Towards an elastic distributed SDN controller

Towards a carrier SDN: an example for elastic inter-datacenter connectivity.

We propose a network-driven transfer mode for cloud operations in a step towards a carrier SDN. Inter-datacenter connectivity is requested in terms of volume of data and completion time. The SDN controller translates and forwards requests to an ABNO controller in charge of a flexgrid network.

SDN Controller for LTE Networks

LTE (Long Term Evolution) networks are capable of handling tremendous user loads with the current user base estimated to be in hundreds of millions. LTE is superior to older telecommunication networks, yet it suffers from issues like inflexible & expensive equipment, complex control plane protocols, coupling of control and data planes in devices and equipments and so on. It is therefore decided...

Loose Management for Multi-controller in SDN

SMaRtLight: A Practical Fault-Tolerant SDN Controller

The increase in the number of SDN-based deployments in production networks is triggering the need to consider fault-tolerant designs of controller architectures. Commercial SDN controller solutions incorporate fault tolerance, but there has been little discussion in the SDN literature on the design of such systems and the tradeoffs involved. To fill this gap, we present a by-construction design...

Tools for a Multi-Controller SDN Architecture

Software Define Network (SDN) is a recent paradigm based on the separation between the data plane and the control plane, allowing to handle the traffic network by means of software. The SDN ecosystem is fragmented due to the multitude of different controller platforms. This creates a danger of a controller lock-in for SDN application developers and for SDN network operator. In order to tackle t...
