Detailed Description

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.

Referring to fig. 1, fig. 1 is a diagram of a network architecture in the prior art.

In fig. 1, the network comprises a control node, a middleware node, a cluster 1 and a cluster 2. A global message queue service is deployed in the middleware node, the cluster 1 includes a computing node 1, a computing node 2 and a computing node 3, and the cluster 2 includes a computing node 4, a computing node 5 and a computing node 6.

In the network architecture, messages are forwarded through a global message queue service deployed in a middleware node, and due to the limitation of service capability processing of the message queue service, when there are many computing nodes in a network, the pressure of the message queue service is inevitably increased, so that message forwarding failure may be caused, and network service interruption may be caused.

In order to solve the above problem, an embodiment of the present application provides a message processing system, which may refer to fig. 2.

The system shown in fig. 2 may include a control node, a middleware node, a cluster 1, and a cluster 2. The middleware node is provided with a message queue service 1 and a message queue service 2, the cluster 1 comprises a computing node 1, a computing node 2 and a computing node 3, and the cluster 2 comprises a computing node 4, a computing node 5 and a computing node 6.

In the system shown in fig. 2, the computing node in the cluster 1 corresponds to the message queue service 1, and the computing node in the cluster 2 corresponds to the message queue service 2, that is, the message queue service 1 is used for forwarding messages to the computing nodes in the cluster 1, and the message queue service 2 is used for forwarding messages to the computing nodes in the cluster 2.

The control node may determine a target computing node (e.g., computing node 2) for receiving a message to be sent from among the plurality of computing nodes, and may further determine a target message queue service (i.e., message queue service 1) for forwarding the message to be sent from among the plurality of message queue services (i.e., message queue service 1 and message queue service 2) based on the computing node 2, and send the message to be sent to the message queue service 1. The middleware node may receive the message to be sent through the message queue service 1, and forward the message to be sent to the computing node 2, and then the computing node 2 may execute an operation corresponding to the message to be sent.

As can be seen, a plurality of message queue services may be deployed in the middleware node, and the message that needs to be sent to the target computing node is forwarded to the determined target message queue service, that is, the service traffic may be divided into a plurality of message queue services, thereby avoiding that the same message queue service shares all the service traffic, reducing the service pressure of the message queue service, and further reducing the probability of network service interruption.

With regard to other embodiments of the above-described message processing system, reference may be made to the following detailed description of method embodiments with regard to a control node, a middleware node, and a target compute node.

Referring to fig. 3, fig. 3 is a flowchart of a message processing method provided in an embodiment of the present application, where the method may be applied to a control node in the above system, and the method may include the following steps:

s301: a computing node for receiving a message to be sent is determined from a plurality of computing nodes as a target computing node.

S302: a target message queue service for forwarding a message to be sent is determined from a plurality of message queue services based on a target computing node.

S303: and sending the message to be sent to the target message queue service, so that the middleware node forwards the message to be sent to the target computing node through the target message queue service.

As can be seen, based on the message processing method provided in the embodiment of the present application, a plurality of message queue services may be deployed in the middleware node, and a message that needs to be sent to the target computing node is forwarded to the determined target message queue service, that is, the traffic flow may be divided into a plurality of message queue services, so that the same message queue service is prevented from sharing all traffic flows, the traffic pressure of the message queue services is reduced, and the probability of network traffic interruption may be reduced.

In step S301, a Nova-API (Nova-Application Programming Interface) service may be deployed in the control node, and the control node may receive, through the Nova-API service, a message (i.e., a message to be sent) sent by a user to the computing node through the client.

The message to be sent may include an identifier of a virtual machine that the user needs to manage, and the Nova-API service may determine, according to the identifier of the virtual machine in the message to be sent, a computing node (i.e., a target computing node) where the virtual machine that the user needs to manage is located.

In one embodiment, S302 may include the steps of: and determining the message queue service corresponding to the target computing node from the corresponding relation between the preset computing node and the plurality of message queue services as the target message queue service for forwarding the message to be sent.

In the embodiment of the present application, the correspondence between the computing node and the message queue service deployed in the middleware node may be specified by a technician when the request message processing system is deployed. The number of message queue services deployed in the middleware node may be determined by a technician according to the number of compute nodes and the service requirements in the current request message processing system.

In one implementation, the correspondence may be obtained by the control node from the middleware node. For example, when a new computing node comes online, the new computing node may notify the middleware node of its corresponding message queue service, and further, the control node may obtain the correspondence between the computing node and the message queue service from the middleware node.

In an embodiment, the control node may further update the correspondence, and the method may further include the following steps: sending a first request message to the middleware node for determining a computing node in the message processing system where an update occurs; and when receiving the identification of the updated computing node and the identification of the corresponding message queue service in the message processing system, which are sent by the middleware node, updating the corresponding relation.

In one implementation, the control node may periodically request information from the middleware node for the compute nodes in the message processing system where the update occurs.

The newly online computing node may notify the middleware node of its corresponding message queue service, and accordingly, when the middleware node receives the first request message sent by the control node, the middleware node may send, to the control node, an identifier of the computing node that has been updated in the previous period and an identifier of the corresponding message queue service, and further, the control node may update the correspondence relationship according to the received information.

For example, when a computing node is newly brought online, the control node may record the computing node and the corresponding message queue service in the corresponding relationship; alternatively, when a computing node is offline, the control node may delete the computing node from the correspondence.

In one implementation, the compute node may upload a heartbeat message to the middleware node, and the middleware node may determine the offline compute node according to the heartbeat message of the compute node.

In one embodiment, S302 may include the steps of:

step one, sending a service determination message containing the identification of the target computing node to the middleware node.

And step two, when receiving the identifier of the message queue service sent by the middleware node, determining the message queue service to which the identifier of the message queue service belongs as the message queue service for forwarding the message to be sent.

The identifier of the message queue service is determined by the middleware node according to the identifier of the target computing node from the corresponding relation between the preset computing node and the plurality of message queue services.

In one implementation, the control node may send a service determination message carrying an identifier of the target computing node to the middleware node through the Nova-API service to request to determine a message queue service for forwarding the message to be sent.

After receiving the service determination message, the middleware node may determine, from the preset correspondence between the computing node and the multiple message queue services deployed by itself, a message queue service corresponding to the target computing node, and send an identifier of the message queue service to the control node.

Further, the control node may determine the message queue service to which the identifier of the message queue service belongs as a message queue service for forwarding the message to be sent (i.e., a target message queue service).

In one embodiment, the control node may further determine services (i.e., computing services) that can be provided by the computing nodes in the message processing system, and before S301, the method may further include the steps of: sending a second request message to the middleware node, wherein the second request message is used for acquiring computing services deployed in the target computing node; and receiving the identification of the computing service deployed in the target computing node, which is sent by the middleware node.

In one implementation, when a target computing node comes online, the middleware node may determine the computing services deployed in the target computing node.

Accordingly, the control node may request, from the middleware node, a query for computing services deployed in a newly online computing node (i.e., a target computing node in the embodiment of the present application) through the Nova-API service.

Based on the above processing, the control node can determine the computing services supported by the message processing system.

Referring to fig. 4, fig. 4 is a flowchart of a message processing method provided by an embodiment of the present application, where the method may be applied to a middleware node in the above system, and the method may include the following steps:

s401: and receiving the message to be sent by the control node through a target message queue service in the plurality of message queue services.

The target message queue service is determined from the plurality of message queue services based on a target computing node in the plurality of computing nodes for receiving a message to be sent.

S402: and forwarding the message to be sent to the target computing node through the target message queue service.

In step S401, the target computing node is the computing node where the virtual machine that the user needs to manage is located. The message to be sent received by the control node may include an identifier of a virtual machine that the user needs to manage, and the control node may determine, according to the identifier of the virtual machine, a target computing node where the virtual machine that the user needs to manage is located, and further may determine, based on the target computing node, a target message queue service for forwarding the message to be sent from among a plurality of message queue services deployed in the middleware node.

In one embodiment, prior to S401, the method may include the steps of: receiving a service determination message which is sent by a control node and contains an identifier of a target computing node; determining a message queue service corresponding to a target computing node from the corresponding relation between a preset computing node and a plurality of message queue services as a target message queue service; and sending the identification of the target message queue service to the control node.

In one implementation, services may also be deployed in the middleware node. When a new computing node is online, the services can determine the message queue service corresponding to the new online computing node and record the message queue service locally.

Subsequently, when the middleware node receives a service determination message which is sent by the control node through the services and contains the identifier of the target computing node, the identifier of the target computing node can be extracted, and a message queue service (namely, a target message queue service) corresponding to the target computing node is determined according to a local record, so that the identifier of the target message queue service can be sent to the control node, and correspondingly, the control node can determine that the target message queue service is the message queue service for forwarding the message to be sent.

In one embodiment, the method may further comprise the steps of: receiving a first request message sent by a control node and used for determining a computing node updated in a message processing system; and sending the identification of the computing node which is updated in the message processing system and the identification of the corresponding message queue service to the control node.

In one embodiment, before step S401, the method may further include the steps of:

step one, receiving an identifier of a target message queue service uploaded by a target computing node and an identifier of a computing service deployed in the target computing node.

And step two, recording the corresponding relation between the target computing node and the target message queue service and the computing service deployed in the target computing node.

In one implementation, when a target computing node comes online, the target computing node may actively send an identifier of a message queue service corresponding to the target computing node (i.e., a target message queue service) and an identifier of a computing service deployed by the target computing node to a services deployed in a middleware section.

Correspondingly, the middleware node may record the information locally, that is, the middleware node may determine, through the services, the message queue service corresponding to each computing node in the message processing system and the computing service deployed by each computing node.

In one embodiment, after receiving the identification of the computing service uploaded by the target computing node, the method may further comprise the steps of: and when receiving a second request message which is sent by the control node and used for acquiring the computing service deployed in the target computing node, sending the identification of the computing service deployed in the target computing node to the control node.

In one implementation, the control node may request the middleware node to query the computing service deployed in the target computing node through the Nova-API service, and accordingly, the middleware node may send an identifier of the computing service deployed in the target computing node to the control node through the services, and further, the control node may determine the computing service supported by the message processing system.

In one embodiment, the method may further comprise the steps of: and when the distance from the last time when the heartbeat message sent by the target computing node through the computing service is received reaches the preset time and the heartbeat message sent by the target computing node through the computing service is not received again, determining that the target computing node cannot provide the computing service.

In one implementation, after the target computing node is online, the target computing node may send a heartbeat message to a services service deployed in the middleware node through a computing service according to a preset period. The duration of the preset period is a preset duration.

Correspondingly, for any computing service (which may be referred to as a target computing service) in the target computing node, when the middleware node detects that the distance from the last heartbeat message sent by the target computing node through the target computing service reaches a preset time and the heartbeat message sent by the target computing node through the target computing service is not received again, it indicates that the target computing node cannot provide the target computing service currently.

Referring to fig. 5, fig. 5 is a flowchart of a message processing method provided in this embodiment, where the method may be applied to a target computing node in the above system, and the target computing node may be any computing node in the above system, and the method may include the following steps:

s501: and receiving a message to be sent, which is sent by the middleware node through a target message queue service in the plurality of message queue services.

Wherein the target message queue service is determined from a plurality of message queue services based on the target computing node.

In one embodiment, prior to step 501, the method may further comprise the steps of: and uploading the identifier of the target message queue service and the identifier of the computing service deployed in the target computing node to the middleware node.

When the target computing node is online, the target computing node may actively send an identifier of a message queue service corresponding to the target computing node (i.e., the target message queue service) and an identifier of a computing service deployed by the target computing node to the services deployed in the middleware section.

Based on the processing, the message processing system can automatically discover the lower-layer computing service, thereby avoiding the condition of service interruption caused by restarting the service when the message processing system expands the capacity and improving the reliability of the network.

In one embodiment, the method may further comprise the steps of: and sending a corresponding heartbeat message to the middleware node through the computing service according to a preset period.

In one implementation, after the target computing node is online, the target computing node may send a heartbeat message to a services service deployed in the middleware node through a computing service according to a preset period.

Correspondingly, for any computing service in the target computing node (i.e., the target computing service in the embodiment of the present application), when the middleware node detects that the distance from the last heartbeat message sent by the target computing node through the target computing service is received to reach the preset time length, and the heartbeat message sent by the target computing node through the target computing service is not received again, it indicates that the target computing node cannot provide the target computing service currently.
