Step 202, Internet protocol address corresponding with object identity to be detected is obtained.

Wherein, object to be detected specifically can be operator or enterprise etc..Operator such as movement, connection, telecommunications or Broadcasting and TV etc..Object to be detected specifically can also distinguish between nationality, such as distinguish China, the U.S. or Europe etc..Object mark to be detected Knowledge is the unique identification for distinguishing object to be detected.Object identity to be detected specifically can be by text, number or symbol At least one composition.Internet protocol address refers to IP address (Internet Protocol Address), in network One computer of middle label.The quantity of Internet protocol address is unlimited, is specifically as follows the Internet protocol address of arbitrarily large number.

Specifically, when bandwidth measurement program receives bandwidth measurement instruction, business access day for being stored from server In will, or from Internet protocol address database with obtaining a large amount of Internet protocol corresponding with object identity to be detected Location.For example, bandwidth measurement program obtains a large amount of Internet protocol address corresponding with mobile operator.

Step 204, user data is sent to the corresponding user terminal of Internet protocol address with adjustable broadband rate Datagram protocol UDP message, wherein the corresponding UDP message of adjustable broadband rate for make with corresponding to object identity to be detected Destination network device between link occur network congestion.

Wherein, adjustable broadband rate refers to broadband rate-compatible, such as broadband rate can be default in server Broadband rate 5GB/s (Gigabyte per second, hundred billion bytes-per-seconds), 6GB/s etc. it is without being limited thereto.Broadband rate tool Body can also be according to network congestion adjusting.Broadband rate specifically can be with the value of broadband rate, can also be with rank Mode is presented.Such as level-one broadband rate corresponds to 5GB/s, it is without being limited thereto that two-stage wideband rate corresponds to 6GB/s etc..In UDP message It may include header and arbitrary message data.After UDP message is sent, the corresponding server of bandwidth measurement program can not be obtained Know the whether safe and complete arrival of UDP message.The size of message data can according between destination network device and user bandwidth or The setting of person broadband rate.Network congestion is a kind of network state of overload.When network congestion user terminal to Internet resources for example The demand of link bandwidth has been more than intrinsic bandwidth capacity.

Specifically, bandwidth measurement program user terminal corresponding with destination network device and Internet protocol address is established Network connection.When bandwidth measurement program is located in a server, bandwidth measurement program passes through target with the first broadband rate The network equipment serially sends UDP message to the corresponding user terminal of Internet protocol address.Bandwidth measurement program can also be with Two broadband rates, third broadband rate etc. are without being limited thereto serially to send UDP to the corresponding user terminal of Internet protocol address Message.Wherein, each broadband rate is corresponding sends UDP message at least once.The corresponding UDP message of adjustable broadband rate Network congestion occurs for the link that can be used for making between server destination network device corresponding with object identity to be detected.It is adjustable The corresponding UDP message of broadband rate can also be used to make between server destination network device corresponding with object identity to be detected Link present network available status.

In the present embodiment, the regulative mode of broadband rate, comprising: the transmission frequency by controlling UDP message adjusts broadband Rate.Specifically, bandwidth measurement program passes through the transmission frequency for increasing UDP message, to increase broadband rate.Alternatively, bandwidth Process of measurement passes through the transmission frequency for reducing UDP message, to reduce broadband rate.Such as bandwidth measurement program can control The transmission frequency of UDP message sends 1,000 times, i.e. 0.001GB/ms to the corresponding user terminal of Internet protocol address to be per second, So broadband rate is 1GB/s.Bandwidth measurement program can increase UDP message transmission frequency be it is per second to Internet protocol The corresponding terminal in location sends 2,000 times, i.e. 0.002GB/s, then broadband rate is 2GB/s.
