I. Analysis of the Three-way handshake protocol First, let's look at one of the most common things in our life: During our online shopping, we often chat with customer service like this: We asked Customer Service about something, Customer Service answered, and then we broke the network... After a while, we will log on again and receive a response from the customer service. This interaction process co

For the vast number of operators to operate the site, the most headaches is Baidu update after a night after the keyword ranking suddenly dropped n bit. The author last in the article (Sharing Operation Rainbow Auxiliary network three months of feeling and experience) also anxi these three months of hard "work" has not been wasted, who knows Baidu in last week's update to give me blow, all of a sudden let me get up a keyword ranking in search results

Situation Awareness-Based Network Security Event Prediction Method Analysis Machine Learning is applied in the security field, especially in various attack detection (external intrusion detection and internal threat detection). I believe many people have become accustomed to it. The focus of current machine learning applications is to detect attack threats in the system/organization in a timely manner, thus

Deep neural Network, the problem of pattern recognition, has achieved very good results. But it is a time-consuming process to design a well-performing neural network that requires repeated attempts. This work [1] implements a visual analysis system for deep neural network design, Deepeyes. The system can extract data

Optical Fiber Network Fault Test Equipment Analysis In recent years, as people have higher and higher requirements on the rate of broadband, because the performance of optical fiber is better than that of copper cable, it has been widely used in the backbone construction of broadband projects. At the same time, due to the increasing coverage of optical fibers, fiber failure detection is becoming more and m

Analysis on network packet loss caused by full tracking of ip_conntrack connections When the access volume of our online web server is very large, packet loss occurs during network connection. You can view the log by running the dmesg command and find the following information: kernel:ip_conntrack:tablefull,droppingpacket.kernel:printk:1messagessuppressed.kernel:

Basic knowledge of network requests our network request is using an HTTP requestHTTP request format: Requested method, request header, request bodyRequest fields for the HTTP request fields: The requested header, and some settings for the requested headerHTTP request Response fields: The reply header of the request can be used to understand some of the status information that the server gives us.Project Sou

is only 1-0.3 = 0.7. According to this data, what configuration should I configure for the 100 video capture servers? 1 Nic, which is generally 100 MB in popularity. Check that the actual transmission speed can reach m/s. The pressure is not as high as M network transmission pressure. 2 Disk: The above analysis also shows that the disk consumes a large proportion of time. However, the speed of serv

Of course, we choose the legacy interfaces in Chapter 1 to go to the analysis. Fiber _ Lookup () We mentioned earlier that during fib initialization, The config_ip_multiple_tables macro leads to two methods of Fib table initialization, so there is a situation where multiple route tables exist and no more route tables exist, let's first look at the absence of Multiple Route tables. Static inline int maid (struct net * Net, const struct flowi * handle,

At the same time, the second and third layer of packet re-check. Send data over the Internet. Finally, many nodes are sent to the target host Pc_c.Now we think of a problem, pc-a and Pc-c MAC address if it is the same, will not affect the normal communication it! The answer is not affected, because the two host

There are many things worth learning about the 3G local access network. Here we mainly introduce the load requirements analysis of the 3G local access network. With the rapid development of 3G technology and applications, 3G local access network is facing a huge challenge. In this context, this article discusses the fe

Some people often ask why I can only see my own communication? Why can't I see the Communication Status of XX? Is it software limitations? In fact, this kind of problem is not the limitation of the software, but caused by improper installation and deployment of the software. We know that the network protocol analysis software works in sniffing mode. It must collect raw data packets in the
