Problems solved by technology

Existing service selection schemes for multi-indicator satisfaction generally transform the multi-indicator satisfaction problem into a multi-constraint single-indicator satisfaction problem for solution. Space has prior knowledge and other problems, and in severe cases, it will be impossible to find a real optimal solution
If the service selection problem satisfied by multiple indicators is directly solved, the computational complexity and time complexity are very high, which is difficult to achieve in actual implementation

example S1I1

[0093] Atomic services S1 and S2 are parallel structures, and the topology is transformed into aggregation service S12, such as Figure 7 shown. Example S 1 I 1 , S 2 I 1 Synthetic Aggregation Service Instance S 12 I 1 , the cost of the service instance is calculated as: The delay calculation is as follows: D S 12 I 1 = D S 1 I 1 + D S 2 I 1 = 5 + 3 = 8 , The reliability calculation is as follows: R S 12 ...

Abstract

A service combination method for achieving meeting multiple performance index requirements simultaneously comprises the following steps: (1) constructing a service combination instance sequence set according to the functional requirements of a user service combination, (2) carrying out topological transformation on a service combination instance sequence according to a set method, (3) calculating the performance parameters of the service combination instance sequence, and (4) screening out a optimized service combination instance sequence meeting all the performance index requirements of the user service combination simultaneously from the service combination instance sequence set according to the set method. The service combination method can find the optimized service combination instance sequence efficiently, guarantees to meet the requirements of a user on the price, the reliability, the retardation and other service performance indexes of combination service simultaneously, and improves the service quality of complex service.

Description

technical field [0001] The invention relates to a service combination method for simultaneously satisfying multiple performance index requirements, belonging to the field of information technology, in particular to the field of Internet-based multimedia communication technology. Background technique [0002] With the development of information technology, especially the development of Internet technology and telecommunication technology, more and more intelligent services with multimedia features emerge, and these intelligent services are often much more complicated than simple voice communication services or short message services , so it is also called complex service or composite service. For example: a user uses the tour guide software in the mobile phone to visit the city, and when he sees a scenic spot of interest, he takes a picture of it, and records the questions he is interested in into audio and photos and inputs them into the tour guide software. The tour guide ...
