I have read in the next
that :
OpenFLow switch is able to keep track of the sequence number of each traffic flow to detect MAC spoofing attack. Upon reception of a frame, the algorithm calculates the gap G between the sequence number of the current frame and that of the last frame received from the same source address. If G = 0, the current frame is considered as a re-transmitted frame, while if G = 1 or G = 2, the current frame is considered the right one. But, if the gap between the current frame and previous frame is in between 3 and 4096, then it is considered an abnormal sequence number.
In my case, I use Ryu Controller and I would like to do the same work, where the switch sends the alert to the controller after the switch detects the gap.

Answer
I have experience with software defined radio where one can implement the digital down and conversion using programmable devices mostly field programmable gate arrays. One can also software implement the base band processing functions using programmable devices such as FPGA and digital signal processing DSPs.
Similarly one can implement network functions using similar techniques where one can represent the functions in a software code that can be implemented on programmable devices.
In fact any digital processing functions can be implemented on programmable platforms such as DSPs and FPGAs.
For specific applications you can search the web.
As a matter of definition software defined device= digital programmable platform + software deification of the function to be implemented. The platforms are in form of programmable DSP and FPGA kits.

Answer
In my opinion, it depends on many factors, i.e. it depends on several factors such as: what you want to prove/implement with your research, what is your previous knowledge of SDN controllers, etc.
For example, I have worked with NOX, POX, Ryu, Floodlight, OpenDaylight and ONOS, and my experience is that Ryu and ONOS are currently the best ones. I usually leverage Ryu for fast prototyping/proof-of-concepts, while I use ONOS when I'm implementing a next-step of the previous prototype (something that could be standardized/used by industry, etc.). In particular, in you haven't even worked with an SDN controller, I'd start with Ryu.

I am working with SDN to manage flows in a network. I wanted to experiment/know if there is a way I can simulate different radios(Bluetooth,Wifi,Zigbee) which work in the same ISM band to better manage the whole environment. Any help is appreciated. Also best wishes for the new year
Relevant answer
Dear Kaustubh,
I think the best way to manage the wireless communication in the ISM band is to use the techniques of the cognitive radio systems. So one has a radio which can sense communicate with control center and get a decision and a connection information from the center. There is the compressive sensing techniques to reduce the sensing signal load.
You can find many many papers when you make a literature survey.

I am using mininet and i want to monitor the flows which enter in the controller and FEs to see the performance metrics like Bw, delay, and etc.
please suggest monitoring tools to monitor the SDN network (controller and FEs).
Thanks a lot

You're welcome! I'm sure you can still refer to the link I provided above for Ryu, which is a python based controller. I have no experience with floodlight so I sadly cannot help there.
As per having a real time module, you can run wireshark on the controller attached to a switch, to which you can pass the traffic from hosts to and from.

Hi,
I want to connect an optical network simulated in OMNET++ to an SDN controller of MININET and also wants to control my network with that controller. Can anyone suggest me how can I connect these?
Thank you in advance.
Relevant answer
Answer
Hi Srija, to the best of my knowledge, OMNeT++ is a simulator and Mininet is an emulator (I've used both), so I don't think connecting Mininet with OMNeT++ is feasible.
I believe the best option would be implementing a controller in OMNeT++ (probably you will be able to find some implementations online already), but please note it will be a simulated controller (i.e. modelled). If that's ok for you, then go ahead. But if you need to use a real controller for some reason, then you'll probably need Mininet and you'll probably have to migrate your work in OMNeT++ to the switches in Mininet (either OVS, ofsoftswitch, etc.).
I hope this helps!

We have Aruba switches , in virtualbox one vm running with SDN controller and another vm running minnet topology we need to connect mininet switches with physical switch to make a topology. Anybody help us to configur, adapter setting and bridge configuration in detail.
Thanks in advance.
Relevant answer
Answer
You need to add the physical interface of the switch, e.g. "eth0, eth1" as a port to the OpenvSwitch bridge. The link below shows commands you can utilize to achieve the connection
If you are using VMWare, VBox, etc, another methods is using "tuntap" commands, as shown in tutorial below

Let me know about SDN best communities for beginners and professional.
which controller enable future integration to other technologies support ?
Relevant answer
Answer
Muhammad Awais i am working on SDN and i read alot of documentation regarding SDN. Trema and Floodlight are oldest one. With respect to documentation, Floodlight is the best one. OpenDayLight is newer as compare to Floodlight and Trema but its opensource community is very strong and is emerging rapidly. Some like to work on Ryu controller.but my chice would be OpenDayLight controller. It has both documentation for beginners as well as senior developers. All the controller provide you the option of integration. it again depend on your use use. you can use third party software and APIs will help you regrading integration.

If i training Machine learning algorithm using well know dataset like NSL-KDD and then I create a detection module, how to use it to detect abnormal in SDN environment and which feature I need to collect from SDN-Controller for ML module.
Thanks
Relevant answer
Answer
One need to collect the flow statistics from the OpenFLow switch. Then extract features like entropy of destination address, flow duration, number of packets in a flow etc. In that features trained the model. Keep this model inside the controller. If some one good in Python, can use POX controller, but sometimes it not performs well in this respect. Otherwise try for Floodlight.

i have a mathematical model for SDN placement problem and i have to code a program that he can find the optimal number of sdn controller in sdn network ,this program is a approch method
Relevant answer
Answer
to code a program with a aproch method that he can find the optimal number of sdn controller in SDN network in c are we examine how well SOL’s results match original solutions, which are optimal (by definition). In all cases except ElasticTree, SOL finds the optimal solution. Due to complexity of ElasticTree’s optimization, SOL suffers a 10% optimality gap: the relative error in the objective value computed by SOL (i.e., relative to the true optimal objective value).

Check my book chapter that I have written for Smart Learning Environment in a Private cloud.
The SDN approach is different here as the hypervisors, cloud activators, orchestrators need to support your backend systems...
Almost we could not call our servers as SDN, but most of the learning softwares runs under Private cloud follows 20% of SDN methodology....

Software-defined networking (SDN) and network function virtualization (NFV) are hot topics. They are clearly related, but how are they different? How do they complement each other in the 5G era?
Relevant answer
Answer
Dear Zhan Wang,
in general, SDN (Software Defined Networking) can be seen as a framework for setting up flexible, on-demand, quasi-programmable network services. Bild expresses this and makes clear that the basic, logical architecture of SDN is similar to the general logical architecture of a physical server.
The three functional layers within the logical architecture of SDN-based Network Infrastructure are:
  • Network Device Plane: This plane represents the networking of SDN-enabled devices.
  • Control Plane: This plane contains SDN controllers. These translate the statements generated by the SDN application (policies, policies) into messages sent to the SDN-enabled devices. SDN-enabled devices can be uniformly controlled across through a standard, so-called Southbound API
  • Application Plane: Included in this plane are various software tools called SDN Applications (S-App) for setting up network services. The SDN applications are used to create instructions for controlling the SDN-enabled devices. The so-called Nordbound API, as an open software interface, should enable any configuration of the network services according to the current requirements in a uniform manner.
Any Network Function that does not necessarily have to be implemented in hardware and provided in the form of a hardware component can be software-implemented - e.g. on the basis of VMs - realized, de facto virtualized. The network functions realized in this way are called VNFs (Virtualized Network Function). Network Services based on VFNs are referred to as Network Functions Virtualization (NFV). The concepts for NFV are presented in several documents by ETSI. See for example:
ETSI GS NFV 002 – V1.1.1; 2013-10: Network Functions Virtualisation (NFV); Architectural Framework; Figures 3 and 4!!!
The goals and concepts for SDN and NFV are largely related and similar. My picture should confirm this.

Hello,
Please, I would like to emulate an SDN based heteregenous RAN composed of LTE nodes as well as WIFI Aps.
I know that MininetWifi is a good emulator but for SDN WIFI APs. However, it would not give accurate results if the specification of access point are changed to behave as Lte eNodeB.
Based on the work cited below, OpenNet does not provide high-level abstraction APIs for wireless links nor emulation of wireless nodes (e.g., access points and stations are not equipped with wireless network interfaces), and neither mechanisms to select new access points before disconnection of current link to further shorten handover latency.
Please, any recommendation or suggestion on which emulator to use to support both RATs (Wifi/LTE)

Is there any way I could send the network data from data layer to SDN controller .I have looked into Cisco's net-flow ,but not sure it supports open source SDN controllers
Relevant answer
Answer
Yes, easily with OpenFlow. Just match the traffic belonging to the flows of interest and forward them to the logical CONTROLLER port. The packets will be received encapsulated as OpenFlow packet-in messages at the controller.
Exemplary add-flow matching on the L2 source MAC and sending to Controller using Open vSwitch:
ovs-ofctl add-flow br0 \ "table=0, dl_src=01:00:00:00:00:00/01:00:00:00:00:00, actions=CONTROLLER"
