ICOA全称：Inter Controller Coorperation ONOS Application
以东西向协议OXP作为支持在ONOS上开发APP，支持异构控制器之间通过OXP进行跨SDN域的协同工作。修改了部分ONOS源码，在后期优化中，逐渐消除对ONOS源码的修改，尽量作为一个独立的APP.
ONOS is a new SDN network operating system designed for high availability, performance, scale-out.
- High availability through clustering and distributed state management.
- Scalability through clustering and sharding of network device control.
- Performance that is good for a first release, and which has an architecture that will continue to support improvements.
- Northbound abstractions for a global network view, network graph, and application intents.
- Pluggable southbound for support of OpenFlow and new or legacy protocols.
- Graphical user interface to view multi-layer topologies and inspect elements of the topology.
- REST API for access to Northbound abstractions as well as CLI commands.
- CLI for debugging.
- Support for both proactive and reactive flow setup.
- SDN-IP application to support interworking with traditional IP networks controlled by distributed routing protocols such as BGP.
- IP-Optical use case demonstration.

git clone https://github.com/paradisecr/ONOS-ICOA.git
mv ONOS-ICOA onos
git checkout v2
方法一：使用ONOS自带脚本安装
cd onos
./tools/dev/bin/onos-setup-ubuntu-devenv
方法二： 手动安装依赖，参照ONOS wiki
vim ~/.profile
在末尾追加内容:
. ~/onos/tools/dev/bash_profile
使环境变量生效：
source ~/.profile
为使编译顺利，推荐使用国内Maven镜像源。
一种可选的做法(使用阿里云Maven镜像,代替central镜像)：在maven的settings.xml 文件里配置mirrors的子节点，添加如下mirror:
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>central</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
编译ONOS源码, 耐心等待安装完成即可：
cd ~/onos
mvn clean install -DskipTests
等待安装完成：

编译可能会遇到的错误：
1. /usr/lib/jvm/jdk1.8.0_112/jre/lib/amd64/libawt_xawt.so: libXrender.so.1: cannot open shared object file: No such file or directory
当运行环境为server版本时，缺少图形库。安装必要的图形库即可。
网上推荐的方法(未测试)：http://www.th7.cn/Program/java/201612/1054332.shtml
我的方法(投机取巧，安装ubuntu的图形化记事本gedit，它会帮忙安装所有图形库依赖)：sudo apt install gedit
ok clean
