Hi,
I've been developping a NOX app which needs to get the traffic load of
all the links of the openflow switches. I've been trying to do so with
the "networkstate/linkload.hh" functions.
Everytime I call the get_link_load_ratio() function with all the propper
parameters it returns -1 (as if it wasn't possible to get the link load).
I can see in the function definition that get_link_load_ratio() returns
-1 when the link speed or the measurement interval are equal to 0. The
links whose load I try to measure are connected at 100Mbps so I don't
understand the cause of this error.
Is there any reason for this function to return -1 in this conditions?
Is there another way to get the load of a link?
Thank you.
