Background technique

With the increasing demand for WEB sites and the rapid development of e-commerce WEB applications, higher requirements are placed on the processing power, system reliability and service quality of WEB server systems, and the WEB server clustering technology has emerged. The WEB application server cluster system is composed of a group of servers running the same WEB application at the same time. It is like a server from the outside world. The cluster server distributes the access requests from all parties to different nodes in the system for processing, and realizes the transparency of the WEB server to the WEB client.

In the prior art, the WEB server cluster system has a front-end node, called an allocator. As shown in FIG. 1, it is an entry of the entire cluster system, and the request from the client first arrives at the allocator, and the distributor is coarser-grained. The allocation policy assigns the request to a server on the back end, and the server responds to the request content and returns it to the client through the dispatcher. The entire cluster system has a single virtual IP address, that is, the cluster address, which is actually the IP address of the allocator. That is, the allocator provides a single virtual interface for the cluster system, so the servers in the cluster are transparent to the client. Make the entire cluster system look like a single host to the outside.

In the research and practice of the prior art, the inventor found that the prior art has at least the following problems: Since HTTP (Hypertext Transfer Protocol) request and response messages need to be forwarded by the allocator, the allocator is very It is easy to become a bottleneck in the cluster system. In particular, the response message contains content such as sound or image, which is much larger than the HTTP request message. It consumes most of the processing power and time of the allocator, and it is easy to form a single point of failure, causing the entire system to crash. In addition, the coarse-grained allocation policy does not distinguish between users and service requests. Usually, after a user initially allocates a back-end server, subsequent services are served by the server for the user, and cannot support real-time scheduling during the service. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

The embodiment of the invention provides a method for service scheduling and a system and device for service scheduling. When used for WEB service scheduling, the WEB service is separated into content and control, which are respectively controlled by the service content processing unit and signaling. The unit is completed, and the service content processing unit is added to meet the requirement of expanding the service capacity according to the service requirement, and the unified control of the processing unit of all service contents by the signaling control unit can also be implemented.

In order to make the technical solutions of the present invention clearer, the following detailed description is given by way of an embodiment: Embodiment 1 As shown in FIG. 2, the details are as follows:

S101: The WEB engine control unit receives the request of the WEB client to initiate the use of the WEB service. In this embodiment, due to the wide variety of WEB clients, such as PCs and mobile phones, different terminal types have different format requirements for WEB service content. Therefore, S101 may also include a WEB client to register with the WEB engine control unit before. The process of information is as follows:

(11) The WEB client initiates a registration request to the WEB engine control unit, and the content of the request includes: user ID, user authentication information, terminal capability, service service level, network address, and the like.

The service service level indicates a temporary service level that the user selects to use the service, and is different from the service level signed by the service provider (such as an operator) when the user signs up, and the service level at the time of signing can be regarded as a default service level.

(12) The WEB engine control unit performs an authentication operation on the user, and checks user authentication information in the user database. In this embodiment, it is assumed that the user's authentication information has been written into the user database by the user's signing process to the service provider. If the authentication fails, the registration failure is returned and the reason for the failure is returned. If the authentication is passed, the registration is successful and the user is allowed to use the WEB service. (13) If the registration is successful, the WEB engine control unit simultaneously writes information about the registration request to the control policy unit.

In addition, in this embodiment, the S101 may further include a process of registering the service content processing unit with the WEB engine control unit, which specifically includes:

(21) The service content processing unit initiates a registration request message to the WEB engine control unit, and the content of the request includes: a network access permission number, a service content processing unit address, a WEB service channel capability, and a WEB service channel number.

(22) The WEB engine control unit performs an authentication operation on the network access license number of the service content processing unit, and checks the service capability of the service content processing unit. If the authentication fails, the registration failure is returned and the reason for the failure is indicated; if the authentication is passed, the registration is successfully returned, and an ID is assigned to uniquely identify the service content processing unit in the WEB engine control unit management domain.

(23) If the registration is successful, the WEB engine control unit simultaneously writes information about the registration request to the control policy unit.

S102: The request is authenticated, and the authenticating comprises: verifying, according to the saved authentication information (such as a username and a password), the permission of the user corresponding to the WEB client and whether the requested WEB service is available.

S103: If the authentication is performed, request, by the control policy unit, the WEB engine selection information of the user corresponding to the WEB service and the WEB client. The WEB engine selection information includes: a specific user, and a service corresponding to the user, a service level, and a candidate service content processing unit. The WEB engine selection information may be generated by the control policy unit according to information such as registration and subscription of the user.

For example, the control policy unit generates and saves the WEB engine selection information as shown in Table 1, and the user corresponding to the WEB client is User 1, and the control policy unit sends the user 1 corresponding information in Table 1 to the WEB engine control unit as the WEB. The engine control unit selects the basis of the business content processing unit.

Table 1 shows: The service corresponding to User 1 is Service 1 and Service 3; The service level of User 1 is Level 1; User 1 candidate service content processing unit is ID1, ID2. The service corresponding to user 2 is service 1 and service 2; the service level of user 2 is level 2; and the service content processing unit of user 2 is ID3 and ID 4.

In this embodiment, if the authentication is unsuccessful, step S113 is performed, and the reason for the unsuccessful authentication is explained.

S104: The WEB engine control unit receives the WEB engine selection information of the user corresponding to the WEB service and the WEB client from the control policy unit, and selects the service content processing unit as the WEB client corresponding according to the WEB engine selection information. The user provides the service. For example, selecting ID1 from the candidate service content processing unit provides service for user 1.

In this embodiment, factors that need to be considered when selecting a service content processing unit according to the WEB engine selection information include: user information of the WEB service, a service category used by the user, and a service level selected by the user. The specific process is as follows:

(a) The WEB services are classified according to different standards, and the services are divided into special services and general services. The special services are controlled by specific service content processing units. The ordinary services have no special requirements for the selection of service content processing units. For example, the WEB engine control unit parses out the requested Service URI (Universal Resource Identifier) to provide more reliable and better performance services for a specific type of URI, such as online shopping applications, browsing and selecting products. Services can be arranged on a general business content processing unit, while online electronic payment services are arranged on a more reliable business content processing unit.

(b) Distinguishing users: The WEB engine control unit obtains the WEB client user information in the request by parsing the requested content, and provides a differentiated service according to the information. Depending on the level of service, users can be divided into different service classes, and important users' requests can be assigned to better-performing business content processing units, or they can be given priority system response. The service level includes the service service level requested by the user when the WEB client is registered and the service level when the user signs the contract. In addition, the WEB engine control unit can select the nearest service content processing unit to provide a response according to the network location requested by the WEB client, reduce the network transmission overhead, and shorten the system delay time.

Differentiating users can also distinguish terminals, and different service content processing units can be set to serve different terminals. For example, the mobile phone can be provided by a type of service content processing unit, and the PC terminal service can be provided by another type of service content processing unit. This reduces the problem of matching and transcoding to the terminal. (c) Load balancing: The WEB engine control unit allocates the arriving request load to the service content processing unit for processing. Each service content processing unit processes part of the system request, and the sum of all service content processing unit processing requests is the total of the entire system. The number of requests. The request load is evenly distributed to each service content processing unit, so that each service content processing unit obtains the same amount of load, and can fully utilize the processing capability of each service content processing unit to provide the best average response for the WEB client. performance. The possible situation is that different services of the same user can be served by different service content processing units according to the load condition of the service content processing unit. In addition, the WEB engine control unit can provide a distributed processing function for the WEB service, deploy the service content processing unit to different regions on the network, and control multiple service content processing units to cooperate to complete the service request of the user according to the service requirement.

It can be understood that, in the specific selection, the above three points can be comprehensively considered. First, some candidate service content processing units are selected, and then the load conditions of all service content processing units at that time are analyzed, and finally at least one or at least two services are reasonably selected. The content processing unit provides the user with a WEB service.

S105-S108: Send a control command for accessing the WEB resource to the service content processing unit. The service content processing unit returns a response message of the acquired WEB resource after acquiring the WEB resource.

S109: Send a WEB service content interaction control command to the service content processing unit.

S110: After receiving the control command, the service content processing unit exchanges service content with the WEB client.

In this step, the service content processing unit and the WEB client interworking the service content may be: transmitting the WEB service content to the WEB client, receiving the service content input by the WEB client, and encoding the service stream. Processing such as conversion and encryption.

At this point, the control of using the WEB service is completed, and after that, it may also include:

S111: Receive a message sent by the service content processing unit to confirm completion of the WEB service content. S112: Respond to the service execution completion message to the WEB client.

S113: End the business.

In this embodiment, it can be seen that when the WEB service is scheduled, the WEB service is decomposed into two parts of control and content, which are respectively implemented by two units, one unit is responsible for processing WEB service control information, and another unit is responsible for WEB service content. The processing of the information, the unit responsible for the WEB service control signaling processing selects the service content processing unit according to the WEB service request, and controls the processing of the WEB service by the WEB service content processing unit. Due to the transmission of control information relative to the transmission of business content information The traffic is negligible, single point of failure can be avoided, and the real-time scheduling and full control process can be realized by the control part. In addition, since the WEB engine controller can select the service content processing unit for different services, different users, service levels, etc., it can be realized. Fine-grained scheduling strategy.

Embodiment 2: Compared with the first embodiment, the difference is that: When the service content processing unit of the service user cannot meet the requirement, the system requires a new service content processing unit to serve more users. The newly added business content processing unit needs to register with the WEB engine control unit in order to accept the management of the engine control unit. The specific process of registration is the same as the registration process of the business content processing unit to the WEB engine control unit in the first embodiment.

It can be seen in this embodiment that when the existing service content processing unit cannot meet the system requirements, the requirements for expanding the service capacity can be achieved according to the service requirements.
