1、Cisco Digital Network Architecture (Cisco DNA) Policy
Cisco DNA provides an overall operation platform, in which network architects can define and deploy end-to-end overall network-wide policies, including QoS policies that provide application priority, security policies that control user and service access, network data collection for network performance planning and problem identification / correction. With the help of Cisco DNA center tools, various strategies are expressed at the intention level and then converted into appropriate device-level configuration.
Automation
Cisco DNA can understand all networks, devices and topologies, automatically realize the intentions expressed by users, and convert them into standardized and automated configurations to convey to network devices.
Analytics and Assurance
Analytics can collect, store and analyze data in the network. The results of data analysis are based on user intentions, including charts, problem identification and correction suggestions.
Assurance can more easily handle a large amount of network data, which is integrated and provided in a more understandable format for problem identification and problem correction guidance.
Virtualization
Virtualization allows network services to be deployed based on physical devices or virtualization. With the help of virtualization technology, key network performance can be designed, deployed and managed more quickly.
Programmable Infrastructure
Network devices that support Cisco DNA can continuously adapt to new protocols through software upgrade by using UADP (Unified Access Data Plane) hardware. Using the APIs of these network devices, we can provide North and South interfaces for network and management, and support network customization and third-party system integration.
Cloud Integration
Cisco DNA can be deployed both locally and as a cloud computing component.
Security
Cisco DNA integrates security into every level, every solution and every device of the whole system.
