switch On an Ethernet network, a switch filters frames based on the MAC address, in a manner similar to a

bridge. A switch is more advanced because it can connect more than two seg ments.

symbol rate Also known as baud rate, is a measure of the number of times per second a signal in a

communications channel varies, or makes a transition between states (states being frequencies,

voltage levels or phase angles). Usually measured in symbols per second ( sps).

SYSLOG A de-facto UNIX standard for logging system events.

TBCP Tagged Binary Communication Protocol

TCP Transmission Control Protocol on OSI transport layer four, provides reliable tran sport over the network

for data transmitted using IP (network layer three). It is an end-to-end protocol defining rules and

procedures for data exchange between hosts on top of connectionless IP. TCP uses a timer to track

outstanding packets, checks error in incoming packets, and retransmits packets if requested.

TCP/IP The Transmission Control Protocol/Internet Protocol suite provides standards and rules f or data

communication between networks on the Internet. It is the worldwide internetworking standard and the

basic communications protocol of the Internet.

TFTP Trivial File Transfer Protocol is a very simple protocol used to transfer files.

transparent

bridging

A method to enable all hosts on the wired Ethernet LAN, wireless LAN, HPNA LAN, and USB

connection to communicate as if they were all connected to the same phy sical network.

transport layer Layer of the OS I concerned with protocols for error recognition and recovery. This layer also regulate s

information flow.

trunk Electronic path over which date is transmitted.

TTL The time to live is the number of routers (or hops) a packet can traverse before being discarded. When

a router processes an packet, it decreases the TTL by 1. When the TTL reaches zer o, the packet is

discarded.

tunnel To place packets inside other packets to send over a network. The protocol of the enclosing packet is

understood by each endpoint, or tunnel interface, where the packet enters and exi ts the network.

VPNs rely on tunneling to create a secure network.

Tunneling requires the following protocol types:

•A carrier protocol, such as TCP, used by the network that the data travels over

•An encapsulating protocol, such as IPSec, L2F, L2TP, or PPTP, that is wrapped around the original

data

•A passenger protocol, such as IP, for the original data

two-way A cable system that can transmit signals in both direct ions to and from the headend and the

subscriber.
