Fabric Structure
Software-Defined WAN (SD-WAN)
the orchestration plane
management plane
control plane
data plane
Software-Defined Access (SD-Access)
What
an overlay network (virtual network) built over an underlay network (physical network) using overlay tunneling technologies such as VXLAN
Cisco Campus fabric solution
: includes all of the features and protocols (control plane, data plane, management plane, and policy plane) to operate the network infrastructure.
Cisco DNA Center
: managed all the SDA solution
Why
Network automation
: replaces manual network device configurations through a single point of automation, orchestration use of Cisco DNA Center
manageable, flexible, secure (by means of encryption), and scalable
Network assurance and analytics
: using telemetry to proactive prediction security-related risks , including encrypted traffic
Host mobility
: provides host mobility for both wired and wireless clients
Cisco Identity Services Engine (ISE)
: provides the contextual information required for users and devices to implement security policies
Policy enforcement
: policies based on group-based policies using Security Group Access Control Lists (SGACLs) provides a simpler and scalable form of policy enforcement based on identity instead of an IP address.
Secure segmentation
: easier to segment the network to support guest, corporate, facilities, and IoT-enabled infrastructure.
Network virtualization
: leverage a single physical infrastructure to support multiple virtual routing and forwarding (VRF) instances
the nodes
, fabric control plane
data plane
