Study on High-reliability Architecture for Network Cloud

Network cloud has been continuously promoted for more than 10 years. Nowadays, the scope of network cloud continues to expand due to the actively commercial deployment based on network cloud equipment. However, major communication network failures have occurred frequently, with long duration, wide impact range, and difficulty in meeting the reliability requirements of network services. Bringing changes on network structure by introducing virtual machines or container, network cloud owes higher difficulty in maintaining reliability. To this end, we propose a multi-level high-reliability architecture for network cloud including the important components and technologies based on the study of the high-reliability evolution model, which analyzes high-reliability technologies development in network cloud. Moreover, a system verification for this proposed high-reliability framework is completed on a certain network cloud service platform with a small user scale.
