MicroView Control Plane

An implementation SmartNIC-to-host communication via RDMA for microservices metrics.

The description of the project can be found in our published research paper:

Run instructions

Start agent on localhost running:

make
./agent

This will start microview agent at port 12345. Then run the following replacing SERVER_ADDR with the MicroView agent address. If MicroView runs on node use host.docker.internal:

docker run --rm --name pod --ipc=host --add-host=host.docker.internal:host-gateway acornacchia/ipc "./pod" "SERVER_ADDR"

The container should:

1. Open a TCP connection to the agent and ask for a shared memory segment
2. Start writing metrics to such a memory segment

On the other hand, MicroView agent:

1. allocates shared memory region and closes TCP connection
2. sends RDMA R_key to the microview agent counter part which sits on the SmartNIC
