When processing TCP data, we need to consider a problem of sticking packets. The so-called sticking packet is that the data received this time is not necessarily completely corresponding to the data sent by the other party. the data sent by the other Party may need to be received multiple times before it can be completed. The actual situation should be reviewed. To solve the packet ordering problem, a data analysis protocol must be developed for proce
The routing protocol analyzer is divided into three types: Portable routing protocol analyzer based on notebook + data collection box, handheld integrated routing protocol analyzer, and distributed routing
For large networks, faults may be difficult to handle, so an effective performance and function testing tool is very convenient. In order to adapt to the current wireless network, the new generation of Wi-Fi wireless protocol analyzer brings new vigor to the network test.
The transmission media of WLAN is electromagnetic waves, which are almost ubiquitous and have no obvious boundaries. However, almost all
The routing protocol analyzer is still very important in routing applications, and the technology is gradually improved. The best way to analyze data packets transmitted over the network is largely determined by the device you have at hand. In the early stages of network technology development using the Internet era of HUB or HUB), the answer is simple. You only need to insert the line on a HUB, and everyth
With the development of wireless LAN technology, protocol analyzer technology is not far behind, So how should we install, operate and protect it? Here we will introduce it to you.
The transmission media of WLAN is electromagnetic waves, which are almost ubiquitous and have no obvious boundaries. However, almost all Wi-Fi hardware has certain security vulnerabilities. Some simplified client configurations m
We can use the network protocol analyzer to observe the network protocol analysis. Here we will explain the network analyzer. The best way to analyze data packets transmitted over the network depends largely on the device you have. in the early stages of network technology development using the Internet era of HUB or H
Fluke network's distributed analyzer (OPV-WGA, hereinafter referred to as WGA) analyzes the distributed switching Environment Network with a new method, allowing users to view the entire layer-7 network in the most rapid and simple way as needed. WGA works with the network monitoring Console (NIS-OPV) and Protocol Analysis experts to easily monitor and analyze 10/100/M Ethernet Over the desktop. It can be i
In fact, many cases of communication on Flash are selected.AMF,After all, it is an as internal object-based sequence protocol, with low capacity and high efficiency. But sometimes to call some existing TCP services, and these services do not provide AMF support, then you have to implement a protocol analysis. In fact, as provides many write and read methods for bytearray, which makes our application very co
with the host in the internal network with the IP address as 10.17.2.30 through the UDP 161 port. As a result, only SNMP traffic between the two hosts can pass through the firewall.
How to configure a firewall to achieve remote access
Remote access to the OptiView Protocol Analyzer through a firewall several things to note. The administrator will add one or two configuration statements to the firewall, u
The protocol analyzer is widely used in wired network and becomes a kind of useful testing and maintenance tool. In the area of WLAN, however, the problem is likely to be overlooked.
The transmission medium of WLAN is electromagnetic wave, it is almost everywhere, and there is no obvious boundary. But almost all Wi-Fi hardware has a degree of security vulnerabilities, and some simplified client configurati
◎ Comprehensive layer-7 testing The integrated protocol analyzer fundamentally solves the problem that has plagued network administrators for a long time. It can be tested from the physical layer to the application layer. That is, it starts from the cable test and ends with packet capture and decoding.◎ Integrate almost all network testing tools The network integrated p
Protocol Analyzer is one of the most powerful tools in the network Administrator library. It can save the company a lot of time and money by turning problems that are difficult, time-consuming, annoying to CEOs and even having to restart all machines to be short-lived and easily reflected in weekly status reports.
However, just like any other complex tool, it must be properly used to achieve maximum benefi
