Summary of this BCP draft This draft fits to the following charter item “Definition of the mechanisms required to determine the route and properties of an established path (tunnel tracing)”. This draft states the problem of GMPLS CSPF path computation Since these attributes are differently understood in an industrial environment (especially between optical and packet transport point of view), the path computation results sometimes vary. tries to provide the guideline to consider GMPLS TE attributes for CSFP path computation at a source node. TE attributes must be dealt with correctly in the case of CSPF path computation considering underlying physical and logical technologies of nodes as well as links. |
