TCP Offload Engine (TOE)

An intelligent hardware interface to a network. A TOE is capable of processing TCP and IP packets on behalf of the host CPU. A TOE is installed in the PCI bus, Sbus, or other expansion bus of a host.



TCP port number

A 16-bit identifier assigned by IANA to each well-known session layer protocol that operates over TCP. Each port number that IANA assigns may be used by TCP or UDP. Unassigned port numbers may be used by vendors to identify their own proprietary session layer protocols. A range of port numbers is reserved for use by clients to initiate TCP connections to servers.



TCP sliding window

The mechanism by which a host dynamically updates its peer host regarding the current size of its receive buffer.



TCP socket

A connection end-point identifier derived by concatenating the IP address of a host with the port number of a session layer protocol within the host.



third party copy (3PC)

The predecessor to the SCSI-3 EXTENDED COPY command.



Time Division Multiplexing (TDM)

A technique for multiplexing signals onto a shared medium in which the full bandwidth of the medium is allotted to each source sequentially for a fixed and limited period of time.



Top Level Domain (TLD)

A domain within the Domain Name System (DNS) that resides immediately under the root domain.



traffic analyzer

A product that inspects frame headers and payloads to generate network performance reports.



traffic capture

The process of capturing frames in transit for further analysis.



traffic flow confidentiality

A security service that prevents exposure of communication parameters (such as original source and destination addresses) to unauthorized parties.



Transmission Control Block (TCB)

A small area in memory used to maintain the state of each TCP connection.



transmission rate

The rate at which bits are serialized onto a link.



trunk

A link between two switches.



trunking

The process of tagging frames before transmission on an ISL to indicate the VLAN or VSAN membership of each frame.



Type of Service (ToS)

A field in the IP Header that was previously used to specify Quality of Service (QoS) requirements on a per-packet basis. This field was redefined in RFC 2474 as the Differentiated Services (DiffServ) field.
