What is ONOS?
ONOS stands for Open Network Operating System. ONOS provides the control plane for a software-defined network (SDN), managing network components, such as switches and links, and running software programs or modules to provide communication services to end hosts and neighboring networks. If you are familiar with server operating systems, you will find that ONOS provides some analogous types of functionality, including APIs and abstractions, resource allocation, and permissions, as well as user-facing software such as a CLI, a GUI, and system applications. If you are familiar with traditional "inside the box" switch operating systems, you will find that ONOS manages your entire network rather than a single device, which can dramatically simplify management, configuration, and deployment of new software, hardware and services. If you are familiar with SDN controllers, you should feel right at home because the ONOS platform and applications act as an extensible, modular, distributed SDN controller. <From ONOS wiki:https://wiki.onosproject.org/>
為了在本地獲得一個快捷的ONOS環境，我們可以采用官網封裝好的virtualbox 虛擬鏡像來快速部署ONOS環境。
http://onlab.vicci.org/onos/vm/onos-tutorial-1.0.0r161-ovf.zip
下邊開始安裝步驟的介紹：
1.下載當前版本的VirtualBox安裝包。鏈接：http://sw.bos.baidu.com/sw-search-sp/software/6bda11b7d3256/VirtualBox-5.1.30.18389-Win.exe
//推薦使用VirtualBox，因為相比於VMWare來說，一是：免費，二是：相對對物理機的資源消耗更少。
2.下載ONOS官網封裝好的ONOS zip包。鏈接：http://onlab.vicci.org/onos/vm/onos-tutorial-1.0.0r161-ovf.zip
//下載完成的zip文件解壓開來以后可以看到如下文件：onos-tutorial-1.0.0.ovf 和 onos-tutorial-1.0.0.vmdk //注意核實//
3.在VirtualBox中導入ONOS包onos-tutorial-1.0.0.ovf。
主要步驟截圖：
First Step：
2:瀏覽文件onos-tutorial-1.0.0.ovf進入VirtualBox。如下圖：
[首次安裝請保持所有選項默認]
點擊導入即可。
導入完成以后：
登錄虛擬機內的 Guest OS 帳號和密碼如下：
USERNAME:tutorial1
PASSWORD:tutorial1
打開以后界面如下：
打開以后雙擊快捷方式ONOS和Mininet來迅速啟動一個SDN的控制器ONOS和Mininet[An Instant Virtual Network on your Laptop (or other PC)]
本實驗所有的聯系都是使用相同的網絡拓撲 ( 如下圖所示 ) 。網絡中有 6 台交換機， 4 台外邊的交換機上連接了 6 台主機，這 4 台交換機又連接到中間互連
的 2 台交換機上。
打開ONOS的Gui之前還得做一個動作，來激活ONOS-GUI的feature：
在ONOS的CLI中安裝ONOS-GUI的feature。
ONOS>feature:install onos-gui
//這時候查看8181端口處於LISTEN狀態。//
雙擊桌面ONOS GUI快捷方式即可進入ONOS的圖形化界面。
關於Mininet添加交換機和host過程如下：

4.實現不同host之間的互訪，還得激活一個ONOS的feature Reactive Forwarding
在未激活該feature時候，做ping測試，發現：
mininet> h11 ping -c3 h41
PING 10.0.0.19 (10.0.0.19) 56(84) bytes of data.
From 10.0.0.1 icmp_seq=1 Destination Host Unreachable
From 10.0.0.1 icmp_seq=2 Destination Host Unreachable
From 10.0.0.1 icmp_seq=3 Destination Host Unreachable
--- 10.0.0.19 ping statistics ---
3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 2009ms
//同一網段的不同host之間竟然不通。//
"Reactive Forwarding" 是一個非常簡單的 SDN 應用程序，它為每一個被送到控制器的數據包安裝流表。但是此應用默認沒有被加載。使用如下命令查看已經被加載的應用程序列表：
這里順便看一下剛才就好的ONOS—GUI的feature：
onos> list | grep onos-gui
158 | Active | 80 | 1.0.0 | onos-gui
onos>
//激活Forwarding 的feature//
ONOS>feature:install onos-app-fwd
查看是否激活的該feature：
onos> list | grep fwd
152 | Active | 80 | 1.0.0 | onos-app-fwd //已經激活該feature//
onos>
此時在Mininet中做ping測試：
mininet> h11 ping h12
PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=10.2 ms
64 bytes from 10.0.0.2: icmp_seq=2 ttl=64 time=2.06 ms
^C
--- 10.0.0.2 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 2.069/6.183/10.297/4.114 ms
mininet>
//此時ping通//
此時做所有主機之間互ping測試：pingall
結果如下：
mininet> pingall

5.該方式安裝的ONOS本身集成了wireshark工具，如果需要使用到抓包分析的話，可以直接使用，非常方便。
順便提一下，該封裝的虛機默認使用的是NAT模式的網絡，如果對VirtualBox的幾種網絡類型熟悉的話，可以自己更改虛擬網卡的連接方式來實現一些便捷的功能。比如筆者在使用該方式安裝的時候就把網絡更改為橋接方式，[對於新手不建議做此操作]
更多操作請訪問：https://wiki.onosproject.org/display/ONOS/Application+tutorial
wireshak user guide：https://www.wireshark.org/docs/wsug_html_chunked/index.html
wireshark抓包附例。
注意：在虛機中使用wireshark要特別的注意，當抓包結束以后，別忘了stop抓包，否則可能會出現內存被沾滿而系統崩潰。
6.如有疑問可郵件聯系。
