SOFTNETWORKING 2017 - International Symposium on Advances in Software Defined Networking and Network Functions Virtualization

The Symposium is dedicated tadvances and challenges in SDN&NFV technologies and their applications.
Software-Defined Networking (SDN) is a recent architectural and technological approach that decouples the network control and data planes. It separates the network control logic from the underlying routers and switches by logically centralizing the network control in SDN controllers and implementing the traffic forwarding in switching hardware. SDN offers network programmability capabilities, applicable in a flexible way. SDN introduces novel abstractions in networking, thus simplifying network management and facilitating faster network evolution. SDN is natively based on virtualization. Via service orchestration, the applications can automatically reconfigure the network and simultaneously optimize the user experience, application performance and network resource utilization.
Network Function Virtualization NFV is an emergent technology promoted recently (mainly by the telecom world), having as major objective timprove the capital efficiencies vs. traditional dedicated HW implementation solutions, by using COTS HW, tprovide Virtualized Network Functions (VNFs) through SW virtualization techniques. Among its specific objectives are: sharing of HW and reducing the number of different HW architectures; timprove flexibility in assigning VNFs tHW (better scalability, decoupling functionality from location, enabling time of day reuse, enhancing resilience through virtualization, and facilitating resource sharing); rapid service innovation through SW-based service deployment; common automation and operating procedures; reduced power usage; standardized and open I/Fs between VNFs infrastructure and management entities.
SDN approach can support or is applicable in various contexts: clouds/data centres; enterprise; WANs, cellular/mobile, wireless, home, sensors ? networks; network and resources management, security; traffic and QoS management, media and content distribution. New areas of applications have targets in M2M, wireless and 5G networks. The 5G core network will most proba¬bly utilize the ongoing evolution in SDN and NFV tprovide a high level of flex¬ibility and scalability when supporting different 5G deployments with a com¬mon toolbox of network functions. While still in early stage, SDN is moving very fast towards its adoption in the industry and by the operators, but it still has open research issues.
NFV applications and use cases are oriented towards several areas (but not only): Home environment; Mobile Core&IMS; Mobile base stations; Fixed access networks; CDNs; flexible service offering through NFVIaaS, VNFaaS, VNPaaS, VNF flexible Forwarding Graphs.
SDN and NFV could be implemented independently; however, they are more and more seen as complementary technologies that can cooperate in complex systems. This open research issue is an important topic of the symposium.
