Abstract:

A methodology for determining the common attributes of two systems or entities is shown. This methodology includes a content independent options negotiation. Tree structures are defined for each entity or system. These tree structures include relational operators and attributes. The tree defining the relational operations and attributes is installed within each entity. For initiating communications between entities, each entity sends its own tree and receives the other system's tree. Comparison analysis is then performed upon the trees to determine where they intersect or match. Matching attributes may indicate that communications between entities may take place.
