#########################################
# This script start  ENB  
# Depending on configuration files, it can be instanciated a virtual switch

# MME+SP-GW executable have to be launched on the same host by your own (start_epc.bash) before this script is invoked.
# UE executable have to be launched on another host by your own (start_ue.bash) after this script is invoked.
