Telecommunication networks are now an interconnection of competitive operators that need to cooperate to ensure end-to-end delivery of traffic. Inter-domain agreements have to be performed, and pricing is seen as a relevant way to reward intermediate domains for forwarding the traffic of others and such that the network can be efficiently self-managed, as decentralized as possible. In the devoted literature, Vickrey-Clark-Groves (VCG) auctions have been highly considered because they provide proper incentives, lead to an efficient use of the network and verify other relevant characteristics. On the other hand, it has been highlighted in this specific context that they are neither budget-balanced nor robust to collusion. After reviewing the list of properties that we ideally would like the inter-domain pricing to verify and the fact that no mechanism can have them all together. We then discuss the properties that could be relaxed. Furthermore, we present related works on pricing and resource allocation especially devoted to inter-domain pricing, and discuss how they can be applied to our specific problem and what are the corresponding results.
