Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a diagram of an application environment of a bandwidth measurement method in one embodiment. The bandwidth measuring method is applied to a bandwidth measuring system. The bandwidth measurement system includes a computer device 110, a target network device 120, and a user terminal 130. The computer device 110, the target network device 120 and the user terminal 130 are connected through a network. The network may be implemented by the computer device 110 as a stand-alone server or as a server cluster comprising a plurality of servers. The computer device 110 may be, for example, a CDN (Content Delivery Network) server, another server, or a terminal. The target network device 120 may be a network device corresponding to the object identifier to be detected, for example, a switch, a server, a routing device, a gateway, or an infinite access point corresponding to the object identifier to be detected. The user terminal 130 may be a desktop terminal or a mobile terminal, and the mobile terminal may be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The number of the computer devices 110, the target network devices 120 and the user terminals 130 is not limited. The bandwidth measurement procedure may be applied to the computer device 110.
In one embodiment, as shown in FIG. 2, a bandwidth measurement method is provided. The embodiment is mainly illustrated by applying the method to the computer device 110 in fig. 1. Referring to fig. 2, the bandwidth measurement method specifically includes the following steps:
The object to be detected may be an operator or an enterprise. Such as mobile, internet, telecommunication or radio, etc. The object to be detected may particularly also distinguish nationalities, for example, china, usa or europe. The object identification to be detected is a unique identification used for distinguishing the object to be detected. The object identifier to be detected may specifically be composed of at least one of characters, numbers or symbols. The Internet Protocol Address refers to an IP Address (Internet Protocol Address) used for marking a computer in a network. The number of internet protocol addresses is not limited, and may be any number of internet protocol addresses.
Specifically, when the bandwidth measurement program receives a bandwidth measurement instruction, a large number of internet protocol addresses corresponding to the object identifier to be detected are acquired from a service access log stored in the server or from an internet protocol address database. For example, the bandwidth measurement program acquires a large number of internet protocol addresses corresponding to the mobile operator.
And 204, sending a User Datagram Protocol (UDP) message to a user terminal corresponding to the Internet protocol address at an adjustable broadband rate, wherein the UDP message corresponding to the adjustable broadband rate is used for causing network congestion to occur to a link between target network equipment corresponding to the object identifier to be detected.
The adjustable broadband rate means that the broadband rate is variable, for example, the broadband rate may be a broadband rate preset in the server, such as 5GB/s (Gigabyte per second), 6GB/s, and the like, but is not limited thereto. The broadband rate may specifically also be adjusted according to network congestion conditions. The wideband rate may specifically be presented in the form of a value of the wideband rate or in a hierarchical manner. For example, the primary wideband rate may correspond to 5GB/s, the secondary wideband rate may correspond to 6GB/s, etc. without limitation. The UDP packet may include a header and any packet data. After the UDP packet is sent, the server corresponding to the bandwidth measurement program cannot know whether the UDP packet arrives safely and completely. The size of the message data may be set according to the bandwidth or broadband rate between the target network device and the user. Network congestion is an overloaded network condition. The demand of user terminals on network resources, such as link bandwidth, during network congestion exceeds the inherent bandwidth capacity.
Specifically, the bandwidth measurement program establishes a network connection with the target network device and the user terminal corresponding to the internet protocol address. When the bandwidth measurement program is located in a server, the bandwidth measurement program serially sends a UDP message to a user terminal corresponding to an Internet protocol address through the target network device at a first broadband speed. The bandwidth measurement program may also send UDP packets serially to the user terminal corresponding to the internet protocol address at, but not limited to, the second broadband rate, the third broadband rate, etc. And sending the UDP message at least once correspondingly at each broadband rate. The UDP packet corresponding to the adjustable broadband rate may be used to cause a link between the server and the target network device corresponding to the object identifier to be detected to generate network congestion. The UDP packet corresponding to the adjustable broadband rate may also be used to enable a link between the server and the target network device corresponding to the object identifier to be detected to be in a network available state.
In this embodiment, the adjustment method of the broadband rate includes: and the broadband rate is adjusted by controlling the sending frequency of the UDP message. Specifically, the bandwidth measurement procedure increases the broadband rate by increasing the transmission frequency of UDP packets. Alternatively, the bandwidth measurement procedure reduces the broadband rate by reducing the transmission frequency of UDP packets. For example, the bandwidth measurement program may control the sending frequency of the UDP packet to be one thousand times per second, that is, 0.001GB/ms, and then the broadband rate is 1 GB/s. The bandwidth measurement program can increase the sending frequency of the UDP message to be two thousand times per second, that is, 0.002GB/s, and then the broadband rate is 2 GB/s.
In this embodiment, the adjustment method of the broadband rate includes: and the broadband rate is adjusted by controlling the message data size in the UDP message. Specifically, the bandwidth measurement procedure increases the broadband rate by increasing the packet data size in the UDP packet. Or the bandwidth measurement procedure reduces the broadband rate by reducing the message data size in the UDP message. For example, the bandwidth measurement program may set the size of the UDP packet to 4M, and then 256 UDP packets with the size of 4M are sent within 1 second, so that the broadband rate is 1 GB/s. The bandwidth measurement program can set the size of the UDP message to be 8M, and then 256 UDP messages with the size of 8M are sent within 1 second, so that the broadband rate can be 2 GB/s.
In this embodiment, when each of the plurality of servers runs the bandwidth measuring program, the bandwidth measuring program in the plurality of servers concurrently sends the UDP packet to the terminal corresponding to the internet protocol address.
Specifically, when it is detected that the link between the server and the target network device changes from the network available state to the network congestion state through a packet loss condition or a delay condition, the bandwidth measurement program acquires the maximum broadband rate corresponding to the link in the available state. Or, when detecting that the link between the server and the target network device changes from the network congestion state to the network available state through a packet loss condition or a delay condition, the bandwidth measurement program acquires the maximum broadband rate corresponding to the link in the available state. The packet loss condition refers to the packet loss rate or the corresponding packet loss number when the total number of the transmitted data packets is the same, and the like. For example, 1000 data packets are fixedly sent, and 900 data packets are returned, the number of packet loss is 100, and the packet loss rate is 10%, and the bandwidth measurement program can obtain the packet loss condition through the number of received data packets or the packet loss rate.
And step 208, processing according to the corresponding maximum broadband rate when the link is in the network available state to obtain the maximum available bandwidth of the link with the target network device.
The maximum available bandwidth refers to the maximum amount of data that can pass through the link per unit time.
Specifically, the bandwidth measurement program processes the maximum bandwidth rate corresponding to the link in the network available state according to the conversion relationship between the bandwidth rate and the bandwidth to obtain the maximum available bandwidth of the link before the target network device. For example, a wideband rate of 256KB/s corresponds to a bandwidth of 2M/s.
According to the bandwidth measuring method, the internet protocol address corresponding to the to-be-detected object identifier is obtained, the UDP message is sent to the terminal corresponding to the internet protocol address at an adjustable broadband speed, and the UDP message is a connectionless-oriented protocol and has the characteristics of low resource consumption and high processing speed, so that network equipment does not need to be deployed in advance, the user terminals do not need to be kept in an online state for interaction, and all the user terminals do not need to receive the UDP message, and the bandwidth measuring method is low in cost, high in operability and good in universality; when the link is detected to change from the first network state to the second network state, the maximum broadband rate corresponding to the available state is obtained, the maximum available bandwidth is obtained through processing, the process of using the flow of the user terminal in the actual situation can be simulated, the measurement scene is close to the actual usage scene, and the accuracy of bandwidth measurement is improved.
In one embodiment, when each server in the plurality of servers runs the bandwidth measurement program, and the target network devices corresponding to one object identifier to be detected are multiple, the bandwidth measurement program adds the maximum available bandwidth of the link measured by each server for each target network device to obtain the maximum available bandwidth of the link between all the servers and all the target network devices. The bandwidth measuring method can be applied to the condition that a plurality of links are arranged between the server and the target network equipment, and has high operability and simple calculation.
In one embodiment, the detection method of the congestion status includes: acquiring the packet loss rate of a link; and when the packet loss rate of the link is greater than the packet loss rate threshold, determining that the link is in a network congestion state.
The packet loss rate is a ratio of the number of lost packets to the number of transmitted packets. The data packet may specifically be an ICMP (Internet Control Message Protocol) packet or a TCP (Transmission Control Protocol) packet. The specific expression of the packet loss rate can be percentage, decimal, fraction, or the like. The packet loss rate threshold may refer to an upper limit value of packet loss.
Specifically, the bandwidth measurement program may obtain the packet loss rate of the link through the ping command. The Ping command refers to a command under the Windows, Unix or Linux system. ping also belongs to a communication protocol, and it is possible to check whether the network is connected or not by using a "ping" command. And when the packet loss rate of the link is detected to be greater than the packet loss rate threshold value, determining that the link is in a network congestion state by the bandwidth measurement program. For example, if the packet loss rate threshold is 5%, when the packet loss rate of the link is greater than 5%, the bandwidth measurement program determines that the link is in a network congestion state.
In this embodiment, when the packet loss rate of the link is less than or equal to the packet loss rate threshold, it is determined that the link is in a network available state. For example, if the packet loss rate threshold is 5%, the bandwidth measurement procedure determines that the link is in a network available state when the packet loss rate of the link is less than or equal to 5%.
According to the bandwidth measurement method, the packet loss rate of the link is obtained, when the packet loss rate of the link is greater than the packet loss rate threshold, the link is determined to be in the congestion state, whether the network is in the congestion state or not can be checked, the packet loss rate error caused by reasons except network congestion can be avoided to a certain extent through the packet loss rate threshold, and the accuracy of bandwidth measurement is improved.
In an embodiment, as shown in fig. 3, obtaining a packet loss rate of a link includes:
Wherein, one object identifier to be detected can correspond to a plurality of target network devices. The ICMP packet is mainly used for transmitting control information, including packet loss rate, between the ue and the network device. The ICMP message includes an IP address and an ICMP header corresponding to the target network device. The number of ICMP messages is not limited.
Specifically, the bandwidth measurement program obtains an IP address corresponding to the target network device. When the bandwidth measuring program sends the UDP message to the user terminal corresponding to the Internet protocol address at an adjustable broadband speed, the predetermined number of ICMP messages are also sent to at least one target network device through the Ping command and the IP address.
Specifically, after receiving the ICMP message sent by the bandwidth measurement program, the target network device returns an ICMP echo message to the target network device. And the bandwidth measuring program receives an ICMP echo message returned by the target network equipment.
Specifically, the bandwidth measurement program acquires the number of ICMP messages sent. And the bandwidth measuring program counts the quantity of ICMP echo messages returned by the target network equipment. And the bandwidth measuring program determines the packet loss rate of a link between the server and the target network equipment according to the number of the sent ICMP messages and the number of the returned ICMP messages. The calculation method may specifically be that the packet loss rate is (the number of ICMP messages to be sent-the number of ICMP messages to be returned)/the number of ICMP messages to be sent × 100%.
The bandwidth measuring method transmits the ICMP message to at least one target network device in the target network devices, receives the ICMP response message returned by the target network devices, determines the packet loss rate according to the number of the transmitted messages and the response message, and can detect the network state only by transmitting the ICMP message to at least one target network device, thereby having strong operability and low cost.
In an embodiment, as shown in fig. 4, obtaining a packet loss rate of a link includes:
The ue capable of responding ICMP message also refers to a ue capable of responding ping command.
Specifically, before the internet protocol address corresponding to the object identifier to be detected is acquired, or after the internet protocol address corresponding to the object identifier to be detected is acquired, the bandwidth measurement program may send an ICMP message to the user terminal corresponding to the IP address corresponding to the object identifier to be detected through the Ping instruction. The user terminal receives ICMP message and returns ICMP echo message to the bandwidth measuring program. The bandwidth measurement program determines that the IP address is a live (alive) IP address. When the user terminal corresponding to the IP address cannot return the ICMP response message to the server, the bandwidth measurement program determines that the IP address is not a live IP address, so that the bandwidth measurement program cannot send the ICMP message to the user terminal corresponding to the IP address which cannot return the ICMP response message when detecting the network state.
And when the bandwidth measurement program receives the ICMP response message, selecting at least one user terminal capable of responding the ICMP message as a target user terminal.
Specifically, when the bandwidth measurement program sends a UDP message to a user terminal corresponding to an internet protocol address at an adjustable broadband rate, an ICMP message is also sent to at least one target user terminal through the target network device.
Specifically, after receiving the ICMP message sent by the bandwidth measurement program, the target user terminal returns an ICMP echo message to the server where the bandwidth measurement program is located. And the bandwidth measuring program receives an ICMP response message returned by the target user terminal.
Specifically, the bandwidth measurement program acquires the number of ICMP messages sent. And the bandwidth measuring program counts the quantity of ICMP echo messages returned by the target user terminal. And the bandwidth measuring program determines the packet loss rate of a link between the server and the target network equipment according to the number of the sent ICMP messages and the number of the returned ICMP messages. The calculation method may specifically be that the packet loss rate is (the number of ICMP messages to be sent-the number of ICMP messages to be returned)/the number of ICMP messages to be sent × 100%.
According to the bandwidth measuring method, at least one user terminal capable of responding ICMP messages is selected from user terminals corresponding to Internet protocol addresses as a target user terminal, the target terminal can be ensured to be in an alive (alive) state, the ICMP messages are sent to the online user terminal at least, the ICMP response messages returned by the target user terminal are received, the packet loss rate of a link between the user terminal and the target network equipment is determined according to the number of the sent ICMP messages and the number of the returned ICMP response messages, the packet loss rate of the link between the user terminal and the target network equipment can also be determined, the network state can be detected, and the method is strong in operability and low in cost.
In one embodiment, obtaining the packet loss rate of the link includes: receiving an ICMP message sent by a user terminal; sending an ICMP response message to the user terminal; and receiving a packet loss rate value returned by the user terminal, wherein the packet loss rate value is determined by the user terminal according to the number of the sent ICMP messages and the number of the ICMP echo messages.
Specifically, the user terminal sends an ICMP message to the server where the bandwidth measurement program is located through the Ping command. And the bandwidth measuring program receives an ICMP message sent by the user terminal. The bandwidth measuring program returns ICMP response message to the user terminal. And the user terminal obtains the value of the packet loss rate according to the number of the sent ICMP messages and the number of the received ICMP response messages. And the user terminal sends the value of the packet loss rate to a server where the bandwidth measuring program is located. And the bandwidth measuring program receives the value of the packet loss rate returned by the user terminal.
According to the bandwidth measuring method, the ICMP message sent by the user terminal is received, the ICMP response message is returned to the user terminal, and the value of the sent packet loss rate is received, so that not only can the packet loss rate of the link between the user terminal and the target network equipment be determined, but also the packet loss rate of the link between the user terminal and the target network equipment can be determined, the network state can be detected, and the bandwidth measuring method is high in operability and low in cost.
In one embodiment, the method for detecting the network status includes: acquiring delay time of a link; when the delay time of the link is greater than the delay time threshold, determining that the link is in a network congestion state; when the delay time of a link is less than or equal to a delay time threshold, the link is determined to be in a network available state.
Specifically, for example, if the delay time threshold is 100ms, when the delay time is greater than 100ms, it is determined that the link is in a network congestion state; and when the delay time is 0-100 ms, determining that the link is in a network available state.
According to the bandwidth measuring method, the delay time of the link is obtained, when the delay time is larger than the delay time threshold, the congestion state of the network is determined, when the delay time is smaller than the delay time threshold, the congestion state of the network is determined, the network state can be obtained according to the delay time detection, and therefore the bandwidth of the link is obtained.

According to the bandwidth measuring method, the packet loss rate and the delay time are detected simultaneously, the congestion state of the network can be judged more accurately, and the accuracy of bandwidth measurement is improved.
In one embodiment, obtaining the delay time of the link comprises: sending an ICMP message to at least one target network device in the target network devices or at least one target user terminal capable of responding the ICMP message, and acquiring corresponding sending time; when receiving ICMP response message returned by target network equipment or target user terminal, obtaining the receiving time of ICMP response message; and obtaining the delay time of the link according to the sending time and the receiving time.

And when receiving the ICMP response message returned by the target user terminal, acquiring the receiving time of the received ICMP response message. The bandwidth measurement procedure derives the delay time of the link from the transmission time and the reception time.
According to the bandwidth measuring method, the delay time of the link is obtained by obtaining the sending time and the receiving time, the phenomenon that the ICMP message data volume is large due to the fact that the time stamp is added into the ICMP message can be avoided, the ICMP message data volume is small, network congestion is not prone to increase, and the accuracy of bandwidth measurement is improved.
In one embodiment, sending a user datagram protocol UDP packet to a user terminal corresponding to an internet protocol address at an adjustable broadband rate, includes: sending User Datagram Protocol (UDP) messages to user terminals corresponding to Internet protocol addresses at the sequentially increased broadband rates; the first network state is a network available state; the second network state is a network congestion state.
Specifically, the bandwidth measurement program sends UDP packets to the user terminal corresponding to the internet protocol address at the successively increased bandwidth rate. For example, the bandwidth measuring program sends UDP messages to the user terminal corresponding to the Internet protocol address at the bandwidth rate of 1GB/s, 2GB/s, 3GB/s … … and the like. When detecting that a link between the server and the target network device changes from a network available state to a network congestion state, acquiring a broadband rate corresponding to the last time the link is in the network available state, namely acquiring a maximum broadband rate corresponding to the link in the network available state.

Specifically, the IP addresses may be stored in a list.
The initial wideband rate S may specifically be a predicted wideband rate value.
Specifically, the server may detect whether a packet loss occurs in a link between the server and the target network device through the congestion information. The congestion information includes at least one of a packet loss rate and a delay time.
And step 508, when no packet loss occurs in the link between the server and the target network device, increasing the broadband rate S.
Specifically, after the broadband rate S is increased, the obtained broadband rate is S +1, and then the server sends the UDP packet to any user terminal corresponding to the IP address in the IP address list at the broadband rate of S + 1.
And step 510, processing according to the broadband rate of the last non-packet loss to obtain the maximum available bandwidth.
Specifically, for example, when the broadband rate is S +5, and the bandwidth measurement program detects that a packet loss occurs in a link between the target network device and the bandwidth measurement program, the broadband rate S +4 at which the packet loss does not occur at the last time is obtained, and the maximum available bandwidth of the link is calculated according to the broadband rate S + 4.
In this embodiment, the principle of determining whether the maximum available bandwidth is reached through the congestion information is as follows: when the transmission rate of the data message on the link is less than the maximum available bandwidth of the network link, the transmitted message is not congested, the delay of the message is stable and no packet is lost; if the sending rate of a certain end is greater than the maximum available bandwidth of the network link, the link is congested, the delay time for transmitting a message on the link is increased, and the packet loss rate is increased, so that whether the current bandwidth of the link reaches the maximum available bandwidth or not can be judged according to congestion information such as the delay time, the packet loss rate and the like of the message.

Specifically, before the internet protocol address corresponding to the object identifier to be detected is acquired, the bandwidth measurement program imports the whole internet protocol address corresponding to the object identifier to be detected into the memory array and stores the whole internet protocol address. Each number corresponds to an internet protocol address. The bandwidth measurement program randomly generates a random number identification.
Specifically, the bandwidth measurement program acquires an internet protocol address corresponding to the random number identifier. For example, if the random number is 5 and the corresponding IP address is 123.123.1.1, the bandwidth measurement program obtains an IP address of 123.123.1.1.
Specifically, the bandwidth measurement program serially sends UDP packets to the user terminal corresponding to the IP address corresponding to the random number identifier at a sequentially increasing or sequentially decreasing bandwidth rate. For example, a server corresponding to the bandwidth measurement program generates a random number identifier, for example, 10, 8, 11, 19, 5 …, etc., but not limited thereto, when the broadband rate is 5GB/s, the bandwidth measurement program sends UDP packets to the user terminal corresponding to the IP address corresponding to 10, 8, 11, 19, 5 in serial at the broadband rate of 5 GB/s.

The bandwidth measurement programs all generate random number identifiers, acquire the IP addresses corresponding to the random number identifiers, and send UDP messages to the user terminals corresponding to the IP addresses corresponding to the random number identifiers, so that the condition that a plurality of machines send UDP messages to the same IP address at the same time can be avoided.
