MULTI-LEVEL LINK MANAGEMENT APPARATUS, MULTI-LEVEL INTEGRATED NETWORK TRANSMISSION SYSTEM AND MULTI-LEVEL LAYER LINK MANAGEMENT METHOD

摘要

A multi-level link management apparatus, a multi-layer integrated network transmission system and a multi-level link management method are disclosed. The multi-level link management apparatus according to an embodiment of the present invention constructs an integrated traffic engineering link on one control plane in a multi-level network, performs real time monitoring and integrated management for a link failure and performance for each level, and notifies a neighboring node of the failure and a performance lowering state of the multi-level link and performs integrated management. Therefore, the present invention enhances reliability of the multi-level network and monitors the failure and the performance lowering in real time, thereby making performance diagnosis and management of the system and reducing path protecting and switching time.;COPYRIGHT KIPO 2015
