T
TCP/IP Transmission Control Protocol / Internet Protocol – A standard for networking
over unreliable transmission paths. See also UDP.
TDM Time Division Multiplexing – A method of multiplexing that provides the
transmission of two or more signals on the same communication path or chan-
nel, but at different times by utilizing recurrent timeslots.
TFTP Trivial File Transfer Protocol – A simple file transfer protocol used over reli-

UDP User Datagram Protocol – A standard for networking over reliable transmission
paths.
UDP
multicast
A multicast transmission using the UDP protocol.
Unicast Transmitting information/data packets to a single destination on the IP network.
V
VESP Vipersat External Switching Protocol – A switch-request protocol that allows
external VPN equipment and Real-time proprietary applications to negotiate
bandwidth requests between any two subnets on a Vipersat network. VESP is
used by newer Vipersat modems (e.g., SLM-5650A) to send a switch request to
the VMS to establish a new satellite link or adjust bandwidth for an existing
link.
VCS Vipersat Circuit Scheduler – A proprietary satellite communication scheduling
system used to schedule Vipersat network resources in support of a variety of
high-priority applications such as video conferencing and scheduled broadcast-
ing.
