  • Abstract: Propelled by the emergence of new technologies like software defined networking and network function virtualization, the recent trend towards network softwarization is currently transforming the way network services are provisioned and managed and opens the door for a new breed of cloud service offerings. Specifically, cloud providers have now the enabling technologies to offer “network chains” as a service where customers could require their traffic to go through a service chain made out from an ordered sequence of several network functions. In this context, a daunting challenge for cloud providers is to assess the real resource requirements and costs of different types of network functions and to efficiently place the service chain components into the physical infrastructure while achieving several conflicting objectives related to performance, service level agreements, scalability, and revenue. In this talk, we will focus on understanding the research challenges related to the provisioning and deployment of network chains as a service in large-scale cloud infrastructures. We will also provide a characterization of the resource requirements and potential costs of virtual network functions and highlight the key challenges introduced by them. We will then present our recent work towards addressing some of these challenges.
