Market liberalisation and increasing demands for the allocation of services which span several networks are pushing every network operator to evolve the way o f i n teracting with peer operators. The Inter-domain Demand Allocation (IDA) process is a very complex task for several reasons: there are di erent actors involved, end-to-end routing must take into account QoS requirements, network resources and information are distributed, etc. In this paper we address the problem of the QoS-based multi-domain routing, and more speci cally a multiagent paradigm for supporting the IDA process is de ned. We s h o w h o w Arti cial Intelligence methods for distributed problem solving supply a compact way to formalise the multi-domain routing process, and how this formalism enables an agent middle-ware to route demands across distinct domains.

We present an application of evolutionary-fuzzy prediction in inter-domain routing of broadband network connections with Quality of Services requirements in the case of an integrated ATM and S D H networking architecture. The higher-layer nature of inter-domain routing requires to review the whole routing process in order to maximize performance at low decision making cost, a clear case for fuzzy-set logic based algorithms. In order t o probabilistically avoid shortage of resources, besides effectively computing the feasible paths for an incoming connection request, under uncertainty, these paths should be compared in terms of the negative impact in resource supply which may be caused by other connections. To do this, besides enriching the protocol with vectors of per-class shadow cost metrics, quantized using fuzzy-set theory, we used a subset-interactive autoregressive time-series predictor which is based on fuzzy measures to evaluate path costs under supply metrics that change over time. Moreover, as the connections we are dealing with are semi-permanent, we must take into account the connections lifetime. The complete system is part of the MISA Management of Integrated SDH and ATM network architecture and will be implemented and evaluated in the global broadband connection service of the pan-European test-bed.
