mptcp_with_machine_learning
How to run (in root directory of ns3):
1.configure compile condition
CXXFLAGS=" -std=c++11" ./waf --enable-examples configure
2.compile
./waf
3.run script
bash RL-MPTCP_debug_NS3.sh
P.S.
bash RL-MPTCP_run.sh
runs multiple python program for statistic and analyzing. But lots of path for file storage in them is hard coded and only fits for my machine, my bad :(
Env: gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) ubuntu 14.04: kernel version 4.2.0-27-generic Python 2.7.12 | Anaconda 4.2.0 (64-bit) Tensorflow 0.12.0
Details:
- The MpTCP applications (on-off/file transfer) in scratch/run/mp-onoff-application.cc only use multiple IP addresses of server.
- Example: let a server A own IP: 192.168.0.1 and 192.168.0.2, a client B own IP: 192.168.0.3 and 192.168.0.4. Then, the whole process is like this:
- Server A establishes the master subflow of MpTCP to B with socket (192.168.0.1, xxxx, 192.168.0.3, yyyy)
- After master subflow is fully established (Sever A gets first DSS from Client B), server A starts to check a new subflow is available or not. If available, A sends MP_JOIN through address 192.168.0.2:zzzz back to B's 192.168.0.3:yyyy to request a new subflow.
- Then, B does a simple one way hand shake with A's 192.168.0.2:zzzz through address 192.168.0.3:yyyy to establish socket (192.168.0.2, zzzz, 192.168.0.3, yyyy). Security is promised by token/nonce check.
For detailed logic: MpOnOffApplication::ConnectionFullyEstablished()
And this specific simulation can be regarded as IPhone use multiple subflows to connect to Siri's server.
