PATH COMPUTATION ELEMENT AND METHOD FOR SETTING PATH OF USER NETWORK INTERFACE

摘要

The present invention relates to a path computation device according to a transport network assigned (TNA) address, and a user network interface (UNI) based path computation method. The path computation device and a user network based path computation method according to the present invention minimize overhead due to an abstract traffic engineering (TE) link, a hand-operated configuration to be formed in advance, and routing information exchange between local domains or inter-domains, and an advertisement thereof.
