| Summary: | 碩士 === 元智大學 === 資訊工程學系 === 90 === Because of the diversity of Internet information transit such as Voice, Data and Video, the traditional Integrated Service Model can no longer satisfy the users’ requirements for the different qualities of services. A Differentiated Services Model was designed to meet the different transit stratagem for the services of different Classes and different charging standards for ISP business. Along with the rapid increase in transit speed, the Differentiated Services Model seems to lag behind, especially in the interconnected switches for different Internet services. To adjust the channel bandwidth of the (frequency) temporarily or regularly becomes a pressing task needed to be conquered. An important internet technique MPLS (Multi Protocol Label Switch), guaranteeing the qualities of the transited materials in internet, can insure high qualities of an internet terminal to terminal transit, with no need to service the flowing paths of datagram information in the current information. Besides, it can improve the expansion of Internet and offer a simple service class to the class-marked ISP. With its characteristic in marking short, simple, fixed lengths, the MPLS can provide a compact way of information transit. The purpose of the thesis is to create a new Bandwidth Control System for the Differentiated Services Model and MPLS. The System can adjust itself automatically according to the temporary adjustment, regular adjustment and the block out percentage of the bandwidth; hence, it can effectively increase the usage percentage and cut down the block out percentage of the bandwidth. Hopefully the System can offer a connected principle for the Interconnected Service Quality solving the major factors that influence the qualities while using Interconnected. Judging from the effect of the whole, and finding out different service qualities for different Classes, the auto adjustment principle (the System) can offer a completely different style of guaranty for different quality of services.
