ARINC 818 (Avionics Digital Video Bus) is a point-to-point, 8b/10b-encoded (or 64B/66B for higher speeds) serial protocol for transmission of video, audio, and data. The protocol is packetized but is video-centric and very flexible, supporting an array of complex video functions including the multiplexing of multiple video streams on a single link or the transmission of a single stream over a ...
InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency.It is used for data interconnect both among and within computers.
UPI is a low-latency coherent interconnect for scalable multiprocessor systems with a shared address space. It uses a directory-based home snoop coherency protocol with a transfer speed of up to 10.4 GT/s. Supporting processors typically have two or three UPI links.
There are two kinds of write commands supported: posted and non-posted. Posted writes do not require a response from the target. This is usually used for high bandwidth devices such as uniform memory access traffic or direct memory access transfers. Non-posted writes require a response from the receiver in the form of a "target done" response.
The worst-case latency requirement is defined as 2 ms for Class A and 50 ms for Class B, but has been shown to be unreliable. [ 5 ] [ 6 ] The per-port peer delay provided by gPTP and the network bridge residence delay are added to calculate the accumulated delays and ensure the latency requirement is met.
In data communications, the bandwidth-delay product is the product of a data link's capacity (in bits per second) and its round-trip delay time (in seconds). [1] The result, an amount of data measured in bits (or bytes), is equivalent to the maximum amount of data on the network circuit at any given time, i.e., data that has been transmitted but not yet acknowledged.
The TCDL can accept data from many different sources, then encrypt, multiplex, encode, transmit, demultiplex, and route this data at high speeds. It uses a K u narrowband uplink that is used for both payload and vehicle control, and a wideband downlink for data transfer.
Network Device Interface (NDI) is a software specification developed by the technology company NewTek.It enables high-definition video to be transmitted, received, and communicated over a computer network with low latency and high quality.
