MeshRouter Primitives: Messages, Interest, and Interpreters

Abstract

The MeshRouter architecture provides a general framework for interest-limited message ex- changes among client processes. There are two general areas in which the MeshRouter im- plementation depends on specics of the associated clients: i) the lowest level inter-processor communications model and ii) the nature/content of exchanged messages and \interest". This note describes the hierarchical object design (C++ sense) used to implement the basic Message and Interest objects of the MeshRouter. Interfaces are dened in terms of abstract base classes, and specific inherited objects appropriate for the RTI-s/JSAF application are presented as concrete examples. The MeshRouter system includes a substantial memory management com- ponent for efficient use of the basic Message objects. This system is summarized and plausible near-term extensions are noted.
