1.High reliability and high availability: network services must be uninterrupted, continuous; When any device or line fails, network services can quickly converge and self-heal.

2.Application flexibility: The new generation network architecture must help application systems break existing computer room/cabinet physical location limitations, and deploy the applications anywhere under the new generation network architecture.

3.Application scalability: The new generation network architecture must have excellent adaptability to the requirements for scalability and migration of virtualization, distributed computing and big data applications.

4.High performance of network: The new generation network architecture can meet the demand of large throughput traffic forwarding brought by scaling of large-scale distributed computing systems, migration of virtual systems, deployment of big data applications and use of high-performance NAS clusters, and provide an ultra-high performance backbone network for data center.

5.Efficient and convenient O&M: The deployment of new generation network architecture must be highly automated and protocol configuration must be simple so that many configuration parameter ratios can be automatically generated, and most protocol parameters can be configured by default. It must be plug and play, convenient and easy to use like a traditional Layer 2 network.
