Embodiment

[0030] model definition

[0031]As a remote object invocation method, SOAP can be divided into two parts: request and feedback. The request message mainly contains the name and parameters of the service to be called, and the feedback message contains the service calculation result expected by the client. Is a function, the SOAP request is an instruction to call the function, and the SOAP feedback is the result of the function call. Obviously, under this computing model, it is unrealistic to pass large-scale binary multimedia data into the function as parameters. In a general programming model, if you need to let a function process large-scale data, such as transcoding an AVI-encoded movie into FLV format, generally store the data and then pass the file name as a parameter to the function, so that the function can index to the file and process it. The SOAP extension defined in this embodiment derives from this idea. The formal description of the remote object access model ex...

Abstract

The present invention relates to a method for invoking a data-intensive multimedia service based on extended SOAP. The involved entities include an extended SOAP client and an extended SOAP server. The invocation method includes: 1) the client sends an extended SOAP request message to the server, The message includes a message body part and an attachment part, the message body part includes the name of the requested service, the parameter name and instance value of the requested service, and the association relationship between the parameter and the attachment entity; the attachment part includes the name of the requested service The attachment entity associated with the parameter name of the attachment, the attachment entity includes the attachment metadata information and the binary data contained in the attachment file; 2) The server receives the extended SOAP request message, calls the service corresponding to the requested service in the message function function and obtain the calculation result, the calculation result includes the function return value to be returned and some possible processed attachment data; 3) the server returns the extended SOAP feedback message to the client, and the message carries the obtained in step 2) calculation results.

Description

technical field [0001] The invention relates to the technical field of Internet Web services, and more specifically, the invention relates to a data-intensive multimedia service calling method based on extended SOAP. Background technique [0002] Due to the need to process multimedia audio and video data, multimedia services often contain continuous and highly correlated data streams in time and space, which is a typical data-intensive service. For this reason, multimedia applications are generally implemented as a single, tightly coupled complete system. This makes the establishment, maintenance, upgrade and integration of multimedia services with other services a difficult, expensive and time-consuming problem. In addition to multimedia services, data-intensive services also include data hosting, large-scale data analysis such as data mining applications, etc. These data-intensive services also have the problem of difficulty in integrating with other services. [0003] O...
