EPC Load Tester

Release Version 11.0.0.20

Date of Release: April 14, 2016

New in Release 11.0.0.20:

  • eNodeB Emulator: X2 Reset and X2 Close procedures.
  • eNodeB Emulator: X2 Setup procedure.
  • IP Traffic Emulator: Generation of IP data traffic over IPv6 GTP-U tunnels.

Release Version 1.1.0.4

Date of Release: February 14, 2012

This version includes support for the following:

  • Three new procedures: Default bearer deletion, Trace Activation and Trace Deactivation.
  • Provision to add neighbour HSS, SGW or MME to an emulated MME.
  • New User Metric tab to display current and peak values of Attached UEs, S1-U Connections and PDN Connections.
  • Provision to import testbed configuration and test scenario.
  • Check point to validate certain metrics and take action based on the validation.
  • Final validation to validate certain metrics at the end of a test scenario.
  • Graph to plot metrics.

Beta Release Version 1.0.0.2

Date of Release: December 27, 2011

Polaris Networks LTE Load Tester is a test-tool to generate traffic load on an LTE EPC Node to measure and analyze the performance of the node. LTE Load Tester Console allows user to configure testbed, create and play test scenarios by creating one or more surrounding nodes of the EPS system under test (SUT). This is the first release of the software.
