The Research And Implementation Of Telephone Simulation Experiment System Based On SIP

With the continuous development of computer network technology,the applications like IP Phones become more and more popular.Under these circumstances,SIP as one of the most important protocols in the Next Generation Network,obtains more and more attention.Many colleges regard the knowledge of SIP as the required content of computer major.Therefore,learning the knowledge of SIP has important meanings to professional technicians.In order to help people quickly learn the knowledge of SIP,this paper introduces the design of a reusable experiment system framework developed on Windows Operation System,and the implementation of a telephone simulation experiment system based on the framework.This paper firstly introduces the research background,the actual signification,and the relation technology of this issue.And the relation technology includes the knowledge of SIP and the development of applications on Windows.After that,through comparing SIP with other similar protocols,this paper explains the importance of studying knowledge of SIP combined with the current situation.Then,by analyzing the common methods of learning SIP knowledge,this paper carries out the functional demands and the non-functional demands of the experiment system according to the insufficient of the common methods.Next,this paper introduces the design and implementation of a reusable experiment system framework based on a message-drive system.And this framework also adopts the idea of separating code and resources and support developers to customize the functional modules.With this framework,the paper designs and implements the experiment system.Finally,the experiment system and the framework are passed some systematic tests,which results shows that they are correct and reliable as expected.During the research of this issue,the experiment system and the framework has been designed and implemented.The framework makes sense in fast developing experimental applications of the same type.In addition,the experiment system is meaningful to help people learn knowledge of SIP more quickly and intuitively.
