| Summary: | 碩士 === 樹德科技大學 === 資訊工程學系 === 93 === With the improvement of technology, growth of Internet, what we pursue is not the bandwidth, but the service quality (Quality of services) Because the wider the bandwidth, the more users will enjoy the Internet convenience. However, the present Internet structure only provides Best Effort, so it couldn't ensure the transmission quality effectively.
If we could combine Bandwidth Control Management with the limited resources and make efficient management, the smallest guaranteed bandwidth of Per Flow would enhance the transmission service quality.
In this thesis, we share one Modify Deficit Weighted Round Robin Packet Scheduling, and use Time Sliding Windows Three Color Maker to execute Traffic Analysis. It also allows the smallest guaranteed bandwidth to enter the Policy and Admission Control to reach the setup order, bandwidth guarantee and speed control these service need.
So far we have some methods, such as DRR(Deficit Round Robin)、WRR(Weighted Round Robin)、TBF(Token Bucket Filter)、RSVP(Resource Reservation Protocol)、Diffserv (differentiated service). These are the limited bandwidth resource to provide Internet service quality. But these methods are not quite enough since they have their own advantages and disadvantages. Especially it will affect the router working ability in the Flow Traffic management.
Now we choose some good methods to integrated bandwidth allocation, resource reservation, and through packet calculation and Per-Flow smallest guaranteed bandwidth, these are so-called bandwidth overbooking reservation protocol. Last we will adapt Network Simulator 2 to simulate the experiment to prove our method is good.
