Ncs-Netsim2

ncs-netsim is a great tool, but it lack of following features which are developed as part of ncs-netsim2

  • ncs-netsim2 features
    • delete-devices <device-names>
    • create-network-from [ yaml | json ] <filename>
    • create-device-from [ yaml | json ] <filename>
    • create-network-template [ yaml | json ]
    • create-device-template [ yaml | json ]

ncs-netsim2 is a wrapper on top of ncs-netsim with added features. It's written in python and we opened the space to add more features to it.

Introduction

ncs-netsim, It's a powerful tool to build a simulated network environment for Network Service Orchestrator (NSO) it's also called as NCS - NSO. In these network topologies we can test the network configurations based on the need as per the use case.

ncs-netsim2, An open space to automate the ncs-netsim.

Pre-requisites

  • ncs-netsim command must be reconginsed by the terminal.
  • ncs-netsim2 supports both trains of python 2.7+ and 3.1+, the OS should not matter.

Installation and Downloads

The best way to get ncs-netsim2 is with setuptools or pip. If you already have setuptools, you can install as usual:

python -m pip install ncs-netsim2

Otherwise download it from PyPi, extract it and run the setup.py script

python setup.py install

If you're Interested in the source, you can always pull from the github repo:

  • From github git clone https://github.com/kirankotari/ncs-netsim2.git

Create Network/Device Template

Template to automate the Network/Device creation process.

⋊> ~/k/i/ncs-netsim2 on master ◦ ncs-netsim2 create-network-template [yaml | json]
⋊> ~/k/i/ncs-netsim2 on master ◦ ncs-netsim2 create-device-template [yaml | json]

which gives template.json/yaml file where you can update the files based on your need/requirement.

Create Network/Device From Template

We are using the templates which are updated based on your requirement

⋊> ~/k/i/ncs-netsim2 on master ◦ ncs-netsim2 create-network-from [yaml | json] <filename>
⋊> ~/k/i/ncs-netsim2 on master ◦ ncs-netsim2 create-device-from [yaml | json] <filename>

How to choose the Templates and How they look

These templates follows the same process of ncs-netsim, format is your choice

  1. prefix based creation - ncs-netsim2 create-network-template yaml
  2. name based creation - ncs-netsim2 create-device-template yaml

Note:- So far we are not supporting combinations.

You can find the examples in the same directory start with template-create-<...>.yaml/json.

and defaults to ./netsim, any netsim directory above in the path,
or $NETSIM_DIR if set.

FAQ

  • Question: Do I need to install ncs-netsim too?
    Answer: Not really, ncs-netsim tool comes along with NSO. If you are working with NSO it's won't be a problem.

  • Question: Is python mandatory for ncs-netsim2?
    Answer: Yes, the library is written in python and we wanted not to be dependend on NSO versions.

  • Question: Is ncs-netsim2 backword compatable?
    Answer: We recommend to use ncs-netsim2 commands instead of ncs-netsim. However couple of commands are still backward compatable ie. ncs-netsim list, etc.

  • Question: I am seeing following error ./env.sh: line 12: export: `Fusion.app/Contents/Public:/Applications/Wireshark.app/Contents/MacOS': not a valid identifier
    Answer: We recommend to check your env path as recommended in following link
