ZTE Corporation ZTE Corporation ZTE Corporation The Generalized Multi-Protocol Label Switching (GMPLS) suite of protocols has been defined to control different switching technologies as well as different applications. These include support for requesting Time Division Multiplexing (TDM) connections including Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) and Optical Transport Networks (OTNs). Along with the development of technology, some new routing requirements which are addressed in G.7715.1 emerge. This document concentrates on the new routing requirements addressed in G.7715.1 and placed on the GMPLS suite of protocols in order to support the capabilities and functionalities of an Automatically Switched Optical Network (ASON) as defined by the ITU-T.
