SOCKET
(1) The Berkeley UNIX mechanism for creating a virtual connection between processes.
(2) IBM term for software interfaces that allow two UNIX application programs to talk via TCP/IP protocols.
Spanning-Tree Bridge Protocol (STP)
Spanning-Tree Bridge Protocol (STP) - Part of an IEEE standard. A mechanism for detecting and preventing loops from occurring in a
multi-bridged environment. When three or more LAN's segments are connected via bridges, a loop can occur. Because a bridge
forwards all packets that are not recognized as being local, some packets can circulate for long periods of time, eventually
degrading system performance. This algorithm ensures only one path connects any pair of stations, selecting one bridge as the
'root' bridge, with the highest priority one as identifier, from which all paths should radiate.
Spoofing
A method of fooling network end stations into believing that keep alive signals have come from and returned to the host. Polls are
received and returned locally at either end
Static IP Addresses
A static IP address is an IP address permanently assigned to computer in a TCP/IP network. Static IP addresses are usually assigned
to networked devices that are consistently accessed by multiple users, such as Server PCs, or printers. If you are using your Router to
share your cable or DSL Internet connection, contact your ISP to see if they have assigned your home a static IP address. You will
need that address during your Router's configuration.
Subnet
For routing purposes, IP networks can be divided into logical subnets by using a subnet mask. Values below those of the mask are
valid addresses on the subnet.
TCP
Transmission Control Protocol - The major transport protocol in the Internet suite of protocols provides reliable, connection-
oriented full-duplex streams.
TFTP
Trivial File Transfer Protocol - A simple file transfer protocol (a simplified version of FTP) that is often used to boot diskless
workstations and other network devices such as routers over a network (typically a LAN).
Telnet
The virtual terminal protocol in the Internet suite of protocols - Allows users of one host to log into a remote host and act as normal
terminal users of that host.
Transparent bridging
So named because the intelligence necessary to make relaying decisions exists in the bridge itself and is thus transparent to the
communicating workstations. It involves frame forwarding; learning workstation addresses and ensuring no topology loops exist (in
conjunction with the Spanning-Tree algorithm).
UDP
User Datagram Protocol - A connectionless transport protocol that runs on top of TCP/IP's IP. UDP, like TCP, uses IP for delivery;
however, unlike TCP, UDP provides for exchange of datagrams without acknowledgments or guaranteed delivery. Best suited for
small, independent requests, such as requesting a MIB value from an SNMP agent, in which first setting up a connection would take
more time than sending the data.
UNI signaling
User Network Interface signaling for ATM communications.
