- Abstract:
-
Traditional network structure is complicated, which limits the development of network functions. And gradually, it also exposes the shortcomings of traditional fault diagnosis algorithms. To solve this problem, this paper analyzes the development process of fault diagnosis technology in the software-defined networking (SDN) architecture in detail, and analyzes its difference from traditional network from the perspective of diagnosis mode. Firstly, the architecture of SDN, the definition of network virtualization and system monitoring methods are introduced. Then, aiming at the differences of different fault diagnosis algorithms in SDN and the problem of fault diagnosis in a virtual environment, this paper summarizes the new fault diagnosis technologies. Five types of fault diagnosis methods are summarized based on different principles of the algorithm, and the advantages and disadvantages of different types of methods are compared. Finally, this paper looks forward to the future from five aspects, which provides reference for the follow-up optimization research of fault diagnosis technology.
