Description

Real-time resource supply flow control system and method based on delivery point

The present invention relates to IT infrastructure resource management and delivery, and more particularly to a method and system for delivery point based resource provisioning and session control in a service oriented architecture and communication environment. Background technique

The delivery of IT infrastructure resources is a hot topic in cloud computing technology research. How to connect IT equipment resources in the data center and deliver them to users in a service manner to provide IT infrastructure services to users is a basic problem to be solved by infrastructure resource delivery.

In an enterprise environment, an enterprise's IT infrastructure resources should serve the business of the enterprise and supply IT infrastructure resources for different application services. Due to the diversification of corporate business, such as development business, testing business, production and operation business, etc.; for production and business operations, different companies have different production and operation businesses, and the same enterprise has multiple production and operation categories. Business, which makes it more complicated to deliver IT infrastructure as a service in an enterprise environment. The complexity is mainly as follows: It is necessary to consider the business-centric supply of resources, which involves business resource planning (for a specific business, how many servers, storage, network resources, that is, business planning logical resources) and IT foundation Facility resource delivery operation (the business runs after real physical resources are acquired) Two stages, how to combine these two phases to realize a business-driven real-time resource supply process, which is in the enterprise environment The basic issues to be addressed in the delivery of IT infrastructure resources.

In response to this problem, consider extending the traditional IT infrastructure resource delivery to two phases of business resource delivery and physical resource (ie, IT infrastructure resource) delivery. The first phase is the delivery of business resources, that is, the delivery of logical resources required by the business. The second stage is the delivery process of real physical resources (since most enterprises adopt virtualization technology, this stage can also be real physical resources and virtual resources), that is, logical resources are mapped to real physical resources.

The implementation of these two phases requires the cooperation of multiple service components, which involves functional components of user-oriented business and functional components of resource-oriented functional components (two levels of functional components for business resource delivery and physical resource delivery). These functional components are heterogeneous, use different programming languages and interfaces, are in different protocol stacks, and how to implement communication between these heterogeneous components, components and resources. Communication (seeing resources as a functional component) and implementing flexible and dynamic binding between requests and components is the key to achieving collaboration and interaction between components.

On the other hand, because the IT infrastructure resources are at the bottom, providing resources for the above services, a small problem in the resource delivery process will seriously affect the operation of the above business, thus bringing the production and operation of the enterprise. Huge loss. Therefore, the control of the infrastructure resource delivery process is particularly critical, that is, the entire component interaction process needs to be controlled (both service quality control is required for each service node, which node has a problem, how to deal with it; and the interaction context between nodes) Control) to ensure quality of service. Many of the production operations of enterprises are services with high real-time requirements. The IT infrastructure resource delivery services also have high real-time requirements. Therefore, when the infrastructure resources are supplied to the services, the component interaction process needs to be controlled in real time. Therefore, there is a need for a method for real-time dynamic control of the interaction process of components, controlling the interaction context between components, and performing statistical and intelligent analysis on the interaction process, which ensures the integrity of the operation and the improvement of service quality.

Furthermore, in the IT infrastructure resource delivery scenario, the resource control component in the service component is ultimately bound to the resource, and the resource binding needs to be controlled.

In response to these problems, we first consider the service-oriented system environment, transform these components into services, implement hardware software, software service, and use the service bus to realize integration and communication between components, thereby transforming data center resources into clouds. service. Dynamically control the interaction process of components in real time through session control services to ensure the integrity of resource delivery and quality of service. Currently, the interaction and communication of general service components uses the Enterprise Service Bus (ESB). ESB is a software architecture model that can be used in a Service Oriented Architecture (SOA) environment to design and implement interactions and communications between software applications. The communication between the ESB and the service components connected to it is generally based on the http (Hypertext Link Protocol) and soap (Simple Object Access Protocol) protocols, both of which are connectionless protocols, which cannot control the interaction between service components ( That is, contextual relationships), the process of dynamically configuring components. In order to solve this problem, traditional research has introduced many methods, such as introducing statistical analysis in the ESB to bind components and guarantee QoS, see IBM's "J" middleware components for bundling service invocations (US 7,839,799 B2)"; Add specialized context engine middleware to control process context, update context, context-based self-learning, self-optimization, see IBM patent "Optimizing service processing based on business information, operational intelligence, and self-learning (US 7,921, 195)"; also solved from the perspective of workflow management, see IBM ¹ "System and method for dynamically configuring a multiplatform computing environment (US 7,739,243 B2)".

Although these methods can solve the dynamic configuration and context control of component interaction to some extent, they cannot control the interaction process of components in real time. Because in the IT infrastructure resource delivery scenario, IT infrastructure resources need to be delivered in real time according to the user's request, and the real-time requirements are very high. The session service has higher real-time performance, and the session control generally adopts the session control protocol SIP. Therefore, SIP can be considered to control the session between components in real time. (Because the service component itself is used to control the process of resource delivery, the session belongs to the control. Sessions at the level, different from sessions at the data level). There are also many related inventions about SIP and control sessions, most of which are used for IP network multimedia session control, as well as for PSTN and data networks, and for interaction between applications in IP networks. For example, the patent "US 7,869,787 B2" invents a method of charging a service in an IP communication system, which is charged by establishing a control session for charging between the network element and the charging function. The patent "method and apparatus for session control (US 7,590, 122 B2)" proposes a session filter associated with a protected network element. The session request is processed by the session filter before being sent to the protected network element. The protected network element will issue an event message to indicate the session condition (not a session) that is not required, such as an overload condition. The session filter will receive event information directly or indirectly, thereby reducing or stopping the session request sent to the protected network element. These two methods control the signaling by adding a dedicated session controller, which acts as a metering or protection node, but does not involve session control in different application scenarios (different services).

The patent "Session QoS control apparatus (US 7,606,914 B2)" proposes a session

The QoS control method, after receiving the session information, analyzes the session information and determines the QoS policy, and determines which nodes to set the QoS policy on. This method focuses on the setting and evaluation of QoS policies and does not involve interaction control between service components.

" Integrated application management system, apparatus and program, and integrated session management server, system, program and server chassis, and communication system, session management server and integrated application server (US 8,037, 170 B2)" The application system makes it easy to add a new application and the user to select an optional application, which enhances the interaction between applications. The system includes a client, an application server, and a management device to control the integration service from the application server to the client. For Should, manage the integration session. ¹ " Communicating application control and data information using a traffic flow over a wireless link (US 7,653,405 B2), proposes an application information communication method in a wireless network, the communication of the data information through the traffic flow on the wireless link The communication of data information is through wireless control messages in the wireless signaling associated with the traffic flow. The "Method and apparatus for controlling IP applications during resources shortage (US 7,536, 192 B2)" relates to communication sessions and resource management, one in method and system resources for maintaining the communication session, as in the case of loss or reduced bandwidth, can maintain a communication session between the mobile node. specially Wo ^{1 J "system, apparatus, and} method for providing multi-application support using a Single protocol stack (US 7,480,254 B2) ', proposes a method for defining which specific application should be pointed to in future messages in a multi-application environment (SIP is different from http because the communication node can Monitor the incoming communication). These methods mainly consider the session control between application interactions, but do not involve the interaction between the IT infrastructure resource control components, nor the resource control component to control the operation of the resources, and therefore cannot control the service component pairs. The binding and metering of the IT infrastructure resources, not to mention the virtual machine.

It can be seen that a component session control method suitable for the IT infrastructure resource delivery environment is needed, and the session state and the session context between the components are controlled in real time, so that the interaction between the service components can be effectively controlled (the service components and resources can also be controlled). Inter-activity), control the binding of service components and resources, perform statistics on the running status of service components, perform intelligent analysis through context information and statistical information, implement intelligent session and control decision support, and ensure operational integrity and service quality.

The invention will now be further described with reference to the drawings and embodiments. 1 is a general view of a delivery point based real time resource supply flow control system of the present invention. Resources here refer to hardware devices and virtual devices in the data center. The system consists of a client 11, a resource delivery control center 12, and physical POD service units 131~13n. Through the resource delivery control center 12, a control plane can be constructed to control the process of resource delivery. The client 11 is a requester of the resource service, and may include various resource requesters. In one or more preferred embodiments of the present invention, the client may include a test service department, a development service department, and an operation service department of the enterprise. The administrators of these departments request real-time resources from the control center to perform their respective businesses.

The resource delivery control center 12 is the core of the real-time control resource delivery of the present invention, and is composed of a service bus 121, a resource bus 122, a reference model unit 123, a data model unit 124, a session control service component 125, a user service component 126, and a resource control service bus. 127 composition. The reference model unit 123, the data model unit 124, and the session control service component 125 belong to a management control type component, and the functions of these management control type components are enabled throughout the entire control flow. The user service component 126 and the resource control service component 127 belong to a functional component having a specific function. The binding process (flow control) of the service component and the service request is completed by the service bus 121 and the reference model unit 123, the data model unit 124, and the session control service component 125. Control of the session is done by the session control service component 125. The service bus 121 is connected to the main functional components in the control center, and is responsible for communication between components, protocol conversion, load balancing, routing, and monitoring. The service bus 121 is coupled to the reference model unit 123, the data model unit 124, the resource bus 122, the session control service component 125, the plurality of user service components 126, and the resource control service component 127. The service bus 121 receives the resource request issued by the client 11, initiates a session control service, and schedules the request. Service bus 121 can be tied The service components associated with it, including the user service component 126 and the resource control service component 127, manage the service lifecycle and implement reuse of the service components. In a preferred embodiment of the invention, the primary service bus can be an ESB. There are multiple user-oriented service components 126, from user service component 1 to user service component n. These user service components refer to user-oriented functional modules, such as service factories, service designers, service agents, etc., providing web services, among which The messages are delivered in the form of an XML file, and the interaction between the user service components 126 is implemented by the main service bus (ESB) 121. The user service component runs the business delivery function required by the request, and multiple user service components cooperate to complete the user business delivery process. There are a plurality of resource control service components 127, from the resource control service component 1 to the resource control service component n. Unlike the user service component 126, the resource control service component 127 herein refers to some functional components for resource control, such as a resource controller such as a VM controller, a storage controller, a network controller, and the like. The resource control component service provides a resource state model to perform access control operations on the underlying resources.

The reference model unit 123 stores various data information and data relationship information such as user service information, resource reference information, and identity information, defines functional behaviors and data sources executed by each component, and provides functions for the ESB to bind the request to the service component. Indication and addressing services. The data stored in the reference model unit 123 has a transient characteristic, and as the request is executed, changes in various information are updated in the reference model. The data model unit 124 is a model of real resource states in which the storage server state, the virtual machine state, the storage state, the network state, and the lifecycle of these resource states are software representations of these physical resources. Through the resource data model, you can decide on the submission of resource requests and on which server to route resource requests.

The resource bus 122 is a distributed data service in a heterogeneous resource environment, and is responsible for communication between resource control service components and resources, and can shield different operating systems and different programming languages. The resource bus 122 is coupled to the service bus 121, the reference model unit 123, the data model unit 124, and the physical POD service unit 13, and controls communication and interaction between the resource control service component 127 and resources. The resource bus 124 mainly includes a topic-based publish and subscribe function and a QoS guarantee function. The resource bus 124 may be a distributed data service DDS, an Internet communication engine (ICE), or the like. The Session Control Service component 125 is based on the SIP protocol, which provides a standards-based way of providing IP communications for a variety of devices and applications. The session control service component 125 creates a control session for the request, controls the interaction session between the service components in real time, controls the session context, online statistics, and intelligent decision making. A dynamic binding indication between the request and the service component. The session control service component 125 mainly includes a SIP session service and a SIP management service, wherein the SIP session service refers to a session management service for controlling the creation, modification, and termination of a session in the SIP protocol, by which SIP level session control and distribution can be implemented. Transaction processing. The SIP management service is used to manage the session context of the SIP-controlled service node, the context of the resource control service component and the resource, the binding with the POD, the removal of the online application, and the provision of online application statistics services, including statistical execution requests. The number of resources used by the service node and the length of time the resource is used, as well as the number and duration of resource usage for the request, provide statistical and intelligent analysis decision services. Directly connected to the physical POD service unit 13. The session control service component will be described in detail in FIG.

The physical POD (delivery point) service unit 13 is a single delivery resource module, which includes IT equipment resources, such as the server 131, the FC SAN 132, and the IP SAN/NAS 133. These resources form a physical POD service unit 13 by a certain division. The set of devices is defined and divided in the data center network to form a resource provisioning physical unit, which can work independently without relying on other devices, and finally form a physical POD service unit 13. The physical POD service unit 13 has a resource container in which a context relationship between resources within a physical POD service unit 13 is stored. The division of POD is determined by the number of resources in the data center and the needs of the business resources to obtain a compromise result. Since the resources within the POD have contextual relationships, resource communication within the POD is easy, and communication between PODs becomes difficult. Therefore, when dividing the POD, consider both situations. In the data center, a plurality of physical POD service units 13 can be divided, from physical POD service unit 1 131 to POD service unit n 13n. Each physical POD service unit 13 is composed of an IT equipment resource module 1313, a device connection service module 1310, a device routing service module 1311, and an integrated access module 1312, wherein the integrated access module 1312 provides an API for accessing the resource control service. 2 is a general flow chart of a delivery point based real-time resource supply flow control method of the present invention. The method includes two dimensions of service flow control and session control, and session control. The specific process is as follows: Step 201: The client sends a request to request to use resources.

Step 202: The service bus receives a resource request from the client. In a preferred embodiment of the invention, the service bus is an enterprise service bus ESB.

Step 203: The service bus invokes the session control service component to create a control session for the request, and controls the real time. The interactive session between each service component through which the request passes, controls the session context, maintains the session state and connections; the components herein refer to the user service component and the resource control service component in the control center 12, step 204: the service bus is based on the request message In the information, or in the control session service and the reference model unit and the data model unit, the indication binding service component, the scheduling service; the request sent by the client carries a message, and the control session service can control the dynamic binding between the components, The behavior of the functional components and the data sources to be used are defined in the Reference/Data Models cell. In the present invention, the binding between functional components includes static binding and dynamic binding, which will be described in detail in FIG.

Step 205: After the service bus determines which service component to bind the request to, it initiates a service component processing request to maintain communication and interaction between the service components.

Step 206: Determine whether the request reaches the resource bus, and if yes, proceed to step 207. Step 207: The resource bus determines to bind the request to the physical POD service unit according to the resource state information and the POD context in the data model unit; the real state information of the resource in the data model unit, the state transition information, etc., and the POD service unit has a The container stores the associated context of the IT device resource, ensuring that the requested device resource is in the same POD service unit.

Step 208: The resource bus maintains communication and interaction between the resource control service component and the resource to ensure real-time interaction.

Step 209: The resource control service component controls the operation of the resource. In a preferred embodiment of the present invention, the resource control service component refers to a virtual machine controller (VM controller) and a resource virtual machine (VM), which is controlled by a resource. During the session, the virtual machine controller controls the operation of the virtual machine.

Step 210: The resource request sent by the client is controlled by the component of the resource delivery control center, and the resource is run to generate a resource instance, thereby completing the process of resource delivery control. Resources here refer to computing, storage, and network resources within a POD service unit.

Step 211: End the control session and release the occupied resources.

Step 212: Update the resource status in the data model unit, and update the reference relationship information in the reference model.

Step 213: End the service process and recycle resources. 3 is a flow diagram of the binding of a request and service component of the present invention. The method is that the service bus in step 204 in FIG. 2 binds the service group according to the information in the request message according to the indication in the reference/data model unit. Further refinement of the pieces. The service bus, according to the information in the request message, indicates in the reference/data model unit that the binding service component obtains a function indication of the component operation and a binding indication of the component by interacting with the reference model unit and the data model unit. Static and dynamic binding of service components and requests can be implemented. The specific process is as follows:

Step 301: The service bus receives the service request.

Step 302: The service bus determines whether the request is dynamically bound to the service component. The component here refers to the user service component and the resource control service component in the control center 12. Here, the dynamic binding is different from the static binding, and the request is not The binding mode is manually and statically determined in advance, and is flexibly and dynamically determined according to the service request and various configuration policy information. If the request is statically bound, the process proceeds to step 304, otherwise, the process proceeds to step 303.

Step 303: The service bus obtains a dynamic binding indication from the session control service component and the reference model unit and the data model unit.

Step 904: Control a session between service nodes (service components), where the service node refers to a SIP service node, that is, a user agent client and a user agent server of SIP communication. In the present invention, the SIP service node refers to each control plane. Each service component, including a user service component and a resource control service component, can be run on one or more servers.

Step 905: It is judged whether the service node is faulty. If a fault occurs, the process proceeds to step 906, otherwise, the process proceeds to step 907.

Step 909: Control the context of the resource control service component and the POD device resource, and associate the resource context in the runtime POD. Since there is a resource container in the POD service unit, the context relationship between the resources in a POD service unit is stored therein. , the context can be a resource control service Component control and access resources provide references, while resource control service components are controlled by SIP sessions, so a runtime POD context can be associated with the SIP service node's session context.

Step 910: Form the context of the entire session control through the above association.

Step 911: Online statistics on the usage of POD resources. The detailed process is shown in Figure 8.

Step 912: Analyze resource usage and the entire session control context to form knowledge and guide decisions. The decisions here include dynamic binding decisions between request and service components and resources, and some other dynamic control decisions.

Step 913: It is judged whether the control process is finished. If it is finished, the process proceeds to step 614, otherwise the determination is continued.

Step 914: Terminate the control session and release the resource. Figure 10 is a flow chart showing the control session life cycle and session relationship of the present invention. Since the control process includes two phases of user-oriented service and resource-oriented service, and the request is finally bound to the POD resource, the entire session process includes three phases, and the specific process is as follows:

The global control session refers to the total session of the entire control process, and global control. The session also includes several sub-control sessions.

Step 1003: Determine whether to enter the resource control phase, and if yes, proceed to step 704, otherwise continue to determine; the resource control phase herein refers to the phase in which the resource control service component interacts through the service bus.

Step 1004: The SIP proxy in the session control service component creates a resource control session, where the resource user agent in the SIP proxy is used to create the session, and the resource control session is a request to run to the resource control service component phase, between the resource control service components. Session, resource control session is a sub-session of global control session, and there are multiple resource control sessions under one global control session.

Step 1005: Determine whether to enter the resource binding phase, and if yes, proceed to step 1006, otherwise proceed to the step to continue to determine; the resource binding phase herein refers to the resource control service component and the POD The device resource binds and interacts to generate a phase of the resource instance, which connects the control plane and the data plane. Step 1006: The SIP proxy in the session control service component creates a resource binding session for the request, where is created by using a resource binding proxy in the SIP proxy, and the resource binding session refers to a session in which the resource control service component and the POD resource device interact. In a preferred embodiment of the present invention, if the resource bound by the resource controller is a virtual machine (VM), then a virtual machine (VM) is a resource binding session.

Step 1007: It is judged whether the resource instance is finished. If it is finished, the process proceeds to step 1008, otherwise, the process proceeds to step 1009.

Step 1008: End the resource binding session, the resource control session, and the global control session, and release the occupied resources. When the resource instance ends, the corresponding control process also ends, ending the control session.

Step 1009: Determine whether the session time exceeds the threshold. If the threshold is exceeded, go to step 1008, otherwise go to 1007 and judge again. 11 is a functional block diagram of the binding of the POD service unit and the resource control component of the present invention.
