jDiameter doesn't differentiate between the various Disconnect-Cause AVPs when handling a Disconnect-Peer-Request

[stevedwyer-nasstar]

According to RFC6733, sections 5.4.1. Disconnect-Peer-Request and specifically 5.4.3. Disconnect-Cause AVP, which is sent with the Disconnect-Peer-Request:

5.4.3. Disconnect-Cause AVP

The Disconnect-Cause AVP (AVP Code 273) is of type Enumerated. A
Diameter node MUST include this AVP in the Disconnect-Peer-Request
message to inform the peer of the reason for its intention to shut
down the transport connection. The following values are supported:

  REBOOTING                         0
     A scheduled reboot is imminent.  A receiver of a DPR with
     above result code MAY attempt reconnection.

  BUSY                              1
     The peer's internal resources are constrained, and it has
     determined that the transport connection needs to be closed.
     A receiver of a DPR with above result code SHOULD NOT attempt
     reconnection.

  DO_NOT_WANT_TO_TALK_TO_YOU        2
     The peer has determined that it does not see a need for the
     transport connection to exist, since it does not expect any
     messages to be exchanged in the near future.  A receiver of a
     DPR with above result code SHOULD NOT attempt reconnection.

However, when Disconnect-Cause AVP 0 REBOOTING is sent from a server, the jDiameter client doesn't attempt to reconnect. This means that if a peer is restarted for maintenance, the jDiameter stack will mark it as DOWN and will never attempt to reconnect to it.

Awaiting merge of #156 before I raise a pull request for commit f5dfa15 - due to the business constraints of delivering functionality, this work has been done in succession in order to deliver a jDiameter stack which meets our project's requirements.
