6 Tips Before Putting Voice on MPLS

摘要

Don't let the name fool you. The "real-time voice" class of service on your MPLS network isn't necessarily the best way to transport your IP voice traffic. Consider sending it over the highest data class of service instead. It's a neat workaround that could save you from some engineering and sizing exercises, says David Lee, senior consultant at TechCaliber Consulting, in Washington, D.C. The voice class of service will start dropping packets once the traffic exceeds the allotted bandwidth to prevent jitter (when packets arrive at different intervals). But the highest data class of service is "burstable," so any traffic that exceeds the bandwidth allotted to that class won't get dropped, Lee explains.
