Biochemically-inspired method for constructing service space in virtualized network system

In virtualized network system, multiple services are located on virtual and physical servers for constructing service space, and these servers provide the services according to user requests. For ensuring the scalability of the system, and for quick detection and recovery of system failures in such large-scale system, we need to construct the service space in an autonomous distributed fashion. In this report, we propose a construction method of service space based on chemical-inspired spatial coordination model. We model a server as a tuple space, and chemical substances in the tuple space as server resources, service demands and user requests. Chemical reactions are defined in the tuple space to describe various behaviors in the server. We confirm the behavior of the proposed method by simulation experiments. Furthermore, we present the application scenario of the proposed method to placing functions and determining packet flow routes in Network Function Virtualization (NFV) architecture to confirm the suitability of the proposed method for actual network services.
