> Reimplement mobile-sync as a core module
> ----------------------------------------
>
> Key: DISPATCH-1532
> URL: https://issues.apache.org/jira/browse/DISPATCH-1532
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Routing Engine
> Reporter: Ted Ross
> Assignee: Ted Ross
> Priority: Major
> Fix For: 1.11.0
>
>
> The code in Qpid Dispatch Router currently does mobile address
> synchronization between routers in the Python router module. This has a
> couple of drawbacks in cases where there are large numbers of addresses:
> * The address strings are stored twice: once in the main address lookup
> hash table and again in the Python mobile address module.
> * Address lookup on the Python side is inefficient and has been a bottleneck
> (improved recently by a patch from Gordon Sim).
> * Python processing is single threaded. A large mobile address update can
> cause delays in processing management requests and link-state topology
> maintenance.
> The python router module was intended to be an on-the-side control-plane
> moduel that was not in the critical path for any performance-related
> activities. With large numbers of addresses in a network, synchronizing
> address locations becomes performance-related.
> To address these issues, mobile address synchronization can be moved into a
> core module where it can use and share the same address table that is used by
> the router core for make high speed routing decisions. In the process, it
> will leave the python modules alone to process management requests and
> topology maintenance uninterrupted.
