TFTP

See “TLS” on page 20.

TLS

Short for Transport Layer Security, TLS is a protocol that guarantees privacy and data integrity between

client/server applications communicating over the Internet.

The TLS protocol is made up of two layers. The TLS Record Protocol ensures that a connection is private by

using symmetric data encryption and ensures that the connection is reliable. The second TLS layer is the

TLS Handshake Protocol, which allows authentication between the server and client and the negotiation of

an encryption algorithm and cryptographic keys before data is transmitted or received. Based on Netscape’s

SSL 3.0, TLS supercedes and is an extension of SSL. TLS and SSL are not interoperable.

Telnet

A TCP/IP application protocol that provides a virtual terminal service, allowing a user to log into another

computer system and access a device as if the user were connected directly to the device.

Traffic prioritization

Giving time-critical data traffic a higher quality of service over other, non-critical data traffic.

Trivial File Transfer Protocol

TFTP is a simple form of the File Transfer Protocol (FTP). TFTP uses the User Datagram Protocol (UDP, a

direct protocol used to communicate datagrams over a network with little error recovery) and provides no

security features. It is often used by servers to boot diskless workstations, X-terminals, and routers.

Trunking

The process of combing a set of trunks that are traffic-engineered as a unit for the establishment of

connections between switching systems in which all of the communications paths are interchangeable.

UTP

Unshielded twisted pair is the cable used by 10BASE-T and 100BASE-Tx Ethernet networks.

Virtual Local Area Network

Operating at the Data Link Layer (Layer 2 of the OSI model), the VLAN is a means of parsing a single

network into logical user groups or organizations, as if they physically resided on a dedicated LAN segment

of their own. In reality, this virtually defined community may have individual members peppered across a

large, extended LAN. The VLAN identifier is part of the 802.1Q tag, which is added to an Ethernet frame by
