-# Project Title
+# OSM PLA
 
-One Paragraph of project description goes here
+The PLA module provides computation of optimal placement of xNFs over VIMs by matching NS specific requirements to infrastructure availability and run-time metrics, while considering cost of compute/network.
 
 ## Getting Started
 
-These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
+Please refer to the [PLA User's Guide](docs/pla_users_guide.md) for a description on how to enable and configure the placement functionality.
 
-### Prerequisites
 
-What things you need to install the software and how to install them
-
-```
-Give examples
-```
-
-### Installing
-
-A step by step series of examples that tell you how to get a development env running
-
-Say what the step will be
-
-```
-Give the example
-```
-
-And repeat
-
-```
-until finished
-```
+## Running the tests
 
-End with an example of getting some data out of the system or using it for a little demo
+The preferred method to run the PLA unit test is to use tox.
 
-## Running the tests
+`$ tox`
 
-Explain how to run the automated tests for this system
+Please note that some of the unit test modules have dependencies to Minizinc, e.g. test_mznmodels.py and test_mznPlacementConductor.py.
+If these tests are to be performed outside a PLA container context, like .e.g. from CLI or from within an IDE, setup the environment as follows (linux example):
 
 ```
-Give an example
+$ sudo snap install minizinc --classic
+$ sudo mkdir -p /minizinc/bin
+$ sudo ln -s /snap/bin/minizinc /minizinc/bin/minizinc 
 ```
 
 ## Deployment
 
-Add additional notes about how to deploy this on a live system
+PLA is an optional module in OSM. It is installed together with OSM by adding ``--pla`` to the install script.
+
+`$ ./install_osm.sh --pla`
 
 ## Built With
 
-* [Python](www.python.org/) - The language used
+* [Python](www.python.org/) - the primary programming language for OSM
+* [Minizinc](www.minizinc.org) - a free and open source constraint modelling language

+# Placement module (PLA) design description
+## Overview
+The PLA module provides computation of optimal placement of VNFs over VIMs by matching NS specific requirements to infrastructure availability and run-time metrics, while considering cost of compute/network.
+
+This document supplement the Placement Module (PLA) Users's Guide by providing details on the SW design.
+
+PLA is a separate module in the OSM architecture. As other OSM modules it runs in a Docker container.
+PLA interacts with LCM over the Kafka message bus and handles the following message:  
+* topic: pla - command: get_placement
+
+When LCM receives a ns instantiation command with config parameter `placement-engine: PLA` it shall request placement computation from PLA. 
+See PLA User's Guide for details and capabilities for different types of instantiation commands and necessary configuration of PLA.
+
+The placement computation is done by Minizinc (www.minizinc.org) on a constraints model that is created according to the content of the ns instantiation command.
+
+The minizinc models are created on demand within PLA using the Jinja2 templating language.
+
+## SW components overview
+The diagram below illustrates the important classes, data structures and libraries within PLA.
+
+![PLA SW Architecture](img/PLA_SW_Arch.png)
+
+**PLA Server**
+
+This is the PLA server (server.py).
+Capability: Produce placement suggestions based on a placement request from LCM OSM module. The get_placement() method extract information based on the referred instantiation operation id and calculates possible deployments for the NS by matching the NS specific requirements to infrastructure, - availability and, -run-time metrics,  while considering cost of compute/network.
+Collaborates with: MznPlacementConductor, NsPlacementDataFactory
+
+**MznPlacementConductor**
+
+Capability: Manages minizinc model creation, execution and processing of minizinc output. Use the NsPlacementData provided from the PLA Server and collaborates with MznModelGenerator for model creation and uses PyMzn for execution of the created minizinc model.
+Collaborates with: PLA Server, MznModelGenerator
+
+**MznModelGenerator**
+
+Capability: Create instance of MznModel using the information kept in NsPlacementData combined with Jinja2 templating language/templating engine. 
+Collaborates with: MznPlacementConductor
+
+**NsPlacementDataFactory**
+
+Capability: Knows how to create a NsPlacementData instance. Receives placement request data and collects additional information on; NSD/VNFD, Infrastructure topology, link delays and possibly more things (e.g. resource utilization, after rel.7).
+Collaborates with: PLA Server
+
+**NsPlacementData**
+
+Dictionary keeping relevant data for a placement request so that a corresponding minizinc model can be created. Content includes e.g. vim account information, price lists, network topology, link characteristics and network service characteristics.
+
+**PlacementResult**
+
+Carries processed result of the optimal placement solution as computed by minizinc
+
+**MznModel**
+
+String representation of a mzn model
+
+**PyMzn**
+
+PyMzn is a Python library providing bindings to minizinc.
+
+**Jinja2**
+
+Jinja2 is a template engine used in PLA when creating the minizinc model for a placement request.
+
+
+## Unit tests
+### Unit testing dependencies
+Some of the unit test modules have dependencies to Minizinc, e.g. test_mznmodels.py and test_mznPlacementConductor.py.
+If these tests are to be performed outside a PLA container context, like .e.g. from CLI or from within an IDE, setup the environment as follows (linux example):
+1. install minizinc as a snap from snapcraft.io/minizinc
+2. create a softlink from /minizinc/bin/minizinc to /snap/bin/minizinc to mimic the container structure in the development host
+
+```
+$ sudo snap install minizinc --classic
+$ sudo mkdir -p /minizinc/bin
+$ sudo ln -s /snap/bin/minizinc /minizinc/bin/minizinc 
+```

+# Placement module (PLA) User's Guide
+
+## Introduction
+To use the placement functionality of OSM several steps needs to be taken to configure and enable the function.
+1.     OSM needs to be installed with the PLA module included
+2.     Create the price lists for compute and transport links
+3.     Create the inventory of PoP interconnecting links
+4.     Update the PLA container with price list and inventory file
+5.     Usage - Instantiate the service using the placement engine
+
+## Install OSM including PLA
+PLA is an optional module in OSM. It is installed together with OSM by adding ``--pla`` to the install script.
+
+`$ ./install_osm.sh --pla`
+
+## Create the price lists
+The price list for compute determines the price for each VNF at each VIM (or Point of Presence - PoP). The file (vnf_price_list.yaml) is written in Yaml and is exemplified below.
+
+```
+- vnfd: testVnfOne
+  prices:
+    - vim_url: http://10.234.12.47:5000/v3
+      vim_name: OpenStack1
+      price: 10
+    - vim_url: http://10.234.12.44:5000/v3
+      vim_name: OpenStack2
+      price: 9
+    - vim_url: http://10.234.12.46:5000/v3
+      vim_name: OpenStack3
+      price: 8
+    - vim_url: http://10.234.12.43:5000/v3
+      vim_name: OpenStack4
+      price: 7
+- vnfd: hackfest_multivdu-vnf
+  prices:
+    - vim_url: http://10.234.12.47:5000/v3
+      vim_name: OpenStack1
+      price: 17
+    - vim_url: http://10.234.12.44:5000/v3
+      vim_name: OpenStack2
+      price: 18
+    - vim_url: http://10.234.12.46:5000/v3
+      vim_name: OpenStack3
+      price: 19
+    - vim_url: http://10.234.12.43:5000/v3
+      vim_name: OpenStack4      
+      price: 20
+```
+
+The price list for transport links between VIMs (PoP Interconnecting Link – PiL). In current release the price is given per link without any consideration to BW or other QoS parameter. The file (pil_price_list.yaml) is written in Yaml and is exemplified below. Note: In current OSM release the link characteristics are hard coded into this file, in future releases this data should be retrieved from the infrastructure by monitoring mechanisms.
+
+```

+
+```
+
+## Create the inventory file
+The VIMs configured in OSM are assumed to be connected to each other with transport links - PiLs. In current release the inventory file describes the available PiLs with latency and jitter. If there is no PiL in the inventory file for any pair of PoPs the placement engine will not be able to use that relation for a VL.
+
+## Update the PLA container
+Copy the price lists and inventory files to the PLA container using the following commands:
+
+`$ docker cp vnf_price_list.yaml $(docker ps -qf name=osm_pla):/placement/.`
+
+`$ docker cp pil_price_list.yaml $(docker ps -qf name=osm_pla):/placement/.`
+
+## Instantiate the service
+When creating a NS instance, it is possible to pass instantiation parameters to OSM using the `--config` option of the client or the `config` parameter of the UI. To invoke the placement engine following directives are used.
+
+`
+--config '{placement-engine: PLA}'
+`
+
+### Usage examples
+
+#### Basic usage
+`$ osm ns-create --ns_name ThreeVNFTest --nsd_name three_vnf_constrained_nsd --vim_account OpenStack1 --config '{placement-engine: PLA}'
+`
+
+Using PLA support from the GUI network service create form:
+
+![Instantiate with PLA support](img/osm_gui_ns_create.png)
+
+### With pinning of member-vnf-index: "3" to vim_account: OpenStack3
+To enable automatic placement with one (or multiple) VNFs at a pre-determined place (e.g. near CPE), PLA has the ability do placement with one or multiple VNFs pinned to datacenter(s). The pinning is done in the same way as explained in section [Multi-site deployments](https://osm.etsi.org/wikipub/index.php/OSM_instantiation_parameters#Multi-site_deployments_.28specifying_different_VIM_accounts_for_different_VNFs.29) in the OSM wiki.
+
+Example NS instantiation using CLI command (pinning one of three VNFs in the used NSD):
+`$ osm ns-create --ns_name ThreeVnfTest2 --nsd_name three_vnf_constrained_nsd --vim_account OpenStack1 --config '{placement-engine: PLA, vnf: [{member-vnf-index: “3", vim_account: OpenStack3}]}'`
+
+
+### With constraints as instantiation parameters
+It is also possible to provide constraints as instantiation parameters. Such constraints are included in a dictionary belonging to the `constraints` key as follows: 
+
+`config: {placement-engine: PLA, constraints: {<constraints specifications>}}`
+
+#### vld constraints as instantiation parameters
+Currently the supported type of constraints is placed on the vlds, and is identified with the `vld-constraints` key in the constraints specifications. Each vld that is given constraints have the form `{id: <id from nsd>, link-constraints: {latency: <max allowed latency>, jitter: <max allowed jitter>}`. It is not necessary to place constraints on all links, it is also possible to freely mix the supported constraint types `latency` and `jitter` as desired.
+
+Example NS instantiation using CLI command with constraints put on `vld_1` and `vld_2`
+
+`$ osm ns-create --ns_name ThreeVnfTest2 --nsd_name three_vnf_constrained_nsd --vim_account OpenStack1 --config '{placement-engine: PLA, vnf: [{member-vnf-index: “3", vim_account: OpenStack3}], constraints: {vld-constraints: [{id:vld_1, link-constraints: {latency: 120, jitter: 20}}, {id:vld_2, link-constraints: {latency: 120, jitter: 20 }}]}}'`
