EnforSDN: Network policies enforcement with SDN

Yaniv Ben-Itzhak, Katherine Barabash, Rami Cohen, Anna Levin, Eran Raichstein

SDNFV: Flexible and Dynamic Software Defined Control of an Application- and Flow-Aware Data Plane [article]

Wei Zhang, Guyue Liu, Timothy Wood, K.K. Ramakrishnan, Jinho Hwang
2016 arXiv   pre-print
However, the current divide between an intelligent control plane and an overly simple, stateless data plane results in the inability to exploit the flexibility of a software based network.  ...  In this paper we propose SDNFV, a framework that expands the capabilities of network processing-and-forwarding elements to flexibly manage packet flows, while retaining both a high performance data plane  ...  Stratos [37] steers flows between available middleboxes by using an ILP formulation which considers a binary cost function between middleboxes.  ...

Virtual function placement and traffic steering in flexible and dynamic software defined networks

Ali Mohammadkhan, Sheida Ghapani, Guyue Liu, Wei Zhang, K. K. Ramakrishnan, Timothy Wood
2015 The 21st IEEE International Workshop on Local and Metropolitan Area Networks  
A key problem is how and where network functions should be placed in the network and how traffic is routed through them.  ...  In this paper, we formulate the problem of network function placement and routing as a mixed integer linear programming problem.  ...  One consequence is that it lacks the dynamic nature of placing NFVs in the network and the corresponding routing. 2) Stratos [9] : Stratos is an orchestration layer for virtual middleboxes in clouds.  ...

SCM: A method to improve network service layout efficiency with network evolution

Qi Zhao, Chuanhao Zhang, Zheng Zhao, Xiangxiang Zeng
2017 PLoS ONE  
Network services are an important component of the Internet, which are used to expand network functions for third-party developers.  ...  Regarding this problem, this paper proposes a service chain migration (SCM) method with the framework of "software defined network + network function virtualization" (SDN+NFV), which migrates service chains  ...  [23] proposed an energy-aware virtual machine migration method in a cloud environment to improve the efficiency and decrease the energy consumption of the network.  ...
