[. . . ] A DHCP server can either be a designated PC on the network or another network device, such as a router. DMZ Demilitarized Zone. When a router opens a DMZ port to an internal network device, it opens all the TCP/UDP service ports to this particular device. The feature is used commonly for setting up H. 323 VoIP or Multi-Media servers. DNS A program that translates URLs to IP addresses by accessing a database maintained on a collection of Internet servers. Domain Name The unique name that identifies an Internet site. Domain Names always have 2 or more parts, separated by dots. In www. airlive. com, the "airlive. com" is the doman name. 19 X. USB User's Manual 5. Wireless Network Glossary DoS Attack Denial of Service. A type of network attack that floods the network with useless traffic. Many DoS attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the TCP/IP protocols. Encryption Encoding data to prevent it from being read by unauthorized people. The common wireless encryption schemes are WEP, WPA, and WPA2. ESSID (SSID) The identification name of an 802. 11 wireless network. Since wireless network has no physical boundary liked wired Ethernet network, wireless LAN needs an identifier to distinguish one network from the other. Wireless clients must know the SSID in order to associate with a WLAN network. Hide SSID feature disable SSID broadcast, so users must know the correct SSID in order to join a wireless network. Firewall A system that secures a network and prevents access by unauthorized users. Firewalls can be software, router, or gateway. Firewalls can prevent unrestricted access into a network, as well as restricting data from flowing out of a network. Firmware The program that runs inside embedded device such as router or AP. Many network devices are firmware upgradeable through web interface or utility program. FTP File Transfer Protocol. A standard protocol for sending files between computers over a TCP/IP network and the Internet. X. USB User's Manual 20 5. Wireless Network Glossary Fragment Threshold Frame Size larger than this will be divided into smaller fragment. If there are interferences in your area, lower this value can improve the performance. If there are not, keep this parameter at higher value. You can try 1500, 1000, or 500 when there are interference around your network. Full Duplex The ability of a networking device to receive and transmit data simultaneously. In wireless environment, this is usually done with 2 or more radios doing load balancing. Gateway In the global Internet network, the gateways are core routers that connect networks in different IP subnet together. In a LAN environment with an IP sharing router, the gateway is the router. [. . . ] The used of channel binding might be prohibited in EU countries. TX Output Power Transmit Output Power. The TX output power means the transmission output power of the radio. Normally, the TX output power level limit for 2. 4GHz 11g/b is 20dBm at the antenna end. The output power limit for 5GHz 802. 11a is 30dBm at the antenna end. UDP (User Datagram Protocol) A layer-4 network protocol for transmitting data which does not require acknowledgement from the recipient of the data. Upgrade To replace existing software or firmware with a newer version. X. USB User's Manual 28 5. [. . . ]
