[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The traditional business recovery priority assessment method analyzes the loss impact of business interruption through financial impact assessment value and non-financial impact assessment value, and obtains the business recovery time objective (RTO) and recovery data point objective (RPO) according to the tolerable maximum interruption time and maximum data loss time of the business, and then determines the disaster recovery priority level of the business system, so as to formulate the disaster recovery strategy shown in Table 1. However, in the process of formulating business recovery priorities, the existing technology does not consider the impact of the service quality (Quality of Service, QoS) and the experience quality (Quality of Experience, QoE) of the business, such as latency, bandwidth, jitter, packet loss rate, etc., which affects the allocation of disaster recovery resources and the formulation of disaster recovery strategies, and ultimately causes the business after recovery to fail to meet the basic QoS and QoE requirements.

[0041] Table 1

[0042] Disaster recovery capability level RTO RPO 1 More than 2 days 1 day to 7 days 2 24 hours later 1 day to 7 days 3 More than 12 hours Several hours to 1 hour 4 A few hours to 2 days Several hours to 1 hour 5 A few minutes to 2 days 0 to 30 minutes 6 A few minutes 0

[0043] Based on the above problems, the present invention introduces business recovery QoS goals and business recovery QoE goals, and combines them with RTO, RPO and other goals to formulate more comprehensive and objective disaster recovery priorities, ensure the reasonable allocation of disaster recovery resources and the formulation of disaster recovery strategies, and maximize the QoS and QoE after business recovery.

[0044] Therefore, the present invention provides a method for evaluating business recovery priority. The execution subject of the method can be a business recovery priority evaluation device. The business recovery priority evaluation device can be implemented as part or all of a terminal device through software, hardware, or a combination of software and hardware. Optionally, the terminal device can be a personal computer (PC), a portable device, a laptop, a smart phone, a tablet computer, a portable wearable device, or other electronic devices, such as a tablet computer, a mobile phone, etc. The present invention does not limit the specific form of the terminal device.

[0045] It should be noted that the execution subject of the following method embodiment may be part or all of the above terminal device. The following method embodiment is described by taking the execution subject as the terminal device as an example.

[0046] Reference Figure 1 , is a flow chart of the service recovery priority evaluation method provided by the present invention, such as Figure 1 As shown, the business recovery priority assessment method includes the following steps:

[0047] Step 110: respectively obtain the RTO evaluation value, RPO evaluation value, tolerable minimum QoS evaluation value, and tolerable minimum QoE evaluation value of the target service.

[0048] Specifically, for the target service to be restored, the terminal device can first evaluate the loss impact caused to the target service over time after the interruption of the target service, and then further determine the RTO evaluation value, RPO evaluation value, tolerable minimum QoS evaluation value and tolerable minimum QoE evaluation value of the target service based on the loss impact.

[0049] It should be noted that when determining the tolerable minimum QoS evaluation value and the tolerable minimum QoE evaluation value of the target service, in addition to considering the impact of losses caused by the target service terminal over time, the latency, bandwidth, jitter, packet loss rate and image quality score of the target service are also considered. Therefore, the determined tolerable minimum QoS evaluation value and the tolerable minimum QoE evaluation value are more reliable and accurate.

[0050] Step 120: Determine the target recovery priority of the target service according to the RTO evaluation value, the RPO evaluation value, the tolerable minimum QoS evaluation value, and the tolerable minimum QoE evaluation value.

[0051] Specifically, when the terminal device obtains the RTO evaluation value, RPO evaluation value, tolerable minimum QoS evaluation value and tolerable minimum QoE evaluation value of the target service, it can further combine the RTO evaluation value, RPO evaluation value, tolerable minimum QoS evaluation value and tolerable minimum QoE evaluation value to determine the target recovery priority of the target service, thereby avoiding the defects of the existing method of formulating disaster recovery strategies based only on the two indicators of RTO and RPO, such as unreasonable allocation of disaster resources and low objectivity of disaster recovery strategies, thereby facilitating the formulation of a more comprehensive and objective disaster recovery strategy.

[0052] The service recovery priority evaluation method provided by the present invention first obtains the RTO evaluation value, RPO evaluation value, tolerable minimum QoS evaluation value and tolerable minimum QoE evaluation value of the target service respectively; then determines the target recovery priority of the target service according to the RTO evaluation value, the RPO evaluation value, the tolerable minimum QoS evaluation value and the tolerable minimum QoE evaluation value. That is, the present invention achieves the purpose of formulating disaster recovery priorities by introducing service recovery QoS targets and service recovery QoE targets, and combining the service recovery QoS targets and service recovery QoE targets with the RTO targets and RPO targets, thereby ensuring the reasonable allocation of disaster recovery resources and formulating a more objective and comprehensive disaster recovery strategy, and also maximizing the service quality and experience quality after service recovery.

[0053] Optionally, the specific execution process of step 120 includes:

[0054] First, respectively determine the RTO priority weight of the RTO evaluation value, the RPO priority weight of the RPO evaluation value, the QoS priority weight of the tolerable minimum QoS evaluation value, and the QoE priority weight of the tolerable minimum QoE evaluation value; then determine the target recovery priority of the target service based on the RTO evaluation value, the RTO priority weight, the RPO evaluation value, the RPO priority weight, the tolerable minimum QoS evaluation value, the QoS priority weight, the tolerable minimum QoE evaluation value, and the QoE priority weight.

[0055] Specifically, according to the different service types of the target service, the RTO priority weight of the RTO evaluation value, the RPO priority weight of the RPO evaluation value, the QoS priority weight of the tolerable minimum QoS evaluation value, and the QoE priority weight of the tolerable minimum QoE evaluation value can be pre-set. For example, when the target service is a transaction service, the RTO evaluation value and the RPO evaluation value can be set to have higher weights, that is, the RTO priority weight and the RPO priority weight are both larger than the QoS priority weight and the QoE priority weight; when the target service is a video service, the tolerable minimum QoS evaluation value and the tolerable minimum QoE evaluation value can be set to have higher weights, that is, when the target service is a video service, the QoS priority weight and the QoE priority weight are both larger than the RTO priority weight and the RPO priority weight. Then, based on the RTO evaluation value and its RTO priority weight, the RPO evaluation value and its RPO priority weight, the tolerable minimum QoS evaluation value and its QoS priority weight, and the tolerable minimum QoE evaluation value and its QoE priority weight, the target recovery priority of the target service is determined.

[0056] The service recovery priority evaluation method provided by the present invention achieves the purpose of determining the target recovery priority of the target service through the RTO evaluation value and its RTO priority weight, the RPO evaluation value and its RPO priority weight, the tolerable minimum QoS evaluation value and its QoS priority weight, and the tolerable minimum QoE evaluation value and its QoE priority weight of the target service, thereby effectively improving the reliability and accuracy of the target recovery priority.

[0057] Optionally, determining the target recovery priority of the target service according to the RTO evaluation value, the RTO priority weight, the RPO evaluation value, the RPO priority weight, the tolerable minimum QoS evaluation value, the QoS priority weight, the tolerable minimum QoE evaluation value, and the QoE priority weight includes:

[0058] First, the target business recovery priority score of the target business is calculated according to the RTO evaluation value, the RTO priority weight, the RPO evaluation value, the RPO priority weight, the tolerable minimum QoS evaluation value, the QoS priority weight, the tolerable minimum QoE evaluation value and the QoE priority weight; and then, based on the correspondence between the preset business recovery priority score and the business recovery priority, the target recovery priority corresponding to the target business recovery priority score is determined.

[0059] Specifically, when the terminal device determines the RTO evaluation value and its RTO priority weight, the RPO evaluation value and its RPO priority weight, the tolerable minimum QoS evaluation value and its QoS priority weight, and the tolerable minimum QoE evaluation value and its QoE priority weight of the target service, the target service recovery priority score of the target service can be calculated using formula (1).

[0060]

[0061] Wherein, SP represents the target service recovery priority score of the target service, RTO represents the RTO evaluation value of the target service, α represents the RTO priority weight of the RTO evaluation value, RPO represents the RPO evaluation value of the target service, β represents the RPO priority weight of the RPO evaluation value, QoS represents the tolerable minimum QoS evaluation value of the target service, represents the QoS priority weight of the tolerable minimum QoS evaluation value, QoE represents the tolerable minimum QoE evaluation value of the target service, and δ represents the QoE priority weight of the tolerable minimum QoE evaluation value;

[0062] Then, based on the correspondence between the preset business recovery priority score and the business recovery priority, the target recovery priority corresponding to the target business recovery priority score is determined. For example, when the correspondence between the business recovery score and the business recovery priority is as shown in Table 2, and the calculated target business recovery priority score of the target business is 2.15, α=35%, β=35%, When δ=10%, it can be determined that the target recovery priority of the target service is medium.

[0063] Table 2

[0064]

[0065] The business recovery priority evaluation method provided by the present invention first calculates the target business recovery priority score of the target business, and then determines the target recovery priority corresponding to the target business recovery priority score, so that the determined target recovery priority is more comprehensive and objective, thereby ensuring a more reasonable allocation of disaster recovery resources and formulation of disaster recovery strategies.

[0066] Optionally, respectively obtaining an RTO evaluation value, an RPO evaluation value, a tolerable minimum QoS evaluation value, and a tolerable minimum QoE evaluation value of the target service includes:

[0067] First, determine the loss assessment value of the target service for the interruption event; then based on the loss assessment value, obtain the RTO assessment value, RPO assessment value, tolerable minimum QoS assessment value and tolerable minimum QoE assessment value of the target service.

[0068] The loss assessment value of the target business for the interruption event may be a loss level.

[0069] Specifically, considering the objectivity of the evaluation values ​​of each indicator, the loss evaluation value of the target business for the interruption event can be determined first, that is, the terminal device can first obtain the business activity information collected from various business departments, and then determine the loss level of the target business for the interruption event from the two dimensions of financial loss impact evaluation and non-financial loss impact evaluation. For example, a subjective evaluation method can be used to analyze the loss level of the target business from the financial loss impact evaluation dimensions including operating time, user scale, business revenue and economic profit, and the financial and non-financial loss impact evaluation dimensions including corporate reputation, industry supervision, business operation qualifications, legal / litigation risks, customer satisfaction, social stability, etc. The financial loss impact evaluation and non-financial loss impact levels are mainly divided into 6 levels, and the process includes:

[0070] Impact of financial losses: Assuming that the target business is interrupted for 30 minutes, 1 hour, 4 hours, 8 hours and 1 day, evaluate the financial losses of the target business in each time period after the interruption, including qualitative and quantitative losses in terms of operating time, user scale, business revenue, operating profit, etc.

[0071] Impact of non-financial losses: Assuming that the target business is interrupted for 30 minutes, 1 hour, 4 hours, 8 hours and 1 day, evaluate the non-financial losses of the target business in various time periods after the interruption, including the impact on corporate reputation, whether the requirements of the banking regulatory authorities are met, the impact on business operation qualifications, legal / litigation risks, impact on customer satisfaction, customer churn, impact on investor confidence, as well as qualitative and quantitative losses caused by the impact on national security and social stability.

[0072] Then, the subjective assessment results of the business department on the 6-level financial loss impact and non-financial loss impact are obtained, and then the impact level is converted into a business loss impact score based on the subjective assessment results, including: unacceptable: 5 points, very serious: 4 points, serious: 3 points, general: 2 points, minor: 1 point, no impact: 0 points; then the loss assessment value of the target business for the interruption event is determined based on the loss level.

[0073] Furthermore, based on the loss assessment value of the target business for interruption events and the existing disaster recovery resource construction, the RTO assessment value and RPO assessment value of the target business are determined; based on the loss assessment value of the target business for interruption events, the tolerable minimum QoS assessment value and tolerable minimum QoE assessment value of the target business are determined.

[0074] The service recovery priority evaluation method provided by the present invention first determines the loss evaluation value of the target service for the interruption event, and then obtains the RTO evaluation value, RPO evaluation value, tolerable minimum QoS evaluation value and tolerable minimum QoE evaluation value of the target service based on the loss evaluation value, so as to achieve the objectivity and rationality of determining the service recovery RTO target, service recovery RPO target, service recovery QoS target and service recovery QoE target, thereby providing a strong basis for maximizing the experience quality and service quality of service recovery.

[0075] Optionally, obtaining an RTO evaluation value, an RPO evaluation value, a tolerable minimum QoS evaluation value, and a tolerable minimum QoE evaluation value of the target service based on the loss evaluation value includes:

[0076] First, the tolerable service interruption time range, the tolerable service data loss time range, the tolerable maximum delay, the tolerable maximum packet loss rate, the tolerable bandwidth range and the tolerable service quality score range corresponding to the loss assessment value are obtained respectively; then, based on the tolerable service interruption time range, the RTO assessment value of the target service is determined; based on the tolerable data loss time range of the service, the RPO assessment value of the target service is determined; based on the tolerable maximum delay, the tolerable maximum packet loss rate and the tolerable bandwidth range, the tolerable minimum QoS assessment value of the target service is determined; and based on the tolerable service quality score range, the tolerable minimum QoE assessment value of the target service is determined.

[0077] Specifically, from different dimensions of the loss assessment value of the target business for the interruption event, the tolerable range corresponding to each indicator can be determined, and then the assessment value of each indicator can be determined according to the different tolerable ranges. The specific process includes: combining the loss assessment value of the target business for the interruption event, determining the tolerable interruption time range of the target business, and then further determining the RTO assessment value corresponding to the tolerable interruption time range of the business according to the correspondence between the preset loss assessment value and RTO as shown in Table 3. For example, the tolerable maximum interruption degree of the target business is determined to be "serious" in combination with the loss assessment value of the target business for the interruption event, and 2 hours after the interruption occurs, the loss level of the target business is "serious", then the RTO assessment value of the target business is two hours.

[0078] Table 3

[0079]

[0080] Combined with the loss assessment value of the target business for the interruption event, the tolerable data loss time range of the target business is determined, and then the RPO assessment value corresponding to the tolerable data loss time range of the business can be further determined according to the correspondence between the preset loss assessment value and RPO as shown in Table 4. For example, the maximum tolerable interruption level of the target business is "serious", and after 30 minutes of data loss, the loss level of the target business is "serious", then the estimated RPO value of the target business is 30 minutes.

[0081] Table 4

[0082]

[0083] Combined with the loss assessment value of the target service for the interruption event, the maximum tolerable delay, maximum tolerable packet loss rate and tolerable bandwidth range of the target service are determined, and then according to the correspondence between the preset loss assessment value and QoS as shown in Table 5, the tolerable minimum QoS assessment value corresponding to the maximum tolerable delay, maximum tolerable packet loss rate and tolerable bandwidth range of the target service can be further determined. For example, the maximum tolerable interruption level of the target service is "serious", and when the delay is >5ms, the bandwidth is <1000M, and the packet loss rate is >5%, the loss level of the target service is "serious", and the tolerable minimum QoS assessment value of the target service is delay <=5ms, bandwidth >1000M, and packet loss rate <=5%.

[0084] Table 5

[0085]

[0086] Combined with the loss assessment value of the target service for the interruption event, the tolerable service quality score range of the target service is determined, and then according to the corresponding relationship between the loss assessment value and QoE as shown in Table 6, the tolerable minimum QoE assessment value corresponding to the tolerable service quality score range can be further determined. For example, the tolerable maximum interruption level of the target service is "serious", and when the tolerable image quality score (Mean Opinion Score, MOS) is <4, the loss level of the target service is "serious", and the tolerable minimum QoE assessment value of the target service is 4.

[0087] Table 6

[0088]

[0089] It should be noted that the specific process of determining the tolerable service interruption time range, tolerable service data loss time range, tolerable maximum delay, tolerable maximum packet loss rate, tolerable bandwidth range and tolerable service quality score range of the target service based on the loss assessment value of the target service for the interruption event in the present invention can be manually determined offline or online according to actual conditions, and is not specifically limited here.

[0090] In addition, it is also possible to directly obtain the tolerable interruption time range, tolerable data loss time range, tolerable maximum delay, tolerable maximum packet loss rate, tolerable bandwidth range and tolerable service quality score range of the target business without determining the loss assessment value of the target business for the interruption event. Similarly, the specific process of directly obtaining the tolerable interruption time range, tolerable data loss time range, tolerable maximum delay, tolerable maximum packet loss rate, tolerable bandwidth range and tolerable service quality score range of the target business can also be manually determined offline or online according to actual conditions, and is not specifically limited here.

[0091] The service recovery priority evaluation method provided by the present invention first obtains the service tolerable interruption time range, service tolerable data loss time range, tolerable maximum delay, tolerable maximum packet loss rate, tolerable bandwidth range and tolerable service quality score range respectively corresponding to the loss evaluation value of the target service for the interruption event, and determines the RTO evaluation value, RPO evaluation value, tolerable minimum QoS evaluation value and tolerable minimum QoE evaluation value of the target service, so as to improve the accuracy and reliability of the RTO evaluation value, RPO evaluation value, tolerable minimum QoS evaluation value and tolerable minimum QoE evaluation value, thereby laying a foundation for subsequently determining a more comprehensive and objective service recovery priority.
