[0022] For faults such as data congestion, insufficient bandwidth, and degraded service quality, manual troubleshooting is currently the most common method. This is usually only performed after the user's warranty is completed, making it impossible to implement regular monitoring. As a result, due to the large number of time-consuming and labor-intensive steps such as work order processing and manual troubleshooting, the network's operational efficiency is reduced.

[0023] The embodiments of the present application monitor network data forwarded by an optical line terminal (OLT) and implement network quality evaluation based on the network data forwarded by the OLT, thereby achieving automatic fault detection. Although the embodiments of the present application are proposed to solve the problems existing in PON, the network quality evaluation method of the embodiments of the present application does not exclude the possibility of implementing network quality evaluation based on other network devices, as long as network quality evaluation is required.

Figure 1 As shown in the figure, OLT is connected to the Broadband Remote Access Server (BRAS) and the Optical Network Unit (ONU). For OLT, BRAS is the network side and ONU is the user side. Figure 1 It only provides a schematic diagram of a currently achievable network architecture. With the development of technology, for other network architectures, the network side and the user side can also be other devices. This application does not limit the specific network architecture.

[0026] First, refer to Figure 2 An embodiment of the present application provides a network quality evaluation method, comprising:

[0027] Step 200: Acquire network transmission characteristic parameters.

[0028] In some exemplary embodiments, the network transmission characteristic parameter includes at least one of the following:

[0034] obtaining a second transmission characteristic parameter;

[0036] In some exemplary embodiments, the first transmission characteristic parameter on the network side refers to a transmission characteristic parameter of a data packet on the network side, that is, a characteristic parameter that can reflect the transmission process of the data packet on the network side.

[0037] In some exemplary embodiments, the data packet on the network side may be a data packet received from the network side, or a data packet sent to the network side, or a data packet received from the network side and a data packet sent to the network side.

[0038] In some exemplary embodiments, the first transmission characteristic parameter on the user side refers to a transmission characteristic parameter of a data packet on the user side, that is, a characteristic parameter that can reflect the transmission process of the data packet on the user side.

[0039] In some exemplary embodiments, the data packet on the user side may be a data packet received from the user side, or a data packet sent to the user side, or a data packet received from the user side and a data packet sent to the user side.

[0040] In some exemplary embodiments, the first transmission characteristic parameter on the network side or the first transmission characteristic parameter on the user side includes at least one of the following:

[0041] The minimum relative jitter value of the target service, the maximum relative jitter value of the target service, the average relative jitter value of the target service, the uplink network rate value of the target service, the downlink network rate value of the target service, the data rate value of the uplink target type of the target service, and the data rate value of the downlink target type of the target service; wherein the target type is the type of communication protocol used for communication between the user side and the network side.

[0042] In some exemplary embodiments, the target service may be any service requiring network quality evaluation, such as Internet Protocol Television (IPTV) service, Voice over Internet Protocol (VOIP) service, and the like.

[0043] In some exemplary embodiments, the target type may be, for example, a Transmission Control Protocol (TCP) type or a User Datagram Protocol (UDP) type. Of course, it may also be other communication protocol types, which is not limited in the embodiments of the present application.

[0044] Of course, the first transmission characteristic parameter may also be other parameters, and the embodiment of the present application does not limit the specific parameter form.

[0045] The following describes how to obtain each of the above first transmission characteristic parameters.

[0046] (1) Minimum relative jitter value of target service

[0047] In some exemplary embodiments, the first transmission characteristic parameter includes: a minimum relative jitter value of the target service; and obtaining the first transmission characteristic parameter on the network side and the first transmission characteristic parameter on the user side respectively includes:

[0048] Relative jitter values ​​of n pairs of data packets of the target service on the network side and relative jitter values ​​of n pairs of data packets of the target service on the user side are obtained respectively; wherein n is an integer greater than or equal to 1; the minimum relative jitter value of the target service on the network side is calculated based on the relative jitter values ​​of n pairs of data packets of the target service on the network side; the minimum relative jitter value of the target service on the user side is calculated based on the relative jitter values ​​of n pairs of data packets of the target service on the user side.

[0049] In some exemplary embodiments, each pair of data packets of the target service on the network side may refer to two adjacent data packets of the target service received and sent by the network side. For example, the i-th pair of data packets of the target service on the network side includes: the i-th data packet of the target service received and sent by the network side (another data packet described below) and the (i+1)-th data packet of the target service sent by the network side (one of the data packets described below).

[0050] In some exemplary embodiments, each pair of data packets of the target service on the user side may refer to two adjacent data packets sent to the target service on the user side. For example, the i-th pair of data packets of the target service on the user side includes: the i-th data packet sent to the target service on the user side (another data packet described below) and the (i+1)-th data packet sent to the user side (one of the data packets described below).

[0051] Of course, each pair of data packets for the target service on the network side can also be two non-adjacent data packets of the target service sent by the network side, and each pair of data packets for the target service on the user side can also be two non-adjacent data packets of the target service sent to the user side. However, it should be noted that for the same pair of data packets of the target service, the relative jitter value corresponding to the network side and the relative jitter value corresponding to the user side should be calculated separately. In other words, although each pair of data packets can be a random combination of any two data packets, once the combination is determined, the relative jitter value corresponding to the network side and the relative jitter value corresponding to the pair of data packets should be calculated separately to enable comparison of the relative jitter values ​​on the network side and the user side.

[0052] In some exemplary embodiments, the i-th data packet of the target service sent by the network side is defined as P w，i , the time for the network side to send the i-th data packet of the target service is T w，i The time when the current device (executing entity, such as OLT) receives the i-th data packet of the target service sent by the network side is T' w，i , the (i+1)th data packet of the target service sent by the network side is P w，i+1 , the time for the network side to send the (i+1)th data packet of the target service is T w，i+1 The time when the current device (executing entity, such as OLT) receives the (i+1)th data packet of the target service sent by the network side is T' w，i+1 .

[0053] According to the definition of delay time, the i-th data packet P of the target service w，i The delay time is L w，i =T' w，i -T w，i ; The (i+1)th data packet P of the target service w，i+1 The delay time is L w，i+1 =T' w，i+1 -T w，i+1 ;

[0054] According to the definition of jitter value, the i-th data packet P of the target service on the network side w，i and the (i+1)th data packet P of the target service on the network side w，i+1 The jitter value is:

[0055] J w，i =L w，i+1 -L w，i =T' w，i+1 -T' w，i -(T w，i+1 -T w，i );

[0056] Among them, Jw，i is the i-th data packet P of the target service on the network side w，i and the (i+1)th data packet P of the target service w， i +1 The jitter value, T w，i+1 T is the time when the network sends the (i+1)th data packet of the target service. w，i The time for the network side to send the i-th data packet of the target service, T' w，i+1 T' is the time when the (i+1)th data packet of the target service sent by the network is received. w，i The time when the i-th data packet of the target service sent by the network side is received.

[0057] Among them, since the packet capture tool captures the data packet when the current device receives the data packet, the difference between the time when the packet capture tool captures the data packet and the time when the current device receives the data packet can be ignored, so T' w，i+1 The time of receiving the (i+1)th data packet of the target service can be determined by using the packet capture tool, T' w，i The time of receiving the i-th data packet of the target service can be determined by using a packet capture tool.

[0058] And T w，i+1 and T w，i It is impossible to know, so the relative jitter value of the i-th pair of data packets of the target service on the network side can be defined as J w，i +T w，i+1 -T w，i ;

[0059] Similarly, according to the definition of jitter value, the i-th data packet P of the target service on the user side u，i and the (i+1)th data packet P of the target service on the user side u，i+1 The jitter value is:

[0060] J u，i =L u，n+1 -L u，n =T' u，i+1 -T' u，i -(T u，i+1 -T u，i );

[0061] Among them, J u，i is the i-th data packet P of the target service on the user side u，i and the (i+1)th data packet P of the target service u，i+1 The jitter value, T u，i+1 is the time for sending the (i+1)th data packet of the target service to the user side, T u，i is the time to send the i-th data packet to the user side, T'u，i+1 T' is the time when the user side receives the (i+1)th data packet of the target service. u，i The time when the user side receives the i-th data packet of the target service.

[0062] Among them, since the packet capture tool captures the data packet when the current device sends the data packet, the difference between the time when the packet capture tool captures the data packet and the time when the current device sends the data packet can be ignored. Therefore, T u，i+1 The time of sending the (i+1)th data packet of the target service can be determined by using a packet capture tool, T u，i The time of sending the i-th data packet of the target service can be determined by using a packet capture tool.

[0063] And T' u , i+1 and T' u , i cannot be known, so the relative jitter value of the i-th pair of data packets of the target service on the user side can be defined as T' u，i+1 -T' u，i -J u，i ;

[0064] Therefore, respectively obtaining the relative jitter values ​​of n pairs of data packets of the target service on the network side and the relative jitter values ​​of n pairs of data packets of the target service on the user side includes:

[0065] Calculating a relative jitter value of an i-th pair of data packets of the target service on the network side according to a time when one of the i-th pair of data packets of the target service sent by the network side is received and a time when the other of the i-th pair of data packets of the target service sent by the network side is received; wherein i is an integer greater than or equal to 1 and less than or equal to n;

[0066] The relative jitter value of the i-th pair of data packets of the target service on the user side is calculated based on the time of one of the i-th pair of data packets of the target service on the user side and the time of the other data packet of the i-th pair of data packets of the target service on the user side.

[0067] For example, according to formula J w，i +T w，i+1 -T w，i =T' w，i+1 -T' w，i Calculate the relative jitter value of the i-th pair of data packets of the target service on the network side, J w，i +T w，i+1 -T w，i is the relative jitter value of the i-th pair of data packets of the target service on the network side, J w，iis the jitter value of the i-th pair of data packets of the target service on the network side, T w，i+1 T is the time when the network sends one of the i-th pair of data packets of the target service. w，i The time when the network side sends another data packet of the i-th pair of data packets of the target service, T' w，i+1 T' is the time when one of the i-th pair of data packets of the target service sent by the network side is received. w，i The time when the other data packet of the i-th pair of data packets of the target service sent by the network side is received; i is an integer greater than or equal to 1 and less than or equal to n;

[0068] According to the formula T' u，i+1 -T' u，i -J u，i =T u，i+1 -T u，i Calculate the relative jitter value of the i-th pair of data packets of the target service on the user side, T' u，i+1 -T' u，i -J u，i is the relative jitter value of the i-th pair of data packets of the target service on the user side, J u，i is the jitter value of the i-th pair of data packets of the target service on the user side, T u，i+1 is the time when one of the i-th pair of data packets of the target service is sent to the user side, T u，i is the time when another data packet of the i-th pair of data packets of the target service on the user side is sent, T' u，i+1 The time when the user side receives one of the i-th pair of data packets of the target service, T' u，i The time when the user side receives the other data packet of the i-th pair of data packets of the target service.

[0117] The absolute value of the difference between the second transmission characteristic parameter and the bandwidth allocated by the operator is less than the second preset threshold value includes: the absolute value of the difference between the total downlink network rate value and the bandwidth allocated by the operator is less than the second preset threshold value.

[0118] In some exemplary embodiments, if the second transmission characteristic parameter includes: an uplink network total rate value and a downlink network total rate value, the absolute value of the difference between the second transmission characteristic parameter and the operator allocated bandwidth is greater than or equal to the second preset threshold value includes: the absolute value of the difference between the uplink network total rate value and the operator allocated bandwidth is greater than or equal to the second preset threshold value, and the absolute value of the difference between the downlink network total rate value and the operator allocated bandwidth is greater than or equal to the second preset threshold value;

[0120] In some exemplary embodiments, if the network transmission characteristic parameter includes: a second transmission characteristic parameter and a third transmission characteristic parameter;

[0121] Determining whether a forwarding failure occurs based on whether the bandwidth on the user side is fully occupied and network transmission characteristic parameters includes at least one of the following:

[0122] If the bandwidth on the user side is fully occupied and the absolute value of the difference between the second transmission characteristic parameter and the bandwidth allocated by the operator is greater than or equal to the second preset threshold, it is determined that a forwarding failure has occurred, which is defined as a second type of forwarding failure;

[0123] If the bandwidth on the user side is fully occupied and the absolute value of the difference between the second transmission characteristic parameter and the bandwidth allocated by the operator is less than the second preset threshold, it is determined that no forwarding failure occurs;

[0124] If the user side has fully occupied the bandwidth, and the absolute value of the difference between the second transmission characteristic parameter and the bandwidth allocated by the operator is less than the second preset threshold, and the absolute value of the difference between the second transmission characteristic parameter and the third transmission characteristic parameter is greater than or equal to the third preset threshold, it is determined that a forwarding failure has occurred, which is defined as a third type of forwarding failure;

[0126] The reason for comparing the second transmission characteristic parameter with the third transmission characteristic parameter to evaluate network quality is (the following uses the TCP data rate value as an example, and other communication protocol types are similar):

[0127] According to the characteristics of TCP data transmission, after the server sends a data packet, it will continue to send data packets only after the client sends an acknowledgment character (ACK, ACKnowledgement) message. If the client fails to upload the ACK message in time, the server will stop sending data packets and try to re-establish the connection with the client, resulting in a poor user experience. Therefore, in user usage scenarios where TCP data is the main traffic, if the total network rate value and the TCP data rate value differ significantly (that is, the absolute value of the difference between the second transmission characteristic parameter and the third transmission characteristic parameter is greater than or equal to the third preset threshold), it indicates that the current device has a forwarding failure.

[0130] In some exemplary embodiments, if the second transmission characteristic parameter includes: a total downlink network rate value, and the third transmission characteristic parameter includes: a total downlink target type data rate value, the absolute value of the difference between the second transmission characteristic parameter and the third transmission characteristic parameter being greater than or equal to a third preset threshold value includes: the absolute value of the difference between the total downlink network rate value and the total downlink target type data rate value being greater than or equal to the third preset threshold value;

[0131] The absolute value of the difference between the second transmission characteristic parameter and the third transmission characteristic parameter being less than the third preset threshold includes: the absolute value of the difference between the total downlink network rate value and the total downlink target type data rate value being less than the third preset threshold.

[0132] In some exemplary embodiments, if the second transmission characteristic parameter includes: an uplink network total rate value and a downlink network total rate value, and the third transmission characteristic parameter includes: an uplink target type data total rate value and a downlink target type data total rate value, the absolute value of the difference between the second transmission characteristic parameter and the third transmission characteristic parameter being greater than or equal to a third preset threshold value includes: the absolute value of the difference between the uplink network total rate value and the uplink target type data total rate value being greater than or equal to the third preset threshold value, and the absolute value of the difference between the downlink network total rate value and the downlink target type data total rate value being greater than or equal to the third preset threshold value;

[0133] The absolute value of the difference between the second transmission characteristic parameter and the third transmission characteristic parameter is less than the third preset threshold, which includes: the absolute value of the difference between the total uplink network rate value and the total data rate value of the uplink target type is less than the third preset threshold, and the absolute value of the difference between the total downlink network rate value and the total data rate value of the downlink target type is less than the third preset threshold.

[0137] If a forwarding failure is confirmed, network optimization is required;

[0142] If a forwarding failure is confirmed and the network optimization switch is on, network optimization is required.

[0143] If it is determined that no forwarding failure occurs, or the network optimization switch is off, it is determined that network optimization is not necessary.

[0166] The specific implementation process of the network quality evaluation method of the embodiment of the present application is described in detail below through a specific example. The examples listed are only for convenience of explanation and are not used to limit the scope of protection of the embodiment of the present application.

[0167] Example

[0168] like Figure 3 As shown, the method includes:

[0169] Step 300: Receive user input parameters; wherein, the user input parameters include: turning on the network optimization switch, the first preset threshold corresponding to the minimum relative jitter value of the target service, the first preset threshold corresponding to the maximum relative jitter value of the target service, the first preset threshold corresponding to the average relative jitter value of the target service, the network optimization number threshold and other internal parameters.

[0170] Step 301: Set the state of the network optimization switch to on.

[0171] Step 302: Use a packet capture tool to simultaneously start capturing the data packets of the target service sent by the network side and the data packets of the target service sent to the user side. After waiting for a period of time, stop capturing the data packets of the target service sent by the network side and the data packets of the target service sent to the user side.

[0172] Step 303: Calculate the minimum relative jitter value, maximum relative jitter value, and average relative jitter value of the target service on the network side based on the data packets of the target service sent by the network side that are captured within a period of time; calculate the minimum relative jitter value, maximum relative jitter value, and average relative jitter value of the target service on the user side based on the data packets of the target service sent to the user side that are captured within a period of time.

[0173] Step 304: When the bandwidth is not fully occupied on the user side and the first transmission characteristic parameter on the network side and the first transmission characteristic parameter on the user side meet the target conditions, it is determined that a forwarding failure has occurred, and step 305 is continued; when the bandwidth is not fully occupied on the user side and the first transmission characteristic parameter on the network side and the first transmission characteristic parameter on the user side do not meet the target conditions, it is determined that no forwarding failure has occurred, and this process is ended.

[0174] In this step, the target conditions include: the absolute value of the difference between the minimum relative jitter value of the target service on the network side and the minimum relative jitter value of the target service on the user side is greater than or equal to the first preset threshold corresponding to the minimum relative jitter value of the target service, or the absolute value of the difference between the maximum relative jitter value of the target service on the network side and the maximum relative jitter value of the target service on the user side is greater than or equal to the first preset threshold corresponding to the maximum relative jitter value of the target service, or the absolute value of the difference between the average relative jitter value of the target service on the network side and the average relative jitter value of the target service on the user side is greater than or equal to the first preset threshold corresponding to the average relative jitter value of the target service.

[0175] Step 305: Obtain the parameters configured in the downstream bandwidth template and the parameters configured in the downstream QoS template for the target service flow channel. Taking GPON as an example, the parameters configured in the downstream bandwidth template that need to be obtained include: downstream maximum bandwidth; the parameters configured in the QoS template that need to be obtained include: downstream token bucket injection rate and downstream token bucket depth.

[0176] Step 306: Since the current state of the network optimization switch is on, adjust the parameters configured in the QoS template, namely, the downstream token bucket injection rate and the downstream token bucket depth.

[0177] Step 307: add 1 to the current number of network optimizations. If the current number of network optimizations is less than or equal to the network optimization threshold, return to step 302 to continue execution. If the current number of network optimizations is greater than the network optimization threshold, end this process.
