Embodiment

[0104] This embodiment includes the following parts:

[0105] Step 1, network service file parsing: read the file describing the network service and the inheritance relationship file, and analyze the set of input and output concepts and service quality parameters of each service. Such as image 3 As shown, the solid line box represents the service, and its response time and throughput are listed up and down. For example, the response time of Baidu place name location query service is 100 milliseconds, and the throughput is 2000 times per second. The ellipse represents the concept, which is the output or input of the service. For example, the input concept of Baidu place name location query service is the place name of the departure place and the place name of the destination. exist image 3 In , in order to reduce the intersection between lines, some concepts are aggregated into a concept set, which is represented by a solid circle. For example, the place name of the departu...

Abstract

The present invention provides a network service optimization combination method, comprising: step 1, reading and analyzing the network service description file, and processing the inheritance relationship between service input and output concepts; step 2, determining the optimization target; step 3, generating candidate combinations Fragment; step 4, analyze the bottleneck of the score combination fragment; step 5, optimize the score combination fragment; step 6, repeat steps 4 and 5 until the current score candidate combination fragment cannot be optimized, and then for each output concept of the current service, use greedy The strategy updates the four combined segments stored in the output segment dictionary; step 7, repeat steps 3-6 until the current output segment dictionary is no longer updated, obtain the score candidate combinations of the output service from the dictionary, and reverse construct to obtain the optimal Combination of services; step 8, calculating the quality of service parameters and the number of used services of the optimal service combination, and feeding back the optimal service combination, quality of service parameters and the number of services used to the user.

Description

technical field [0001] The invention relates to a network service optimization combination method. Background technique [0002] In order to ensure the selection of appropriate services among numerous network services, reduce the cost of using network services, improve the service quality of network services, and meet the needs of enterprises and users, service combination is an indispensable part. Service composition means that the designer selects some network services manually or automatically through programming through the description file of the network service, and executes these services in a certain order according to the input given by the user to obtain the output required by the user. Network services have penetrated into every corner of people's lives, and the impact of network services on people's lives is becoming more and more profound. For example, users use electronic maps to plan travel routes, and provide GPS information and destinations of current locati...
