The below table shows that there are two tenants deployed on each CPE (also referenced as Branch or Site in this table) with 4 WAN links each in the same transport domain.
As such the total SDWAN tunnels (Each SDWAN tunnel represents 1 VXLAN and 1 IPSEC tunnel) established by each CPE is represented in the row "Total Branch to Branch IP sec SDWAN tunnel from each site". This value is a multiplier of "Total number of customer tenants" and "Total Sites per tenant".
The "Total SLA paths per site" represent the sum of each permutation of the 4 local and 4 remote WAN links that are available on each CPE.

Bandwidth used for SLA by each site | 3.2 Mbps | 4.8 Mbps | 6.4 Mbps | 8 Mbps |
Bandwidth used for control plane including SLA, BGP by each site | 5.6 Mbps | 10 Mbps | 12.9 Mbps | 16.2 Mbps |
| Note: This was done when there are no flaps/alarms in the network with a controlled environment The percentage of remote sites active communicating was 5% Only worker thread 0 will be used for SLA, other worker thread will be available for data traffic including worker thread 0 | ||||
SDWAN SLA Measurement Calculator can provide you with a general idea of the amount of bandwidth needed for Control plane traffic. It also includes log traffic from Branch to Analytics via Controller.
