Abstract
A network element includes a processing system for supporting inter-area data transfer paths which are Border Gateway Protocol load sharing data paths. The processing system maintains usage attributes expressing whether a given inter-area data transfer path is to be used for servicing a given traffic category. The processing system recognizes a traffic category of a data frame to be forwarded on the basis of for example the Quality-of-Service class of the data frame. Thereafter, the processing system selects one of the inter-area data transfer paths at least partly on the basis of the usage attributes and the recognized traffic category, and forwards the data frame to the selected inter-area data transfer path. Therefore, Border Gateway Protocol load sharing can be utilized for providing for example Quality-of-Service class differentiated traffic engineering.
