Method and system for implementing outbound service based on runtime context

Abstract

The invention discloses and provides an outbound service implementation method based on contexts in operation. The method includes the steps that a computational node initiates a connection to a control end, the control end keeps the connection as a main connection after carrying out identity identification and creates process contexts, the control end judges whether a function module which is not updated exists in existing function modules of the computational node, if the result is positive, the control end updates corresponding service functions of the function module which is not updated through the main connection, the computational node loads the function module, and the control end builds a conversation connection with the computational node through the main connection and commands the computational node to carry out data calculation and result returning through the conversation connection. The invention further provides an outbound service implementation system based on the contexts in operation.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to an outbound service method and system based on runtime context. Background technique [0002] In the outbound service architecture, the control terminal instructs the computing nodes to perform data services. The main process of a typical communication model is as follows: [0003] Deploy the distributed service program in each computing node, and the distributed service program contains the necessary service process; the computing node connects back to the control terminal, and the control terminal maintains this connection as the main connection after the necessary identity verification; the control terminal A new session connection is differentiated through the main connection, and the computing node is instructed to perform data calculation and result return through the session connection. [0004] In this model, two problems need to be solved: [0005] 1. Computing nod...

[0006] 2. Resource management issues of computing nodes and control terminals: When the session of the computing service ends abnormally, for example, when the network is disconnected, the problem of resource release needs to be dealt with

The document with the patent application number CN201210521645 discloses a BOOST-based outbound RFI / RMI service implementation method and communication system, which uses a remote object as a session resource manager and uses a session contract (RMI service) to manage resources. In this mode, each service session needs to independently define the session object and contract interface. When the types of session-based services increase, the coupling between the control terminal and the computing node will increase.
