Update profile.py

parent c769f81b
"""This is a trivial example of a gitrepo-based profile; The profile source code and other software, documentation, etc. are stored in in a publicly accessible GIT repository (say, github.com). When you instantiate this profile, the repository is cloned to all of the nodes in your experiment, to `/local/repository`.
This particular profile is a simple example of using a single raw PC. It can be instantiated on any cluster; the node will boot the default operating system, which is typically a recent version of Ubuntu.
#!/usr/bin/env python
"""
NOTE: This profile tracks more recent versions of OAI (develop branch),
and is likely to change more frequently.
Use this profile to instantiate an experiment using Open Air Interface
to realize an end-to-end SDR-based mobile network. This profile includes
the following resources:
* Off-the-shelf Nexus 5 UE running Android 4.4.4 KitKat ('rue1')
* SDR eNodeB (Intel NUC + USRP B210) running OAI on Ubuntu 16 ('enb1')
* All-in-one EPC node (HSS, MME, SPGW) running OAI on Ubuntu 16 ('epc')
* A node providing out-of-band ADB access to the UE ('adb-tgt')
PhantomNet startup scripts automatically configure OAI for the
specific allocated resources.
Instructions:
Wait for the profile instance to start, then click on the node in the topology and choose the `shell` menu item.
Be sure to setup your SSH keys as outlined in the manual; it's better
to log in via a real SSH client to the nodes in your experiment.
The Open Air Interface source is located under /opt/oai on the enb1
and epc nodes. It is mounted as a clone of a remote blockstore
(dataset) maintained by PhantomNet. Feel free to change anything in
here, but be aware that your changes will not persist when your
experiment terminates.
To access the UE via ADB, first log in to the 'adb-tgt' node, then run
'pnadb -a' to connect to the UE. Use ADB commands as per normal
afterward. If/when you reboot the UE, be aware that you will need to
again run 'pnadb -a' to reestablish the ADB connection; wait a minute
or so for the UE to become available again before doing this.
The OAI mobile networking functions should automatically start up when
your experiment starts up. You can pull up and monitor the OAI
processes on the 'epc' and 'enb' nodes. Execute 'sudo screen -ls'
to see what sessions are available.
