FUJITA Tomonori 323610d21f nxm: fix nxm to OFPMatch conversion 
This fixes a bug that the conversion ignores dl_dst.

Soheil Hassas Yeganeh reported a problem about simple_isolation:

The problem is that the isolation service tries to install
flow-entries for a specific src and dst (in
SimpleIsolation._modflow_and_send_packet), but instead the nx match
code installs flow-entries only with src addresses and ignores the
dst.  So, when I boot multiple vms, only one of them is reachable.

For instance, assume that you have two VM's A and B. When a packet
comes from the gw to A, it installs "gw->A: A's port", but the acutal
installed rule is "gw: A's port". This works for A, but, when you boot
B, it tries to install "gw->B: B's port", but the acutal rule to be
installed is "gw: B's port".  So, it always connect the gateway to
only one VM at a time.

Ryu Network Operating System

What's Ryu

Ryu is an Operating System for Software Defined Networking.

Ryu aims to provide a logically centralized control and well defined API that make it easy for operators to create new network management and control applications. Currently, Ryu manages network devices by using OpenFlow. You can say that Ryu is an OpenFlow Controller, which support OpenFlow v1.0, v1.2, and Nicira Extensions.

All of the code is freely available under the Apache 2.0 license. Ryu is fully written in Python.

Quick Start

Installing Ryu is quite easy:

% pip install ryu

If you prefer to install Ryu from the source code:

% git clone git://github.com/osrg/ryu.git
% cd ryu; python ./setup.py install

If you want to use Ryu with OpenStack, please refer detailed documents. You can create tens of thousands of isolated virtual networks without using VLAN. The Ryu application is included in OpenStack mainline as of Essex release.

If you want to run your Ryu application, have a look at a simple example. After writing your application, just type:

% ryu-manager yourapp.py

Support
