Cisco DNA Assurance provides three key differentiators that our competitors are unable to match:

Proactive approach to guided remediation: Cisco DNA Assurance uses AI and machine learning to analyze network data and provide insights on network performance, issues, and optimization. It also offers guided remediation options that automate the process of issue resolution and performance enhancement. This reduces manual troubleshooting operations and saves time and resources for network administrators12.

Apple Insights: Cisco DNA Assurance integrates with Apple devices and applications to provide enhanced visibility and analytics on the user experience and network performance. It also leverages the Fast Lane feature to prioritize critical iOS and macOS traffic over the wireless network. This improves the quality of service and collaboration for Apple users and applications13.

Network time travel: Cisco DNA Assurance allows network administrators to go back in time and view the network state and health at any given point. This enables them to identify the root cause of issues, compare network performance over time, and troubleshoot historical problems. This feature is unique to Cisco DNA Assurance and provides a powerful tool for network analysis and optimization1 .

The protocol that runs between the vSmart controllers and between the vSmart controllers and the vEdge routers, and unifies all control plane functions under a single protocol umbrella is the Overlay Management Protocol (OMP)12. OMP is a proprietary protocol that is designed to enable the Cisco SD-WAN solution, which provides a software overlay that runs over standard network transport, including MPLS, broadband, and internet to deliver applications and services3. OMP provides the following services12:

Orchestration of overlay network communication, including connectivity among network sites, service chaining, and VPN or VRF topologies

Distribution of service-level routing information and related location mappings

Distribution of data plane security parameters

Central control and distribution of routing policy

OMP is an all-encompassing information management and distribution protocol that enables the overlay network by separating services from transport. Services provided in a typical VPN setting are usually located within a VPN domain, and they are protected so that they are not visible outside the VPN. In such a traditional architecture, it is a challenge to extend VPN domains and service connectivity. OMP addresses these scalability challenges by providing an efficient way to manage service traffic based on the location of logical transport end points. This method extends the data plane and control plane separation concept from within routers to across the network2.

 Cisco ISE benefits our customers by providing network access control and helping them stop and contain real-time threats. Network access control is the ability to enforce policies on who and what can access the network, based on the identity and context of users, devices, and applications. Cisco ISE allows customers to authenticate, authorize, and audit network access, as well as to segment and isolate network traffic based on security and compliance requirements. Cisco ISE also helps customers stop and contain real-time threats by leveraging intel from across the network and security ecosystem, and by automating threat response actions. Cisco ISE can integrate with various security solutions, such as Cisco Stealthwatch, Cisco Firepower, and Cisco Umbrella, to detect and mitigate attacks on the network quickly and effectively. References:
