The current structure of the High Level Architecture (HLA) puts a tremendous burden on network load and CPU utilization for large distributed simulations due to its limited controls for publishing and subscribing object updates and interactions. Several solutions to this problem have been proposed, but all require cooperation between federate developers and FOM extensions for both the publishing and subscribing Federates. This paper explores an alternative that has the potential to dramatically reduce communications load by allowing subscribing federates to extend and control the publish/subscribe mechanisms that are local to the publishing federate's process without requiring changes to the publishing federate or the Federation Object Model (FOM).
