Valinor-c timestamp collection component for Valinor framework

This DPDK program collects timestamp records generated by Valinor-N in-network measurement framework and stores timestamp records in Redis.

More information can be found at in our NSDI paper.

Also checkout Valinor super repository.

Requirements for Valinor measurement framework

• dpdk-stable-20.11.4
• Redis server running on localhost

Installation and Running

• Install and test DPDK 20.11.4
• Install Redis server and verify connection to redis-server via redis-cli
• Setup huge pages. 1GB huge pages are recommended for better performance of Valinor. For our experiments we have 40x 1GB pages allocated on runtime.
• run git submodule init and git submodule update to checkout hiredis sources. Then run make and make install under ext/hiredis to build and install hiredis.
• The command to run the valinor-c dataplane is sudo ./build/valinor -- -p 0x1 -c server.json -k 0. the -p flag is use by DPDK to determine the network interface used by Valinor. The -k flag is the key used by redis-server to store timestamp records under. The configurations in server.json file can be modified as needed.
