碩士 === 國立中央大學 === 資訊管理學系研究所 === 86 === Due to the growth of the Internet, the autonomous system (AS) is at highly growing rate. Large number of ASes brings the problems of routing to BGP. For example, the Internet is full of routing information. Instability of routing is increased. And, the routing efficiency is lowered. In addition, the current Internet operation efficiency cannot afford the growing rate; its backbone architecture might have congested traffic and create traffic bottlenecks. These are the important challenges which need to be overcome. In this study, a routing architecture to overcome the problems of the Internet is designed. To avoid the routing problems occurred by the increasing of ASes, the hierarchical structure is designed. To improve the operation efficiency, the use of gaterouter is suggested. The network performance can be defined as the mean time of packet flow from source to destination. Therefore, the hop number in the route is one of the most critical factors. The gaterouter could largely decrease the hop number in the routes to provide the high performance operation. In addition, the global hierarchical routing architecture distributes the traffic of the original routing bottleneck of backbone-based Internet. Moreover, it avoids the influence of single network device malfunction from disconnecting the Internet; the other transmitted traffic through the network does not share the local network bandwidth. Furthermore, the architecture also closely combines with IPv6 protocol standard as a hierarchically structural network. It provides the current and future network requirements with both scalability and efficiency.
