The Linux kernel packet scheduler is an integral part of the Linux kernel's network stack and manages the transmit and receive ring buffers of all NICs. The packet scheduler is configured using the utility called tc (short for traffic control ).
A method of flow control in which a receiver gives a transmitter permission to transmit data until a window is full. When the window is full, the transmitter must stop transmitting until the receiver advertises a larger window. [5] Sliding-window flow control is best utilized when the buffer size is limited and pre-established.
This USART has a 3-byte receive buffer and a 1-byte transmit buffer. It has hardware to accelerate the processing of HDLC and SDLC. The CMOS version (Z85C30) provides signals to allow a third party DMA controller to perform DMA transfers. It can do asynchronous, byte level synchronous, and bit level synchronous communications.

A digital buffer (or a logic buffer) is an electronic circuit element used to copy a digital input signal and isolate it from any output load.For the typical case of using voltages as logic signals, a logic buffer's input impedance is high, so it draws little current from the input circuit, to avoid disturbing its signal.
Large receive offload (LRO) is a technique for increasing inbound throughput of high-bandwidth network connections by reducing central processing unit (CPU) overhead. It works by aggregating multiple incoming packets from a single stream into a larger buffer before they are passed higher up the networking stack, thus reducing the number of ...
Whenever the transmitter has data to send, it may transmit up to w t packets ahead of the latest acknowledgment n a. That is, it may transmit packet number n t as long as n t < n a +w t. In the absence of a communication error, the transmitter soon receives an acknowledgment for all the packets it has sent, leaving n a equal to n t.
The original TCP configurations supported TCP receive window size buffers of up to 65,535 (64 KiB - 1) bytes, which was adequate for slow links or links with small RTTs. Larger buffers are required by the high performance options described below. Buffering is used throughout high performance network systems to handle delays in the system.
The Wardenclyffe Power Plant prototype, intended by Nikola Tesla to be a "World Wireless" telecommunications facility.. The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors.
