Node in a transport network that adds time dependent data to traffic engineering data

摘要

#CMT# #/CMT# The node (N1) has a processing unit (MT) adding temporal data to traffic engineering data e.g. network topology, representing forecast performances e.g. maximum passband, of a link of a transport network e.g. generalized-multi protocol label switching (G-MPLS) network. The temporal data represents a future period during which the engineering data is valuable. The unit (MT) sends routing protocol messages, having the engineering and temporal data, to nodes (N2- N6). The unit (MT) stores the temporal data corresponding to the engineering data in a traffic engineering database (BD1). #CMT#USE : #/CMT# Node e.g. input/output peripheral router and intermediate router, that is used in a transport network (claimed) such as Internet protocol/generalized-multi protocol label switching (G-MPLS) type network, GPLS network and GMPLS network. #CMT#ADVANTAGE : #/CMT# The utilization of the temporal data and the traffic engineering data in the processing unit of the node allows to calculate connection paths for immediate utilization and temporary connection paths for future utilization. The node facilitates the reservation of resources and the calculation of connection paths in the transport network #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a functional and schematic view of a part of a transport network.
