Architecture for inter-domain service delivery

Facing demands for high performance services, network operators are challenged by upgrading the level of management of their networks. But providing inter-domain Quality of Service (QoS) guaranteed services has to bring incremental revenues to the involved operators realizing needed evolutions of their network infrastructures. Beside these upgrades, operators are not ready to disclose information (e.g. network topologies and capacities) that would simplify the process of establishing end-to-end QoS guaranteed connection. In previous works, we have proposed and defined the notion of network operator alliance. Such an alliance would regroup operators which would find interest in cooperating and where some administrative costs would be shared and revenues split so that incentives to deliver inter-domain QoS guaranteed services would be met. Furthermore, confidentiality and business rules would be determined by the alliance participants. In a previous work [PDDS09], we proposed an architecture for inter-domain service delivery which includes extensions for Operation Support Systems (OSS) and control planes. This paper depicted the implementation of this architecture that covers network management at different plane levels and which has been tested with 5 emulated networks in our lab.
