[0049] Please refer to figure 1 , figure 1 A schematic diagram of a PTP slave device, a core network and an Internet network. The core network 12 connects the PTP slave device 11 and the Internet 13 . The PTP slave device 11 is, for example, a Femtocell or a Passive Optical Network (PON) device. The core network 12 includes a Security Gateway (SeGW) 121 , a PTP server 122 and a Packet Data Node Gateway (PGW) 123 . The PTP slave device 11 and the PTP server 122 are connected to the security gateway 121 , and the PTP server 122 and the security gateway 121 are connected to the Internet 13 via the packet network gateway 123 . Please note that any "connection" mentioned herein may be a direct or indirect connection.

[0059] Please also refer to figure 2 and Figure 4 , Figure 4 A flowchart of a method for performing network bandwidth measurement for a precision time protocol server. First, as shown in step 41 , the PTP server 122 exchanges messages with the PTP slave device 11 following the PTP. Step 41 is to assist the PTP slave device 11 to adjust the time of its slave clock Cs, and the PTP server 122 itself does not need to adjust the time of its master clock Cm through step 41 . Next, as shown in step 42 , the PTP server 122 calculates the network bandwidth according to the time information and size information related to the message.

[0060] The PTP server 122 can notify the PTP slave device 11 to adjust its transmission power according to the network bandwidth. For example, the downlink bandwidth between the PTP server 122 and the PTP slave device 11 is 4M. When the mobile phone 14a, mobile phone 14b, mobile phone 14c and mobile phone 14d have been connected to the Internet b...

Abstract

A method for measuring network bandwidth includes the following steps. The PTP slave follows the PTP, exchanging messages with the PTP server. The PTP slave device synchronizes the slave clock with the master clock of the PTP server based on the time information associated with the message. The PTP slave device calculates at least one network bandwidth according to time information and size information related to the message.

Description

technical field [0001] The invention relates to a measurement method, and in particular to a network bandwidth measurement method. Background technique [0002] The quality of network service is closely related to network bandwidth. There are several traditional network bandwidth measurement methods. For example, a network bandwidth measurement method is to set up a file transfer protocol (File Transfer Protocol, FTP) server to transmit data to calculate the network bandwidth. However, most traditional network bandwidth measurement methods generate unnecessary extra traffic and occupy valuable network bandwidth. Therefore, how to measure network bandwidth without generating extra traffic and adding additional servers has become a very important subject. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for measuring network bandwidth to solve the above-mentioned problems in the prior art. [0004] In o...
