Appendix B Glossary Glossary SMTP (Simple Mail Transfer Protocol) SSH (Secure Shell Protocol) S SSID SNMP (Simple Network Management Protocol) TCP (Transfer Control Protocol) TCP/IP (Transmission Control Protocol/ Internet T Protocol) TDMA (Time Division Multiple Access) UDP (User Datagram Protocol) U UPnP (Universal Plug and Play) VLAN (Virtual Local Area Network) V VPN (Virtual Private Network) Description SMTP is an Internet standard for electronic mail (e-mail) transmission SSH is a network protocol that allows data to be exchanged using a secure channel between two networked devices. 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. SNMP provides a management frame to monitor and maintain the network devices. With SNMP function enabled, network administrators can easily monitor the network performance, detect the malfunctions and configure the network devices. Connection-oriented transport layer protocol that provides reliable full-duplex data transmission. Common name for the suite of protocols to support the construction of worldwide Internet works. TCP and IP are the two best-known protocols in the suite. TDMA (Time Division Multiple Access) cuts each wireless data frame into certain number of time slots according to the client connections priority, greatly boosting efficiency of the wireless channel. UDP is a simple protocol that exchanges datagram without acknowledgments or guaranteed delivery, requiring that error processing and retransmission be handled by other protocols. UPnP is a set of networking protocols for primarily residential networks without enterprise class devices that permits networked devices. Group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, they are extremely flexible. Enables IP traffic to travel securely over a public TCP/IP network by encrypting all traffic from one network to another. - 91 -
