2. in the priority processing of request distribution, because data is sent to the RPC Proxy module for unified processing, compared with the traditional mode, the user layer does not need to care about the priority distribution processing and the selection and designation details of the load balancing resource nodes. And because the unified judgment criterion combining the preemptive priority and the non-preemptive priority is adopted, the insertion and sorting operation depending on the request priority and the priority processing difficulty are simplified, so that the time complexity of the RPC Proxy module for realizing the distribution based on the priority weight is reduced;

Detailed Description

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Interpretation of terms:

RPC: (Remote Procedure Call) a protocol that requests services from a Remote computer program over a network without knowledge of the underlying network technology. That is to say, two servers a and B, one application is deployed on the server a, and it is desired to call the method provided by the application on the server B, because there is no memory space, it cannot be called directly, and it is necessary to express the semantics of the call and to communicate the data of the call through the network.

RPC Proxy: the remote procedure call proxy.

Load balancing: the load (work task) is balanced and distributed to a plurality of operation units for operation. The method is built on the original network structure, and provides a transparent, cheap and effective method for expanding the bandwidth of the server and the network equipment, strengthening the network data processing capacity, increasing the throughput and improving the availability and flexibility of the network.

It should be noted that, an RPC Proxy module (RPC Proxy) is deployed in a distributed manner on a plurality of resource nodes in a system resource pool, and controls the whole micro-service invocation behavior through a control center, data transceiving of each micro-service node is completed through a data Proxy module, and a micro-service code is only communicated with the data Proxy module. The control center is a central control node and is responsible for regulating and controlling all micro service nodes, realizing service registration, configuration issuing and access authority configuration, having the authority for controlling the data agent module, and having the capability of collecting any data from the data agent module, thereby sensing the service operation state of the whole micro service framework network in detail according to the operation state of the data agent module. The RPC agent module provides a uniform message receiving and service query interface for upper-layer application, is responsible for realizing service discovery, flow control and communication load balancing access in a micro-service environment, is controlled by a control center, and provides functions of flow monitoring and request tracking.

Referring to fig. 1, a micro-service RPC adaptive scheduling method provided in an embodiment of the present application is applied to an RPC adaptive scheduling system including an RPC module, an RPC Proxy module, and an RPC service resource pool, and as shown in fig. 3, the method includes:

101, when the RPC module runs, selecting a corresponding preset communication mode according to the type of the data to be called, dyeing the head of the data to be called, performing packet serialization operation on the data to be called, and then sending the data to the RPC Proxy module.

It should be noted that, the RPC module supports a synchronous mode and an asynchronous mode during operation, and the data types to be called include: reliable, unreliable, stream, short message, etc., the application selects the bottom communication mode through real-time self-adaptation.

The service RPC calling process is based on the RPC module to perform dyeing processing on the head of the data to be called of the RPC according to the service and the parameters transmitted by the RPC calling; and the default self-adaptive preference strategy is http, reliable TCP, unreliable UDP, flow mode QUIC and time sensitive data KCP. And after the dyeing treatment is finished, performing packet serialization operation on the data, and sending the data to an RPC Proxy module.

And 102, responding to the request of the RPC module by the RPC Proxy module, setting the position of the data to be called in the queue to be sent according to the priority weight of the request, and updating the request priority weight of the calling data in the queue to be sent according to a preset weight updating time interval.

It should be noted that, after receiving the request of the service RPC module, the RPC Proxy module updates the state of the relevant state machine according to the request and the response attribute of the data, and inserts the data to be called into the queue to be sent according to the request priority weight.

Specifically, the RPC Proxy module responds to the RPC module service request, and after receiving the RPC module service request, the RPC Proxy module inserts the service request into the request queue according to the priority weight in the request.

In order to accelerate the request priority operation in the RPC Proxy, the priority weight is defined to be realized by a 32-Bit field, the higher 16 bits of the field are used for preempting the priority weight, and the lower 16 bits are used for the message blocking factor weight. An ordered queue based on the weight field is maintained in the RPC Proxy.

Defining an operator B as a message blocking factor weight operator, wherein the operator has the following characteristic requirements:

the output range of the parameter X (X is more than or equal to 0) is [0,65535 ], the output result is increased more slowly as X is increased (when X is very large, the system has a very serious fault problem, and priority selection strategy execution is preferentially ensured when the system is normal).

The operator B is defined as arctan (X δ) 65535X 2/pi, where δ is the message blocking factor coefficient; and delta tn is the number of message blocking time intervals, Q is Q obtained by delta tnB, and Q is a low 16-Bit blocking weight factor, so that the remote procedure call data priority of 32 bits is obtained.

And the RPC Proxy module updates the message data priority in each time window of the message priority update, so that the data with high message data priority has higher data sending right.

And 103, judging whether the RPC service is in a running state or not by the RPC Proxy module, if so, executing the step 104, and otherwise, returning information of no available service to the RPC module.

It should be noted that, the RPC Proxy module interacts with the control center, first determines whether the RPC service is available, if not, returns to the unavailable service, and if so, executes step 104.

And step 104, judging whether the difference value between the timestamp of the host load information and the current timestamp is out of limit, if so, predicting the load information through a Markov process, and performing dimensionality reduction on the load information through PCA to obtain a load weight factor, otherwise, performing dimensionality reduction on the load information through PCA to obtain the load weight factor.

It should be noted that, if available, it is determined whether the difference between the host load information timestamp and the current timestamp is out of limit when the RPC service is running.

If the load information is outdated data (the difference between the timestamp of the host load information and the current timestamp is out of limit), the load information is predicted through a Markov process. Because the server load data is similar to a random process and has Markov property, the application adopts the Markov method to predict the server running load. Then, considering that the multidimensional property of the load information (including CPU occupancy rate, memory occupancy, network bandwidth occupancy and disk IO of resource nodes) is not beneficial to rapid scheduling and sorting, the method and the device extract valuable information quantity after dimension reduction by using a principal component analysis dimension reduction mode, and facilitate subsequent unified sorting processing.

And (4) carrying out dimensionality reduction on the load information through PCA to obtain a load weight factor, and selecting an optimal load weight factor. The dimensionality reduction steps are as follows:

there are m pieces of n-dimensional data (load information).

1) The original data is grouped into a matrix X of n rows and m columns by columns.

2) Each row of X (representing an attribute field) is zero-averaged, i.e., the average of this row is subtracted.

3) And solving a covariance matrix.

4) And solving the eigenvalue of the covariance matrix and the corresponding eigenvector r.

5) And arranging the eigenvectors into a matrix from top to bottom according to the size of the corresponding eigenvalue, and taking the first k rows to form the matrix P.

6) Namely, the data after dimension reduction to 1 dimension, namely, the load weight factor.

And if the difference value between the timestamp of the host load information and the current timestamp is not out of limit, directly performing dimensionality reduction on the load information through the PCA to obtain a load weight factor.

And 105, sequencing the load weight factors, and selecting the optimal load weight factor to set RPC service routing information.

It should be noted that the load weight factors are obtained in step 104, and the optimal load weight factors are obtained in step 105 according to the load factor sorting, and the route information of the optimal RPC service is obtained when the load weight factors meet the preset conditions.

And 106, based on the position of the data to be called in the queue to be sent, calling resource nodes in the RPC service resource pool according to the RPC service routing information, and returning a calling result to the RPC module according to the priority weight of the data to be called.

And finally, the RPC Proxy module selects (requests) a certain resource node in the PRC service resource pool according to the request priority (request sequence) of the data to be called in the queue to be requested and the RPC service routing information. After the resource node (calling result) is obtained, the calling result is returned to the return RPC module according to the priority weight of the resource node.
