Other configurable options could be found in test | +| | session profile yaml file. All these options have default | +| | values which can be overwritten in test case file. | +| | | ++--------------+--------------------------------------------------------------+ +|test tool | Spirent Landslide | +| | | +| | The Spirent Landslide is a tool for functional & performance | +| | testing of different types of mobile networks. It emulates | +| | real-world control and data traffic of mobile subscribers | +| | moving through virtualized EPC network. | +| | Detailed description of Spirent Landslide product could be | +| | found here: https://www.spirent.com/Products/Landslide | +| | | ++--------------+--------------------------------------------------------------+ +|applicability | This EPC NETWORK SERVICE REQUEST test case can be configured | +| | with different: | +| | | +| | * packet sizes; | +| | * traffic transaction rate; | +| | * number of subscribers sessions; | +| | * number of default bearers per subscriber; | +| | * subscribers connection rate; | +| | * subscribers disconnection rate; | +| | * timeout after which UE goes to Idle state; | +| | * Traffic start delay; | +| | | +| | Default values exist. | +| | | ++--------------+--------------------------------------------------------------+ +|references | ETSI-NFV-TST001 | +| | | +| | 3GPP TS 32.455 | +| | | ++--------------+--------------------------------------------------------------+ +| pre-test | * All Spirent Landslide dependencies are installed (detailed | +| conditions | installation steps are described in Chapter 13- | +| | nsb-installation.rst and 14-nsb-operation.rst file for NSB | +| | Spirent Landslide vEPC tests; | +| | | +| | * The pod.yaml file contains all necessary information | +| | (TAS VM IP address, NICs, emulated SUTs and Test Nodes | +| | parameters (names, types, ip addresses, etc.). | +| | | ++--------------+--------------------------------------------------------------+ +|test sequence | description and expected result | +| | | ++--------------+--------------------------------------------------------------+ +|step 1 | Spirent Landslide components are running on the hosts | +| | specified in the pod file. | +| | | ++--------------+--------------------------------------------------------------+ +|step 2 | Yardstick is connected with Spirent Landslide Test | +| | Administration Server (TAS) by TCL and REST API. The test | +| | will resolve the topology and instantiate all emulated EPC | +| | network nodes. | +| | | ++--------------+--------------------------------------------------------------+ +|step 3 | Test scenarios run, which performs the following steps: | +| | | +| | * Start emulated EPC network nodes; | +| | * Establish subscribers connections to EPC network (default | +| | bearers); | +| | * Switch UE to Idle state after specified in test case | +| | timeout; | +| | * Send Downlink Data Notification from network to UE, that | +| | will return UE to active state. This process is continuous | +| | and during whole test run UEs will be going to Idle state | +| | and will be switched back to active state after Downlink | +| | Data Notification was received; | +| | * Disconnect subscribers at the end of the test. | +| | | ++--------------+--------------------------------------------------------------+ +|step 4 | During test run, all the metrics provided by Spirent | +| | Landslide are stored in the yardstick dispatcher. | +| | | ++--------------+--------------------------------------------------------------+ +|test verdict | The test case will create the test session in Spirent | +| | Landslide with the test case parameters and store the | +| | results in the database for benchmarking purposes. The aim | +| | is only to collect all the metrics that are provided by | +| | Spirent Landslide product for each test specific scenario. | +| | | ++--------------+--------------------------------------------------------------+ -- cgit 1.2.3-korg
