Probe-SDN: A smart monitoring framework for SDN-based networks
2016 Global Information Infrastructure and Networking Symposium (GIIS), 2016Software Defined Networking (SDN) is in the process of revolutionizing the way of managing networks by providing a new way to support current and future services. However, by relocating the control functionality in a remote entity, the measurements' accuracy of the resources' utilization becomes more difficult, which complicates the decision making ...

Sampling is an expensive network resource, because switches and routers are able to sample only a small fraction of the traffic they receive. Modern switches and routers perform uniform packet sampling, which has several major drawbacks: 1) the same flow might be unnecessarily sampled multiple times in different switches; 2) all the flows traversing a ...

To address scalability concerns, hierarchical control plane organization has been proposed for SDN. However, an open question is how such a hierarchy should look like. In this paper, we model the impact of hierarchies on control plane performance and derive an expression for an optimal hierarchical organization for a given network scale.

R-SDN: a recusive approach for scaling SDN
2014 International Conference on Information and Communications Technologies (ICT 2014), 2014Software-Defined Networking provides a clean separation between control plane and data plane. In addition, control plane can configure and manage data plane in a centralized way. However, a centralized control plane introduces a problem in scaling SDN network.

Abstract A full deployment of Software Defined Networking (SDN) paradigm poses multi-dimensional challenges viz., technical, financial and business challenges. Technical challenges of scalability, fault tolerance, centralization guarantees exist. Financial challenges of budget constraints, non-availability of phased transition model exist.

Mobility management in wireless networks has been one of the hot research areas in the last decade. PMIPv6 is a network-based layer 3 mobility management protocol, standardized by IETF. It is considered as a promising solution for resolving issues related to the layer 3 mobility management. However, handover latency in PMIPv6 is not acceptable for real

Rethinking the SDN Abstraction
Proceedings of the first Workshop on Emerging Technologies for software-defined and reconfigurable hardware-accelerated Cloud Datacenters, 2017Software Defined Networking (SDN) greatly simplifies network management and introduces unprecedented flexibility by decoupling control functions from the network data plane. However, such a decoupling also opens a box of various open questions, which are not well addressed, e.g., scalability issues and security concerns. This talk firstly describes the

Proceedings of the third workshop on Hot topics in software defined networking, 2014
Software-defined networking provides flexibility in designing networks by allowing distributed network state to be managed by logically centralized control programs. However, this flexibility brings added complexity, which requires new debugging tools that can provide insights into network behavior. We propose a tool, SDN traceroute, that can query the

QoS guarantee over hybrid SDN/non-SDN networks
2017 8th International Conference on the Network of the Future (NOF), 2017Ensuring dynamic behavior, accountability, and flexible management is required by any traffic engineering solution. Software Defined Networking (SDN), presenting a central management control, is a promising solution in this context. However, the migration to SDN is not straightforward.
