2、d its application. As we known, The twomost promising approaches in the area of VOIP are the protocol suites H.323 (ITU- T)and SIP (IETF).H.323 gatekeeper acts as an administrator role in H.323 network. It stands on theu

3、pper layer in the whole network, and manages all enpoints and calls located in its zone.The mainly functions for H.323 gatekeeper are:Endpoint Address Parser, Access control,Bandwidth management and Zone management. More

4、over, H.323 gatekeeper possessesthe capability of Call Control Signaling and Call management. It is impossible toconstruct a steady H.323 Network without gatekeeper.When gatekeeper high efficiency in network maintenance

5、and management, it’ s notignore problems which implement gatekeeper according to H.323 protocol presence inpractice running, It’ s resolve some problems by H.323 protocol or another method,butsome problems that run throu

6、gh the process of implement gatekeeper need moreinvestigation and discussion.This thesis introduces the design, implementation and development of a gatekeeperin a H.323 system, mainly presenting the model design of Gatek

7、eeper, and some keysolutions.This thesis is divided into two parts. The first part consists of two chapters. Firstly,the background and target about the project are present. Then, the functions ofgatekeeper in H.323 are

8、discussed in detail.The second part is divided into three chapters, chapter 3, chapter4, and chapter 5.In chapter 3, the architecture of the application and function modules are presented. Therelationship and interfaces

9、between modules are also talked about. In the forth and fifthchapter, the detailed work in designing and implementing is discussed.In the last part of this paper, experiment results are presented, meanwhile aconclusion o
