Throughput Performance for Release 20.2.4

This article provides throughput performance numbers for Versa Operating SystemTM (VOSTM) Release 20.2.4.

All throughput performance testing was done under the following conditions:

  • Routing, forwarding, and Layer 7 application-aware traffic steering were activated.
  • Testing was done with UDP traffic, as specified in RFC 2544, with a 0.1 percent acceptable loss rate, using 1024 sessions with application offloading and with CPU isolation enabled.
  • The session timeout was set to high value (3600 seconds).
  • The encryption was AES128-GCM, which is the default encryption.
  • A Spirent tester was used for testing SD-WAN traffic (refer to Layer 1 traffic statistics).
  • Performance is the amount of traffic processed by the CPU; that is, it is an aggregate of WAN-to-LAN and LAN-to-WAN traffic.
  • Performance numbers were captured at 100 percent of the service load under ideal test conditions, so all numbers should be considered as maximum values.

For all testing, the following internet mix (IMIX) distribution was used:

Frame Size (Bytes) Percentage Weight
66 45 45
78 8 8
218 8 8
594 2 2
1354 16 16
1418 21 21

Versa CPE on AWS Instance

By default, AWS interfaces are SR-IOV capable. It is recommended that you use only SR-IOV capable interfaces.

AWS instances use a network I/O credit mechanism to allocate network bandwidth to instances based on average bandwidth utilization. They accrue credits when their bandwidth is below their baseline bandwidth, and they can use these credits when they perform network data transfers. For more information, open an AWS support case and ask about baseline bandwidth for the specific instance types that you are interested in.

VOS and traffic generator instances are in single virtual private cloud and AWS region.

All numbers need to be considered the maximum as claimed by AWS instance limits.

For items in the table marked with an asterisk (*), testing was limited by the AWS infrastructure or the VOS software.
