+--------------------------------------------------
-The Network Topology Simulator is a framework that allows simulating devices that expose a management interface through a NETCONF/YANG interface.
+The Network Topology Simulator is a framework that allows simulating Network Functions (NF) that expose a management interface via NETCONF/YANG.

-## Overview
-===========
+The NETCONF/YANG management interface is simulated, and any YANG models can be loaded by the framework to be exposed. Random data is generated based on the specific models, such that each simulated NF presents different data on its management interface.

The NTS Manager can be used to specify the simulation details and to manage the simulation environment at runtime.
-Each simulated device is represented as a docker container, where the NETCONF Server is running. The creation and deletion of docker containers associated with simulated devices is handled by the NTS Manager. The NTS Manager is also running as a docker container and exposes a NETCONF/YANG interface to control the simulation.
+Each simulated NF is represented as a docker container, where the NETCONF Server is running. The creation and deletion of docker containers associated with simulated NFs is handled by the NTS Manager. The NTS Manager is also running as a docker container and exposes a proprietary NETCONF/YANG interface to control the simulation.
-## NTS Manager
-==============
+NTS Manager
+-----------
The purpose of the NTS Manager is to ease the utilization of the NTS framework. It enables the user to interact with the simulation framework through a NETCONF/YANG interface. The user has the ability to modify the simulation parameters at runtime and to see the status of the current state of the NTS. The NETCONF/YANG interface will be detailed below.

Under the **network-functions** there is the **network-function** list. This list is automatically populated by the NTS Manager at start time with the available network functions. No changes at the actual list are allowed (adding or removing elements), only the changes of the properties of the elements have effect. The structure of an element of this list is described below:
-* **function-type** - the function type
-
-* **started-devices** - represents the number of simulated devices. The default value is 0, meaning that when the NTS is started, there are no simulated devices. When this value is increased to **n**, the NTS Manager starts docker containers in order to reach **n** simulated devices. If the value is decreased to **k**, the NTS Manager will remove docker containers in a LIFO manner, until the number of simulated devices reaches **k**
-
-* **mounted-devices** - represents the number of devices to be mounted to an ODL based SDN Controller. The same phylosophy as in the case of the previous leaf applies. If this number is increased, the number of ODL mountpoints increases. Else, the simulated devices are being unmounted from ODL. The number of mounted devices cannot exceed the number of started devices. The details about the ODL controller where to mount/unmount are given by the **sdn-controller** container
-
-* **mount-point-addressing-method** - addressing method of the mount point. Possible values are:
-
- + \*docker\-mapping\* \- [default value] future started simulated devices will be mapped on the Docker container
-
- + \*host\-mapping\* \- future started simulated devices will me mapped on the host's IP address and port based on \*base\-port\*
-
-* **docker-instance-name** - the prefix for future simulated devices (to this name a dash and an increasing number is added)
-
-* **docker-version-tag** - a specific version tag for the Docker container to be ran. if empty, the latest version is ran
-
-* **docker-repository** - the prefix for containing the Docker repository information. if local repository is used, value can be either blank or *local*
-
-* **fault-generation** - container which groups the fault generation features, explained later
-
-* **netconf** - container with settings for enabling or disabling netconf features
-
- \* \*\*faults\-enabled\*\* \- enable or disable faults over netconf
-
- \* \*\*call\-home\*\* \- enable the NETCONF Call Home feature. If set to 'true', each simulated device, when booting up, will try to Call Home to the SDN Controller.
-
-* **ves** - container with settings for enabling or disabling VES features
-
- \* \*\*faults\-enabled\*\* \- enable or disable faults over VES
-
- \* \*\*pnf\-registration\*\* \- enable PNF registration on start
-
- \* \*\*heartbeat\-period\*\* \- the number of seconds between VES heartbeat messages
-

+
+ - **faults-enabled** - enable or disable faults over netconf
+ - **call-home** - enable the NETCONF Call Home feature. If set to 'true', each simulated device, when booting up, will try to Call Home to the SDN Controller.
+- **ves** - container with settings for enabling or disabling VES features:
+
+ - **faults-enabled** - enable or disable faults over VES
+ - **pnf-registration** - enable PNF registration on start
+ - **heartbeat-period** - the number of seconds between VES heartbeat messages
+
+The **available-images** container has a list containing available (installed) simulations. The list corresponds (has the same name, and specific leafs) to the **network-function** list inside **simulation**, and the description is the same. This list is populated by the Manager at runtime after it checks which Docker images are pulled, including having multiple versions (both in tag and repository). To be more clear, each entry of this list is a possible simulation, and the list contains all the possible simulations. This allows the user to know the simulation capabilities of the Manager.
+
+There are 2 defined **notifications**:
+
+- **instance-changed** notification: is called by the manager whenever a change is done to any of the network functions. This contains data about the change:
+
+ - **change-status**: is a string which has the following structure: operation STATUS - info. operation can be *start*, *stop*, *mount*, *unmount*, *config* and *reconfig*; STATUS can be SUCCESS or FAILED; info can be present or not, depending on what further information is available about the change
+ - **function-type**: the function-type for the instance
+ - **name**: name of the instance that is changed
+ - **networking**: when starting and configuring an instance, this container has all the necessary networking data, such as IP and ports
+
+- **operation-status-changed** notification is called by the manager at the end of an operation:
+
+ - **status** returns the status of the operation: SUCCESS/FAILED. This status can also be statically read from the operational datastore under *nts-manager:simulation/last-operation-status*
+ - **error-mesage** an error message with details of the error (if any).
+
+Manager datastore changes mode of operation
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Changing any value from **sdn-controller** or **ves-endpoint** containers will be propagated to all running simulated network functions, and all new ones will use the values here. In the same manner, triggering any changes to the **fault-generation**, **netconf** and **ves** settings in a network function element from the *network-function* list will automatically propagate to all running network functions of the same *function-type*. However, changing the *docker-\** leafs of the *network-function* won't propagate, as they're only used as settings for starting new network functions.

All de details and mechanisms of the **network-function** container are explained in the **NTS Manager** section. Besides this container, there are also a couple of RPCs defined:
-* **datastore-random-populate** - calling this will trigger the network function to populate all its datastore with random data, and based on the *config.json* defined rules
-
-* **feature-control** - calling this will enable selected features. currently available features are:
-
- \* \*\*ves\-file\-ready\*\* \- enables VES file ready, and stats a FTP and a SFTP server on the network function
-
- \* \*\*ves\-heartbeat\*\* \- enabled VES heartbeat feature
-
- \* \*\*ves\-pnf\-registration\*\* \- enables VES PNF registration
-
- \* \*\*manual\-notification\-generation\*\* \- enables the manual notification generation feature
-
- \* \*\*netconf\-call\-home\*\* \- enables NETCONF's Call Home feature
+- **datastore-populate** - calling this will trigger the network function to populate all its datastores with data based on the *config.json* defined rules
+- **feature-control** - calling this will start or stop selected features. currently available features are (features marked with * can not be stopped once started):
- \* \*\*web\-cut\-through\*\* \- enables web cut through, adding the info to the ietf\-system module
+ - **ves-file-ready** - enables VES file ready, and stats a FTP and a SFTP server on the network function
+ - **ves-heartbeat** - enabled VES heartbeat feature
+ - **ves-pnf-registration*** - enables VES PNF registration
+ - **manual-notification-generation** - enables the manual notification generation feature
+ - **netconf-call-home*** - enables NETCONF's Call Home feature
+ - **web-cut-through** - enables web cut through, adding the info to the ietf-system module
-* **invoke-notification** - this RPC is used for forcing a simulated device to send a NETCONF notification, as defined by the user.
+- **invoke-notification** - this RPC is used for forcing a simulated device to send a NETCONF notification, as defined by the user:
- \- The \*\*input\*\* needed by the RPC:
+ - The **input** needed by the RPC:
+
+ - **notification-format** - can be either *json* or *xml*
+ - **notification-object** - this is a string containing the notification object that we are trying to send from the simulated device, in JSON format. **Please note that the user has the responsibility to ensure that the JSON object is valid, according to the definition of the notification in the YANG module.** There is no possibility to see what was wrong when trying to send an incorrect notification. The RPC will only respond with an "ERROR" status in that case, without further information. E.g. of a JSON containing a notification object of type ***otdr-scan-result*** defined in the ***org-openroadm-device*** YANG module: ***{"org-openroadm-device:otdr-scan-result":{"status":"Successful","status-message":"Scan result was successful","result-file":"/home/result-file.txt"}}***. **Please note that the notification object contains also the name of the YANG model defning it, as a namespace, as seen in the example.**
+ - The **output** returned by the RPC:
+
+ - **status** - if the notification was send successfully by the simulated device, the RPC will return a **SUCCESS** value. Else, the RPC will return a **ERROR** value.
- \- \*\*notification\-format\*\* \- can be either \*json\* or \*xml\*
+- **invoke-ves-pm-file-ready** - as name impiles, it invokes a file ready VES request, with a specified *file-location*
+- **clear-fault-counters** - clears all counters for the fault generation system. see **Fault generation** below.
- \- \*\*notification\-object\*\* \- this is a string containing the notification object that we are trying to send from the simulated device, in JSON format. \*\*Please note that the user has the responsibility to ensure that the JSON object is valid, according to the definition of the notification in the YANG module.\*\* There is no possibility to see what was wrong when trying to send an incorrect notification.

+It is worth mentioning that the *NTS Manager* also populates the `function-type` leaf of its own *nts-network-function* module with the value `NTS_FUNCTION_TYPE_MANAGER`. This is done to help users which are connected to a NETCONF server get the data from *nts-network-function* and immediatly see what they are connected to.
- \- The \*\*output\*\* returned by the RPC:
-
- \- \*\*status\*\* \- if the notification was send successfully by the simulated device, the RPC will return a \*\*SUCCESS\*\* value. Else, the RPC will return a \*\*ERROR\*\* value.

-### Network function operation
-==============================
-
-Under usual operation, the network functions are managed by the manager which will perform the operations listed below. However, if a user chooses to, it can manually start up a network function, and manage it via NETCONF (datastore and RPCs).

-### Fault generation
-====================
-Fault generation is controlled using a combination of JSON and YANG settings.
+Network function standalone operation
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-From the JSON perspective, the settings are as below:
+The network function can run in standalone mode when the **NTS_NF_STANDALONE_START_FEATURES** environment variable is not blank. The value found here determines the standalone operation, and it can be combined of two values:
+- datastore-populate, which populates the datastore by the rules
+- any bits of the feature-type YANG typedef (defined in nts-common.yang), which will enable the respective features.
-"alarm-rules" : {
+Other than this, the network-function will operate just as it would when started by the manager and it can be controller through the **nts-network-function.yang** interface.
- "yang\-notif\-template" : "<xml ... %%severity%% $$time$$ %%custom1%%>",
+Datastore random population
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^

-
- }
-
- ...
-
- {
-
- ...
-
- }
-
- ]
-
-}
-
-
-* **alarm-rules** node should be a main node in *config.json* for the respective network function in order for the fault generation to be enabled
-
- \* \*\*yang\-notif\-template\*\* \- template of the yang notification model in current network function. can be "" to disable notifications. must always be present

+ ]
+ }
+
+NOTE: pre-generated data must be in either JSON or XML format; be careful on how the file name is saved, because the simulator can only discover format based on filename (case-sensitve ".json" or ".xml")
+
+NOTE: when generating random data, the pre-generated data is loaded first, and any module affected by the pre-generated data is automatically excluded from random populating. The order in which data is added to the datastore is:
+
+1. pre-generated data
+2. random data
+
+NOTE: the order in which datastores are being populated:
+
+1. the RUNNING datastore
+2. the OPERATIONAL datastore
+
+Fault generation
+^^^^^^^^^^^^^^^^
+
+Fault generation is controlled using a combination of JSON and YANG settings. From the JSON perspective, the settings are as below:
+
+::
+
+ "fault-rules" : {
+ "yang-notif-template" : "<xml ... %%severity%% $$time$$ %%custom1%%>",
+ "choosing-method" : "random | linear",
+ "faults" : [
+ {

+ "specific-problem" : "",
+
+ //template custom fileds
+ "custom1" : "",
+ "custom2" : ""
+ }
+ ...
+ {
+ ...
+ }
+ ]
+ }
+
+ * **fault-rules** node should be a main node in *config.json* for the respective network function in order for the fault generation to be enabled
+ * **yang-notif-template** - template of the yang notification model in current network function. can be "" to disable notifications. must always be present
+ * **choosing-method** - method to choose the fault. can be either *linear* or *random*, and must always be present
+ * **faults** list of faults to choose from by "choosing-method". it can contain any number of fields, custom ones, along with the mandatory VES fields presented below:
+ * **condition**
+ * **object**
+ * **severity** - should correspond to VES defined: NORMAL, WARNING, MINOR, MAJOR, CRITICAL (case sensitive)
+ * **date-time**
+ * **specific-problem**
On the **yang-notif-template** and on any of the fields, there are two options for creating "dynamic" content (also see example above):
+- **variables** - any field put in between %% will be replaced with the field's value
+- **functions** - function names are put in between $$. Available functions are:
-* **variables** - any field put in between %% will be replaced with the field's value
-
-* **functions** - function names are put in between $$. Available functions are:
-
- \* \*\*time\*\* \- returns current timestamp in a YANG date\-time format
-
- \* \*\*uint8\_counter\*\* \- a unique 8\-bit counter, starting from 0, each time this function is found, the counter is automatically increased; when going above the max value, it will reset from 0
-
- \* \*\*uint16\_counter\*\* \- a unique 16\-bit counter, starting from 0, each time this function is found, the counter is automatically increased; when going above the max value, it will reset from 0
-
- \* \*\*uint32\_counter\*\* \- a unique 32\-bit counter, starting from 0, each time this function is found, the counter is automatically increased; when going above the max value, it will reset from 0
+ - **time** - returns current timestamp in a YANG date-time format
+ - **uint8_counter** - a unique 8-bit counter, starting from 0, each time this function is found, the counter is automatically increased; when going above the max value, it will reset from 0
+ - **uint16_counter** - a unique 16-bit counter, starting from 0, each time this function is found, the counter is automatically increased; when going above the max value, it will reset from 0
+ - **uint32_counter** - a unique 32-bit counter, starting from 0, each time this function is found, the counter is automatically increased; when going above the max value, it will reset from 0
It is worth to mention that the replacement is done within any field, of any field. This means that it is possible to have nested fields and functions. See example for better understanding.
From the YANG perspective, one can control whether faults are enabled or disabled independently via NETCONF and/or VES, through their respective containers described in the sections above. The YANG **fault-generation** container contains:
-* **fault-delay-list** - a list with elements which consists of *index* (unimportant, but needs to be unique) and *delay-period* which represents the number of seconds in between the current fault and the next fault. Please note that the fault is chosen from and based on the settings esablished in *config.json*
-
-* **fault-count** - the status of the faults encountered by the network function; it is not present in the manager's schema
+- **fault-delay-list** - a list with elements which consists of *index* (unimportant, but needs to be unique) and *delay-period* which represents the number of seconds in between the current fault and the next fault. Please note that the fault is chosen from and based on the settings esablished in *config.json*
+- **fault-count** - the status of the faults encountered by the network function; it is not present in the manager's schema
In order to clear the **fault-count** counters, on the **network-function** module there is a **clear-fault-counters** RPC which can be called via NETCONF.
-## NTS Application

+
+Supervisor functionality and configuration
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The NTS app tries to be very little dependent on other tools. Until v1.0.8 one of these tools was supervisord, and now its functionality is embedded inside the NTS app. Now the Docker image runs the NTS app with --supervisor parameter to start the supervisor. When supervisor is ran, other main modes and their options are unavailable for that instance (the supervisor will spawn another instance for the main functionalities). Configuration of the supervisor functionality is done via config.json:
+
+::
+
+ "supervisor-rules": {
+ "netopeer": {
+ "path": "/usr/local/bin/netopeer2-server",
+ "args": ["-d", "-v2"],
+ "autorestart": true,
+ "stdout": "log/netopeer-stdout.log",
+ "stderr": "log/netopeer-stderr.log"
+ },
+
+ "sshd": {
+ "path": "/usr/sbin/sshd",
+ "args": ["-D"],
+ "autorestart": true,
+ "stdout": "log/sshd-stdout.log",
+ "stderr": "log/sshd-stderr.log"
+ },
+
+ "ntsim-network-function": {
+ "path": "/opt/dev/ntsim-ng/ntsim-ng",
+ "args": ["-w/opt/dev/ntsim-ng", "-f"],
+ "nomanual": true,
+ "stdout": "",
+ "stderr": ""
+ }
+ }
+
+The example above is the default example for a network function. The *supervisor-rules* object contains a list of tasks to run, each with their own settings. Below is a description of all parameters:
+
+- path: *mandatory field* - full path to the the binary
+- args: a list of arguments to be passed to the binary, default is no arguments
+- autorestart: this is true or false, whether to autorestart the application on exit/kill, default is false
+- nomanual: when this is true, the task **won't** be automatically ran when the **NTS_MANUAL** environment variable is present. Default is false, and using this is usually good for debugging.
+- stdout and stderr: path to redirect stdout or stderr to; if **blank**, it will be replaced by **/dev/null** for discarding. If any of the fields are not present in configuration, default value will be used (actual stdout/stderr).
+
+Docker container initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The NTS app is responsible for initializing the Docker container upon build. What it actually does is described below:
1. Install modules located in the *deploy/yang/* folder recusively
-
- \- note that if a module requires startup data (mandatory data), this can be acheived by having an \*\*XML\*\* file with this data along the YANG file. For example, if, let's say \*ietf\-interfaces.yang\* would require startup date, there must be a \*ietf\-interfaces.xml\* located in the same folder.
-
+ - note that if a module requires startup data (mandatory data), this can be acheived by having an **XML** or a **JSON** file with this data along the YANG file. For example, if, let's say *ietf-interfaces.yang* would require startup date, there must be a *ietf-interfaces.xml* or *ietf-interfaces.json* located in the same folder.
2. Enable all YANG features of the modules, unless specifically excluded
-If the initialization failes, the result is returned to the Docker builder, so the build will fail, and user can see the output. Docker initialization can be customized from the *config.json* file, as described below. The example is self-expainatory, and the *docker-rules* node needs to be a main node of *config.json*:

-# Usage
-=======
-
-The NTS Manager can be used to start any type of simulated network function.
-
-## Building the images
-======================
+Building the images locally
+---------------------------
The `nts_build.sh` script should be used for building the docker images needed by the NTS to the local machine. This will create docker images for the Manager and for each type of simulated network function.
-The user can also directly use the already built docker images, that are pushed to the highstreet docker repository. This can be done by using the `nts*pull*highstreet_repo.sh` script, which will pull all the images locally.
+The user can also directly use the already built docker images, that are pushed to the nexus3 docker repository by the LF Jenkins Job. E.g.: *nexus3.o-ran-sc.org:10004/o-ran-sc/nts-ng-o-ran-du:1.2.0*
-## Starting the NTS Manager
-===========================
+Starting the NTS Manager
+------------------------
-The **nts-manager-ng** can be started using the docker-compose file in this repo. The file assumes that the docker images were pulled from the highstreet docker repository.
+The **nts-manager-ng** can be started using the docker-compose file in this repo. The file assumes that the docker images were built locally previously.
+::
-docker-compose up
+ docker-compose up -d ntsim-ng
Before starting, the user should set the environment variables defined in the docker-compose file according to his needs:
-* **NETCONF*NTS*HOST_IP**: an IP address from the host, which should be used by systems outside the local machine to address the simulators;
-
-* **NETCONF*NTS*HOST*BASE*PORT**: the port from where the allocation for the simulated network functions should start;
-
-* **IPv6Enabled**: should be set to `true` if IPv6 is enabled in the docker daemon and the user wants to use IPv6 to address the simulated network functions.

-# Release notes
-===============
-## version 1.0.3
-================
-- [fixed] fixed issues where ODL could not parse the correct versions for yang files
-
-## version 1.0.2
-================
-- [fixed] bug that occured when trying to start a wrong instance (bad docker-repository or docker-tag)
-- [fixed] when populating the fault-delay-list, if the sum of all the faults was 0, the network funciton kept on generating faults and crashed
+- **NTS_HOST_IP**: an IP address from the host, which should be used by systems outside the local machine to address the simulators;
+- **NTS_HOST_BASE_PORT**: the port from where the allocation for the simulated network functions should start, if not specified otherwise sepparately (see below); any port not defined will automatically be assigned to *BASE_PORT*; **NOTE** that in order for a port to be eligible, it must be greater than or equal to **1000**:
+
+ - **NTS_HOST_NETCONF_SSH_BASE_PORT**
+ - **NTS_HOST_NETCONF_TLS_BASE_PORT**
+ - **NTS_HOST_TRANSFER_FTP_BASE_PORT**
+ - **NTS_HOST_TRANSFER_SFTP_BASE_PORT**
-## version 1.0.1
-================
-- [feature-add] added web-cut-through feature
-- [fixed] mount-point-addressing-method was mistakenly changing after starting
+- **IPv6_ENABLED**: should be set to `true` if IPv6 is enabled in the docker daemon and the user wants to use IPv6 to address the simulated network functions.
-## version 1.0.0
-================
+In each simulated network-function the **docker-repository** leaf must be set accordingly (to the value: *o-ran-sc/*), because all the docker images that are being built locally have this prefix.
-Initial release.
+Starting standalone NFs
+-----------------------
+One could start 1 instance of a simulated O-RU-FH and 1 instance of a simulated O-DU by running the `nts-start.sh` script. Pre-configured values can be set in the `.env` file.
