Appendix D: Glossary

802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input multiple-output). MIMO uses multiple transmitter and receiver antennas to allow for increased data throughput via spatial multiplexing and increased range by exploiting the spatial diversity, perhaps through coding schemes like Alamouti coding. The Enhanced Wireless Consortium (EWC) [3] was formed to help accelerate the IEEE 802.11n development process and promote a technology specification for interoperability of next-generation wireless local area networking (WLAN) products. 802.11b - The 802.11b standard specifies a wireless networking at 11 Mbps using direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to as Wi-Fi networks. 802.11g - specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS) technology, using OFDM modulation and operating in the unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE 802.11b devices, and WEP encryption for security. Access Point - A device that allows wireless-equipped computers and other devices to communicate with a wired network. Also used to expand the range of a wireless network. Ad-hoc Network - An ad-hoc network is a group of computers, each with a wireless adapter, connected as an independent IEEE 802.11 wireless LAN. Ad-hoc wireless computers operate on a peer-to-peer basis, communicating directly with each other without the use of an access point. Ad-hoc mode is also referred to as an Independent Basic Service Set (IBSS) or as peer-to-peer mode, and is useful at a departmental scale or SOHO operation. AES (Advanced Encryption Standard) - A security method that uses symmetric 128-bit block data encryption. ACS (Auto-Configuration Server) - Through ACS (Auto-Configuration Server) you can perform auto-configuration, provision, collection, and diagnostics to the device. ATM (Asynchronous Transfer Mode) - ATM is a cell based transfer mode that requires variable length user information to be segmented and reassembled to/from short, fixed length cells. It uses two different methods for carrying connectionless network interconnect traffic, routed and bridged Protocol Data Units (PDUs), over an ATM network. Bridging - A device that connects different networks. Browser - An application program that provides a way to look at and interact with all the information on the World Wide Web. DDNS (Dynamic Domain Name System) - Allows the hosting of a website, FTP server, or e-mail server with a fixed domain name (e.g., www.xyz.com) and a dynamic IP address. Default Gateway - A device that forwards Internet traffic from your local area network. DHCP - A networking protocol that allows administrators to assign temporary IP addresses to network computers by leasing an IP address to a user for a limited amount of time, instead of assigning permanent IP addresses. DMZ (Demilitarized Zone) - Removes the Router's firewall protection from one PC, allowing it to be seen from the Internet. 84

Figure 4-15 Obtain an IP address automatically: Select this option, the Router will be able to obtain IP network information dynamically from a DHCP server provided by your ISP. Note: 1) The response message from a DHCP server typically contains a number of configuration parameters (DHCP options) for the Router. The DHCP options include IP network information, and also the vendor-specific options. In some cases, the Router is implemented to perform user-defined operations (as shown below). You can implement your own treatment of all such options. If the Router is functioning as a DHCP client, it must identify itself in option 61 (client-identifier) in every DHCP message. DUID/IAID is portion of option 61. Option 60 Vendor ID: The option code 60 used to identify Vendor class. Option 61 IAID: IAID (Identity Association ID) assigns an Identity Association ID to individual interfaces. In cases where the device is functioning with a single DHCP client identity, it must use value 1 for IAID for all DHCP interactions. In cases where the device is
TD-W8970N Wireless N ADSL2+ Modem Router User Guide functioning with multiple DHCP client identities, the values of IAID have to start at 1 for the first identity and be incremented for each subsequent identity. For example, the device may use IAID value 1 for the first physical interface and value 2 for the second. Alternatively, the device may use IAID value 1 for the virtual circuit corresponding to the first connection object in the data model and value 2 for the second connection object in the data model. Option 61 DUID: Specifies the name of the interface whose link-layer address the server is to use as its DUID (DHCP Unique Identifier). You must enter a value for this parameter or the server will not start. When the server starts, the DUID is written to the system log. Option 125: The option 125 allows DHCP server to be pre-configured with policy for handling classes of devices in a certain way without requiring DHCP server to be able to parse the unique format used in client-identifier option. Use the following IP Address: If you are provided with a static IP/gateway Address, please select this option, and then enter the WAN IP Address, WAN Subnet Mask and WAN gateway IP Address manually. 5. You will see the next screen as below. You can enable the NAT, SPI Firewall, and IGMP Multicast, if you are not sure about the settings, just leave the default settings. Click Next.

TD-W8970N Wireless N ADSL2+ Modem Router User Guide DDNS (Dynamic Domain Name System) - Allows the hosting of a website, FTP server, or e-mail server with a fixed domain name (e.g., www.xyz.com) and a dynamic IP address. Default Gateway - A device that forwards Internet traffic from your local area network. DHCP - A networking protocol that allows administrators to assign temporary IP addresses to network computers by leasing an IP address to a user for a limited amount of time, instead of assigning permanent IP addresses. DMZ (Demilitarized Zone) - Removes the Router's firewall protection from one PC, allowing it to be seen from the Internet. DNS (Domain Name Server) - The IP address of your ISP's server, which translates the names of websites into IP addresses. Domain - A specific name for a network of computers. DSL (Digital Subscriber Line) - An always-on broadband connection over traditional phone lines. Dynamic IP Address - A temporary IP address assigned by a DHCP server. EAP (Extensible Authentication Protocol) - A general authentication protocol used to control network access. Many specific authentication methods work within this framework. Encryption - Encoding data transmitted in a network. Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Firewall - A set of related programs located at a network gateway server that protects the resources of a network from users from other networks. Gateway - A device that interconnects networks with different, incompatible communications protocols. IEEE 802.11b - The IEEE 802.11b standard specifies a wireless networking at 11 Mbps using direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz, and WEP encryption for security. IEEE 802.11b networks are also referred to as Wi-Fi networks. IEEE 802.11g - Specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS) technology, using OFDM modulation and operating in the unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE 8021b devices, and WEP encryption for security. Infrastructure Network - An infrastructure network is a group of computers or other devices, each with a wireless adapter, connected as an IEEE 802.11 wireless LAN. In infrastructure mode, the wireless devices communicate with each other and to a wired network by first going through an access point. An infrastructure wireless network connected to a wired network is referred to as a Basic Service Set (BSS). A set of two or more BSS in a single network is referred to as an Extended Service Set (ESS). Infrastructure mode is useful at a corporation scale, or when it is necessary to connect the wired and wireless networks. IP Address - The address used to identify a computer or device on a network. IPoA (IP and ARP over ATM) - A protocol that provides extensions to the IP Group for handling IP over ATM flows. ISP (Internet Service Provider) - A company that provides access to the Internet.

TD-W8970N Wireless N ADSL2+ Modem Router User Guide LAN - The computers and networking products that make up your local network. MAC (Media Access Control) Address - The unique address that a manufacturer assigns to each networking device. NAT (Network Address Translation) - NAT technology translates IP addresses of a local area network to a different IP address for the Internet. MER (MAC Encapsulation Routing) - MER allows IP packet to be carried as bridged frames. There are many applications, such as IPoA, DSL networks and other frame-based network. Depending on your equipment, they can be either bridged or routed within the network. Network - A series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users. Ping (Packet Internet Groper) - An Internet utility used to determine whether a particular IP address is online. Port - The connection point on a computer or networking device used for plugging in cables or adapters. PPPoE (Point to Point Protocol over Ethernet) - PPPoE stands for Point to Point protocol over Ethernet, this protocol is used as a type of broadband connection that provides authentication (username and password) in addition to data transport. PPPoA (Point to Point Protocol over ATM) - PPPoA stands for Point to Point protocol over ATM, this protocol is also used as a type of broadband connection that provides authentication (username and password) in addition to data transport. RADIUS (Remote Authentication Dial-In User Service) - A protocol that uses an authentication server to control network access. RJ45 (Registered Jack-45) - An Ethernet connector that holds up to eight wires. Router - A networking device that connects multiple networks together. RPC (Remote Procedure Calls) - RPC is a powerful technique for constructing distributed, client-server based applications. It is based on extending the notion of convention, or local procedure calling, so that the called procedure need not exist in the same address space as the calling procedure. The two processes may be on the same system, or they may be on different systems with a network connecting them. By using RPC, programmers of distributed applications avoid the details of the interface with the network. The transport independence of RPC isolates the application from the physical and logical elements of the data communications mechanism and allows the application to use a variety of transports. Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services. SOHO (Small Office/Home Office) - Market segment of professionals who work at home or in small offices. SSID - A Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless local area network. For the wireless devices in a network to communicate with each other, all devices must be configured with the same SSID. This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless Access Point and to the wireless network name. Static IP Address - A fixed address assigned to a computer or device that is connected to a network.
