Network Physics VoIP Quality Monitors
December 30, 2006Network Physics VoIP Quality Monitors
VoIP sys admins will have another potential tool in their arsenal with new VoIP quality monitors
from Network Physics. The offering, called NetSensory Solution Insight for VoIP, works as anextension set for Network Physics’ appliances. These extensions measureover 60 metrics related to VoIP call quality.
AsI’ve pointed out before, there are many factors that affect VoIP callservice, but
I wouldn’t have thought there were even 60 IP metrics, letalone that many that affect call quality. Things I haven’t touched onbefore, which Network Physic’s solution does, includes using theappropriate CODEC(Coder-decoder) algorithm. Essentially, there are different algorithmsto compress and decompress digital audio data, and some perform on thefly better than others, depending on issues related to both network andcomputing resources.
