User Datagram Protocol, Virtual circuit | HP NetRider specification

UDP

User Datagram Protocol. A protocol that is the part of the Internet Protocol that provides datagram service. It distinguishes between multiple destinations on a host, allowing multiple application programs executing on a host to independently exchange (send and receive) datagrams with multiple application programs on another host.

User Datagram Protocol

See UDP.

virtual circuit

A logical communications path between a access server and a service node. A virtual circuit provides a bidirectional, sequential, timer-based, error-free stream of data.

WAN

Wide Area Network. A network composed of computers connected by communications links that cover distances up to many thousands of miles. Contrast with LAN.

Wide Area Network

See WAN.

XON/XOFF characters

These characters are used with a form of in-band flow control and are transmitted as TxD and RxD data.
