Benchmarking Setup
The two test beds used to collect benchmarking data are depicted below.
- 1:1 HA SBC-CE with HFE 2.1 on Azure.
- Test tools: Two PKTARTs on Azure, one for UAC in Public Subnet and other one for UAS with private Subnet.

Benchmarking Setup Details
- The performance number below has no alarms or any other error unless specified.
- The limiting factor is packet loss and re-transmissions unless any other is specified(excluding trans-code).
