed by a femtocell or a passive optical network device.

5. The method according to claim 1, wherein the time synchronization protocol is Precision Time Protocol or Network Time Protocol.

6. A method at a time synchronization protocol server, the method comprising:

exchanging a plurality of messages with a time synchronization protocol slave device in compliance with a time synchronization protocol;

calculating at least one network throughput according to time information and size information related to the plurality of messages; and

informing the time synchronization protocol slave device to reduce a radio frequency transmission power of the time synchronization protocol slave device when the at least one network throughput is insufficient.

7. The method according to claim 6, wherein the step of calculating the at least one network throughput according to the time information and the size information related to the plurality of messages comprises:

calculating a network downlink throughput according to time information and size information related to a plurality of transmitted messages of the plurality of messages, wherein the plurality of transmitted messages comprise at least 100 transmitted messages.

8. The method according to claim 6, wherein the step of calculating the at least one network throughput according to the time information and the size information related to the plurality of messages comprises:

calculating a network uplink throughput according to time information and size information related to a plurality of received messages of the plurality of messages, wherein the plurality of received messages comprise at least 100 received messages.

9. The method according to claim 6, wherein the time synchronization protocol slave device is a femtocell or a passive optical network device.
