> Key: QPID-1050
> URL: https://issues.apache.org/jira/browse/QPID-1050
> Project: Qpid
> Issue Type: New Feature
> Components: C++ Broker
> Affects Versions: M3
> Reporter: Ted Ross
> Fix For: M3
>
> Attachments: qpid-patch45.diff

>
> The attached patch contains the following changes:
> 1) Durability for federation links (broker-to-broker connections)
> 2) Improved handling of federation links:
> a) Links can be created even if the remote broker is not reachable
> b) If links are lost, re-establishment will occur using an exponential
> back-off algorithm
> 3) Durability of exchanges is now viewable through management
> 4) ManagementAgent API has been moved to an interface class to reduce
> coupling between the broker and manageable plug-ins.
> 5) General configuration storage capability has been added to the
> store/recover interface. This is used for federation links.
> 6) Management object-ids for durable objects are now themselves durable.
> Special note:
> To support the new federation features, it was necessary to create a new
> class called ProtocolAccess. This class is used to consolidate linkage
> between previously unlinked objects in the architecture. For example,
> federation link objects need to know when TCP connections are lost and they
> need access to Connection objects so that bridge configuration can be managed.
> Since "management plane" logic needs access to a wide variety of operational
> objects, ProtocolAccess was introduced. ProtocolAccess isolates in one place
> the "controversial" architectural linkages needed for federation. If,
> through team review, it is decided in the future to use a different
> architecture, ProtocolAccess can easily be removed and replaced.
> Features still missing:
> In the interest of getting these changes submitted, I have left out several
> necessary features. These can be added after a few more hours worth of work.
> 1) Durability for federation "Bridge" configuration
> 2) Link management in the qpid-route utility (i.e. the ability to view link
> status and troubleshoot connectivity issues)
> 3) Use of supplied credentials in inter-broker link establishment
