Abstract:
A method of recovering a fault in a multilayer network and an apparatus thereof are provided, the method including obtaining lower layer backup path setting information through a signaling message that is used for a label based path setting, setting a backup path at a lower layer based on the obtained lower layer backup path setting information, and upon detecting a fault at the lower layer, performing a protection switching through the set backup path at the lower layer.
Abstract:
A user network interface (UNI) path setting method includes advertising an attribute and state information of a TNA interface, and updating a database using information collected through the advertising, computing a path to a destination TNA address from a source TNA address satisfying UNI path setting parameter information included in a path message in consideration of an attribute and state information of the updated TNA interface/link when receiving a path setting request message from an operator, transmitting a path message to a destination through a network based on the computed path, and transmitting a reservation (RESV) message for UNI path generation to a source through the network when normally receiving, by the destination, the path message.
