Introduction of centralized and distributed routing protocols

Current trends in network routing point to dynamic routing which provides flexible and efficient routing selections. The usage of dynamic routing protocols significantly promotes the rapid development of Internet. In reality, centralized routing and distributed routing techniques are critical methods to realize dynamic routing in modern communication network. In this paper, we mainly analyze the principles of centralized and distributed routing protocols respectively, including how they work, how they affect the network performance as well as advantages and disadvantages brought by these two approaches.
