Weak Network Simulation of Fiddler packet capture and Simulation of fiddler packet capture 1. Click Rules --> Customze Rules 2. Find m_SumulateModem. The first time is the uplink delay time, and the second time is the downlink delay time, in milliseconds. Set the uplink 2 s delay and downlink 3 s delay. 3. Click Rules-> Performance, select Simulate Modem

Network packet error probability and packet error probabilityTcp and udp checksum are weak. Simply put, the sum of all values is reversed. Even errors in order cannot be prevented, and there are not many digits, 16 bits. Isn't there a 1/65536 probability that an error will not be detected?Note that the layer of Ethernet is crc verification, and the two are combin

Introduction The author was fortunate to participate in the overall project design of the third generation mobile communication technology test network of the Ministry of Information Industry and the design work of the Beijing Area Test Network project. 3G test Network adopts WCDMA R99, CDMA2000 1X, TD-SCDMA three kinds of technology construction. When consideri

Network packet Detection Packet Capture (sniffer): refers to the behavior of data collection on the network, which needs to be done through the NIC. Three ways to access: BSD Packet Filter (BPF) SVR4 Datalink Provider Interface (DLPI) Linux Sock_packet interface Libpca

Ext: 1190000008836467This article describes how a data packet is transferred from a NIC to a process in the hands of a Linux system in a single step.If the English is not a problem, it is strongly recommended to read the following two articles in the reference, which is described in more detail.This article discusses only the physical network card of Ethernet, does not involve virtual devices, and takes the

Whether you are a server administrator, a network administrator, or a VMware administrator, you use a protocol analyzer, also known as a data packet analyzer or a "sniffer", as a common tool for analyzing network problems. These software applications can analyze network traffic in real time, allowing you to view packet

Wireshark packet capture analysis-network protocol Wireshark is currently the most popular packet capture tool. It can run in windows, Linux, and Mac OS X operating systems, and provides a friendly graphical interface. Wireshark also provides a powerful data packet capture function. It can capture the

[Network layer] Analysis Network Layer-Internet Control Packet Protocol ICMP (Internet Control Message Protocol) 1) Message format: the ICMP packet is encapsulated into the data part of the IP packet, and the data part of the ICMP packet
