connectionless


Also found in: Medical, Acronyms.

connectionless

A communications architecture that does not require the establishment of a session between two nodes before transmission can begin. For example, the transmission of frames within a local area network (LAN), such as Ethernet, Token Ring and FDDI, is connectionless. As soon as a frame has been constructed, it is inserted into the network (put on the wire).

In an IP network, the UDP transport protocol, which is used for voice over IP (VoIP) and video calling, is connectionless. Contrast with connection oriented. See UDP.

The Steam'N'Hold system also eliminates water and drain lines and regular treatment of scale and established a new category of products called connectionless steamers.
Anycast is best suited to connectionless protocols like UDP, rather than connection-oriented protocols such as TCP, since the receiver selected for any given source may change from time to time as optimal routes change.
A young competitor named Cisco systems was having success with an alternative approach, sending traffic over a wide area network by replacing the one-to-one SNA 'session' links with connectionless links.
For connectionless protocols such as UDP, the platform verifies communication symmetry, making sure the traffic appears to be a legitimate conversation.
Additionally, "due to the simple and connectionless setup, such a system is easy for non-specialists to use," says Gu.
Part of this fragility results from the connectionless nature of IP where IP ports can burst to the full line rate, thereby affecting other IP data flows competing for service on that IP network.

Using the expression for the BER of Equation 3, the frame error rate (FER) in asynchronous connectionless (ACL) packets of Bluetooth transmissions can be ascertained for different formats of the packet structures, which are represented in Table 1.
Because IP is connectionless, however, traceroute does not guarantee the discovered route was the actual route followed by a packet.
