Abstract: Provided is a method and apparatus for creating a virtual traffic engineering (TE) link in an upper layer of an optical transport network (OTN). To create a virtual TE link, a node may determine to create the virtual TE link in an upper layer of an OTN, and may set up a forwarding adjacency (FA)-label switched path (LSP) between nodes in an OTN layer. The FA-LSP may be set up on a control plane of the OTN layer. The node may create the virtual TE link by registering the setup FA-LSP as a TE link of the upper layer of the node.

Abstract: Provided herein is a link management method and apparatus in a multi-layered network, the method including confirming whether or not set virtual TE link resources can be committed to a virtual TE (traffic engineering) link; in response to the set virtual TE link resources being committable to the virtual TE link, committing the resources to the virtual TE link through resource commitment; in response to the set virtual TE link resources being not committable to the virtual TE link, determining whether or not the virtual TE link is an adaptive virtual TE link; and in response to the virtual TE link being determined as the adaptive virtual TE link and the adaptive bandwidth satisfying TE link setting standards, committing the resources to the virtual TE link.

Abstract: Provided herein is a path computation element based on Transport Network Assigned (TNA) address and a method for path computation based on User Network Interface (UNI). The path computation element and UNI based path computation method of the present disclosure minimize overhead caused by abstract Traffic Engineering (TE) link, and minimize manual environment set up, and routing information exchange and advertisements in a local domain or between domains.
