Anda telah memutuskan bahwa Anda ingin bereksperimen dengan multicast lintas jaringan menggunakan OpenWeave. Panduan cara ini menggambarkan penggunaan alat simulasi jaringan Happy untuk menyiapkan topologi virtual yang menunjukkan penggunaan lapisan Inet OpenWeave di dua jaringan berbeda dengan proxy multicast.
Unduh dan buat mcproxy
IPv6 multicast daemon proxy, mcproxy
, berfungsi untuk proxy / maju / rute IPv6 lalu lintas multicast di dua link jaringan menguraikan IPv6.
Meskipun tidak terlalu penting di mana Anda mengkloning dan membangun mcproxy
daemon dieksekusi, harap perhatikan lokasi di mana Anda membuat itu sebagai jalan relatif atau absolut untuk itu perlu pada Langkah 6 di bawah ini.
git clone https://github.com/mcproxy/mcproxy.git mcproxy
sudo apt-get install qt5-qmake qt5-default
cd mcproxy/mcproxy
qmake
make
Unduh, bangun, dan instal dengan senang
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
Unduh dan buat openweave-core
git clone https://github.com/openweave/openweave-core.git openweave-core
cd openweave-core
./configure
make
Tetapkan topologi Happy
Hal ini menciptakan topologi sangat mirip dengan Selamat Codelab .
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
Buat konfigurasi mcproxy untuk topologi Happy
Ini menciptakan konfigurasi proxy multicast IPv6 antara antarmuka jaringan "Thread" yang disimulasikan pada "wpan0" dan antarmuka jaringan "WiFi" yang disimulasikan pada "wlan0" di topologi Happy yang kami buat di atas pada Langkah 4.
Meskipun tidak terlalu penting di mana Anda membuat mcproxy.conf
file, silahkan perhatikan lokasi di mana Anda membuat itu sebagai jalan relatif atau absolut untuk itu perlu pada Langkah 6.
cat > mcproxy.conf << EOF
protocol MLDv2;
pinstance myProxy: wpan0 ==> wlan0;
EOF
Jalankan demonstrasi
Ini menjalankan IPv6 proksi multicast, mcproxy
, pada "BorderRouter" simpul dan kemudian meluncurkan Inet lapisan pengirim tes multicast fungsional dan penerima pada simulasi "Thread" dan "WiFi" node, masing-masing.
Jika mau, Anda dapat mengubah posisi node pengirim dan penerima dan contohnya juga akan berfungsi dengan baik.
Setiap set perintah berikut harus dijalankan dari shell paralel dan independen.
