[c-nsp] Detection of Link Performance degradation

[Dracul]

Hi Steve,

I was looking more into this scenario:

ex. actual line is 2MB, no usage, now how can one tell if the actual 2MB
link is degrading its speed? Like is there a real time detection
that download speed has actually degraded from the 2MB config?

hope this is clearer. thanks!

regards,
chris
