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

Specifies the average bit rate of the sender's data stream.

Within a transmission burst, the arrival rate could be as fast as rsvpResvFwdTSpecPeakRate. However, averaged across two or more burst intervals, the rate should not exceed rsvpResvFwdTSpecRate.



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

Indicates the peak bit rate of the sender's data stream. This is the maximum traffic arrival expected at any time, except for the effects of network jitter.

If the value is zero or noSuchValue, peak bit rate is not specified in the TSpec.


Burst Size (rsvpResvFwdTSpecBurst )

Indicates the size of the largest burst expected from a sender at one time.

If the burst size is less than the sender's advertised burst size, the receiver is asking the network to provide flow pacing beyond what would be provided under normal circumstances. Such pacing is at the network's option.

 



Minimum Message Size (rsvpResvFwdTSpecMinTU)

Indicates the minimum message size of a flow.

 



Maximun Message Size (rsvpResvFwdTSpecMaxTU)

Indicates the maximum message size for a flow.

The admission algorithm rejects TSpecs whose maximum transmission unit, plus the interface headers, exceeds the interface MTU.


Clearing Rate (rsvpResvFwdRSpecRate)(units: bytes per second)

Specifies the requested clearing rate when the requested service is guaranteed.

If the value is zero or noSuchValue, the requested service is not guaranteed.

 


Delay Slack (rsvpResvFwdRSpecSlack)(units: microseconds)

Specifies the delay slack when the requested service is guaranteed.

If the value is zero or noSuchValue, the requested service is not guaranteed.



Refresh Message Interval (rsvpResvFwdInterval)

Specifies the interval between refresh messages advertised to the Previous Hop.


rsvpResvFwdScope (rsvpResvFwdScope)

Indicates the contents of the scope object including the object header.

If the value is zero or noSuchValue, the object is not present.


Shared Reservation (rsvpResvFwdShared)

Indicates the status of the reservation requested.

Value

Description

True

A reservation shared among the senders is requested.

False

A reservation specific to the sender is requested.



Explicit Senders (rsvpResvFwdExplicit)

Specifies how a sender is selected.

Value

Description

True

Individual senders are listed using filter specifications.

False

All senders are implicitly selected.

The scope object retains a list of senders that need to receive the reservation request for the purpose of routing the RESV message.


RSVP hop (rsvpResvFwdRSVPHop)

Indicates the type of next RSVP hop.

Value

Description

True

Next IP hop is an RSVP hop.

False

Next IP hop may not be an RSVP hop.



Last Change (rsvpResvFwdLastChange)

Indicates the time of last change in a request.

The value indicates the first time it was sent or the time of the most recent parameter change.


 Policy (rsvpResvFwdPolicy)

Indicates the contents of the policy object including the object header.
