AWS Benchmarking Setup


AWS Benchmarking Setup

Benchmarking Setup Details

  1. Benchmarking is performed on an SBC HA with HFE.
    1. The call flow includes 9 signaling messages with media.
    2. Calls are tested from Public to Private network
  2. The SBC HA with HFE and PKTART are running on the default tenant.
  3. The PKTART Tool flavor uses c5.2xlarge to benchmark all of the SBC with HFE Instances except c5.4xlarge.
    1. For the c5.4xlarge Instance, the PKTART flavor used is the same as the SBC.
  4. The performance test is done for one hour.
  5. Perflogger is used for Logs collection.
  6. There is a 2,000 sessions System Limit for M5.xlarge for default profile. 
  7. TLS/SRTP enabled at Public side traffic. Separate TLS connection (Port) used for each call. 
  8. SRTP Calls are executed from PKTART.

AWS SLB Performance Data

Deployment Types on AWS with SLB

  1. HFE/HA SBC behind HFE/HA SLB
  2. HFE/HA SBC behind HA SLB

AWS with SLB Performance Testbed

The diagram below depicts the HFE front-ending the SLB and SBC.

  • Pktarts are used as testing the SLB performance as UAC and UAS
  • 600pxFor Standalone SLB/SBC, replace HFE-SLB and HFE-SBC with standalone SLB and SBC

Note

Test parameters:

  • Tested using two SLB HFE EIPs for two different clients each. SLB had two backend SBCs
  • Tested ~4,000 session load with media enabled on m5.xlarge SLB and SBC setups
  • Switchover will take 2-6 seconds due to secondary IP movements.
