OpenWeave + 快樂跨網絡組播 Inet 層 HOWTO

您已決定要使用 OpenWeave 試驗跨網絡多播。本操作指南說明瞭如何使用 Happy 網絡模擬工具來設置虛擬拓撲，該拓撲演示如何使用 OpenWeave 的 Inet 層跨兩個不同的網絡和多播代理。

下載並構建 mcproxy

IPv6組播代理守護進程， mcproxy ，用於代理/轉發/路由IPv6組播流量橫跨兩個不相交的IPv6網絡鏈接。

雖然它在那裡你克隆和構建並不是特別重要mcproxy守護程序的可執行文件，請大家在其中創建它作為一個相對或絕對路徑，它是在下面的步驟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

下載、構建和安裝快樂

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

下載並構建 openweave-core

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

建立Happy拓撲

這將創建非常相似的拓撲快樂程式碼實驗室。

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-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

為 Happy 拓撲創建 mcproxy 配置

這將在我們在上面步驟 4 中創建的 Happy 拓撲中的“wpan0”上的模擬“Thread”網絡接口和“wlan0”上的模擬“WiFi”網絡接口之間創建 IPv6 多播代理配置。

雖然在其中創建的不是特別重要mcproxy.conf文件，請大家在其中創建它給它的相對或絕對路徑是在第6步必要位置的音符。

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

運行演示

這將運行的IPv6多播代理， mcproxy中，“BorderRouter”節點上，然後啟動在INET層組播功能測試發送者和接收者在模擬“線程”和“WiFi”的節點，分別。

如果您願意，您可以調換發送方和接收方節點，並且該示例也同樣有效。

以下每組命令都應該從並行、獨立的 shell 中運行。

邊界路由器

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