+Yardstick Test Case Description: NSB EPC DEDICATED BEARER
+*********************************************************
+
++-----------------------------------------------------------------------------+
+|NSB EPC dedicated bearer test case |
+| |
++--------------+--------------------------------------------------------------+
+|test case id | tc_epc_{initiator}_dedicated_bearer_landslide |
+| | |
+| | * initiator: dedicated bearer creation initiator side could |
+| | be UE (ue) or Network (network). |
+| | |
++--------------+--------------------------------------------------------------+
+|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 under |
+| | different levels of load (number of subscriber, generated |
+| | traffic throughput, etc.) for case when default and dedicated|
+| | bearers are creating and using for traffic transferring. |
+| | |
+| | 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 dedicated bearer test cases are listed below: |
+| | |
+| | * tc_epc_ue_dedicated_bearer_create_landslide.yaml |
+| | * tc_epc_network_dedicated_bearer_create_landslide.yaml |
+| | |
+| | Test duration: |
+| | |
+| | * is set as 60sec (specified in test session profile); |
+| | |
+| | Traffic type: |
+| | |
+| | * UDP; |
+| | |
+| | Packet sizes: |
+| | |
+| | * 512 bytes; |
+| | |
+| | Traffic transaction rate: |
+| | |
+| | * 5 trans/s.; |
+| | |
+| | Number of mobile subscribers: |
+| | |
+| | * 20000; |
+| | |
+| | Number of default bearers per subscriber: |
+| | |
+| | * 1; |
+| | |
+| | Number of dedicated bearers per default bearer: |
+| | |
+| | * 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 and |
+| | 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 DEDICATED BEARER test cases can be configured with |
+| | different: |
+| | |
+| | * packet sizes; |
+| | * traffic transaction rate; |
+| | * number of subscribers sessions; |
+| | * number of default bearers per subscriber; |
+| | * number of dedicated bearers per default; |
+| | * subscribers connection rate; |
+| | * subscribers disconnection rate; |
+| | * dedicated bearers activation timeout; |
+| | * DMF (traffic profile); |
+| | * enable/disable Fireball DMF threading model that provides |
+| | optimized performance; |
+| | |
+| | Default values exist. |

+| pre-test | * All Spirent Landslide dependencies need to be installed. |
+| conditions | The steps are described in NSB installation chapter for the|
+| | 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 |
+| | Administrator 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 the emulated EPC network nodes; |
+| | * Establish the subscribers connections to EPC network |
+| | (default bearers); |
+| | * Establish the number of dedicated bearers as per per |
+| | default bearer for each subscriber; |
+| | * Create the sessions and transmit traffic through EPC |
+| | network nodes during the specified traffic duration time; |
+| | * Disconnect dedicated bearers; |
+| | * 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. |
