STC testing on singleONOSinstance

ONOS instance setup

onos setup

# This scrip is used to test ODTN on single ONOS instance in branch 2.0
# Before this script:
#   1. Make sure the default Python version is 2.x
#   2. Run ONOS locally (bazel run onos-local -- clean)
#   3. Start sshd service, and make sure "ssh $USER@localhost" operation doesn't need passwd
#   4. Emulator configuration could be found under directory $HOME/emulator

# env configuration based on the default ONOS environment
# single ONOS instance runs on local machine directly

# The emulators run as docker containers.
docker-compose up -d

About the emulator

The directory ${EMULATOR_ROOT} contains:

File "docker-compose.yaml"
Directory "emulator-oc-cassini"
File "net-summary.json" - This file contains one-line json content to describe the network topology briefly ("{"device_num":"2","port_num":"64","link_num":"12"}"), aiming to help information check for topology discovery.

The topology view shows:
