Lab 7: Read samples from file and send them to node

Easy way (non real-time)

Send and receive samples from files to simulator.

villas pipe lab3.conf udp_node1 < file_send.dat > file_recv.dat

Note: In this lab all samples of file.dat will be sent immediately to udp_node1. Usually, this is not the desired behavior. We will show later how to stream the samples in real-time to a destination node.

Better way (real-time)

node/etc/labs/lab7.conf

nodes = {
    file_node1 = {
        type = "file"

        uri = "file_send.dat"

        in = {

        }
    }
}

In order to stream the samples in real-time from a file, we will use the file node-type with the following configuration file (lab7.conf):

Stream samples in real-time from file.

villas pipe lab7.conf file_node1 | villas pipe lab3.conf udp_node1 > file_recv.dat
