Based On The Ws-management Specification, Analysis And Research

The enterprise information system management is very important for the enterprise informationization.But the system resources to be managed are from different vendors,so the compatibility is hard to be guaranteed. The business logic will be more complicated as the enterprise grows. Meanwhile the enterprise will be cross-region,or even cross-country. So it will bring a lot of challenges for system management.Web Services technology grows popular depending on its characteristics,for example, cross-language,cross-platform and so on.WS-Management specification is published by the DMTF group which is an important specification group. It aims to use Web Service technology in the system management. WS-Management specification has referred some Web Services specifications,but it has made some modifications.Firstly,this thesis uses the Petri theory to describe three sub-specifications in WS-Management specification,WS-Transfer, WS-Enumeration and WS-Eventing.And we use Petri theory to prove the four properties of the three specifications,boundedness,liveness,integrity and forwardness.After WS-Management specification was published,some famous computer companies published some open-source projects on WS-Management specification.But most of these projects did not include the communication between the management middleware and the resources. So we design and implement a system management base on a open-source project.And we use the system management to manage the resources on the Windows platform.At last,this thesis analyzes and compares two event delivery mode in WS-Eventing,push mode and pull mode.Based on this,we put forward an advanced pull mode,and we analyze its performance using stochastic Petri nets.We find that the advanced pull mode will lighten the cached pressure on the management middleware.
