System and method for reporting out-of-resources (oor) conditions in a data network

A first node comprising:

• a memory containing an advertisement message having one or more type-length-value (TLV) objects including a plurality of indicators each corresponding to a respective differentiated services traffic engineering (DS-TE) class, each indicator configured to report one or more out of resource (OOR) conditions of an entity for the respective DS-TE class, the one or more OOR conditions indicating the node will reject a new label switched path (LSP);
• and
• a processor configured to report the one or more OOR conditions on the entity for the particular DS-TE class in the one or more TLV objects to a second node to cause the second node to avoid using the entity in the new LSP of the particular DS-TE class.

A non-transitory computer-readable storage medium including instructions for reporting an entity is out of resources (OOR), the instructions when executed by a processor of a computing device causing the computing device to:

• generate, at an intermediate node contained in a data network, an advertisement message having one or more type-length-value (TLV) objects including a plurality of indicators each corresponding to a respective differentiated services traffic engineering (DS-TE) class, each indicator configured to report one or more OOR conditions of the entity for the respective DS-TE class, the one or more OOR conditions indicating the intermediate node will reject a new label switched path (LSP);
• and
• report the one or more OOR conditions on the entity for the particular DS-TE class in the one or more TLV objects to a head-end node to cause the head-end node to avoid using the entity in the new LSP of the particular DS-TE class.
