The HaDiNet network interconnects roughly 1000 student rooms, currently using a single LAN. This network will now be upgraded to give each user a separate /29 IP subnet routed to his room. In the case that users require larger subnets, it should be easy to route another subnet to a room. Therefore, management software is required to configure the network.
Currently, the HaDiNet uses a star topology, with the core switch situated in the K3 building and other routers connected to it with 1Gbit fiber links. However, interconnection of the edges of this star is planned. Soon, all switches will be able to route IP packets. Essentially, they are giant routers with enormous backblane and routing capacity (at least to me, being a network newbie, it's pretty impressive).
In a perfect world, the central management software would put each room into a separate VLAN, attach the router closest to the actual room to that VLAN (basically, let the switch that the port leading to the room is on also be the gateway router for
