| Summary: | 碩士 === 國立中正大學 === 電機工程學系 === 85 === With improvement of the networking technology,
it is feasible to provideapplications involving a lot of video
and audio transfer. Due to lack of the openapplication service
protocols, users can not easily access services on the
remoteservers. To realize the VOD service in our
campus, we have installed the VOD serverin the computer center.
Although this VOD system has supported open integratedservice
protocols, capabilities for the session and resource management
are limited.Thus, we intend to expand such capabilities for the
VOD system. The User-to-NetworkEntity for the DSM-CC is
recommended by the ISO/OSI standard body for the sessionand
resource management. In this thesis, we have studied the related
specifications andconstructed an implementation architecture
which adopts our prototyped SAAL/ATMas the underlying transport.
Following the proposed architecture, we define the class for
each componentrelated to the session and resource management. We
have implemented the softwarefor the DSM-CC U-N entity based on
the C++ language. We follow the guideline of the protocol
implementation to define the software blocks for
supportingfunctionalities of the session/transaction control and
the message transfer. We discussthe input logic flow and output
logic flow in terms of the system operation. Aftercompleting the
software coding, we conduct some testing which is built upon
theprototyped ATM network interface. From the test results, we
have learned a lessonabout the development process. Finally, we
give some hints about the future work.
