IEEE and 10GEA (Gigabit Ethernet Alliance) are the two most important organizations in Gigabit Ethernet standardization.Gigabit Ethernet standards and specifications are many, in the standard, the first 2002 years of IEEE 802.3ae, and then continue to have a new Gigabit Ethernet specification, such as the 2006 IEEE 802
If you are not a child of the School of network engineering, you have a blank understanding of network. I have heard of TCP/IP before. Seriously, it seems a headache, but the protocol is dead. I am familiar with it after reading it several times.
Read the book and learn about the TCP/IP concepts. Otherwise, the subsequent work will not proceed.
The TCP/IP protocol is divided into four layers.

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
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

◎ 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

THGs is a powerful network performance analyzer that can be accessed locally or remotely controlled by Surveyor software for effective diagnosis, fault identification and monitoring of any full or half duplex 10 M/100 M/M Ethernet network provides necessary tools.

Absrtact: Spanning tree algorithms and protocols are the basis for automatically generating network topologies. This paper expounds the content of spanning tree algorithm and protocol, and gives the realization process in Ethernet switch. It is proved by practice that the square tip has a good effect on the analytic optimal topological structure of the network.

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

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
