    abstract =  {This document describes the process to build BGP-LS key parameters in Native IP multi-domain scenario and defines some new inter-AS TE related TLVs for BGP-LS to let SDN controller retrieve the network topology automatically under various environments. Such process and extension can expand the usage of BGP-LS protocol to multi- domain, enable the network operator to collect the connection relationship between different AS domains and then calculate the overall network topology automatically based on the information provided by BGP-LS protocol.},
