Abstract: A Generalized-Multi-Protocol Label Switching controlled network is described, as is a method for managing services in the network under conditions of disrupted control plane connectivity. Nodes of the network use a Resource Reservation Protocol with Traffic Engineering extension, RSVP-TE, to allocate and provision resources of the network. Each of the nodes is adapted to evaluate local RSVP Path or Resv state data after having sent at least one signaling message to a receiving neighboring node without receipt of an acknowledgement message from said receiving node within a configurable time to determine an IP address of a node being located after the non-responsive receiving node along a service path of a service in a downstream or upstream direction. Each node is adapted to send the signaling message to the determined IP address of the next node located behind the non-responsive receiving node along the service path.

Abstract: A network with a network wide extended policy framework comprising: path computation clients (PCCs), associated with at least one local policy enforcement point (PEP); path computation servers (PCSs), associated with at least one policy decision point (PDP). The PEPs and PDPs adapted to exchange attributes determined by at least one PDP. PDPs are adapted to identify network elements/network services requiring identical configuration parameters by evaluating parameters advertised in the network and update policy related to identified groups in case of configuration error. Updated policy is distributed by PDP in policy notification to PEPs associated with network elements/network services of identified group. The PEPs receiving policy notification comprising updated policy from PDP adapted to translate the updated policy into configuration settings of network elements/network services the identified group.
