+Network Services Benchmarking (NSB)
+=====================================
+
+Abstract
+========
+
+.. _Yardstick: https://wiki.opnfv.org/yardstick
+
+This chapter provides an overview of the NSB, a contribution to OPNFV
+Yardstick_ from Intel.
+
+Overview
+========
+
+GOAL: Extend Yardstick to perform real world VNFs and NFVi Characterization and
+benchmarking with repeatable and deterministic methods.
+
+The Network Service Benchmarking (NSB) extends the yardstick framework to do
+VNF characterization and benchmarking in three different execution
+environments viz., bare metal i.e. native Linux environment, standalone virtual
+environment and managed virtualized environment (e.g. Open stack etc.).
+It also brings in the capability to interact with external traffic generators
+both hardware & software based for triggering and validating the traffic
+according to user defined profiles.
+
+NSB extension includes:
+ • Generic data models of Network Services, based on ETSI specs
+ • New Standalone context for VNF testing like SRIOV, OVS, OVS-DPDK etc
+ • Generic VNF configuration models and metrics implemented with Python
+ classes
+ • Traffic generator features and traffic profiles
+ • L1-L3 state-less traffic profiles
+ • L4-L7 state-full traffic profiles
+ • Tunneling protocol / network overlay support
+ • Test case samples
+ • Ping
+ • Trex
+ • vPE,vCGNAT, vFirewall etc - ipv4 throughput, latency etc
+ • Traffic generators like Trex, ab/nginx, ixia, iperf etc
+ • KPIs for a given use case:
+ • System agent support for collecting NFvi KPI. This includes:
+ o CPU statistic
+ o Memory BW
+ o OVS-DPDK Stats
+ • Network KPIs – eg, inpackets, outpackets, thoughput, latency etc
+ • VNF KPIs – packet_in, packet_drop, packet_fwd etc
+
+Architecture
+============
+The Network Service (NS) defines a set of Virtual Network Functions (VNF)
+connected together using NFV infrastructure.
+
+The Yardstick NSB extension can support multiple VNFs created by different
+vendors including traffic generators. Every VNF being tested has its
+own data model. The Network service defines a VNF modelling on base of performed
+network functionality. The part of the data model is a set of the configuration
+parameters, number of connection points used and flavor including core and
+memory amount.
+
+The ETSI defines a Network Service as a set of configurable VNFs working in
+some NFV Infrastructure connecting each other using Virtual Links available
+through Connection Points. The ETSI MANO specification defines a set of
+management entities called Network Service Descriptors (NSD) and
+VNF Descriptors (VNFD) that define real Network Service. The picture below
+makes an example how the real Network Operator use-case can map into ETSI
+Network service definition
+
+Network Service framework performs the necessary test steps. It may involve
+ o Interacting with traffic generator and providing the inputs on traffic
+ type / packet structure to generate the required traffic as per the
+ test case. Traffic profiles will be used for this.
+ o Executing the commands required for the test procedure and analyses the
+ command output for confirming whether the command got executed correctly
+ or not. E.g. As per the test case, run the traffic for the given
+ time period / wait for the necessary time delay
+ o Verify the test result.
+ o Validate the traffic flow from SUT
+ o Fetch the table / data from SUT and verify the value as per the test case
+ o Upload the logs from SUT onto the Test Harness server
+ o Read the KPI’s provided by particular VNF
+
+Components of Network Service
+------------------------------
+
+* *Models for Network Service benchmarking*: The Network Service benchmarking
+ requires the proper modelling approach. The NSB provides models using Python
+ files and defining of NSDs and VNFDs.
+
+The benchmark control application being a part of OPNFV yardstick can call
+that python models to instantiate and configure the VNFs. Depending on
+infrastructure type (bare-metal or fully virtualized) that calls could be
+made directly or using MANO system.
+
+* *Traffic generators in NSB*: Any benchmark application requires a set of
+ traffic generator and traffic profiles defining the method in which traffic
+ is generated.
+
+The Network Service benchmarking model extends the Network Service
+definition with a set of Traffic Generators (TG) that are treated
+same way as other VNFs being a part of benchmarked network service.
+Same as other VNFs the traffic generator are instantiated and terminated.
+
+Every traffic generator has own configuration defined as a traffic profile and
+a set of KPIs supported. The python models for TG is extended by specific calls
+to listen and generate traffic.
+
+* *The stateless TREX traffic generator*: The main traffic generator used as
+ Network Service stimulus is open source TREX tool.
+
+The TREX tool can generate any kind of stateless traffic.

+
+Supported testcases scenarios:
+• Correlated UDP traffic using TREX traffic generator and replay VNF.
+ o using different IMIX configuration like pure voice, pure video traffic etc
+ o using different number IP flows like 1 flow, 1K, 16K, 64K, 256K, 1M flows
+ o Using different number of rules configured like 1 rule, 1K, 10K rules
+
+For UDP correlated traffic following Key Performance Indicators are collected
+for every combination of test case parameters:
+ • RFC2544 throughput for various loss rate defined (1% is a default)

+
+Enable yardstick virtual environment
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Before executing yardstick test cases, make sure to activate yardstick
+python virtual environment
+
+::
+ source /opt/nsb_bin/yardstick_venv/bin/activate
+
+
+Examples and verifying the install
+----------------------------------
+
+It is recommended to verify that Yardstick was installed successfully
+by executing some simple commands and test samples. Before executing yardstick
+test cases make sure yardstick flavor and building yardstick-trusty-server
+image can be found in glance and openrc file is sourced. Below is an example
+invocation of yardstick help command and ping.py test sample:
+::
+
+ yardstick –h
+ yardstick task start samples/ping.yaml
+
+Each testing tool supported by Yardstick has a sample configuration file.
+These configuration files can be found in the **samples** directory.
+
+Default location for the output is ``/tmp/yardstick.out``.
+
+
+Run Yardstick - Network Service Testcases
+-----------------------------------------
+
+NS testing - using NSBperf CLI
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+::
+
+ source /opt/nsb_setup/yardstick_venv/bin/activate
+ PYTHONPATH: ". ~/.bash_profile"
+ cd <yardstick_repo>/yardstick/cmd
+ Execute command: ./NSPerf.py -h
+ ./NSBperf.py --vnf <selected vnf> --test <rfc test>
+ eg: ./NSBperf.py --vnf vpe --test tc_baremetal_rfc2544_ipv4_1flow_64B.yaml
+
+NS testing - using yardstick CLI
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+::
+
+ source /opt/nsb_setup/yardstick_venv/bin/activate
+ PYTHONPATH: ". ~/.bash_profile"
+ Go to test case forlder type we want to execute.
+ e.g. <yardstick repo>/samples/vnf_samples/nsut/<vnf>/
+ run: yardstick --debug task start <test_case.yaml>
