Abstract
This document defines OSPF-xTE, an experimental traffic engineering(TE) extension to the link-state routing protocol OSPF. OSPF-xTEdefines new TE Link State Advertisements (LSAs) to disseminate TEmetrics within an autonomous System (AS), which may consist of multipleareas. When an AS consists of TE and non-TE nodes, OSPF-xTE ensuresthat non-TE nodes in the AS are unaffected by the TE LSAs. OSPF-xTEgenerates a stand-alone TE Link State Database (TE-LSDB), distinct fromthe native OSPF LSDB, for computation of TE circuit paths. OSPF-xTE isversatile and extendible to non-packet networks such as SynchronousOptical Network (SONET) / Time Division Multiplexing (TDM) andoptical networks. This memo defines an Experimental Protocol for the Internet community.
