Middleware for Odin Applications: Send statistics from the Agent to the Controller

[josemariasaldana]

The possibility of sending parameters from the AP to the controller can be done in two ways:

• Statistics: The Controller requests statistics from an AP, using the call getRxStatsFromAgent, defined in odin-master/src/main/java/net/floodlightcontroller/odin/master/OdinMaster.java, and in the Agent in https://github.com/Wi5/odin-wi5-agent/blob/master/src/odinagent.cc
• Subscriptions: Currently subscriptions only consider the possibility of sending the power level of a packet. However, perhaps the Agent could continuously calculate the average power, throughput, etc, and send periodic packets with statistics.

A subscription should be first defined in the Controller, specifying the kind of statistics required, the periodicity, etc.

We are currently working on this, in the statistics branches:

https://github.com/Wi5/odin-wi5-agent/tree/statistics

https://github.com/Wi5/odin-wi5-controller/tree/statistics We need to modify these files of the controller:

src/main/java/net/floodlightcontroller/odin/master/OdinMaster.java 
src/main/java/net/floodlightcontroller/odin/master/OdinAgent.java
src/main/java/net/floodlightcontroller/odin/master/IOdinApplicationInterface.java 
src/main/java/net/floodlightcontroller/odin/master/StubOdinAgent.java 
src/main/java/net/floodlightcontroller/odin/master/IOdinAgent.java 
src/main/java/net/floodlightcontroller/odin/master/OdinApplication.java
src/main/java/net/floodlightcontroller/odin/master/IOdinMasterToApplicationInterface.java

It works. We have merged the changes to the Development branch:

Agent: https://github.com/Wi5/odin-wi5-agent/commit/5f4208f3c1b8861628101463874b6762360a59f1

Controller: https://github.com/Wi5/odin-wi5-controller/commit/8151a61d227b2782f93210460d456fb176c2cf93
