| Summary: | 碩士 === 南台科技大學 === 資訊管理系 === 91 === The rising development of the Internet and the application of Multi-median lead the increasing demand of bandwidth. However, the only best-effort service mode in the present network architecture can’t guarantee the communicative quality; the busy network often reduces the effect of the whole network performance. Therefore, the bandwidth management techniques can make effective management and allocation for the resources of bandwidth, and promote Quality of Services (QoS) properly. Further more, it can control unusual traffic of bandwidth and allocate proper bandwidth. When there is a surplus bandwidth, it also can offer the other users to utilize.
In this thesis, we use Linux Traffic Control tool to manage the network bandwidth in campus. First we proceeds with HTB (Hierarchical Token Bucket) and U32 Filter to figure out what the main function of the bandwidth management is, and plans the bandwidth management in dormitories which is tested in practice.
The experiment result shows that Intel Pentium4 2.26GHz PC par computer with Ethernet Bridge mode could be built on the campus dormitory network that we want to manage. Each user’s IP address is one managing class with highest 512Kbit/sec bandwidth or each dorm is a logical class unit with highest 6Mbit/sec bandwidth. Now this way is run-able and summary design classifications reach up to 1973. This design way can reduce the abnormal network traffic effectively and then guarantees each user’s basic bandwidth requirement. So our design model is efficient, low cost and easy to build on campus dormitory network which bandwidth needed to be allocated fairly.
The result of the research maybe offers schools or companies how to plan properly, to allocate and share effectively, and to set a management strategy on their own bandwidth management in network.
