Hi,
so I decided to go with a statsmanager component that measures delay and
packet loss for every link found by the discovery component.
To measure delay, I will send ICMP echo requests and measure the RTT for
the links to the switches and then send a packet from the controller to
switchA
Hi Kyriakos,
yes I know of the propagation delays of the control channels. I thought
of measuring these by simple ICMP Echo Requests and extracting the RTT
from that. Assuming that we have symmetric channels, I can get an
estimate of these delays and use them in the delay calculation.
The
Hi,
I am currently working on a component that needs a lot of statistical
information about the current network state.
In fact, I need the packet lLoss rate and the delay of single links
between OpenFlow-switches.
The PLR can be computed quite easily from the statistics that the switch
gives
