Service Function Chaining

Service Function Chaining
=========================

Service Function Chaining provides the ability to define an ordered list of a
network services (e.g. firewalls, load balancers). These service are then
"stitched" together in the network to create a service chain. This project
provides the infrastructure (chaining logic, APIs) needed for ODL to provision
a service chain in the network and an end-user application for defining such
chains.

Instalation
===========

The installation has been tested on Ubuntu Linux.

1.- SFC needs to have Python 3.4 installed
2.- openssl-devel MUST BE INSTALLED as it is pip dependency
sudo apt-get install libssl-dev openssl

3.- Before you run installation from Pypi,
be sure you have installed libnetfilter-queue.
To run installation of libnetfilter-queue:
sudo apt-get install libnetfilter-queue-dev

4.- be sure you have installed pip3
to run installation of pip3 :
sudo apt-get install python3-pip

5.- Finally the installation of the SFC package:
sudo pip3 install sfc

All other dependencies are handled in the SFC setup.

There is still possibility to download
the sfc-xxx.tar.gz file from Pypi repository,
unzip it , locate setup.py file and use the python installer
python3 setup.py install


Usage
=======

python3.4 sfc_agent --rest --nfq-class --odl-get-sff --ovs-sff-cp-ip <local SFF IP dataplane address> --odl-ip-port=<ODL REST IP:port> --sff-name=<my SFF name>--sff-os=<agent os> --agent-port=<agent listening port>

note:
root privileges are required if `--nfq-class` flag is used

SFC Agent

optional arguments:
-h, --help show this help message and exit
--odl-get-sff Get SFF from ODL
--auto-sff-name Automatically get SFF name
--nfq-class Flag to use NFQ Classifier
-r, --rest Flag to use REST
--sff-name SFF_NAME Set SFF name
--odl-ip-port ODL_IP_PORT
Set ODL IP and port in form <IP>:<PORT>. Default is
localhost:8181
--ovs-sff-cp-ip OVS_SFF_CP_IP
Set local SFF Open vSwitch IP. Default is 0.0.0.0
--sff-os {XE,XR,OVS} Set SFF switch OS
--agent-port AGENT_PORT
Set SFC Agent port. Default is 5000

Example
=======
sudo python3.4 sfc_agent.py --rest --odl-ip-port 192.168.33.11:8181 --auto-sff-name --nfq-class

this command will run the sfc_agent using REST, trying to recognize its own SFF name and running
also NFQ classifier instance.
