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.
