Methods and system for checking connectivity of physical layer Lable Swtiched Path in GMPLS based network

摘要

Provided is a method and system for confirming label switched path (LSP) connection in a global multi-protocol label switching (GMPLS)-based network. The method includes: collecting LSP hierarchy information; selecting one of a plurality of paths between first and second clients according to the LSP hierarchy information; and confirming the connection of the selected path.
