Method for providing topology awareness information within an ip network
First Claim
1. A method for providing topology awareness information within an IP network, said IP network comprises a central node (502) of a topology awareness system (500) that is adapted to store and process topology information, said central node (502) is connected to at least one topology awareness unit (P) that is implemented in a router (504) within said IP network, said unit comprises the functionality of a topology awareness system interface (402), wherein the method comprises the steps of:
- transmitting a registration message from one of the topology awareness units (P) to the central node (502), adding an identity of said unit (P) to a list of known units (P) at the central node (502), and transmitting a response message from the central node (502) to the unit (P), wherein said response message has at least the capability to order the unit (P) to;
keep the current relation with the central node (502), if the current relation between the unit (P) and the central node (502) is accepted;
aggregate, if the central node (502) determines that the unit (P) is to be used as an aggregation point;
or redirect to a previous aggregation point, if there exist a suitable aggregation point.

Abstract
A method, a unit and a computer program product for providing topology awareness information within an IP network includes a central node and a plurality of routers, wherein the probe is implemented in a router within the IP network and the probe belongs to a topology awareness system, that includes: elements for obtaining and maintaining relationship with other probes within the IP network, elements for collecting information about other network elements e.g. routers and switches, elements for communicating topology information with the central node of the topology awareness system, and elements for obtaining information concerning local resources on the router where the probe is implemented.
