To Achieve a Security Service Chain by Integration of NFV and SDN

In the last two years, ETSI's NFV Management and Orchestration working group has defined the NFV reference architecture. Network Function Virtualization (NFV) intends to decouple the network function from dedicated network appliance through virtualization technologies. As security is an important issue in the context of NFV environments, but the ETSI NFV architecture didn't involve much about security. Therefore we introducing a solution to meet this requirement. This paper first discuss about the traditional way to implement service chain, and then find an appropriate way to provide security service chain, and proposed an architecture which is based on ETSI NFV architecture combined with SDN to implement security service chain.
