Title:
METHOD FOR ANALYSING TRANSMITTED PROTOCOL DATA UNITS
Document Type and Number:
WIPO Patent Application WO2001079991
Kind Code:
A3
Abstract:
The invention relates to a method for analysing transmitted protocol data units, especially of the General Inter ORB protocol, comprising three phases in the General Inter ORB decoder in relation to a single object -an initialisation phase, a learning phase and a decoding phase- so that the messages contained can be represented as completely as possible. In the initialisation phase, lists of all possible interface definitions are established. These lists are stored specifically for a particular host, a particular agent or an agent-specific destination address. In the learning phase, exclusion criteria are used to reduce the number of possibilities, although the evaluated message cannot yet be decoded definitively. There are still more than one interface definitions that may form the basis of a particular object. Once it has been determined which interface definition the object is based on, the message sent from or to the object can be decoded in the decoding phase.
