Tailorable Location Policies for Distributed Object Systems

Distributed object applications rely heavily on distributed systems and objects. Solutions using CORBA with its location transparency are inefficient and do not scale for high-throughput networked applications. Our work addresses these inefficiencies by creating a mechanism enabling applications to influence the system’s object location policies on an object-by-object basis.We also provide an analytic comparison of distributed object systems that do and do not support location transparency and caching policies. The analysis shows that by using tailorable policies it is possible to achieve significantly increased performance through the reduction of the message traffic so that it is only a fraction of a percent of the message traffic required to implement a standard CORBA policy.
