Cloud computing: state-of-the-art and research challenges
TLDR
A survey of cloud computing is presented, highlighting its key concepts, architectural principles, state-of-the-art implementation as well as research challenges to provide a better understanding of the design challenges of cloud Computing and identify important research directions in this increasingly important area.
Network Function Virtualization: State-of-the-Art and Research Challenges
TLDR
The state-of-the-art in NFV is surveyed, promising research directions in this area are identified, and key NFV projects, standardization efforts, early implementations, use cases, and commercial products are overviewed.
Virtual Network Embedding with Coordinated Node and Link Mapping
TLDR
This paper formulate the VN em- bedding problem as a mixed integer program through substrate network augmentation, and devise two VN embedding algo- rithms D-ViNE and R- ViNE using deterministic and randomized rounding techniques, respectively.
ViNEYard: Virtual Network Embedding Algorithms With Coordinated Node and Link Mapping
TLDR
A collection of VN embedding algorithms that leverage better coordination between the node mapping and link mapping phases and show that the proposed algorithms increase the acceptance ratio and the revenue while decreasing the cost incurred by the substrate network in the long run.
Network virtualization: state of the art and research challenges
TLDR
The past and the state of the art in networkvirtualization along with the future challenges that must be addressed to realize a viable network virtualization environment are investigated.
Orchestrating Virtualized Network Functions
TLDR
Trace driven simulations on realworld network topologies demonstrate that the heuristic can provide solutions that are within 1.3 times of the optimal solution and suggest that a VNF-based approach can provide more than 4× reduction in the operational cost of a network.
PayLess: A low cost network monitoring framework for Software Defined Networks
TLDR
This paper utilizes the Floodlight controller's API to implement the proposed PayLess - a monitoring framework for SDN that uses an adaptive statistics collection algorithm that delivers highly accurate information in real-time without incurring significant network overhead.
Data Center Network Virtualization: A Survey
TLDR
A survey of the current state-of-the-art in data center networks virtualization, and a detailed comparison of the surveyed proposals are presented.
Conflict classification and analysis of distributed firewall policies
TLDR
All anomalies that could exist in a single- or multifirewall environment are identified and a set of techniques and algorithms to automatically discover policy anomalies in centralized and distributed firewalls are presented.
