There are a number of SDN & NFV research issues such as the architecture design, SDN or NFV elements, deployments, security, and services. SDN&NFV workshop 2015 solicits previously unpublished research papers in the relevant area. Authors are invited to submit original technical papers covering but not limited to the topics of interest listed below: · SDN architectures, planning, and SDN-oriented elements such as Router, Switch, Gateway · SDN & OpenFlow and open source · NFV infrastructure and hardware acceleration · Control plane architectures and network operating systems for SDN/NFV elements · Forwarding plane abstractions and programmability paradigms · Application programming interfaces, protocols, and programming languages · New applications in the NFV and SDN networks. · SDN/NFV data plane and control plane · Performance evaluation such as scalability, reliability, and faulty resiliency. · Security including security function virtualization, security as a service, dynamic service chaining · SDN/NFV tools · Big Data models and analytics for NFV and SDN · Software-based Integration of computing, storage & networks · Mobile Services, Cloud, and SDN & NFV · Future Enterprise Network and SDN/NFV user cases
