Glossary

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.

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.

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

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.

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.

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

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 
an 802.1Q-compliant switch or router. Devices recognizing 802.1Q-tagged frames maintain appropriate 
tables to track VLANs. The first three bits of the 802.1Q tag are used by 802.1P to establish priority for the 
packet.
