Outline of Final Research Achievements

In Network Function Virtualization (NFV), various Virtual Network Functions (VNFs) are deployed on general purpose servers. To operate the NFV system, placement of VNFs on servers, resource allocation to each VNF, and flow routes are determined adaptively. Furthermore, to respond to environmental fluctuations, and to maintain the scalability of the NFV services, a distributed control is more feasible than a centralized one. One way to achieve such behaviors is to exploit a biochemical mechanism with autonomous dispersibility and self organization.
In this work, we has proposed a construction method of service space in virtualized network system based on biochemically inspired tuple space model. In this method, the behaviors in the virtualized network system are described by biochemical reactions in tuple spaces. To operate the NFV system, the method has been extended to handle flow routes in accordance with SFC requests, and server resource limitation.
