A Selfish Service Chaining Scheme for Minimizing Service Path Delay in NFV Networks
Ryohei Kokura, Masahiro Sasabe, Shoji Kasahara (NAIST) NS2022-95
Abstract (in Japanese) (See Japanese page) 
(in English) Network functions virtualization (NFV) can flexibly achieve various network services by running network functions as software on generic hardware. In NFV networks, a network service can be realized as a service chain, which is a sequence of virtual network functions (VNFs). When a new service chain request arrives at the NFV network, an NFV orchestrator solves a service chaining problem by constructing a special path, called a service path, from the source to destination, which satisfies both the capacity constraints on nodes and links as well as executing the VNFs in order. In this paper, focusing on the situations with multiple service brokers, we propose a selfish service chaining where each service broker tries to select a service path to minimize its own service path delay in a distributed manner. Through simulation experiments, we show the proposed method can achieve low-latency service paths with exponential rate of convergence.
