 Packets per second or PPS is a factor of the total # of packets and the throughput supported per instance. This is best understood with an example. Lets say a 1 scale unit 500-Mbps site-to-site VPN gateway instance is deployed in a virtual WAN hub. Assuming a packet size of 1400, expected PPS for that vpn gateway instance *at a maximum* = [(500 Mbps * 1024 * 1024) /8/1400] ~ 47000.
 
-Virtual WAN has concepts of VPN connection, link connection and tunnels. A single VPN connection consists of link connections. Virtual WAN supports up to 4 link connections in a VPN connection. Each link connection consists of two IPsec tunnels that terminate in two instances of an active-active VPN gateway deployed in a virtual hub. The total number of tunnels that can terminate in a single active instance is 1000, which also implies that throughput for 1 instance will be available aggregated across all the tunnels connecting to that instance. Each tunnel also has certain throughput values. For GCM algorithm, a tunnel can support up to a maximum of 1250 Mbps. In cases of multiple tunnels connected to a lower value scale unit gateway, it's best to evaluate the need per tunnel and plan for a VPN gateway that is an aggregate value for throughput across all tunnels terminating in the VPN instance.
