On-demand packet loss and delay measurement

Junos OS introduces an on-demand tool to monitor and measure packet loss, packet delay, or both for associated bidirectional MPLS ultimate hop popping (UHP) point-to-point label-switched paths (LSPs), using the monitor mpls loss rsvp, monitor mpls delay rsvp, and monitor mpls loss-delay rsvp commands, respectively. These commands provide an on-demand summary of performance metrics for direct mode packet loss, two-way packet delay, and related metrics, such as inter-packet delay variation and channel throughput measurement. This functionality provides real-time visibility into network performance, thereby facilitating network performance planning, troubleshooting, and evaluation.
