Interface definitions of topology elements and AspectJ aspect definitions for helper methods around performing common operations while working with topology entities.

Implementation of a Topology Provider that stores the necessary topology entities in a PostgreSQL database. Implementation based on Eclipselink JDO ORM and can be adapted to multiple backend databases.

Implementation to import topologies as specified in various external formats. Currently, supports importing from SNDLib (https://sndlib.zib.de).

Notifications are generated via aspects on various topology operations, and handlers can be attached to process these notifications in an asynchronous fashion. This module includes implementations of these notifications handlers.

An in-memory implementation of the topology elements providing a mechanism to import and operate on network topologies in small-scale applications.
