Benchmarking Setup

Ribbon used the two test beds below to collect benchmarking data.

  • 1:1 HA SBC-CE with HFE 2.1 on GCP.
  • Test tools: Two PKTARTs on GCP - one for UAC in Public Subnet, and another for UAS with private Subnet.

 Performance Metrics

Note
  • The performance numbers below have no alarms or any other error, unless specified. 
  • The limiting factor is packet loss and retransmissions, unless any other is specified (excluding transcode).
  • The core-wise usage is not mentioned here as the profile used is the default in most of the cases, unless specified.
  • Packet loss data contains the maximum packet loss for end points as a percentage.
