L2 Switch架构

L2 Switch项目包含以下几个部分：

Packet Handler (包处理) ：对发往控制器的数据包进行解析并将数据包正确地转发
Loop Remover (环路消除) ：消除网络链路中的环路
Arp Handler (ARP处理) ：解析并处理ARP数据包
Address Tracker (地址跟踪) ：学习网络中的MAC或IP
Host Tracker (主机跟踪) ：跟踪网络中的主机位置
L2 Switch Main (二层交换主要部件) ：根据网络流量对每一个交换机下发流表

安装L2Switch模块

进入karaf控制台，进行以下的指令安装：

opendaylight-user@root>feature:install odl-l2switch-all

odl-l2switch-all包含以下几个模块：

odl-l2switch-switch
odl-l2switch-switch-rest
odl-l2switch-switch-ui
odl-l2switch-hosttracker
odl-l2switch-addresstracker
odl-l2switch-arphandler
odl-l2switch-loopremover
odl-l2switch-packethandler

功能体验

使用Mininet创建拓扑

Mininet虚拟机参数：

HostName:mininet-vm1
CPU: 2核
RAM: 4GB
IP1：10.0.3.101(Public Network)
IP2: 172.16.3.101(SDN Network)

在mininet-vm1中创建包含3个交换机,每台交换机各连1台主机的拓扑,并产生网络流量(Ping)：

mininet@mininet-vm1:~$ sudo mn --controller=remote,ip=10.0.3.100 --mac --topo=linear,3 --switch ovsk,protocols=OpenFlow13
mininet> pingall

此时在ODL的控制页面中的Topology标签中可以看到网络拓扑。

地址学习检测

在本地使用Rest调试工具（如Opera的RestMan）往ODL控制器发送以下Rest请求，按提示输入用户名(admin)和密码(admin)后，可以查看第一个交换机第一个端口所学习到的MAC和IP地址。

http://10.0.3.100:8181/restconf/operational/opendaylight-inventory:nodes/node/openflow:1/node-connector/openflow:1:1

可以看到响应部分的内容：

{"node-connector": [{"id": "openflow:1:1","flow-node-inventory:state": {"link-down": false,"live": false,"blocked": false},"flow-node-inventory:name": "s1-eth1","flow-node-inventory:maximum-speed": 0,"flow-node-inventory:configuration": "","flow-node-inventory:supported": "","flow-node-inventory:peer-features": "","flow-node-inventory:port-number": "1","flow-node-inventory:advertised-features": "","flow-node-inventory:current-feature": "ten-gb-fd copper","flow-node-inventory:hardware-address": "12:ea:18:e9:ee:28","flow-node-inventory:current-speed": 10000000,"opendaylight-port-statistics:flow-capable-node-connector-statistics": {"transmit-drops": 0,"receive-frame-error": 0,"receive-drops": 0,"receive-crc-error": 0,"bytes": {"transmitted": 10725,"received": 560},"duration": {"nanosecond": 462000000,"second": 560},"receive-errors": 0,"transmit-errors": 0,"receive-over-run-error": 0,"collision-count": 0,"packets": {"transmitted": 129,"received": 8}},"address-tracker:addresses": [{"id": 0,"first-seen": 1494576603869,"mac": "00:00:00:00:00:01","last-seen": 1494576603869,"ip": "10.0.0.1"}]}]
}

主机检测

往ODL控制器发送下面的Rest请求，可以查看到全网络链路的所有主机（包括交换机与普通主机）以及之间的链接情况。

http://10.0.3.100:8181/restconf/operational/network-topology:network-topology/topology/flow:1/

得到的响应内容如下：
