Abstract:

The paper discusses the impact of multiple interceptor lading on the request/reply round-up time, and presents an interceptor runtime model which features branching and concurrence to resolve the contradiction of long time in providing interceptor-related services and request respondence. The model adopts a tree-like organizational form, and has been implemented in the Starbus 5.0 CORBA middleware.

Key words: portable interceptor, PI, ORB, interception point
