Control Plane = vSmart(Containers or VMs)

Data Plane = Edge(vEdge, Cisco ISR/ASR/ENCS,

Whitebox)

Management = vManage(Multi-tenant or Dedicated)

Orchestration = vBond

vBond is SD-WAN Orchestrator

• Orchestrates connectivity between management, control and data plane

• Serves as the first point of authentication

• Requires public IP Address, provides NAT-T

• All other components need to know the vBond IP or FQDN

• Authorizes all control connections (white-list model)

vManage is NMS for SD-WAN• Single-tenant or Multitenant

• Single pane of glass for Day 0, Day 1 and Day 2 operations

• Enables centralized provisioning and simplifies changes

• Supports REST API, CLI, Syslog, SNMP, NETCONF

• Provides real time alerting

• Role Based Access Control

vSmart is Centralized Control Plane

• Implements control plane policies, such as service chaining, traffic engineering and per-VPN topology

• Reduces complexity of the entire network

• Establishes peering with all WAN Edges, distributes connectivity and security context

WAN Edge is your SD-WAN Data Plane

• Provides secure data plane with remote WAN Edge routers

• Establishes secure control plane with vSmart controllers

• Implements data plane and application aware routing policies

• Exports performance statistics

• Physical or Virtual form factor

Single Pane Of Glass Operations

Operations Simplicity and Visibility

Rich Analytics

vManage vAnalytics

• Cloud-first management and orchestration• Zero-touch provisioning

• Troubleshooting with simplified workflows • Advanced analytics and assurance

SD-WAN Fabric

Unified Control Plane• Overlay Management Protocol (OMP)• Runs between WAN Edge routers and vSmart

controllers and between the vSmart controllers- Inside authenticated TLS/DTLS connections

• Advertises control plane context and policies• Dramatically lowers control plane complexity and

raises overall solution scalevSmart vSmart

• Bidirectional Forwarding Detection (BFD)

• Path liveliness and quality measurement- Up/Down, loss/latency/jitter, IPSec tunnel MTU

• Runs between all WAN Edge routers in the topology- Inside SD-WAN tunnels- Across all transports- Operates in echo mode- Automatically invoked at SD-WAN tunnel

establishment- Cannot be disabled

• Uses hello (up/down) interval, poll (app-aware) interval and multiplier for detection- Fully customizable per-WAN Edge, per-transport
