1. In a packet-switched network, transmission in which each packet is encoded with a header containing a destination address sufficient to permit the independent delivery of the packet without the aid of additional instructions.
Note 1: A packet transmitted in a connectionless mode is frequently called a datagram.
Note 2: In connectionless mode transmission of a packet, the service provider… (Read More →)

A network service that transfers information between end users without establishing a logical connection or virtual circuit between those specific users. [After T1.110-1987]

A service that allows the transfer of information among subscribers without the need for end-to-end establishment procedures. [T1.629-1999]

See connectionless mode transmission.

1. A unit of traffic measurement expressed as the number of connections established at a switching point per hour.
2. A unit of traffic measurement used to express the rate at which circuits are established at a switch.
Note: The magnitude of the CCH is an instantaneous value subject to change as a function of time, i.e., from moment to… (Read More →)

For nodes (or links), the minimum number of nodes (or links) whose removal results in losing all paths that can be used to transfer information from a source to a sink. [T
1. Rpt24-1993]

In an adaptive or manually operated high-frequency (HF) radio network, the automatic or manual exchange of information concerning routes to stations that are not directly reachable by the exchange originator.
Note: The purpose of the exchange is to identify indirect paths and/or possible relay stations to those stations that are not directly reachable.

A device for mating and demating electrical power connections or communications media.
Note: A connector is distinguished from a splice, which is a permanent yyjoint.

A basic principle of optics, that no passive optical system can increase the quantity L/n2, where L is the radiance of a beam and n is the local refractive index.
Note: "Conservation of radiance" was formerly called "conservation of brightness" or the "brightness theorem. "
