NGL01-1: Least Cost Routing in Inter-Carrier Context

Carriers conveying long-distance traffic face different routing options with regard to service quality and cost. Thus, least cost routing (LCR) solutions supporting optimal decisions become a very important issue in the inter-carrier operations. In this paper, we present this problem in the context of the long-distance traffic partner-carrier choice. The mathematical optimization problem is formulated. Especially, constraints (e.g., capacity, volume) related to the techniques used are considered. Different tariff formulations are taken into account as well.
