The number of MPLS octets that have been forwarded over this
RSVP Session. The number reported is not realtime, may subject to
several minutes delay. The delay is controllable by mpls statistics
gathering interval, which by default is once every 5 minutes.
If mpls statistics gathering is not enabled, this number will not
increment. Discontinuities in the value of this counter can
occur at re-initialization of the management system, and at other
times as indicated by the value of jnxRsvpSessionDiscontinuityTime.
