“…In recent years, some important steps supporting source routing have been made. The authors of [14] introduced a distributed inter-ISP service plane, which is coupled with a Path Computation Element (PCE) based control plane. In their framework, routing is source-based at the AS-level and distributed at the router-level.…”

SUMMARYAs interdomain routing protocol, BGP is fairly simple, and allows plenty of policies based on ISPs' preferences. However, recent studies show that BGP routes are often non-optimal in end-to-end performance, due to technological and economic reasons. To obtain improved end-to-end performance, overlay routing, which can change traffic routing in application layer, has gained attention. However, overlay routing often violates BGP routing policies and harms ISPs' interest. In order to take the advantage of overlay to improve the end-to-end performance, while overcoming the disadvantages, we propose a novel interdomain overlay structure, in which overlay nodes are operated by ISPs within an ISP alliance. The traffic between ISPs within the alliance could be routed by overlay routing, and the other traffic would still be routed by BGP. As economic structure plays very important role in interdomain routing, so we propose an effective and fair charging and pricing scheme within the ISP alliance in correspondence with the overlay routing structure. Finally, we give a simple pricing algorithm, with which ISPs can find the optimal prices in the practice. By mathematical analysis and numerical experiments, we show the correctness and convergence of the pricing algorithm.

“…The instantiation of service is done through a check on the resource availabilities. In [5] we suggest providing, in instantiation and activation messages, a common service identifier (SID) in order to identify end-to-end service during its whole life cycle. The service layer then transmits the element information to the policy manager, which constructs a filter for the service request.…”

“…Using this path, each domain signalizes the reservation on its internal routers. In a (G)MPLS network, this signalization can be proceeded using RSVP-TE [3] as suggested in [5]. If the reservation succeeds, a domain sends an "activation ok" message to the third party.…”

“…Other authors and consortiums [1,4,6,16] have recommended alternative approaches, based on the assumption that the inter-AS service establishment question has to be solved at a business level, using QoS contracts (SLAs). Such contracts are then mapped to the actual network resources.…”

Multimedia services and other critical multisite services (e.g., VPN) are becoming mainstream, and they require a guaranteed quality of service (QoS). Services need to be established across several autonomous systems (ASes), often to connect end-users. Thus, provisioning and control of end-to-end QoS requirements arise as one of the main challenges in inter-AS management. The contractual approach, consisting in using service-level agreements (SLAs) defined by each crossed AS, allows to negotiate contract chains that satisfy end-to-end requirements. However, establishing such chains by on-demand negotiations does not scale up for large numbers of requests. Hence, we propose a negotiation process to occur before users' requests to establish service are received. The proposed negotiation process results in the selection of aggregated contract chains, called pipes, and a distribution between them. Such a distribution would indicate, for each chain of a pipe, the connection flow it may accept. In this paper, we address the pipe negotiation problem as a network flow problem. We also propose a distributed adaptation of an algorithm for network flow problems.
