# This is an example for a minimal loopback configuration. # # All messages will be sent back to the origin using UDP packets. # # You can use this configuration in conjunction with the 'send', 'receive' and 'random' # utilities as shown below (run all three steps in parallel). # # 0. Overview: # # ./signal --PIPE--> ./pipe --UDP--> ./node --UDP--> ./pipe # # 1. Start server: # # $ ./node etc/loopback.conf # # 2. Send random data to server: # # $ ./signal random -r 10 -v 4 | ./pipe etc/loopback.conf node1 # # 3. Receive data from server: # # $ ./pipe etc/loopback.conf node2 # # Author: Steffen Vogel <post@steffenvogel.de> # SPDX-FileCopyrightText: 2014-2023 Institute for Automation of Complex Power Systems, RWTH Aachen University # SPDX-License-Identifier: Apache-2.0 logging = { level = "debug" } nodes = { node1 = { type = "socket", format = { type = "gtnet" fake = true } in = { address = "134.130.169.31:12002" # Local ip:port, use '*' for random port } out = { address = "134.130.169.98:12001" } netem = { enabled = false delay = 1000000 # In micro seconds! jitter = 300000 distribution = "normal" } }, node2 = { type = "socket", format = { type = "gtnet" fake = true } in = { address = "134.130.169.31:12004", # Local ip:port, use '*' for random port } out = { address = "134.130.169.99:12003", } } } paths = ( { in = "node1" # Name of the node we listen to (see above) out = "node1" # And we loop back to the origin hooks = ( { type = "print" } ) }, { in = "node2", out = "node2", hooks = ( { type = "print" } ) } )
