Network function visualization (NFV) has emerged as a promising paradigm in networking, where the hardware-based middleboxes are replaced with software-based virtualized entities typically running on the cloud to provide specific functionalities. By deploying NFV, network services become more adaptive and cost-effective. Many multicast services such as real-time multimedia streaming and intrusion...
Many multicast services such as live multimedia distribution and real-time event monitoring require multicast mechanisms that involve network functions (e.g., firewall and video transcoding). Network function virtualization (NFV) is a concept that proposes using virtualization to implement network functions on infrastructure building block (such as high volume servers and virtual machines), where...
We present a novel spectrum access scheme for open spectrum networks. Different from existing works, this work considers the scenario that contending secondary users have heterogeneous channel availability. It is proved to be NP hard to find the optimal spectrum assignment in this scenario. To solve this problem, a novel approximation algorithm is proposed which is based on the maximum weighted matching...
