A data network, method and a computer program product, wherein the data network is 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 provides connectivity over at least one network domain. A first group of Network Resource Managers, NRMs, (b-d)) is arranged to control the resources of the first network level and a second group of NRMs (e-g) is arranged to control the resources of the second network level. The NRMs of the first group (b-d) and second group (e-g) exchange resource requests by using the first addressing scheme and the NRMs (e-g) of the second group perform an address mapping between the first and second addressing schemes.

Arrangements and method for hierarchical resource management in a layered network architecture

The present invention relates to a method and arrangement for providing end-to-end Quality of Service within a mobile telecommunication system. The communication system comprises at least one network e.g. a Core Network (CN) and at least one Radio Access Network (RAN) for Internet Protocol (IP) based transmission, wherein a Network Resource Manager (NRM) comprising a resource map is monitoring and/or controlling resources within the IP network.

Network resource manager in a mobile telecommunication system

A method and arrangement in a communications network. The object is to provide a way of handing recourse management issues and admission control within an IP telephony system. The object is achieved by a topology aware resource manager collecting routing information concerning the IP network, obtaining resource information concerning resources within the IP network, creating a resource map by combing the routing information and resource information, and performing recourse management issues and admission control within the system by the resource map and by interacting with a gatekeeper.

Method for, and a topology aware resource manager in an IP-telephony system

Method in a packet based communication network including network domains to establish a virtual leased line (VLL) between a source (SRC) and a destination (DST) in different domains in order to achieve packet transfer between the source and the destination, wherein a bandwidth broker (BB) is associated to each network domain.
