Abstract:
1. A method in a data network implemented by a first network level having a first addressing scheme and at least a second network level having a second addressing scheme, each network level providing connectivity over at least one network domain, the method comprising the steps of: controlling resources of the first network level by a first group of Network Resource Managers (NRMs); controlling resources of the second network level by a second group of NRMs, wherein the first group and the second group of NRMs comprise means for communicating on a common network level; exchanging resource requests between the NRMs of the first and second groups using the first addressing scheme, the NRMs of the first group and the second group admitting new resource requests based at least in part on a total amount of available resources, an amount of resources currently reserved by previous reservations, and an amount of resources requested in the new resource requests; and performing an address mapping between the first and second addressing schemes so that a set of resources that is used by a reservation in the second group, controlled and known by the second group, is aggregated into a single resource in the first group of NRMs.
