What is a Fog Node A Tutorial on Current Concepts towards a Common Definition
Eva Marin Tordera, Xavi Masip-Bruin, Jordi Garcia-Alminana +4
Fog computing has emerged as a promising technology that can bring the cloud applications closer to the physical IoT devices at the network edge. While it is widely known what clou…
VNF Placement with Replication for Load Balancing in NFV Networks
Francisco Carpio, Samia Dhahri, Admela Jukan
Network Function Virtualization (NFV) is a new paradigm, enabling service innovation through virtualization of traditional network functions located flexibly in the network in form…
On the IP Traffic Matrix Problem in Hybrid SDN/OSPF Networks
Marcel Caria, Admela Jukan
IP networks with a hybrid control plane deploy a distributed routing protocol like OSPF and the centralized paradigm of SDN in parallel. The advantages and disadvantages of a hybri…
Link Capacity Planning for Fault Tolerant Operation in Hybrid SDN/OSPF Networks
Marcel Caria, Admela Jukan
Link capacity dimensioning is the periodic task where ISPs have to make provisions for sudden traffic bursts and network failures to assure uninterrupted operations. This provision…
DiffFlow: Differentiating Short and Long Flows for Load Balancing in Data Center Networks
Francisco Carpio, Anna Engelmann, Admela Jukan
In current Data Center Networks (DCNs), Equal- Cost MultiPath (ECMP) is used as the de-facto routing protocol. However, ECMP does not differentiate between short and long flows, th…
Defragmentation-as-a-Service (DaaS): How beneficial is it?
Sandeep Kumar Singh, Wolfgang Bziuk, Admela Jukan
We analyze Defragmentation-as-a-Service (DaaS) in elastic optical networks and show that the positive effect of defragmentation depends on the rate at which it is performed, load (…
Balancing Data Security and Blocking Performance with Spectrum Randomization in Optical Networks
Sandeep Kumar Singh, Wolfgang Bziuk, Admela Jukan
Data randomization or scrambling has been effectively used in various applications to improve the data security. In this paper, we use the idea of data randomization to proactively…
SDN Partitioning: A Centralized Control Plane for Distributed Routing Protocols
Marcel Caria, Admela Jukan, Marco Hoffmann
Hybrid IP networks that use both control paradigms - distributed and centralized - promise the best of two worlds: programmability and agility of SDN, and reliability and fault tol…
