Abstract: Highlights•We study the problem of energy-efficient orchestration of SFC requests across multiple domains.•We extend node aggregation to construct a domain-level graph of the substrate network.•We propose an energy-efficient algorithm to orchestrate SFC requests across multi-domains.•We implement our proposed algorithm and compare it with existing algorithms.
