Abstract
Network Function Virtualization (NFV) is bringing closer the possibility to truly migrate enterprise datacenters into the cloud. However, moving applications from private datacenters to cloud centers is complicated because many of these applications require network-based services: firewalls, IDS, load balancers, etc. Furthermore, network centered applications such as the 3G/4G IP Multimedia Subsystem (IMS) have been excluded from services typically provided by datacenters. NFV makes network functions a first-class citizen, and therefore holds strong promise for both enterprise datacenters and more complex network services (e.g., IMS). However, for a Cloud Service Provider to offer such services, many research questions still need to be addressed: e.g., in order to scale up/down resources to satisfy traffic demands and guarantee QoS, when and where should new virtual network functions be instantiated? How can network configuration be updated on-demand to guarantee service chaining, especially in the events of virtual network function creation and deletion? To enable on-demand management of the datacenter network, traditional Cloud Computing Management must be rethought. In this paper, we introduce the concept of a Network Function Center (NFC): we discuss the expected functionality, the meaning of management in this new context, and present a prototype system that uses genetic algorithms to dynamically distribute server and network resources.
