ns3-gym - The Playground for Reinforcement Learning in Networking Research

ns3-gym

OpenAI Gym is a toolkit for reinforcement learning (RL) widely used in research. The network simulator ns-3 is the de-facto standard for academic and industry studies in the areas of networking protocols and communication technologies. ns3-gym is a framework that integrates both OpenAI Gym and ns-3 in order to encourage usage of RL in networking research.

Installation

1. Install all required dependencies required by ns-3.

# minimal requirements for C++:
apt-get install gcc g++ python3 python3-pip cmake

Check ns-3 requirements

2. Install ZMQ, Protocol Buffers and pkg-config libs:

sudo apt-get update
apt-get install libzmq5 libzmq3-dev
apt-get install libprotobuf-dev
apt-get install protobuf-compiler
apt-get install pkg-config

3. Clone ns3-gym repository in to contrib directory and change the branch:

cd ./contrib
git clone https://github.com/tkn-tub/ns3-gym.git ./opengym
cd opengym/
git checkout app-ns-3.36+

Check working with cmake

It is important to use the opengym as the name of the ns3-gym app directory.

3. Configure and build ns-3 project:

./ns3 configure --enable-examples
./ns3 build

Note: Opengym Protocol Buffer messages (C++ and Python) are build during configure.

4. Install ns3gym located in model/ns3gym (Python3 required)

cd ./contrib/opengym/
pip3 install --user ./model/ns3gym

5. (Optional) Install all libraries required by your agent (like tensorflow, keras, etc.).

6. Run example:

cd ./contrib/opengym/examples/opengym/ 
./simple_test.py

7. (Optional) Start ns-3 simulation script and Gym agent separately in two terminals (useful for debugging):

# Terminal 1
./ns3 run "opengym"

# Terminal 2
cd ./contrib/opengym/examples/opengym/ 
./test.py --start=0

Examples

All examples can be found here.

Basic Interface

1. Example Python script. Note, that gym.make('ns3-v0') starts ns-3 simulation script located in current working directory.

import gym
import ns3gym
import MyAgent
from ns3gym import ns3env

#env = gym.make('ns3-v0')  <--- causes some errors with the new OpenAI Gym framework, please use ns3env.Ns3Env()
env = ns3env.Ns3Env()
obs = env.reset()
agent = MyAgent.Agent()

while True:
  action = agent.get_action(obs)
  obs, reward, done, info = env.step(action)

  if done:
    break
env.close()

2. Any ns-3 simulation script can be used as a Gym environment. This requires only to instantiate OpenGymInterface and implement the ns3-gym C++ interface consisting of the following functions:

Ptr<OpenGymSpace> GetObservationSpace();
Ptr<OpenGymSpace> GetActionSpace();
Ptr<OpenGymDataContainer> GetObservation();
float GetReward();
bool GetGameOver();
std::string GetExtraInfo();
bool ExecuteActions(Ptr<OpenGymDataContainer> action);

Note, that the generic ns3-gym interface allows to observe any variable or parameter in a simulation.

A more detailed description can be found in our Paper.

Cognitive Radio

We consider the problem of radio channel selection in a wireless multi-channel environment, e.g. 802.11 networks with external interference. The objective of the agent is to select for the next time slot a channel free of interference. We consider a simple illustrative example where the external interference follows a periodic pattern, i.e. sweeping over all channels one to four in the same order as shown in the table.

We created such a scenario in ns-3 using existing functionality from ns-3, i.e. interference created using WaveformGenerator class and sensing performed using SpectrumAnalyzer class.

Such a periodic interferer can be easily learned by an RL-agent so that based on the current observation of the occupation on each channel in a given time slot the correct channel can be determined for the next time slot avoiding any collision with the interferer.

Our proposed RL mapping is:

• observation - occupation on each channel in the current time slot, i.e. wideband-sensing,
• actions - set the channel to be used for the next time slot,
• reward - +1 in case of no collision with interferer; otherwise -1,
• gameover - if more than three collisions happened during the last ten time-slots

The figure below shows the learning performance when using a simple neural network with fully connected input and an output layer. We see that after around 80 episodes the agent is able to perfectly predict the next channel state from the current observation hence avoiding any collision with the interference.

The full source code of the example can be found here.

Note, that in a more realistic scenario the simple waveform generator in this example can be replaced by a real wireless technology like LTE unlicensed (LTE-U).

RL-TCP

The proper RL-TCP agent example is still under development. However, we have already implemented and released two versions (i.e. time and event-based) of an interface allowing to monitor parameters of a TCP instance and control its Congestion Window and Slow Start Threshold -- see details here. Note, that both versions inherits from TcpCongestionOps and hence can be used as an argument for ns3::TcpL4Protocol::SocketType.

Moreover, using the event-based interface, we already have an example Python Gym agent that implements TCP NewReno and communicates with the ns-3 simulation process using ns3gym -- see here. The example can be used as a starting point to implement an RL-based TCP congestion control algorithms.

In order to run it, please execute:

cd ./contrib/opengym/examples/rl-tcp/
./test_tcp.py

Or in two terminals:

# Terminal 1:
./ns3 run "rl-tcp --transport_prot=TcpRl"

# Terminal 2:
cd ./contrib/opengym/examples/rl-tcp/
./test_tcp.py --start=0

Note, that our Python TCP NewReno implementation achieves the same number of transmitted packets like the one implemented in ns3 (see the output of ns-3 simulation, i.e. RxPkts: 5367 in both cases). Please execute the following command to cross-check:

./ns3 run "rl-tcp --transport_prot=TcpNewReno"

How to implement RSVP protocol?

Recently, I have been studying various commonly used protocol emulation. May I ask if NS3 can realize RSVP protocol emulation? I have not seen anyone realize RSVP on the Internet, so I have a skeptical attitude about the feasibility.

Time-based Interface Between Environment and Agent

Hi,

I have been experimenting on the test_tcp.py using a time-based interface between environment and agent. I set the tcpEnvTimeStep = 0.1 sec in sim.cc to execute the action from an agent and then send the state information to agent after every 0.1 seconds. The obtained output is out of synchronization and seems like the agent and simulations environment are updating values at different times. For example, this is the output for first 10 step calls which prints episode, step, state of 16 elements, reward, done, info:

Episode:  0  step:  1 [1, 1, 363241, 2, 4294967295, 340, 340, 0, 0, 0, 0, 0, 180000, 0, 0, 0] 0.0 False {}
----------------------------------------------------------------------------------------
Episode:  0  step:  2 [1, 1, 463241, 2, 4294967295, 341, 340, 0, 0, 0, 0, 0, 180000, 182571, 0, 0] 0.0 False {}

----------------------------------------------------------------------------------------
Episode:  0  step:  9 [1, 1, 1163241, 2, 4294967295, 343, 340, 340, 340, 1, 1, 227755, 180000, 382528, 382528, 3400] 0.0 False {}

On each time step I am increasing the 6th element in the state by 1, but it's not showing up like that. Can someone please explain what can be the probable reason for this desynchronization? When I set the tcpEnvTimeStep = 1 or higher, it works fine.

Difference between TimeBasedTcp and EventBasedTcp in example/rltcp?

Still can not figure out differences between TimeBasedTcp and EventBasedTcp in example/rltcp, which seems no materials I can refer to?

How to add bbr to ns3-gym ?

https://github.com/mark-claypool/bbr this repo works for ns3. How do I patch it to NS3-Gym?

waf directory dependency

The directory where I run the gym environment is hard encoded into the waf command. Is it possible to wrap the environment in a way that it can be invoked from any directory?

Validation of results from test_tcp.py in ns3-gym

Dear @pgawlowicz and ns3-gym team,

Just a question and some echos. After successfully running the test_tcp.py, I collected the results from the actions and observation and got the part of the table below to represent TCP-NewReno

stepIdx	Act_new_cWnd	Act_new_ssThresh	Obs_cWnd	Obs_ssThresh	Info	bytesInFlight	segmentSize	segmentsAcked
1	1	18552368	340	4294967295	CwndEvent	37104736	340	0
2	1	18552368	340	4294967295	CongestionStateSet	37718224	340	0
3	1	18859112	340	4294967295	CwndEvent	37718224	340	0
4	1	18859112	340	4294967295	PktsAcked	37104736	340	1
5	680	18552368	340	4294967295	IncreaseWindow	37104736	340	1

CSV flie Here

Regarding to existing TCP-NewReno in ns-2/ns-3, we shall be able to plot the x = ['simulate time (mms)'], y = ['cwnd'] as below fig in ns-2/ns-3

Since the results we got for the y-axis is the 'stepIdx' instead of the 'time'

As the potential Benchmark for adaptive/learning-based network simulator, is it possible to get the time parameters to compare the existing results as NewReno in ns3-gym? Otherwise, it is still a bit hard to validate the future rl-algorithms on the ns3-gym testbed with existing results in ns-2/ns-3.

Again many thanks for your amazing works on this research project, :)

gym.make('ns3-v0') fail!

Can you offer some example code?

Hi:
Thanks for your excellent work.
I am a new to ns3 and RL.I am doing some job on RL in TCP congestion control. But I found that the reward of TCPRL seems not be defined.
Can you offer some example code about TCLRL?
Best wishes

build failed, fatal error: ns3/opengym-module.h

when I build ns3-gym by the ./waf build, I get an error like:
In file included from ../scratch/linear-mesh-2/mygym.cc:21:0: ../scratch/linear-mesh-2/mygym.h:26:32: fatal error: ns3/opengym-module.h: No such file or directory compilation terminated. Waf: Leaving directory '/home/wangs0622/ns_3_workspace/ns3-gym/build' Build failed -> task in 'linear-mesh-2' failed with exit status 1 (run with -v to display more information)

And I found the opengym-module.h is used by many files in scratch directory. But the opengym-module.h is not existed in the build/ns/ directory. So I think the error reason is that I don't have the opengym-module.h file.

How to deal with it? and where can I get this header file? Thank you~

Is it possible to run environment and agent on different PCs?

Hello.

My name is Fabián and I am doing my Master's thesis on robust optimization of Wi-Fi networks configuration. First of all, I wanted to thank you and congratulate you for the great contribution that ns3-gym is to the investigation of these topics.

From the readme it is clear to me that it is possible to run the environment (simulation ns-3) and the agent (Python code) on separate terminals. But is it possible to do this on separate PCs? This is because I would like to train the agent on Google Colab, while keeping the network simulator on my PC.

Thank you very much in advance.
Kind regards.

Fabián.

problem in multi-agent "TypeError: 10 has type numpy uint 64, but expected one of : int"

Just a question and some echos. After successfully running the agent1.py, I got this error:

How can I correct it?

Again many thanks for your amazing works on this research project, :)

Error: No module named 'ns3gym.messages_pb2'

Dear ns3-gym team,

really nice work, but I bumped into a problem when I try
$ env = gym.make('ns3-v0')

import ns3gym.messages_pb2 as pb

ModuleNotFoundError: No module named 'ns3gym.messages_pb2'
with these error messages and could not empower the env any further.

I guess the messages_pd2 is this one below, but don't know where shall it be put.
https://github.com/grpc/grpc/blob/master/test/http2_test/messages_pb2.py

Any suggestion? noted I clone the ns3-gym with the version and followed your read.me just today - 10/22. Cheers

But I have upgrade to the latest protobuf manually and run ./waf clean each time before I run ./waf configure.

here is my ./waf configure output,

Waiting for simulation script to connect

Hi,

Many thanks for the ns3gym work, very timely.

I am having problem running the examples in the scratch folder. I am
constantly getting a message like “Waiting for simulation script to
connect” then the ns3 does notting afterwards.

I am using Ubuntu16.4 with python3.5 over a virtualenv instance.
I am running examples as follows: ./was --run "rl-tcp" (for example)
The same is true when running test files.

Any clue why I am entering such a condition.

Cheers,
Morteza

Nothing output when running"test_tcp.py"

I install successfully on Ubuntu,but when I run "test_tcp.py",nothing shows in my terminal.

Applying ns3-gym to multiple nodes

Hello, initially congratulations for the project!

I'm a master's student and I'm developing a project that aims to improve the AODV protocol using machine learning. I would like to know if it is possible to use the ns3-gym module in the AODV protocol, where when defining it as a routing protocol for the network, each node will have an individual instance of ns3-gym. I would like each node in the network to be able to manage their own variables to control their AODV instance using their own neural network, is this possible with ns3-gym? Would you have any example of how this can be done (multiple instances of ns3-gym in parallel)?

Work on MAC os

First, thanks for the excellent project. To make it work on MAC OS, please see my solutions on my fork.

some problem in ./waf build

I meet some problem in ./waf build, like following, does anyone help me? Thanks a lot.

How to add the the STA-ID in the MonitorSniffRx

Hello,

Is it possible to add the Id from the station in the MonitorSniffRx callback?
This way, for instance, in the use case wifi-spectrum-per-example.cc, one can use several station nodes and allocate the global variables for each one of them if the Id is known.

Thank you very much in advance.
Kind regards.

Guilherme.

Always pause at place “Got new port for ns3gm interface： ”

Some problems occurred during the installation process

when i run the example ./simple_test.py, it Remind me that I need to install a lot of modules。so can you give a more detail installation tutorial.

Undefined Reference to google::protobuf

I have installed all of the dependencies etc. as stated in the installation instructions at https://apps.nsnam.org/app/ns3-gym/, but when I build ns3, ns3-gym with examples enabled I receive the following error:

contrib/opengym/examples/opengym/sim.cc.1.o: In function google::protobuf::Arena::AllocHook(std::type_info const*, unsigned long) const': /usr/local/include/google/protobuf/arena.h:644: undefined reference to google::protobuf::Arena::OnArenaAllocation(std::type_info const*, unsigned long) const'

This is just the first in a long line of errors that provide the same info: undefined reference to google::protobuf.

I have tried removing different versions of protobuf from /usr and /usr/local, but that has not resolved this issue.

Fix use of ZMQ's deprecated send() and recv() functions

There is a compilation warning triggered by the use of the ZMQ's send() and recv() deprecated functions. Since most compilers now treat warnings as errors, this issue does not allow the compilation of the ns3-gym module.

ns3-gym installation issues about I can't find the 'opengym.h'

Dear author,When I was learning ns3gym, I encountered some problems.

First, I ran
sudo. /waf clean

and then I ran
sudo. / waf-d debug --enable-example --enable-tests configure

and then ran
sudo. /waf
and the following errors occurred:

**../src/opengym/test/opengym-test-suite.cc:4:25: fatal error: ns3/opengym.h: No such file or directory
compilation terminated.

Waf: Leaving directory `/home/zst/cheryl/ns3-gym/ns-allinone-3.26/ns3-gym-master/build'
Build failed
-> task in 'ns3-opengym-test' failed with exit status 1 (run with -v to display more information)**

I want to find the 'opengym.h',but I failed,can you tell me how to deal with this problem?

ZMQError: Operation cannot be accomplished in current state

Hi Piotr,
Hope you are doing fine.

Based on the cognitive-agent example, I did some simple changes to the code using q-learning for the training. When running training the code gets stuck at env.step(action) and the ZMQ socket error occurs. What can I do to fix this issue?
Seems like this issue is related to the Gameover condition.

Is it ok to change the Gameover condition?

ns 3 and openai

hello!! please i want to know if we must install ns3 and then, install openAi or we must download ns3 and ns3-gym paquages and then run the ./waf build?

How to update ns-3 version?

Hello!
As far as I know, the latest ns-3 version 3.34 already supports bbr-congestion. How should I update the ns-3 version in ns3-gym?
Thank you so much!

Basic example for connnecting ns3-gym with stable-baselines

It would be very convenient to be able to use stable-baselines out of the box on the gym-esque environments in this project. Although the environment's API access mirrors OpenAI's gym, under the hood there are discrepancies that prevent integration with stable-baselines as is.

ns3-gym Building Error

Hi anyone,

I'm trying to build the ns3-gym module following these two guides:

ns3-gym speed-up

This is not a bug per-say, but I noticed the following.
By decreasing the TimeStep for the simulation from 1 sec to 0.1sec, the simulation sped up by an order of ten easily. How is this behavior explained ? Is it related to how ZeroMQ batches messages ?

How about distribute the `ns3gym` as a python package on PyPI?

How about distributing the ns3gym as a python package on PyPI, so that we can run ns3 and python script on different machines?

Build of protobuf failed using ns3-mmwave stand alone module

I'm using NS3 stand-alone version - mmwave with IAB feature, that based on ns3 v3.29 and I'm trying to install and build ns3gym but I'm getting the error:

opengym/model/: warning: directory does not exist.
Could not make proto path relative: opengym/model/messages.proto: No such file or directory
Build of ns3gym Protobuf messages failed

I did all the prerequisites installations that needed.

what Should I do?

thanks!

I can't change nodeNum where I run the example of qlearn.py

When I change the nodeNum in the code,I get nothing but this

My environment is :Ubuntu 16.04 and Python3
Thanks very much

ns3-gym installation issues on macOS Mojave (ns3/opengym-module.h file not found)

I seem to get some weird ./waf build errors (ns3/opengym-module.h file not found) while trying to install ns3-gym on macOS Mojave 10.14.5.

I ran configure with:
./waf configure --disable-werror --enable-examples --enable-tests

And then did:
./waf build

which gave the following errors. I don't seem to have the "opengym-module.h" file anywhere in the source code. Is that file auto-generated, or can I download it from somewhere?

I've Python 3.6.4, and also installed both protobuf (libprotoc 3.6.0) and zmq (zeromq 4.3.2).

Any help would be much appreciated.

Performance

Do you have some advice to make the interface faster?

python socket recv hanging

I wrote a custom environment following your examples. When running training, sometimes the code will get stuck at env.step(action). From the keyboard interrupt, it seems like an issue with the zmq socket? Is there a way to resolve this so that the training does not get stuck?
