popular Dos attack tool. As the name suggests, it is through simulation to control several zombie hosts to perform DDoS attacks. All zombie hosts create a full TCP connection to the target server.
This tool is written in C + + and runs on Linux systems.
These are the main features of Ddosim:
Simulate several zombie attacks
Random IP Address
Tcp-connection-based attack
Application Layer DDoS attack
Valid requests such as HTTP DDoS

This part of data mainly comes from the following databases:

We explain object detection, how Yolo algorithm can help with image classification, and introduce the Open Source neural network framework Darknet.
There are a few different algorithms for object detection and they can be split into two groups:
Algorithms Based on classification-they work in two stages. in the first step, we're selecting from the image interesting regions. then we're classif
target detection is regression, so a CNN that implements regression does not need a complex design process. Yolo does not choose sliding window or extracting proposal way to train the network, but directly selects the whole graph training model. The advantage of this is that you can better distinguish between the target and the background area, in contrast, the FAST-R-CNN with proposal training methods often mistakenly detect the background area as a specific target. Of course, YOLO has sacrifi
features Multi-scale Training: During training, the model input size is changed every few rounds to make the model robust for different size images. Every 10batches, the model randomly selects a new input image size (320,352,... Multiples of 608,32 because the sampling factor under the model is 32). This training rule forces the model to adapt to different input resolutions. The model is faster for small-size input processing, so the YOLOv2 can adjust speed and accuracy as required. At low reso

Subdivisions=8 If the memory is not large enough, the batch is split into subdivisions sub-batch, and the size of each child batch is batch/Subdivisions In the Darknet code, the batch/Subdivisions is named batch. height=416High width of the input image=416width channels of the input image=3number of channels for the input image momentum=0.9

YOLO v2 is based on a new classification model, somewhat similar to Vgg. YOLO V2 uses 3*3 filter, which increases the number of channels after each pooling. YOLO V2 uses the global average pooling, uses the Batch normil
convolutional neural network on a bongard image, it will first learn the corresponding characteristics of different geometries, each of which can be considered a filter. If there is a corresponding feature, the corresponding classifier is activated.
In order to train a feature extraction neural network (NN), I had to create a new dataset and not use the BP image because they were too few and too similar.
Synthesizing Datasets
To train the feature extraction network, I generated a set of rand
(1) speed/accuracy trade-offs for modern convolutional object detectors
Its main consideration is three kinds of detectors (Faster RCNN,R-FCN,SSD) as the meta structure, three kinds of CNN Network (vgg,inception,resnet) as feature extractor, change other parameters such as image resolution, proposals quantity, etc. The tradeoff between accuracy rate and speed of target detection system is studied.

It is an upgraded version of YOLO, which has made some improv
