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

trouble. COLT (1): This is the best meeting of computational Learning Theory, hosted by ACM, held annually. Computational learning theory can basically be seen as a cross between theoretical computer science and machine learning, so this will be seen by some as theoretical computer science rather than AI. A friend of mine made a wonderful depiction of it in one sentence: "A small group of mathematicians in a meeting." Because the field of colt is relatively small, the annual meeting is basical

. 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

, which is the necessary security layer for wireless LAN WLANs. Currently, 64-bit WEP encryption and 128-bit WEP encryption are common. WEP security technology is derived from RSA Data encryption technology named RC4, where data transmitted over a wireless network is encrypted using a randomly generated key. But the algorithm that WEP uses to generate these keys is quickly discovered to be predictable, and for intruders, they can easily intercept and crack these keys, making the user's wireless
