Detailed Description

The strategy to handle observers for the Event Channel subscriptions and publication.

The Event Channel supports Observers for the set of subscriptions and publications. This is used to implement federations of event channels, either through UDP (multicast and unicast) and/or regular CORBA calls. This behavior of the EC is strategized to avoid overhead when no gateways are needed.
