[pox-dev] manage events in Pox

[Hanieh Rajabi]

Hi folk,
I am very newbie to Pox and
I need to develope a framework that implements the monitoring of SDN
networks.
To do this job I've integrated a monitoring application in my framework
which send to Pox controller the alert of any suspected flow on the fly and
suppose the controller can manage this alerts in terms of installing
appropriate rules in the openflow switch.

To handle this tasks, I thought to define different events in Pox such as
AlertDDoS event and AlertDNSPoisioning event etc,...

On the other hand, I need to have ConnectionUp event that trigger when the
switch connect to openflow and start sending the alerts on suspected flow
to the controller.
Therefore in _handle_ConnectionUp function I run a tcp server that receives
the xml msg and parse them to find the alert on the flow
if there is any alert I would like to raise AlertDDoS event in order to
compute and install the new rule.
My question is that when pox is in _handle_ConnectionUp function is it
possible to raise another event and force pox to execute _handle_AlertDDoS
function??
Is defining the events to manage this situation is a good idea?

Thank you in advance.
Hanieh
