Abstract:
CORBA as a standardized object-based middleware for distributed computing
still lacks sufficient support for mobility and replication, although there
are several proposals to integrate these mechanisms. AspectIX is a more flexible
and more open architecture than CORBA, but AspectIX is still fully CORBA compliant.
Unlike CORBA with its static client-server relationship, AspectIX uses the concept
of distributed objects. Each distributed object is represented by at least one
local part, called fragment, that communicates with other fragments to synthesize
the desired behaviour. The fragment implementation that is actually used depends on
nonfunctional aspects which are specified on the distributed object via a typed interface.
Based on this model AspectIX provides a single mechanism that is especially suited to
realize both: mobility and replication.
