DRN and TID Label Issues - Issue #8

Lincoln,

RFC 3868 says:

4.3.4.5.  Notify Procedures

   A Notify message reflecting a change in the AS state MUST be sent to
   all ASPs in the AS, except those in the ASP-DOWN state, with
   appropriate Status Information and any ASP Identifier of the failed
   ASP.  At the ASP, Layer Management is informed with an M-NOTIFY
   indication primitive.  The Notify message must be sent whether the AS
   state change was a result of an ASP failure or reception of an ASP
   State management (ASPSM) / ASP Traffic Management (ASPTM) message.
   In the second case, the Notify message MUST be sent after any ASP
   State or Traffic Management related acknowledgement messages  (e.g.,
   ASP Up Ack, ASP Down Ack, ASP Active Ack, or ASP Inactive Ack).


Application of DRN/TID label is inconsistent with the adopted
notification procedures.  The SG always notifies the ASPs with
a Notify message when traffic is pending or in danger of being
discarded.

DRN/TID has no notification procedure when a ASP Inactive is
received for a necessary label range, nor when an unsolicited
ASP Inactive Ack is sent.

(LOADSEL has a notification procedure BTW.)
