Applications, such as TFTP, may add rudimentary reliability mechanisms into the application layer as needed. [6] If an application requires a high degree of reliability, a protocol such as the Transmission Control Protocol may be used instead. Most often, UDP applications do not employ reliability mechanisms and may even be hindered by them.
In computer networking, the Reliable User Datagram Protocol (RUDP) is a transport layer protocol designed at Bell Labs for the Plan 9 operating system.It aims to provide a solution where UDP is too primitive because guaranteed-order packet delivery is desirable, but TCP adds too much complexity/overhead.
NORM operates on top of the User Datagram Protocol (UDP), and ensures reliable communication based upon a negative acknowledgement (NACK), selective Automatic Repeat Request (ARQ) mechanism, as opposed to the positive acknowledgement (ACK) approach that the standard Transmission Control Protocol (TCP) uses. In other words, receivers using NORM ...
Together, Transmission Control Protocol (TCP) and IP provide a reliable service, whereas User Datagram Protocol (UDP) and IP provide an unreliable one. In the context of distributed protocols, reliability properties specify the guarantees that the protocol provides with respect to the delivery of messages to the intended recipient(s).
Reliability in iWARP is given by the protocol itself, as TCP is reliable. RoCEv2 on the other hand utilizes UDP which has a far smaller overhead and better performance but does not provide inherent reliability, and therefore reliability must be implemented alongside RoCEv2. One solution is to use converged Ethernet switches to make the local ...
The Inter-Control Center Communications Protocol (ICCP or IEC 60870-6/TASE.2) [3] is being specified by utility organizations throughout the world to provide data exchange over wide area networks (WANs) between utility control centers, utilities, power pools, regional control centers, and Non-Utility Generators.
[1] [2] Multicast, low overhead, and simplicity are important for Internet of things (IoT) and machine-to-machine (M2M) communication, which tend to be embedded and have much less memory and power supply than traditional Internet devices have. Therefore, efficiency is very important. CoAP can run on most devices that support UDP or a UDP analogue.
Connectionless communication, often referred to as CL-mode communication, [1] is a data transmission method used in packet switching networks, using data packets that are frequently called datagrams, in which each data packet is individually addressed and routed based on information carried in each packet, rather than in the setup information of a prearranged, fixed data channel as in ...
