The tested results is put in p4sim-artifact-icns3 .

Examples

The example consists of two parts:

• A simulation script in ns-3, which is used to build the simulation environment.

• A set of files in the p4src directory, including the network topology description (topo.txt), the P4 program(*.p4, *.p4i, *.json), and the corresponding flow table configuration (flowtable_x.txt).
