Description

Method and system for adjusting service fuse mechanism based on service grid

technical field

The present disclosure belongs to the field of communication technologies, and in particular relates to a service grid-based service fuse mechanism adjustment method, a service grid-based service fuse mechanism adjustment system, a computer device, and a computer-readable storage medium.

Background technique

In a microservices architecture, a single application may consist of hundreds of services, each of which may have thousands of instances, and each instance can dynamically schedule resource editors, possibly in a constantly changing state. Therefore, in a microservice architecture, service communication and service governance are extremely complex, and managing inter-service communication is very important to ensure end-to-end performance and reliability. To this end, people have proposed ServiceMesh (service mesh) for service communication and service governance.

Service Mesh is an infrastructure layer that handles inter-service communication. Service Mesh is responsible for the reliable delivery of requests in the network topology. In practice, a service mesh is usually implemented as a set of lightweight network proxies that are deployed with the application and are transparent to the application. Service Mesh moves the entire technology stack of inter-service communication down, from the application layer to the infrastructure layer. A key mechanism in Service Mesh is the service fuse mechanism. The circuit breaker mechanism is a protection mechanism for the service link. In the microservice architecture, when a microservice is unavailable or the response time is too long, the service will be degraded, and then the invocation of the microservice of the node will be blown, and the wrong response information will be quickly returned. When it is detected that the microservice invocation response of the node is normal, the invocation link is resumed. The fuse mechanism needs to be implemented by a fuse. The fuse has three states, namely the fuse closed state (Closed), the fuse open state (Open) and the fuse half-blown state (Half-Open). In the existing mechanism, The three state implementation mechanisms of the fuse are as follows:

Closed: When the number of failed calls reaches the threshold (or a certain percentage), the fuse mechanism is activated;

Open: At this time, the call to the downstream directly returns an error without going through the network, but a clock option is designed. The default clock reaches a certain time (this time is generally set as the average fault handling time), and at this time, it enters the semi-fuse state. ;

Half-Open: Allows quantitative service requests. If the calls are successful (or a certain percentage), it is considered to be restored, and the fuse is turned off. Otherwise, it is considered that it is not good, and the fuse is turned on again.

From this, it can be seen that the existing fuse activation is a method of setting a threshold or a ratio, and the fuse activation condition is a fixed state, and the fuse activation condition cannot be automatically adjusted according to conditions such as service importance and network conditions. When the network situation is complex and there are many emergencies, if manual intervention is used, it will consume a lot of manpower and cannot respond in time, which is an unreasonable application of network resources.

Detailed ways

In order to make those skilled in the art better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments.

The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. As used in the embodiments of the present disclosure and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise.

The existing fuse activation adopts the method of setting a threshold or a ratio. The fuse activation condition is a fixed state, and the fuse activation condition cannot be automatically adjusted according to conditions such as service importance and network conditions. When the network situation is complex and there are many emergencies, if manual intervention is used, it will consume a lot of manpower and cannot respond in time, which is an unreasonable application of network resources.

The technical solutions of the present disclosure and how the technical solutions of the present disclosure solve the above-mentioned technical problems will be described in detail below with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 1 is a schematic flowchart of a method for adjusting a service fuse mechanism based on a service grid according to Embodiment 1 of the present disclosure. As shown in FIG. 1 , the method includes:

Step S101: Determine the network quality required by the first service;

Step S102: determine the network quality of the current network;

Step S103: Adjust the service fuse mechanism of the first service according to the network quality of the current network and the network quality required by the first service.

The Service Mesh (Service Mesh) for service communication and service governance has a service fuse mechanism. When the number of failed microservice calls reaches the threshold, the circuit breaker will be activated, and no further microservice calls will be made, and the downstream calls will be returned directly. error; and perform corresponding processing. After the default clock reaches a certain time, this time is generally set as the average fault processing time, that is, MTTR, enters the semi-fuse state, and re-allows quantitative service requests; the threshold for the number of failed calls , when its threshold is relatively fixed, and for different services, the required network quality is different. When the network quality cannot meet its requirements, its microservices will be basically unavailable or the response time will be long; if it waits until the number of failed calls Reaching a fixed threshold, and then starting the circuit breaker, this process will waste network resources and waste time; the embodiment of the present disclosure determines the network quality required by the first service, and the first service is a service in the service circuit breaker mechanism. A service that fails many times, but does not have a high latency requirement; for this type of service, it is determined whether to adjust its service fuse mechanism according to whether the current network quality meets the required network quality. The threshold for the number of call failures can be reduced at the same time, which can reduce the waste of network resources, and perform fault processing as soon as possible to speed up the recovery of successful microservice calls.

Further, the method also includes:

Create a service classification data table, the service classification data table includes the service number of each service, the service classification type and the required network quality;

Wherein, the service classification types include high latency requirement services, medium latency requirement services and low latency requirement services;

The service classification type corresponding to the first service is a service requiring a medium delay.

Different types of services require different network quality. By recording the service number, the service classification type corresponding to the service, and the required network quality, the service classification data table shown in Table 1 below is constructed.

Table 1 Service Classification Data Sheet

serial number service number service class number Required network quality 1

The required network quality is embodied in network information such as response time, network jitter, and packet loss rate, which is determined according to its actual situation;

Services requiring high latency, that is, services that are unacceptable for service invocation failures;

Low latency requires services, that is, services that are acceptable for service invocation failures;

Service with medium latency requirement, service between high latency requirement service and low latency requirement service

For services with high latency requirements, the service fuse mechanism cannot be adjusted, while for services with low latency requirements, it has a high tolerance for latency requirements, and the service fuse mechanism does not need to be adjusted; while for services with medium latency requirements, in When the network quality is not satisfied, if the maximum number of service invocation failures is large, time will be wasted and network resources will be wasted.

Further, adjusting the service circuit breaker mechanism of the first service according to the network quality of the current network and the network quality required by the first service includes:

Determine whether the network quality of the current network matches the network quality required by the first service;

If there is a match, start the fuse according to the original service fuse mechanism of the first service;

If it does not match, the maximum number of service invocation failures of the fuse activation condition in the original service fuse mechanism of the first service is lowered to a preset value, and fuse start is performed according to the adjusted new service fuse mechanism.

If they do not match, the Service Mesh control plane will judge whether it is an occasional network problem or if the network quality caused by individual problems of the service node is lower than the network quality value required by a certain type of service traffic; if not, the Sidecar will send the The Service Mesh control plane requests to reduce the circuit breaker activation condition, that is, the maximum number of service call failures is reduced,

The Service Mesh control plane issues commands to the service agent (sidecar) to tell the service agent that the circuit breaker activation conditions for this type of service are lowered to the default value. Modify the maximum number of service invocation failures of this category on the sidecar side of the entire network. The preset value for lowering is determined based on experience. For example, the preset value is set to maxNFSC=4 (original maxNFSC=5). After the adjustment, the maximum number of service invocation failures maxNFSC becomes into 4. As a result, the existing network quality is not sufficient to ensure the implementation of this type of service, so the activation condition of the circuit breaker is lowered, so that the maximum number of service invocation failures is lowered, and the circuit breaker does not need to be activated after the service invocation fails for many times.

Further, the fuse startup according to the original service fuse mechanism of the first service includes:

When the current number of service invocation failures reaches the fuse activation condition in the original service fuse mechanism of the first service, fuse activation for the first service;

The fuse startup according to the adjusted new service fuse mechanism includes:

When the current number of service invocation failures reaches the fuse activation condition in the new service fuse mechanism of the first service, fuse activation is performed on the first service.

When the service does not adjust the fuse start conditions in its service fuse mechanism, the fuse start is performed according to the original service fuse mechanism. After adjustment, the fuse start is performed according to the adjusted new service fuse mechanism.

Further, the method also includes:

If the number of current service invocation failures reaches the fuse activation condition in the current service fuse mechanism when adjusting the service fuse mechanism of the first service, the service is blown to start.

When determining the current network quality and making a matching judgment, if the number of service invocation failures of the existing service at this time reaches the fuse start condition in the current service fuse mechanism, the fuse start is performed directly.

Further, the method also includes:

Regularly monitor the current network quality to determine the network quality of the current network;

The service breaking mechanism of the first service is adjusted periodically according to the current network quality and the network quality required by the first service.

The service mesh control plane side can perceive the network quality of the entire network, and monitor the network quality in real time at regular intervals. After adjusting the service fuse mechanism of the service, if the network quality of the current network matches the network quality required by the first service, you can choose to adjust the adjusted service fuse mechanism to the service fuse mechanism preset by the original system. If it does not match, it will not be changed. If the current service fuse mechanism is preset by the system (the original service fuse mechanism that has not been adjusted), then press to determine whether the network quality of the current network matches the network quality required by the first service. ; If it matches, then start the fusing according to the original service fusing mechanism of the first service; if it does not match, then lower the maximum number of service invocation failures of the fusing startup condition in the original service fusing mechanism of the first service to the preset value. Set the value, and start the fuse according to the new service fuse mechanism after adjustment.

The embodiments of the present disclosure can provide more fine-grained setting of fuse activation conditions. When the existing network quality is not enough to ensure the implementation of a preset category of services, the fuse activation conditions can be lowered, and there is no need to wait for service calls to fail for many times before restarting. Circuit breakers to optimize network resource utilization.
