Abstract
Abstract: Service chaining is one of the challenges in network function virtualization (NFV), where a sequence of middleboxes apply their service to particular traffic. The challenge of service chaining is that a middlebox may alter the content of packet headers; thus, the context of service chaining for particular traffic gets lost. This paper proposes Segmented Proactive Flow Rule Injection (SPFRI) using Software Defined Networking (SDN). SPFRI maintains the consistency of service chain even though one or more middleboxes may ...
