Virtual Link Embedding in Collaborative Sliced Multi-Administrative Multi-Domain Networks
Résumé
When providing services in multi-administrative multi-domain
networks, domains usually disclose a topology aggregation
composed of a set of abstract links connecting their border nodes.
Such an aggregation is motivated by the will of limiting the
information exposed to other domains. This, however, leads to
inefficient resource usage. In order to enable effective
collaborations between domains, in this paper, we propose to enrich
the topology aggregation exposed by domains by promoting the
inclusion of abstracted non-border network nodes and the network
slices supported by each domain. Our evaluations on real and
random topologies show the significant potential gains in terms of
admission ratios and resource usage that such additions bring.
