From the application requirements, the wireless network is very suitable for schools of some sites that are not easy to network wiring applications. Now most of the campus has wired LAN, how to further expand the original network, so that every corner of the campus in the network, the formation of a true sense of the campus network? This article is to introduce how to use Wireless LAN technology to form a campus network. Wireless network Infrastructure Wireless LAN (Wireless local area network

1. Work Summary Recently, the IEEE is working on a new project the project is to develop a standard for the operation of Gigabit Ethernet (10GbE) transmission based on the current copper structured cabling system, which is collaborating with leading experts from integrated wiring, electrical, test equipment and system design, Panduit belong to one of the leading ranks, we have foreseen that with the future increase in transmission rate, cable and conn

that the data rate is higher, the security is better and the quality of service is more and more guaranteed. And from the wireless LAN standards of the supporters and the geographical scope of use, wireless LAN can be said to have three camps: IEEE 802.11 series of standards, European hiperlan1/hiperlan2 and Japan's MMAC series standards. 802.11 series Standard In the 802.11 series, there are 4 standards involving the physical layer: 802.11, 802.1

still pinged the gateway of the VLAN 172.25.6.210 on 6509 using a PC Connected to annett, the problem occurs. When ping with a packet, there is basically no latency, but packet loss occurs when ping with a large packet (close to 18024b, the maximum packet supported by Cisco). The problem must be found here. (5) re-check the configurations of annett, 6509, and NAT servers. We found a problem: Configure VLAN6 and VLAN7 on annett, and add the corresponding ports to VLAN: add VLAN 6 ports = 23 fram

and receiving, and provides standard interfaces to data link layer devices. The Physical Layer Chip is called PHY. The data link layer provides addressing mechanisms, data frame construction, data error check, transfer control, and standard data interfaces to the network layer. The data link layer chip in the ethernet card is called the MAC controller. Many NICs work together. The relationship between them is that the PCI bus is connected to the MAC bus, the MAC is connected to the PHY, And the

) Figure 5 Figure 5 (c) shows the result of five iterations of bilateral filtering of the "image in Figure 5 (a). While a single iteration produces a much cleaner image (Figure 5 (b)) than the original, and are probably sufficient for MO St Image processing needs, multiple iterations have the effect of flattening the colors in a image considerably, but with Out blurring edges. The resulting image has a much smaller-color map, and the effects of bilateral filtering-are to-when easier On a print

SIFS Short interframe Space (SIFS): SIFS is a fixed value in the 802.11 series WLAN, SIFS is the smallest inter-frame interval, so nodes with SIFS have the highest priority to access the wireless link. It is equal to the time it takes for the node to switch from the sending State to the receiving State and to decode it correctly, or the time it takes to transition from the receive State to the sending State, the packets that may be sent after the sifs expires include ACK, CTS frames, and the si

The earliest end-to-end virtualization feature was an Ethernet NIC and an Ethernet switch that supported the IEEE 802.1BR/Qbh standard. In this system, each Nic not only provides multiple virtual NICs, but also identifies each virtual Nic on the switch port by marking the VN-Tag of the Ethernet frame, additionally, you can flexibly divide the

. ============================================Wi-Fi-FiWirelessFidelity, similar to Bluetooth, is a short-distance wireless technology used in offices and homes. This technology uses a 2-4 GHz band, which is currently not licensed as a wireless band. Currently, two standards are available: IEEE802.11a and IEEE802.11b. This technology has its own advantages, so it is favored by manufacturers. WI-FI is a non-profit organization held by a few American information companies with strong interest lever
