Sapphire Rapids is a codename for Intel's server (fourth generation Xeon Scalable) and workstation (Xeon W-2400/2500 and Xeon W-3400/3500) processors based on the Golden Cove microarchitecture and produced using Intel 7.
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.
Network-intensive applications like networked storage or cluster computing need a network infrastructure with a high bandwidth and low latency. The advantages of RDMA over other network application programming interfaces such as Berkeley sockets are lower latency, lower CPU load and higher bandwidth. [ 6 ]
A satellite internet constellation is a constellation of artificial satellites providing satellite internet service.In particular, the term has come to refer to a new generation of very large constellations (sometimes referred to as megaconstellations [1]) orbiting in low Earth orbit (LEO) to provide low-latency, high bandwidth internet service.

Throughput is controlled by available bandwidth, as well as the available signal-to-noise ratio and hardware limitations. Throughput for the purpose of this article will be understood to be measured from the arrival of the first bit of data at the receiver, to decouple the concept of throughput from the concept of latency.
Different PHBs may be defined to offer, for example, low-loss or low-latency service. Rather than differentiating network traffic based on the requirements of an individual flow, DiffServ operates on the principle of traffic classification , placing each data packet into one of a limited number of traffic classes.
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.
