1 [![Build Status](http://jenkins.sonata-nfv.eu/buildStatus/icon?job=son-emu)](http://jenkins.sonata-nfv.eu/job/son-emu)
4 This is the repository of [SONATA's](http://sonata-nfv.eu) emulation platform.
6 This emulation platform was created to support network service developers to locally prototype and test complete network service chains in realistic end-to-end multi-PoP scenarios. It allows the direct execution of real network functions, packaged as Docker containers, in emulated network topologies running locally on the network service developer's machine.
8 More details about the the emulator's architecture and concepts can be found in the following publication(s):
10 * Manuel Peuster, Holger Karl, and Steven van Rossem. ["MeDICINE: Rapid Prototyping of Production-Ready Network Services in Multi-PoP Environments."](http://arxiv.org/abs/1606.05995) pre-print arXiv:1606.05995 (2016).

70 Contributing to the son-emu is really easy. You must:
72 1. Clone [this repository](http://github.com/sonata-nfv/son-emu);
73 2. Work on your proposed changes, preferably through submiting [issues](https://github.com/sonata-nfv/son-emu/issues);
74 3. Submit a Pull Request;
75 4. Follow/answer related [issues](https://github.com/sonata-nfv/son-emu/issues) (see Feedback-Chanel, below).
78 There are two ways to install and use son-emu. The simple one is to use Vagrant to create a VirtualBox-based VM on you machine that contains the pre-installed and configured emulator. The more complicated installation requires a freshly installed Ubuntu 14.04 LTS or 16.04 LTS and is done by a ansible playbook.
80 ### Vagrant Installation
82 * Request VirtualBox and Vagrant to be installed on the system.
83 * `git clone https://github.com/sonata-nfv/son-emu.git`
86 * `vagrant ssh` to enter the new VM in which the emulator is installed.
88 Follow the MOTD in the VM to run the example topology and the dummy-gatekeeper. The dummy-gatekeeper's default port 5000 is forwarded to the host machine and can be accessed from it by using, e.g., curl http://127.0.0.1:5000/packages.
90 ### Ansible Installation
92 * Requires: Ubuntu 14.04 LTS or 16.04 LTS
93 * `sudo apt-get install ansible git`
94 * `sudo vim /etc/ansible/hosts`
95 * Add: `localhost ansible_connection=local`
100 * `git clone https://github.com/mpeuster/containernet.git`
101 * `cd ~/containernet/ansible`
102 * `sudo ansible-playbook install.yml`
103 * Wait (and have a coffee) ...
108 * `git clone https://github.com/sonata-nfv/son-emu.git`
109 * `cd ~/son-emu/ansible`
110 * `sudo ansible-playbook install.yml`
115 #### Manual Usage Example:
117 This simple example shows how to start the emulator with a simple topology (terminal 1) and how to start (terminal 2) some empty VNF containers in the emulated datacenters (PoPs) by using the son-emu-cli.
119 * First terminal (start the emulation platform):
120 * `sudo python src/emuvim/examples/simple_topology.py`
122 * `son-emu-cli compute start -d datacenter1 -n vnf1`
123 * `son-emu-cli compute start -d datacenter1 -n vnf2`
124 * `son-emu-cli compute list`
126 * `containernet> vnf1 ifconfig`
127 * `containernet> vnf1 ping -c 2 vnf2`
129 #### Dummy Gatekeeper Example:
131 This example shows how to deploy a SONATA example package in the emulator using the dummy gatekeeper.
133 * First terminal (start the emulation platform):
134 * `sudo python src/emuvim/examples/sonata_y1_demo_topology_1.py`
135 * Second terminal (deploy the example package):
136 * Upload: `curl -i -X POST -F package=@sonata-demo-docker.son http://127.0.0.1:5000/packages`
137 * Instantiate: `curl -X POST http://127.0.0.1:5000/instantiations -d "{}"`
138 * Verify that service runs: `son-emu-cli compute list`
140 Note: The [son-push](https://github.com/mpeuster/son-cli) tool can be used instead of CURL.
