Hii,

When I ping one host with another host, it generates an error "destination host unreachable" (i have manually giving IP address range 10.0.0..1 to 10.0.0.12 ).

eth0 - 192.18.56.102 DHCP server - 192.168.56.100

eth1 - 10.0.2.15 l0 (loopback) - 127.0.0.1

When I ping 192.168.56.1 then it successfully pings.

But when I have used miniedit to draw a network and tried to connect them between two hosts on the same or different switches, it shows the following error "destination host unreachable problem.

Kindly help.

hi

i want to know how SDN can Improve network performance like delay, throughput, pdr

for the delay i understand that SDN controller have a global view of network and so i chose the best bath (less congestion)

what about the throughput ?

and Packet Delivery Ratio

thanks

is there an ability to connect the simu5G with open-flow on omnet++ ?

to be able to create a 5G network controlled by the SDN controller

im trying to find the best simulator for 5G SDN networks

im trying to work with omnet++ but i find its kinda difficult, is there any tutorial of something i can learn from

dose the NS-3 also difficult ?

any suggestion for a simple powerful simulator ?

What should I do if I want to simulate my design of packet transmission mechanism in the vehicle networking security on NS-3? P.S. I'm still new in the car networking and computer networks, so I hope you give me as much detail as possible, and I'll appreciate it!

Recently I am looking for SDN issues, but still no idea which issues should focus.

We are working on the linear topology of multiple APs, but the connection between stations in different APs cannot be verified unless we add an SDN controller to the network! Is there any method to make this connection possible? because we want to compare the network in two cases: with and without a controller.

Hello everyone. I'll start working on my master thesis and my task will be to simulate a SDN architecture with some IoT devices in a 5G environment. I've read that Simu5g (http://simu5g.org/) should be a viable option; I would like to know if anyone here faced some similar challenges. I found this article ( ) but it seems quite outdated, so I'm asking here. Thanks.

I am searching a research problem related attack/anomaly detections in SDN using deep learning methods. can I get some idea?

Mininet is a simulator to create virtual networks and SDN has dual role in DDOS attack. it can prevent a  DDOS attack or became a tool to carry out DDOS

Dear,

I need your help, please.

Could someone have an idea on an open-source simulator for SDN (Mininet) and Blockchain (Ethereum)?

Thanks.

I want to implement SDN in NS3. Please help me or suggest me some tutorials

hey, I want to develop energy efficient SDN and to integrate with Edge computing based IoT applications. So, which emulator/simulator would you recommend for integration SDN, Edge computing and IoT devices. Please suggest best open source Emulator / Simulator.

how load is measured in SDN control plane and how we know controller is overloaded because everything in SDN is programmable, so how can we say overloaded.

We would like to implement SDN based IoT secure application. Please suggest best open source Emulator / Simulator.

SDN sends the specified traffic data.

For example, it first classifies the traffic and then sends the specified traffic (such as a download or video stream).

I downloaded the Mininet VM and I have two windows 7 vms. I want to create an SDN lab that will use the two windows 7 vms as hosts in Mininet. Please how can I go about that?

Hi,

I need to simulate DDoS attack and mitigate it using SDN, can any one please suggest a simulation and controller to do the task.

looking forward to hear your ideas

kind regards

the detection is related to the DDoS attacks. Need to find or guidance regarding some open source project that has done machine learning in java and used the SDN network.

I would like to know how to send sensor/IoT data using SDN network? Say suppose I have some csv files containing temperature data then how do I send those csv files using SDN?

Hello, I am an Undergraduate Final Year Student, I would be so glad if someone gives me a guideline for recent SDN thesis topic which would be suitable for Undergraduate Student.

Hi,

I am trying to compute the communication cost of the SDN network. For that load of the switches will be multiplied with the link cost. But I am not finding the cost in USD to send packets from switch to controller.

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.

Dear Colleagues

I hope you are well and safe.

I am doing my master thesis on SDN, My supervisor wants me to do a Security solution or some QoS monitoring like Dynamic path selection...etc

I'd really appreciate some suggestions for a new idea or some security-related solutions, so I can narrow my targeting.

I sincerely thank you in advance for your help.

Kindest regards.

I want to extract Hop count, link utilization and random placement from Topology zoo data set, and I have no idea how to do that. additionally, i'm going to use that criteria for SDN controller placement problems in matlab.

I am doing research on the topic "Implementing Fast Routing in SDN". I need help to get related research papers so I can continue my research work efficiently.

Software-Defined Networking (SDN) is a promising paradigm that serves as a pillar in the

the fifth generation of mobile systems (5G) that could help to detect and mitigate cyber-attacks.

I would like to connect 2 Ryu controllers (C1,C2) to one switch with two different table-miss. When a certain match takes place the switch sends to C1, and for different match, the switch sends to another controller.

When I run 2 controllers, the switch has only one entry as follow :

cookie=0x0, duration=30.805s, table=0, n_packets=538, n_bytes=37602, priority=0 actions=CONTROLLER:65535.

is there any way to add 2 defferent entries for two different controller , for instance:

cookie=0x0, duration=12s, table=0, n_packets=2, n_bytes=500, priority=10 actions=CONTROLLER:66556 +++++++++++ cookie=0x0, duration=18.371s, table=0, n_packets=87, n_bytes=7500, priority=0 actions

How do I use a data set to evaluate an intrusion detection system in a software defined intrusion detection system?

Hello everybody,

I'm trying to guess how to implement the python script of the machine learning model in the Ryu SDN controller python script should I just save the model and load it in the script ?

Also if there is any help to give me ideas how to implement a python script in the controller so it can detect Botnet I guess I have an idea like requesting flows from the switch every each 5 seconds for example and then predict if the attack is occurring or not so any help (code, documents, tutorials....etc) will be appreciated

Finaly, I want to ask if scapy is a good tool to generate normal traffic and botnet (master and slaves) traffic

Hope you help me

Hii All, is there any simulation tool available to calculate power consumption of SDN switches and controllers. Using mininet and floodlight controller i have successfully tested the performance of a sdn topology. Now i want to reduce the power consumption by each device. Is it possible through mininet or any other tool i need? If i can acheive it through mininet, then provide me the procedure.

Its really urgent for me. Please help me. many many thanks.

Please provide me any links if so with the proper justification

Dear Experts

I have a university project to build a soft load balancer in SDN/OpenFlow (Linux) environment. I'm thinking to use mininet as OpenFlow network simulation. Can you help me to find if and how we can accomplish the below requirements with mininet or should I consider some other simulator?

1. Customized topology with "4 servers and 48 client nodes" "The interface shall contain classification of client nodes having different requirements of bandwidth at different times. This shall be 4 periods with different bandwidth distribution."

2. Which OpenFlow controller can fulfill these requirements? "Measure Performance and Utilization Statistics" a. Throughput b. Delay c. Utilization d. Load Distribution e. Response time

This project requires designing a network load balancer with OpenFlow that will provide GUI based interface to the network administrators. The data from the GUI will be fed to the load balancing controller that will coordinate with network nodes to manage the routes to the server.

Please answer whichever part of the question you can guide me for.

Thanks in advance.

Please suggest me some link that might help to write python code that can measure the delay of a specific path (the path that I am interested) using pox as a controller. Though I have found opennetmon in https://github.com/TUDelftNAS/SDN-OpenNetMon and tried with this one and its not working. So I need some alternative way that might help me.

Thank you
