Currently, the matches of flows in the learning switch examples are based on the destination and the in_port. In a multi-OF-switch environment this could cause issues when doing calls from a host on a first switch to multiple hosts on another switch, namely that new destinations aren't added as a flow because the source is already known on the second switch (when doing multiple calls to different hosts on another switch). This patch fixes this issue by adding the eth_src to the match field. Reported-by: Jerico Moeyersons <jerico09@hotmail.com>
What's Ryu
Ryu is a component-based software defined networking framework.
Ryu provides software components with well defined API that make it easy for developers to create new network management and control applications. Ryu supports various protocols for managing network devices, such as OpenFlow, Netconf, OF-config, etc. About OpenFlow, Ryu supports fully 1.0, 1.2, 1.3, 1.4, 1.5 and Nicira Extensions.

Quick Start
Installing Ryu is quite easy:
% pip install ryuIf you prefer to install Ryu from the source code:
% git clone git://github.com/osrg/ryu.git
% cd ryu; pip install .If you want to write your Ryu application, have a look at Writing ryu application document. After writing your application, just type:
% ryu-manager yourapp.pyOptional Requirements
Some functionalities of ryu requires extra packages:
- OF-Config requires lxml and ncclient
- NETCONF requires paramiko
- BGP speaker (SSH console) requires paramiko
- Zebra protocol service (database) requires SQLAlchemy
If you want to use the functionalities, please install requirements:
% pip install -r tools/optional-requiresPlease refer to tools/optional-requires for details.
Prerequisites
If you got some error messages at installation step, please confirm dependencies for building required Python packages.
