this application provides the simple example of link aggregation using LACP. the module "lacplib" controls exchange of LACP packets and watches the status of the slave i/fs. the status changes if the i/fs went into a LAG or timeout to exchange LACP occurred. the module sends a "EventSlaveStateChanged" event when the status changed. the module "simple_switch_lacp" is a variation of "simple_switch". the switch receives the "EventPacketIn" event instead of the "EventOFPPacketIn" event from the module "lacplib" in order to except LACP. when the module received "EventSlaveStateChanged" event, the module resets flow entries. to run: ryu-manager ryu/app/simple_switch_lacp.py Signed-off-by: Yuichi Ito <ito.yuichi0@gmal.com> Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
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 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 ryuIf you prefer to install Ryu from the source code:
% git clone git://github.com/osrg/ryu.git
% cd ryu; python ./setup.py installIf 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 write your Ryu application, have a look at Writing ryu application document. After writing your application, just type:
% ryu-manager yourapp.pySupport
