Yardstick Test Case Description: NSB EPC DEFAULT BEARER
*******************************************************
+-----------------------------------------------------------------------------+
|NSB EPC default bearer test case |
| |
+--------------+--------------------------------------------------------------+
|test case id | tc_epc_default_bearer_landslide_{dmf_setup} |
| | |
| | * dmf_setup: single or multi dmf test session setup; |
| | |
+--------------+--------------------------------------------------------------+
|metric | All metrics provided by Spirent Landslide traffic generator |
| | |
+--------------+--------------------------------------------------------------+
|test purpose | The Spirent Landslide product provides one box solution which|
| | allows to fully emulate all EPC network nodes including |
| | mobile users, network host and generate control and data |
| | plane traffic. |
| | |
| | This test allows to check processing capability of EPC under |
| | different levels of load (number of subscriber, generated |
| | traffic throughput) for case when only one default bearer is |
| | using for transferring traffic from UE to Network. |
| | |
| | It's easy to replace emulated node or multiple nodes in test |
| | topology with real node or corresponding vEPC VNF as DUT and |
| | check it's processing capabilities under specific test case |
| | load conditions. |
| | |
+--------------+--------------------------------------------------------------+
|configuration | The EPC default bearer test cases are listed below: |
| | |
| | * tc_epc_default_bearer_create_landslide.yaml |
| | * tc_epc_default_bearer_create_landslide_multi_dmf.yaml |
| | |
| | Test duration: |
| | |
| | * is set as 60sec (specified in test session profile); |
| | |
| | Traffic type: |
| | |
| | * UDP - for single DMF test case; |
| | * UDP and TCP - for multi DMF test case; |
| | |
| | Packet sizes: |
| | |
| | * 512 bytes for UDP packets; |
| | * 1518 bytes for TCP packets; |
| | |
| | Traffic transaction rate: |
| | |
| | * 5 trans/s.; |
| | |
| | Number of mobile subscribers: |
| | |
| | * 20000; |
| | |
| | Number of default bearers per subscriber: |
| | |
| | * 1. |
| | |
| | The above fields and values are the main options used for the|
| | test case. 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 DEFAULT BEARER test cases 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; |
| | * DMF (traffic profile); |
| | * enable/disable Fireball DMF threading model that provides |
| | optimized performance; |
| | |
| | Default values exist. |

+--------------+--------------------------------------------------------------+
| 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 (only |
| | default bearers are established); |
| | * Create the sessions and transmit traffic through EPC |
| | network nodes during the specified traffic duration time; |
| | * 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. |
