# RSVP TSpec Information

The table displays following information:

> Average Bit Rate (rsvpSenderTSpecRate)

> Peak Bit Rate (rsvpSenderTSpecPeakRate)

> Burst Size (rsvpSenderTSpecBurst)

> Minimum Message Size (rsvpSenderTSpecMinTU)

> Maximum Message Size (rsvpSenderTSpecMaxTU)

> Refresh Message Interval (rsvpSenderInterval)

> rsvpSenderRSVPHop (rsvpSenderRSVPHop)

> Last Change (rsvpSenderLastChange)

Average Bit Rate (rsvpSenderTSpecRate) (units: bits per second)

Average bit rate of sender's data stream.
Within a transmission burst, the arrival rate could be as fast as rsvpSenderTSpecPeakRate (if supported by the service model); however, averaged across two or more burst intervals, the rate should not exceed rsvpSenderTSpecRate.

Peak Bit Rate (rsvpSenderTSpecPeakRate) (units: bits per second)

Peak bit rate of sender's data stream.
Traffic arrival is not expected to exceed this rate at any time, apart from the effects of jitter in the network. If not specified in TSpec, Peak Bit Rate returns zero or noSuchValue.

Burst Size (rsvpSenderTSpecBurst)

Size of the largest burst, in bits, expected from the sender at one time.

Minimum Message Size (rsvpSenderTSpecMinTU)

Minimum message size size for the flow.
Messages smaller than rsvpSenderTSpecMinTU are considered minimum size messages.

Maximum Message Size (rsvpSenderTSpecMaxTU)

Maximum message size for a flow.

Admission algorithm rejects Tspecs with interface MTU greater than the sum of maximum transmission unit (MTU) and the interface headers.

Refresh message Interval (rsvpSenderInterval)

Interval between refresh messages as advertised by the previous hop.

rsvpSenderRSVPHop (rsvpSenderRSVPHop)

Indicates whether a hop is an RSVP hop.

Possible values are True and False.

Value | Description
True | Previous IP hop is an RSVP hop.
False | previous IP hop is not an RSVP hop.

Last Change (rsvpSenderLastChange)

Time of the last change in PATH message.
Last change also means the first time it was received or the time of the most recent parameter change.
