Hi All...
Kindly help I want to know how wormhole attack in OPNET.I shall be very grateful to you.
The Internet of Vehicle IoV sensors generate very large amount of data that transmitted via Wireless WAN Networks and processed by cloud servers. The Quality of Service of very large volume of data sent to Cloud Servers, is often constrained by traffic congestions and delays.
What are the latest and more comprehensive survey surveys in the field of DDoS detection and mitigation in software-defined network security in 2023-2024? I only focus on the research results of 2023-2024, rather than the previous year. At present, the quality of the papers I have found is very average, and it is difficult to meet the requirements of new trend research. I hope to find papers that meet the above conditions, and I am constantly investigating
Question1: In Software-Defined Networking (SDN), what are the hot research areas in anomaly-based DDoS detection?
Question2: What are the new or prominent DDoS attack types worthy of study, such as low-rate DDoS attacks and flow table overflow attacks?
Question3: Is the flow table overflow attack proposed much later?
Will SDN/NFV improve handover performance and latency?
How can novel network architectures, such as software-defined networking (SDN) and network function virtualization (NFV), contribute to improved handover performance and reduced latency in future wireless communication systems?
Software-defined networking (SDN) represents a promising networking architecture that combines central management and network programmability. SDN separates the control plane from the data plane and moves the network management to a central point, called the controller that can be programmed and used as the brain of the network. Recently, the research community has shown an increased tendency to benefit from the recent advancements in the artificial intelligence (AI) field to provide learning abilities and better decision making in SDN.

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.

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.
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

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.

Thank you

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)
