METHOD AND APPARATUS FOR CREATING VIRTUAL TRAFFIC ENGINEERING LINK

摘要

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.

1. A method of creating a virtual traffic engineering (TE) link, performed at a first node of an optical transport network (OTN), the method comprising:
determining to create a virtual TE link that connects the first node and a second node in an upper layer of the OTN: setting up a forwarding adjacency (FA)-label switched path (LSP) between the first node and the second node on a control plane of an OTN layer to create the virtual TE link; and creating the virtual TE link by registering the setup FA-LSP as a TE link of the upper layer of the first node.
