OSPF-TE is an extension to OSPF extending the expressivity to allow for traffic engineering and use on non-IP networks (RFC 3630)[6]. More information about the topology can be exchanged using opaque LSA carrying type-length-value elements. These extensions allow OSPF-TE to run completely out of band of the data plane network. This means that it can also be used on non-IP networks, such as optical networks.
OSPF-TE is mainly used within GMPLS networks, as a means to describe the topology over which GMPLS paths can be established. GMPLS then uses its own path setup and forwarding protocols, once it has the full network map.
