“…A multitude of controllers exists on the market, differentiated by the platform, the vendor, the application programmable interface (API) or the language support [22]. Our analysis of vendors, projects and implementations reveals 28 open source controller and 64 commercial SDN controller and vendors.…”

The evolution of virtualization techniques is changing operating principles in today's datacenters. Virtualization of servers, networks and storage increases the flexibility and dynamic of the environment by reducing the administrative overhead. Based on a physical underlay network, different logical networks are implemented with new protocols like VXLAN, STT or GENEVE. New paradigms like Software-Defined-Networks or Network Function Virtualization offer new capabilities to redesign the whole network infrastructure. This trend creates new challenges for digital investigations analysing incidents by extracting and interpreting recorded data inside the environment. As a branch of digital investigation, network forensic investigation is used to examine network traffic by capturing the data of a suspicious target system and analysing this data. In this article, we analyse in detail new challenges in investigating virtual networks. We propose a classification in three categories, which might help to develop new methods and possible solutions to simplify further necessary investigations in virtual network environments. The defined challenges are classified according their potential to impede the investigation. Based on this classification we derive a list of basic conditions, describing different necessary requirements to implement a successful, valid and ongoing network forensic investigation in these virtual networks.

Terabit elastic optical networking (EON) is foreseen as a viable solution to extend the lifetime of a network exploiting the available bandwidth in previously deployed optical fibers. EON is based on bandwidth-variable transponders capable of supporting multiple bit rates and/ or modulation formats according to traffic requirements and node architectures that route arbitrary channel bandwidths. Thus, EON increases the heterogeneity of the network, which may create the need for autonomic adaptive and/or cognitive techniques. In this context, the software-defined networking (SDN) paradigm emerges as an opportunity to enable such techniques thanks to the centralized view of the network by decoupling the control plane and the data plane. This paper surveys different activities carried out at the Optical Technologies Division in Centro de Pesquisa e Desenvolvimento em Telecomunicações, Brazil. We review an optical transport SDN controller for virtual optical networks that supports two adaptive algorithms. First, the autonomic flexible transponder reconfigures the transmission modulation format according to a threshold level. Second, the adaptive global spectrum equalization reconfigures the wavelengths' attenuation profiles applied at the optical nodes to improve the signals' optical signal-to-noise ratio (OSNR) at reception. Finally, we report experimental results of an in-band OSNR monitor for advanced modulation formats.

“…The study conducted in [3] provides a set of requirements that are the basis of the comparison between the controllers: TLS Support, virtualization, open source, interfaces, GUI, RESTful API, productivity, documentation, modularity, platform support, age, OpenFlow support, and OpenStack Neutron support. The comparison was done using a Multi-Criteria Decision Making (MCDM) method named Analytic Hierarchy Process (AHP) adapted by a monotonic interpolation/extrapolation mechanism which maps the values of the properties to a value in a pre-defined scale.…”

The control plane is an essential part of the SDN architecture, so it is very important to give proper attention to any proposal or design of an SDN controller. During the past few years, several controllers have been developed and several studies have been done to evaluate, compare and test the performance of these controllers. In this paper, new controllers are tested, such as ONOS and Libfluid-based controllers (raw, base), using Cbench, an OpenFlow testing tool. Even though the results show that MUL, Beacon, and Maestro (in latency mode) are the best performing controllers; however, the selection of the bestfitted controller should be based on several criteria, per user requirements.
