changed to the length field, because the raw 802.3 frame used at that time only needs to support the Ipx/spx type of protocol. Two years later, the officially released IEEE802.3 joined the LLC header, leading to a non-compliant standard with the IEEE official standards. In order to be compatible with the new IEEE Standard, the Raw 802.3 data field is specified as the first two bytes of the raw field and th

WEP (Wired Equivalent encryption) Although the name seems to be a security option for wired networks, this is not the case. The WEP standard has been created in the early stages of wireless networks and is designed to become a necessary security protection layer for WLAN in Wireless LAN. However, the performance of WEP is undoubtedly disappointing. It is rooted in design defects.In WEP systems, data transmitted over wireless networks is encrypted using a random key. However, the method WEP uses

At present, the application of WLAN has become an important means of high speed wireless data access in indoor community, especially in hot area. Many readers still have a smattering of wireless routing settings. This time we specially take a wireless router as an example, detailed introduction how to set up the router. Wireless routers in the market a wide variety of, but million change in which, as long as the reader extrapolate, no line by the setting nature can be easily. For broadband wi

Configuration and application of Radius Authentication Server (802.1x) Author: Beijing Normal University Zhuhai branch-School of Information Technology-Jiangnan Environment: Windows 2003 Radius server + Cisco 2950 switch + Windows XP/2003 Client IEEE 802.1x protocol IEEE 802.1x is a port-based network access control protocol. The Authentication architecture of this protocol uses the logical functions of "co

Overview: Media independent interface (media-independent interface), or media-independent interface, is the Ethernet industry standard defined by the IEEE-802.3. It includes a data interface and a management interface between MAC and PHY. Data interfaces include two independent channels used for the transmitter and receiver respectively. Each channel has its own data, clock, and control signal. The MII data interface requires a total of 16 signals. Th

address is defined by the Institute of Electrical and Electronic Engineers (IEEE). Assign an EUI-64 address to a network adapter, or derive it from an IEEE802 address. During the IPV6 stateless address autoconfiguration process and the link-local link-local address generated under the interface, the interface ID section is typically generated according to EUI-64 rules: that is, the next 64-bit portion of the IPV6 address 128-bit length.

~ 1500 bytes. · FCS-this field contains a 32-bit Cyclic Redundancy Check (Cyclic Redundancy Check, CRC) value to verify damaged frames. The initial Ethernet II frame format has some drawbacks. To allow conflict detection, 10 Mbits/s Ethernet requires the minimum group size to 64 bytes. This means that if the frame length does not reach the standard, 0 must be used to fill the short frame. Therefore, the upper-layer protocol must contain a "length" field to distinguish the actual data from the

Poe refers to the transmission of data signals to a Poe based on IP terminals (such as IP telephones, wireless LAN access point APS, network cameras, etc.) while the existing Ethernet CAT.5 cabling infrastructure is not changed Ethernet It can also provide DC-powered technology for such equipment. Poe is also known as a LAN based power supply (PoL) or active Ethernet, sometimes referred to as Ethernet power, which is the latest standard specification for transmitting data and power while using e

. The official site of OSDL is http://www.osdl.org /. POSIX Unix was born in the ATT Bell Laboratory in 1969, and was rewritten using the C language in 1973. Since then, Unix has good portability. However, when ATT was able to enter the computer market in 1984 due to its split, it triggered a war in the Unix industry. At that time, the two most important versions were ATT's System V and Berkeley's BSD. There are many differences between the two in terms of technology (such as terminals) and cu

In the past, we have always emphasized route settings. Therefore, for wireless networks, route settings are more important, which directly affects the signal strength. So how can we make a good routing configuration? Next, let's take a look at how the master's wireless route connection settings are implemented. Efficient users must set up wireless route connections. The following is a collection of methods for setting wireless route connections. It is a common method for fans. Take the opportuni
