     727Things to test. There are several things that can be tweaked, each with some type of consequence:
     728 1. ''number of switches. '' Control packets and channels are tracked in terms of switches and controllers. More switches mean more state to track and save, each switch that detects a given event will generate its own set of event messages.
     729 1. ''number of hosts. '' Unique host traffic is the prototypical trigger for message events. More hosts intuitively generate more events.
     730 1. ''number of hops. '' A longer route to a particular service will add more network transport delays (propagation, queueing, kernel buffer etc). This makes for a potentially infrastructure-sensitive control plane. We use short, high-throughput links for our experiments.
     731 1. ''number of services. '' More services (handlers) touching a certain event naturally incurs more processing overhead.   
     732   
     733Infrastructure. Hardware depends on what we get access to, but it is generally a quad or hex-core PC. All tests ore done using Ubuntu 12.04, since it is the de-facto platform for all of the software.
