TCP segmentation offload


Abbreviated as TSO, TCP segmentation offload is used to reduce the CPU overhead of TCP/IP on fast networks. TSO breaks down large groups of data sent over a network into smaller segments that pass through all the network elements between the source and destination. This type of offload relies on the network interface controller (NIC) to segment the data and then add the TCP, IP and data link layer protocol headers to each segment. The NIC must support TSO. TSO is also called large segment offload (LSO).

  • TCQ

    Short for tagged command queuing, a method of processing requests from a host device to a hard drive that is storing the data requested. TCQ was first introduced with the SCSI-2 standard as a way to allow hard drives to accept multiple concurrent commands from a host PC. When commands arrive at the drive’s buffer, […]

  • TDM

    Short for Time Division Multiplexing, a type of multiplexing that combines data streams by assigning each stream a different time slot in a set. TDM repeatedly transmits a fixed sequence of time slots over a single transmission channel. Within T-Carrier systems, such as T-1 and T-3, TDM combines Pulse Code Modulated (PCM)streams created for each […]

  • TDMA

    Short for Time Division Multiple Access, a technology for delivering digital wireless service using time-division multiplexing (TDM). TDMA works by dividing a radio frequency into time slots and then allocating slots to multiple calls. In this way, a single frequency can support multiple, simultaneous data channels. TDMA is used by the GSM digital cellular system.

  • TDR

    Time Domain Reflectometry is used to pinpoint flaws and problems in underground and aerial wire, cabling, and fiber optics. Time Domain Reflectometers send a signal down the conductor and measure the time it takes for the signal — or part of the signal — to return. The signal’s reflection begins at the flaw point. Once […]

  • TEM

    Short for telecommunications equipment manufacturer.
