Glossary 713
thinnet Also called 10Base2. Bus network that uses a thin coax cable and
runs Ethernet media access up to 185 meters.
token A frame containing only control information. Possessing this control
information gives a network device permission to transmit data onto the
network. See also: token passing.
token bus LAN architecture that is the basis for the IEEE 802.4 LAN
specification and employs token passing access over a bus topology. See also:
IEEE.
token passing A method used by network devices to access the physical
medium in a systematic way based on possession of a small frame called a
token. See also: token.
Token Ring IBM’s token-passing LAN technology. It runs at 4Mbps or
16Mbps over a ring topology. Defined formally by IEEE 802.5. See also: ring
topology and token passing.
toll network WAN network that uses the Public Switched Telephone Network
(PSTN) to send packets.
trace IP command used to trace the path a packet takes through an
internetwork.
transparent bridging The bridging scheme used in Ethernet and IEEE
802.3 networks, it passes frames along one hop at a time, using bridging
information stored in tables that associate end-node MAC addresses within
bridge ports. This type of bridging is considered transparent because the
source node does not know it has been bridged, because the destination
frames are sent directly to the end node. Contrast with: SRB.
Transport layer Layer 4 of the OSI reference model, used for reliable communication
between end nodes over the network. The Transport layer provides
mechanisms used for establishing, maintaining, and terminating virtual
circuits, transport fault detection and recovery, and controlling the flow of
information. See also: Application layer, Data Link layer, Network layer,
Physical layer, Presentation layer, and Session layer.
