OpenWeave + 快乐跨网络组播 Inet 层 HOWTO

您已决定要使用 OpenWeave 试验跨网络多播。本操作指南说明了使用 Happy 网络模拟工具来设置虚拟拓扑，该拓扑演示了如何使用 OpenWeave 的 Inet 层跨两个不同的网络和多播代理。

下载并构建 mcproxy

IPv6组播代理守护进程， mcproxy ，用于代理/转发/路由IPv6组播流量横跨两个不相交的IPv6网络链接。

虽然它在那里你克隆和构建并不是特别重要mcproxy守护程序的可执行文件，请大家在其中创建它作为一个相对或绝对路径，它是在下面的步骤6必要位置的音符。

git clone https://github.com/mcproxy/mcproxy.git mcproxy
sudo apt-get install qt5-qmake qt5-default
cd mcproxy/mcproxy
qmake
make

下载、构建和安装快乐

git clone https://github.com/openweave/happy.git happy
sudo apt-get install bridge-utils python-lockfile python-psutil python-setuptools
cd happy
sudo make install

下载并构建 openweave-core

git clone https://github.com/openweave/openweave-core.git openweave-core
cd openweave-core
./configure
make

建立Happy拓扑

这将创建非常相似的拓扑快乐程式码实验室。

happy-network-add ThreadNetwork thread
happy-network-address ThreadNetwork fd00:0000:0000:0006::
happy-network-add WiFiNetwork wifi
happy-network-address WiFiNetwork fd00:0000:0000:0001::
happy-network-address WiFiNetwork 192.168.1.0
happy-node-add ThreadNode
happy-node-add WiFiNode
happy-node-add BorderRouter
happy-node-join ThreadNode ThreadNetwork
happy-node-join WiFiNode WiFiNetwork
happy-node-join BorderRouter ThreadNetwork
happy-node-join BorderRouter WiFiNetwork
happy-network-route --prefix fd00:0000:0000:0006:: ThreadNetwork BorderRouter
happy-network-route --prefix fd00:0000:0000:0001:: WiFiNetwork BorderRouter
happy-network-route --prefix 192.168.1.0 WiFiNetwork BorderRouter

为 Happy 拓扑创建 mcproxy 配置

这将在我们在上面步骤 4 中创建的 Happy 拓扑中的“wpan0”上的模拟“Thread”网络接口和“wlan0”上的模拟“WiFi”网络接口之间创建一个 IPv6 多播代理配置。

虽然在其中创建的不是特别重要mcproxy.conf文件，请大家在其中创建它给它的相对或绝对路径是在第6步必要位置的音符。

cat > mcproxy.conf << EOF
protocol MLDv2;
pinstance myProxy: wpan0 ==> wlan0;
EOF

运行演示

这将运行的IPv6多播代理， mcproxy中，“BorderRouter”节点上，然后启动在INET层组播功能测试发送者和接收者在模拟“线程”和“WiFi”的节点，分别。

如果您愿意，您可以调换发送方和接收方节点，并且该示例也同样有效。

下面的每组命令都应该从并行、独立的 shell 中运行。

边界路由器

happy-shell BorderRouter
<path-to-mcproxy-from-step1>/mcproxy -f <path-to-mcproxy-config-from-step5>/mcproxy.conf
