VoIP Burst Density
A burst is a period of time characterized by high rates of packet loss. Burst density is the rate of VoIP data packets lost during these burst periods, expressed as a percentage of all VoIP packets.
Higher burst densities affect call quality, especially when coupled with long burst duration times. Possible reason for packet loss include network congestion, media failure, and link failure. Long, high-density burst periods often point to media failure such as bad cabling or poor wireless signal quality. Lower density, intermittent bursts suggest more transient network conditions (for example, congestion) as the culprit.
