The AutoBAHN system aims at providing a guaranteed capacity, connection-oriented service between two end points. Due to the distributed nature of the system and the fact that AutoBAHN has access to critical parts of the network, the importance of a robust, secure and dynamic mechanism for handling and distributing topology information cannot be underestimated. We will present how AutoBAHN manages to create an abstract representation of the physical network topology by hiding information such as IP addresses, port values, VLAN, MTU, link capacities etc., how this abstract topology is merged among domains and how AutoBAHN system handles topology changes in terms of their influence on reservation processing.</p>
