摘要:
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.
摘要:
A data network, method and a computer program product, wherein the data network is implemented by a first network level (104) having a first addressing scheme and at least a second network level (108) 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.

摘要:
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.
